Samsung EX1/TL500 - small camera for professional people

Samsung EX1 is equipped with the most advanced technology today to compete with Canon and Panasonic cameras on the market segment of high-level tourism.

 
Samsung which is not a big name among the camera manufacturers for the mass market as well as the high ranking level. When the number of dots on the race or integrated features are becoming saturated, companies have discovered to their own direction with the idea as one of a kind integrated auxiliary display on compact line ST, PL or less strategic flip mirror to produce "hybrid SLR" NX10 ... Version luxury travel camera EX1 (or TL500 in the U.S. market) continue to show creativity equipped with Samsung's unique "wide angle lens like 24mm f/1.8 aperture, rotating flip screen AMOLED , two disk mode and select a series of other advanced features.

Samsung EX1 is slightly larger than the size of a little over two opponents with the same class as the Canon S90 and the Panasonic LX3. Body weight of about 360 grams (battery not included) should be considerably difficult if you want to insert it into the pants pocket when go travel. The entire surface area of the EX1 grip is coated with a soft rubber ball is still slowing. When holding machine definitely feeling very slippery and not easy as S90 or LX3.

The front of the machine have an extra gear to help change the exposure in manual mode and shutter priority as the real DSLR. In addition, users can click on this gear to activate exposure compensation. This is a very innovative feature on the EX1, to help speed up operation and reduce errors by pressing the wrong button in quick shooting situations. On the grip, Samsung also more thoroughly integrated infrared sensor compatible with some of its remote control.

The top of the EX1 is to select two disks rotate, which, helped drive out the switching between the shooting modes and basic disk, the inner side assumed the role as the boot source, timer, single shot / continuous shooting and BKT (bracketing) used for HDR. Flashes sinking mechanism works much like the Canon S90 but instead controls the menu on the screen as competitors, users can turn off lights with mechanical buttons quite easily and quickly. Experimental fact that, due to the small size and slightly lower than the flip side of the machine but EX1 flash bright enough only to ensure at a distance of nearly three meters when setting ISO 100. If still not satisfied, users can mount more lights left on base as the line ED-SEF20A hotshoe flashgun capital for NX10 hybrid camera.

The rear EX1 a little bit tight due to the big screen have been eating and auxiliary button. However, the control system of the machine is extremely easy to get to know the layout of function keys relatively scientific and fairly intuitive menu design. EX1 provides 13 default scene, including some interesting modes like Beauty Shot help identify and then handle the brightness and color across the face, Frame Guide helps make available to another angle, only the base and press machine ... Machine support relative to the manual mode allows the selection of autofocus points in a frame and zoom the image when the user wants to focus manually. EX1 owners versatile swivel flip screen size 3 inches and resolutions up to 614,000 pixels, the largest in number of tourist cameras available on the market today. Combined with proprietary technology AMODLED Samsung, this monitor is capable of re-detail, color and contrast superior to traditional generation LCD. Display quality and viewing angle is still guaranteed even better in bright environments such as the sun or in the lab.

With ambitions to compete with "big brand" Canon and Panasonic in the segment of luxury travel camera, Samsung EX1 is equipped with the advanced technology available today. CCD-megapixel resolution, but only 10 have sizes up to 1 / 1, 7 inch, equivalent rivals Canon S90 (or G11) and only slightly smaller than the Panasonic LX3. Most of the features on the EX1 is a system of Schneider-Kreuznach lens with focal length ranging from 24mm wide angle to telephoto 72mm, with optical stabilization. Compared with the lens fitted on two versions of S90 and G11 with the focal length in turn is 28-135mm and 28-140mm, Samsung EX1 quite limited in their ability and shooting range layout but has the advantage than when faced with large areas of landscape. Because the focal length starting from 24mm 3x zoom of the EX1 should also allow the capture a bit more flexible compared to 2.5 x the LX3. In addition, Samsung EX1 also owns a large aperture lens is "horrified" f/1.8 and f/2.4 at the widest angle when maximum zoom, extra strength to fight off any rivals any in its segment. Aperture big advantage not only helps get the machine stable when shooting low light, but also a serious increase in the effective background shots clear of pressing need, which is a strength only on the camera lens series left. Samsung EX1 also allows users to save files as RAW as the Canon S90, G11 and Panasonic LX3.

According Dpreview, the EX1 lens optical quality is quite good. Average distortion 2.6% at the widest angle of 24mm and almost negligible when the maximum of 3x zoom. If you save files as JPEG compression, the machine will automatically reduce the user of this error should not worry almost to the processing software. Images lack contrast when shooting steam outdoors. Metering works very unstable so you should consider using more features exposure compensation in case of necessity. The color processor reproduced fairly accurately with the neutral component, not too bright or too dull. Noise reduction capability of the machine operation is also very impressive. Images are still quite smooth and when to raise the ISO to 800. At higher sensitivity, reducing noise of the EX1 mechanism works only at an average rate should remain fairly sharp images, not smooth like the Canon S90 or appearing too much like Panasonic LX3 hotel. A little interference as colored precipitates appear in dark image areas to raise the ISO to 800 but this bug is still acceptable.

