Steve's Conclusion on Nikon Coolpix 5200
New for 2004, the Coolpix 5200 is an ultra-compact camera that packs a 5.1-megapixel imager and a Nikkor ED 3x optical zoom lens, in a durable all metal body. It offers users point-n-shoot simplicity with its "Auto" exposure mode, and allows you to explore your creative side with its wide variety of pre- programmed scene modes. Its scene-assisted modes (Portrait, Landscape, Sports, Night Portrait) display framing assist outlines on the LCD to ensure proper framing and you get the optimum exposure for select shooting conditions.
The ergonomics of the 5200 are great. Despite its very compact size, the well-shaped handgrip makes it easy to hold and one-handed shooting is a breeze. Controls are well placed and functional, and the menu system is logically organized. The 1.5-inch color LCD is used for image review, preview, access the settings menus and also serves as the camera's data display. This is a high quality display with a real-time refresh rate, and I found it was quite usable outdoors in bright sunlight. I was also impressed with its usability in low-light conditions as the display "gains up" to give you a brighter view, which is crucial when using the LCD to frame your subject(s) in these conditions.
The shooting performance of the 5200 was good. Power up to first image captured measured just under 4 seconds. Shutter lag measured a fast 1/10 of a second when pre-focused and 6/10 of a second including autofocus. The shot to shot time averaged about 1.8 seconds between frames without the use of the flash and approx. 2.5 seconds with the flash. The 5200 offers three Sequential shooting mode to choose from (Continuous, 5 shot buffer, Multi- shot 16.) Continuous mode was very respectable, I was able to capture 9 frames in about 3.5 seconds. When using the 5 shot buffer mode, you can capture several images, but the camera stores only the last 5 frames. In 5 shot buffer mode, I captured 5 frames in about 2 seconds. Multi-shot mode captures 16 frames, then makes a single 5M/Fine image out of all 16 frames. Using this mode, I was able to capture 16 frames in approx. 4.5 seconds. All test were done using a Sandisk 256MB Ultra II SD card, using 5M/Fine size/quality, with the use of the flash, and all other settings at default (unless otherwise noted.) Times may vary depending on lighting conditions, camera settings, media, etc.
The Nikkor ED 3x zoom lens is sharp and you should have no problem focusing in low-ambient lighting conditions thanks to the camera's focus-assist lamp. For some "unknown" reason, many manufactures still don't use these on their cameras. The lens has excellent macro coverage down to about 1.6 inches, and exhibits moderate barrel distortion at full wide-angle but is relatively free of pincushioning at full telephoto. The zoom and focus mechanisms move smoothly and quietly through their range. Its 38-114mm (35mm-equivalent) optical zoom range is typical for a camera in this class, offering a sufficient field of view for portraits of individuals, small groups, and landscape shots, and enough telephoto magnification to bring your subject closer.
I was happy with the overall image quality in 5M/Fine mode. When using the camera outdoors, I found that most of our samples were sharp and colors were nicely saturated. Looking at our sample of the restaurant, I did notice a little softness on the left hand side, but nothing a little sharpening in a digital image editor won't take care of. I was also pleased with our indoor test shots, the images are well exposed and skin tones look very natural. When taking pictures using the redeye reduction flash mode, you will notice that sometimes the in-camera redeye removal changes small red "things" or objects in the picture. You can see what I mean by looking at the two samples below. The necklace has small red beads that the camera thought was redeye, and changed them to a dark brown or blackish color. The other sample is where we tired to "fool" the camera -- it didn't work. We saw virtually no occurence of red-eye in our "people" pictures so we must conclude that Nikon's in-camera red-eye removal definitely works.
The camera is powered by the supplied proprietary Nikon EN-EL5 Li-ion rechargeable battery pack. Nikon claims that a fully-charged EN-EL5 pack can take approx. 150 shots with the flash used 50% of the time. I had no problem taking about 80 test shots one afternoon (using the LCD 100% of the time and the flash 25% of the time) and doing all of our other tests, before the camera indicated that the battery was exhausted.
