Imaging Resource的Sony W-5 review推出了：

The Imaging Resource
Quick Review
Sony DSC-W5 Digital Camera

Color: Good overall color. A tendency toward slightly warm color casts, but accurate hue. Pretty good performance under incandescent lighting, but still a bit warmer than I'd prefer. The DSC-W5 often produced slightly warm color in my testing, but its color was quite good overall, and its hue accuracy was better than that of most digital cameras I test. Skin tones were pretty good, but the blue flowers of the bouquet in both the indoor and outdoor portraits were a bit dark. The camera's Auto white balance setting typically did the best job, though the Incandescent setting handled the Indoor Portrait (no flash) best. All in all, a good performance.

Exposure: Generally accurate exposure, but high contrast. The DSC-W5 handled my test lighting quite well, though the camera's high contrast led to lost highlight detail under the high-key lighting of the "Sunlit" Portrait. Its contrast adjustment worked well, but produced odd color-saturation problems in Marti's skin tones, so I wouldn't recommend its use for shots with people in them. Indoors, the camera required higher than average positive exposure compensation, and the standard flash exposure was rather dim. The DSC-W5 had no trouble distinguishing the subtle pastel tones on the Q60 target of the Davebox. Good results overall.

Resolution/Sharpness: High resolution, 1,350 lines of "strong detail." The DSC-W5 performed about average on the "laboratory" resolution test chart for its 5.0-megapixel class. It didn't start showing artifacts in the test patterns until resolutions as low as 1,100 lines per picture height vertically and horizontally. I found "strong detail" out to at least 1,350 lines. "Extinction" of the target patterns didn't occur until about 1,700 lines.

Image Noise: Good noise levels, but some sacrifice of subtle detail to achieve them. The Sony DSC-W5 did a good job of holding image noise in check as the ISO (light sensitivity) was increased, but it did so by trading away subject detail in areas of subtle contrast. This means that shots at ISO 400 were rather soft-looking (although probably acceptable to many users) when printed at 8x10 inches, but looked fine at sizes of 5x7 and below.

Closeups: A small macro area with pretty good detail, though details were a bit soft throughout the frame, and even softer in the corners. Flash had trouble up close. The DSC-W5 captured an average macro area, measuring 2.31 x 1.74 inches (59 x 44 millimeters). Resolution is high, but details were soft throughout the frame, with increased softness in the corners. The W5's flash didn't throttle down enough for the macro area, and overexposed the frame. (Plan on using external lighting for your macro shots.)

Night Shots: Very good low-light performance, with pretty good noise and color. The Sony DSC-W5 is an excellent low-light shooter, able to deliver well-exposed shots to the limit of our test (1/16 foot-candle, about 1/16 the brightness of typical city night scenes), at any ISO setting. Its autofocus system worked down to about 1/4 foot-candle with the AF assist light turned off, and in total darkness on nearby objects with the AF assist enabled. Noise levels were quite low, although some subtle subject detail was traded away, particularly at the highest ISO setting. All in all though, a good choice for after-dark available-light photography. (Note though, that its flash tends to underexpose a fair bit, so it's better suited for available-light shooting than for flash photography.)

Viewfinder Accuracy: A pretty accurate LCD monitor, but a tight optical viewfinder. The DSC-W5's optical viewfinder was a little tight, showing only 85 percent frame accuracy at wide angle, and about 82 percent at telephoto. The LCD monitor proved more accurate, showing just slightly more of the subject than appeared in the final image.

Optical Distortion: Higher than average barrel distortion at wide angle, though low pincushion. Some softness in the corners, but not extending too far into the images, and fairly low chromatic aberration. I measured approximately 0.9 percent barrel distortion at wide angle, and about 0.08 percent pincushion distortion at telephoto. Chromatic aberration was low at wide-angle lens settings, and lower still at telephoto. (This distortion is visible as a very slight colored fringe around the objects at the edges of the field of view on the resolution target.) There is some softening in the corners of the frame at wide angle, less at telephoto, but in neither case does the softness extend very far into the frame.