Samsung EX1 support video recording with image quality is quite good but the resolution just stop at VGA (640 x 480 pixels, 30 frames per second) and single-channel sound (mono). Battery life is quite high, about 250 types of Photographyblog test image and can be recharged at any computer via a USB connection.

With significant upgrades to their form as well as technology equipment inside, Samsung EX1 is a "new star" on tourism market advanced camera next to names waver from Panasonic or Canon. Machine is a rugged, bright screen, open the large lens, long battery life and is far more better quality pictures even in low light conditions. Apart from some minor bugs related to metering and flash, EX1 deserves the number one choice for professional users besides DSLR cumbersome and complex.

Although equipped with features such as LED flash, auto-capture capability, night shooting, panorama shooting or continuous shooting, but the camera's resolution is not high, plus the lack of auto travel dynamic focus (autofocus), pictures taken by Nokia C5 only average quality.

Besides, the video features of the C5 also stop at the level of "entertainment" is the key. With only supports VGA video frame rate 15 fps, the C5 is only relevant video presentation on mobile devices small screen.

String.contains and String.indexOf

To check if a string contains a substring, I usually use:

if(s.indexOf(sub) >= 0)

For JDK 5 or later, a contains method can also be used, which seems to be a little more readable:

if(s.contains(sub))

The signature of contains method is:

public boolean contains(java.lang.CharSequence s);

Note that CharSequence is a super-interface of String, StringBuffer, StringBuilder, java.nio.CharBuffer, javax.swing.text.Segment. So you can pass any of the 5 types to contains method.

The current implementation of contains method just convert the param to String and calls indexOf.

NEX-3- Sony's break through

There are compact body as compact but Sony NEX-3 for good image quality just as well compared with some DSLR models.

After a long time "ambiguous" about their project from the PMA photo show, Sony was finally officially announced the camera sometimes "super-compact" with the ability to replace the lens as though the line DSLR no mirror to flip, just past mid-May. This is indeed a daring moves that Japanese manufacturers made to compete with the format lens reflex digital camera is different in the market Micro Four Thirds camera lens can be replaced but the price comfortable more and more compact size.

Was released along with the NEX-5, but NEX-3 is lower than the version with the ability to shoot 720p HD video resolution of 1280 x 720 pixels at 30 frames per second than 1080i AVCHD Full HD resolution 1920 x 1080 pixels of the NEX-5. However, both models have the same HD image sensor APS Exmor CMOS Sensor (23.4 × 15.6 mm) 14.1 megapixel resolution.

NEX-3 compact size almost equivalent to the machine for travel weighing only about 297 grams of whole body and less than 500 grams when fitted with 18-55 mm lens. When you try mount 18-55mm f/3.5-5.6 lens, machine still feels sure when handling birds with one hand although the focus is skewed slightly to the left and the grip is not really optimized for use as DSLR.

An interesting addition in the NEX-3 is a screen of this model can be turned down 45 degree angle and rotation angle of 80 degrees above. With this versatile screen, users can comfortably compose in cases of difficult shooting situations. Although there is no interactive touch, but this screen is equipped with Sony to 921,600 pixel resolution. Through testing, the display is quite good under sunlight, clear and not misleading in color.

To reduce weight, size, NEX-3 are respectively flip-down mirror frame and no sight. This defect can be considered negligible because the Sony direction of their products to users familiar only with the compact simple to use but want to have superior image quality. In addition, NEX-3 also has an accessory port on the flash to help add more or viewfinder. Although the mechanism is quite clever removable but users will still need time to get familiar with the many stages of this.

Like the other compacts, NEX-3 little buttons, making operation of the machine parameters change in the regime, especially manual mode is complex. Aperture and shutter speed can be adjusted through the two navigation buttons but ISO and other parameters need to click through to the last few times can be changed as desired. In this case, the Auto function will probably always be the choice of the user familiar.

NEX-third to nearly two seconds from power on to the first photo shoot. When Auto Mode Review (auto review right after image capture), then this camera is quite slow with two seconds more time to be able to shoot the next picture.

Image quality of Sony NEX-3 are commendable indeed. Very sharp image, especially when using the daylight, the contrast is quite good and comparable with many DSLR models available in the market today.