Bottom line - the Coolpix 5200 is a great all-around camera. This camera will please the less experienced as well as the intermediate user and thanks to its compact size and light weight, you can carry it almost anywhere. And if you like to record movies, you'll love the ability to record VGA-size (640x480) videos at 30fps with audio - just make sure that you have a large SD card. Its 5 megapixel Fine images have plenty of resolution to create photo-quality prints up to 13x19-inch. I feel this would be a great camera for the family, business, or "tourist" user and with all of its scene modes, you'll always be ready to capture that special moment, no matter what the shooting conditions are.

Steve's Conclusion on Sony W-1
The Sony Cyber-shot DSC-W1 is a compact and durable camera that's loaded with powerful features such as a Carl Zeiss 3x optical zoom lens and a high resolution 5-megapixel imager. The W1 is easy to use in the Auto or Program AE exposure modes and when you want to exercise your creative side, you can simply rotate the mode dial to the desired shooting mode. With the ability to choose from five different image sizes, the camera offers versatility for all types of applications. The 3:2 mode is perfect for capturing images without having to worry about cropping them for creating 4x6-inch prints. Shooting in 1MP mode is great for sending pictures via e-mail or posting listings at online auctions.
One of the most noticeable features of the W1 is the 2.5-inch TFT color LCD. I was impressed with the LCD's performance when using it in bright light conditions, the menu screens were legible and framing was no problem, even with Florida's bright sun beating directly on it. It also does very well in low-ambient light. The LCD "gains up" when shooting in these low light conditions, which is very important when shooting night-scenes, indoor shots, etc.
The Carl Zeiss 3x optical zoom lens helps produces sharp images that are virtually free from any signs of chromatic aberration. At full wide angle there is a mild amount of barrel distortion, but not enough to cause any major distortion in your subjects. The 5-point auto focus system is very quick and thanks to the focus- assist lamp, we had very little problems focusing on subjects in low- light conditions. When using Macro mode, we found that the flash does an excellent job of "throttling down" to ensure that it does not overexpose macro subjects.
The shooting performance was impressive. Press the power button and it's ready to go in just under 2 seconds. Power up to first image captured was a fast 2.2 seconds. Shutter lag was a mere 1/10 of a second when pre- focused and 2/10 of a second including autofocus. In Normal record mode, the shot to shot time is about 1.5 seconds. The W1 allows users to choose between two burst modes (Burst, Multi Burst). The number of images you can capture when shooting in burst mode depends on the image size and quality settings. Burst mode captured 9 frames in about 6.5 seconds. It takes about 9 seconds for the W1 to process a full buffer and then you can continue shooting. Shooting in Multi Burst mode, with the interval set at 1/30, captured 16 images in less than a second. When using Multi Burst mode, the image size is locked at 1MP and all 16 images a recorded within a single animated frame. Switching between record and playback mode takes about a second. In playback you can go from picture to picture in less than a second. All of our test were done using a 256MB Memory Stick Pro card, with the image size/quality set at 2592x1944/Fine mode and the flash off. All times may vary depending on lighting conditions, camera setting, media, etc.
The overall image quality in 2592x1944/Fine mode is excellent, for the most part the default settings produce well saturated and properly exposed pictures. The user can control the saturation, contrast and sharpness so you can "dial in" just the right look for your images. I found that the automatic white balance did its job well and only under some very mixed lighting did I need to manually set the color temperature. I was pleased with our outdoor test shots. The images were sharp, well saturated, and there was very little noise in open blue sky areas. You can see this by taking a look at our Sample Photos page. When shooting indoors, you will have to work within the limited flash range. It works well for Portrait and small group photos, but does not have the power to light up large open rooms. I did notice a slight amount of redeye when the flash was set to auto, but this minute amount is acceptable. Some people seem to always have redeye, no matter what flash setting you are using.
Bottom line the Sony Cyber-shot DSC-W1 is an all around great camera. It makes a perfect choice for those wanting a compact, durable, and easy to use digicam. With it's all-metal body, you can be worry free when tossing it in your luggage while on vacation. The 5-megapixel images it yields have plenty of resolution to make photo- quality 8x10-inch prints from home or you're local digital photo lab. It offers various shooting modes, which makes it usable by any member of the family. With a suggested list price of $400, it makes a great choice for your holiday gift list.
P. S. 有趣的是CP5200的防紅眼功能是以機內圖像程式作軟體處理，把人眼出現的紅色現像，以黑色代替。