However, the most prominent point in the NEX-3 to speak to is able to reduce noise. Sony's camera almost eat off all the other Micro Four Thirds model. In experimental tests taken under neon lights in the room, NEX-3 for a stable image quality from ISO 200 to 800 level, while to the 1600 level, noise starts to appear, the image is still usable even at ISO 6400 and details are still visible at ISO12.800.

Java debug options in ant build.xml

To add debug options to java (Sun's JDK) command line:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9009

If the java process runs and terminates itself, change suspend=y, so you can have a chance to attach the remote debugger.

To add the same debug options to ant build.xml java task:

<target name="run">
 <java fork="on"
       failonerror="true"
       classpath="xxx"
       classname="xxx">
     <jvmarg line="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009" />
     <arg line="--arg1 arg2 --arg3 arg4"/>
  </java>
</target>

Or, with the newer -agentlib option:

<target name="test" depends="compile">
    <junit printsummary="yes" haltonerror="no" haltonfailure="no" fork="true">
      <formatter type="plain" usefile="false"/>
      <formatter type="xml"/>
      <test name="FooBeanTest"
          todir="xxx"/>
      <jvmarg line="-agentlib:jdwp=transport=dt_socket,address=localhost:9009,server=y,suspend=y" />
      <classpath>
        <path refid="test.compile.classpath"/>
        <path refid="javaee.classpath"/>
        <pathelement path="${build.dir}"/>
        <pathelement path="${junit.jar}"/>
      </classpath>
    </junit>
  </target>

Note: <arg> and <jvmarg> take either line or value attribute, but value attributes are treated as one single argument that may contain spaces. So in our case line attribute is used to specify multiple arguments separated by spaces. If value attribute was used instead of line attribute, the debug options will not take effect.

Panasonic DMC-FH20 handy for everyone

Panasonic has equipped FH20 large optical zoom while maintaining his fragile body together with a range of features to automatically detect scene.

On the basic configuration, the DMC-FH20 also not bad compared to the competitor with resolution 14.1 million pixels, 8x optical zoom (28 - 224mm) lens with moderate wide-angle and mechanisms optical stabilization, 2.7 inch LCD 230,000 pixels and Macro shooting capability with a minimum 5cm.

Square design, classic, DMC-FH20 youthful looks and new technology style with four color choices. The front consists only of the lens, flash and focus assist lamp. Optical viewfinder has been removed, instead all operations will be done through LCD screen. With moderate quality, only 230,000 pixels as the vast majority of other travel machine, the DMC-FH20 enough to frame and review photos and video, rather than bringing a quality difference.

Besides the majority of LCD monitors in the back is the Edit button basic parameters are very familiar and easy to use, almost similar to the lifetime of the machine even if different vendors such as flash adjustment, adjustment mode, adjust exposure compensation, auto capture and switch screen. Mode button is designed to leave with the ability to convert normal video mode, the default scene, or custom video. Button gotten between shooting modes and playback are arranged as a switch, a little inconvenient, while the new generation often use electronic button for users who want to move fast on small mode just shutter instead of moving images such as the switch on this version.

On the above, the DMC-FH20 is also relatively simple design with power switch, camera button and zoom ring combination, it is next iA button allows fast transfer of the intelligent mode. This mode allows the user to select between six default mode as intelligent portrait (i-Portrait), landscape (i-Scenery), macro shot, taken at night (i-Night Portrait) ... very suitable for adjustment problems or those new to photography.

Panasonic's menu system is simple, relatively easy to understand and not take a long time familiar. Besides the traditional menu system, with Q. Menu button, users can quickly access to the basic parameters of the machine easily through the system of symbols, quite easily even with people who do not know much English.

Continuous shooting mode of FH20 basically achieved 1.5 frames per second, but in case of need speed, the shooting can lower the resolution down to 3 million pixels to achieve 4.6 frames per second. Especially with the default scene, the shooting can freely choose between the default 25 setting scenes, meet the most common situations, though sometimes also makes people more options the user should select wonder what mode is most appropriate.

Keeping up with the new generation this year, Panasonic has also equipped for video-recording capabilities FH20 HD 1280 x 720 pixels at 30 frames per second but still use the QuickTime format MPEG more compact instead of AVCHD. Although the video quality of HD but only average, but just enough resolution process serrated less. In addition, no optical zoom during filming and recording mono instead of stereo is also an inherent weakness of the tourism machine that FH20 is no exception. One other point that is a little inconvenient shooting mode button will not be separated as many different versions that must be accessed through the navigation menu makes somewhat more complicated.

The quality of outdoor photos FH20 nothing to complain. With enough light, bright colors show, details, contrast, keep the area reasonably bright and dark areas. Speed of operation is also found on average to focus only time 0.011 seconds, boot time is about 1.7 seconds.

In automatic mode, white balance, color FH20 warm bias, while if the manual switch back into cold air. Flash operation at the average from approximately 3 meters, but the light is pretty fast recovery time, only around 3 to 4 seconds.

Lens quality is excellent on FH20 not as expected. In the test images, sharpness achieved only in the central area, as the edge image sharpness falling. At telephoto focal length even at the center sharpness also started to recognize the decline. Image distortion is inevitable when fully extended lens size and only slightly lower at telephoto focal lengths. Interfering particles, although well-controlled but also from ISO 80 to 200, and 400 or more from the strip appeared much noise as reduced quality and loss of image details.

However, when considering the price of FH20, see the product line this valuable features such activity was quite reasonable. In terms of configuration, large optical zoom while maintaining his fragile body together with a range of features that automatically detect scene Panasonic equipment, FH20 can say is popular enough version suitable for the majority of users can access the technological advances of the digital photography without spending too much cost.

LE5500 - HDTV super slim from LG

Fashion design with slim new figure is the point of interest on the LG model LE5500.

While Sony and Samsung are massively released the new 2010 models on the market early in the LG again made plans to release droplets of each new 2010 model. Right to the middle of this year, LG launched a new HDTV model 2010 its first LED, LE5500 model with three different screen sizes are 37, 42 and 47 inches.

Not to mention the features and performance show, the first points of interest include the LG LE5500 is a super slim design. The use of LED screen with borders helped LG LE5500 is a delicate looks very fashionable. With body thickness less than 28 mm, the new LED LG is one of the thinnest HDTV today. However, LG has a little bit less subtle when choosing colors for the cover. Screen design borders the black paint mixed purple red bands is not enough to stand out product completely in countless fashion current HDTV models. Compared with the sample design of the Samsung 2009 LED life B7000, LG LE5500 still more weak.

Comes with display stand is a rectangular thin, designed to synchronize with the screen and is capable of rotating in different directions. All the main port on the TV are concealed behind the screen, leaving only the side of including extra USB ports, HDMI and composite, service needs screen hanging on the walls of many customers .

LED plus- LED edge system with fuzzy control cloudy dark local technical that feature is most noticeable technology on LG's new HDTV models. With structure LED plus, each screen 42 inch or 47 inch model LE5500 will own 12 independent regions of different light lead, private ownership model 55 inch to 16 different areas, improving the quality of screen performance image, especially brightness and contrast.

In addition, the new model of property also features LG  " LG Wireless Media Box" and network connections. In particular, LG Wirle Media Box helps users remove the zigzag signal cable system with HDMI connected devices and other standards through wireless communication. As for networking, instead of using Wi-Fi antenna integrated manufacturer LE5500 only provide the ability to access online data through the Ethernet port, or from devices left Wi-Fi wave using the USB port.

Although equipped with LED Plus technology, but the ability of the LE5500 performed only on relatively level. The depth of the black strips on screen LG has not lost the impression of its advertising. Compared with model EX700 and Sony or Samsung B7000, LG's products has proved to be a little bit brighter when the can is a dark scene. Meanwhile, the phenomenon of light openings (Blooming) also appears quite clearly in CNET's tests. The dark areas at the edge of the screen is still quite bright compared to the center, indicating LED Plus can not make the contrast of the screen to achieve the optimum.

In return for the ability to show the contrast is not very good, LE5500 is the ability to form LED screen color reproduction is quite perfect. Quality LED colors on the LG model proved absolutely outstanding compared to most conventional LCD models, but compared to other models of Samsung LED or Sony, CNET LE5500 also be evaluated as marginally expressed slightly more relatively accurate color tones and image quality is very smooth.

Missing in THX mode, only Cinema mode makes images LE5500 not meet the expectations of the faithful love movies. Property features and the ability to broadcast 1080p/24 with ability scan but show movies on the new LED LG still can not marginally more than some 60 Hz models. After, testing with a few action movies like "I Am Legend", CNet said in a fast-moving scenes, the screen sometimes encounter the phenomenon of delay and flicker if you turn on 1080p/24. But surprise, when turned off, the LE5500 has run pretty smooth.

Like many of Sony and Samsung products, the ability to save energy is one of the features that LG would like to emphasize on the LE5500. Along with the LED screen technology, intelligent sensor automatically adjusts the light emitted has helped to reduce the screen of the LG is more power consumption. Compared to the G10 46-inch model of Panasonic Plasma, 47 inch LE5500 energy efficiency three times and just take a little worse than the sample green screen 42-inch Sony EX700.

If you do not really enhance your ability to show images, a desire to own an affordable LED HDTV models, low power consumption with ultra-thin fashion design, LE5500 is a pretty reasonable product.