Shutter Lag and Cycle Times: Great speed, very responsive. The Sony DSC-W5 is faster than average starting up and shutting down, and when it was running, it was faster yet. Full-autofocus shutter lag was a good bit faster than average, at only 0.31 - 0.62 second. (Average these days is a range from 0.8 - 1.0 second.) When the camera was "prefocused" by half-pressing and holding down the shutter button before the shot itself, shutter lag dropped to an astonishing 0.011 second. Shot to shot cycle time was also very fast, at only 0.95 second for large/fine JPEG images. In continuous mode, the camera could capture up to 9 large/fine images at a time, one every 0.70 second. (1.43 frames/second.) Bottom line, the Sony DSC-S90 should be an excellent camera for keeping up with an active family or capturing shots of sporting events.

Battery Life: Excellent battery life. The Sony DSC-W5 uses a two AA batteries for power, and two Sony-branded 2100 mAh NiMH batteries are included with the camera. Unfortunately, the camera uses a "dummy battery" AC adapter (rather than a standard external power connector), so I couldn't conduct my usual direct measurements of power consumption. For what it's worth though, Sony claims that the W5 will run for as much as 190 minutes in capture mode with the LCD display turned on, capturing up to 380 full-resolution images. If true (and I have no reason to disbelieve it), the DSC-W5's battery life is very good, especially for a camera powered by only two AA cells. While the camera comes with two good-quality NiMH AA cells and a charger, I do recommend that you pick up another pair or two of high-capacity NiMH batteries. See my battery shootout page for a current listing of the top batteries, tested under actual load conditions.

Print Quality: Good prints at 11x14 inches, sharper at 8x10. High-ISO shots best only at smaller print sizes. Testing hundreds of digital cameras, we've found that you can only tell just so much about a camera's image quality by viewing its images on-screen. Ultimately, there's no substitute for printing a lot of images and examining them closely. For this reason, we now routinely print sample images from the cameras we test on our Canon i9900 studio printer, and on the Canon iP5000 here in the office. (See our Canon i9900 review for details on that model.) Prints from the Sony DSC-W5 looked good as large as 11x14 inches, although they were sharper-looking at 8x10. The tougher test was with high ISO images, and here the W5 was a little weaker. Shots captured at ISO 200 were marginal at 8x10, looking much better at 5x7, and those shot at ISO 400 were really only usable at sizes of 5x7 and smaller. (Although a lot of that will depend on the subject matter: Subjects with lots of contrasty detail will fare much better than ones with large areas of more subtle contrast, such as people's hair, grass, etc.)

Conclusion

Pro:

Very fast, excellent shutter response, excellent shot to shot speed
Fast startup/shutdown time
Better than average color accuracy
Very capable movie mode
Very fast multi-burst mode, great for analyzing golf/tennis swings
Large 2.5" LCD display
LCD is usable in very bright light
Excellent low-light shooting capabilities
Unusually bright AF-assist light
Design is compact but usable, fits the hand well
Very good battery life

Con:

So-so handling of household incandescent lighting
Autofocus tended to focus on objects in front of the main subject more often than I'd like/expect
Rather contrasty default tone curve
Low-contrast option causes strange saturation loss in certain flesh tones
Anti-noise processing trades away a fair bit of subtle subject detail to hold the noise in check

As the lower-resolution sibling of the DSC-W7, which we also reviewed recently, the Sony DSC-W5 offers all the same features, but with a 5.1 megapixel CCD (vs 7.0) and at a list price that's $100 lower. As such, I'm a bit more enthusiastic about it than the more expensive W7, feeling that some of its minor shortcomings are easier to accept at the lower price point. Like the W7, the Sony W5 provides more manual exposure control than most compact models permit, yet is easy to use in full-auto mode, and its seven preprogrammed scene modes help with tricky subjects. The large 2.5-inch color LCD monitor is excellent for framing and reviewing shots, and the overall design and layout of the W5 is user-friendly and hassle-free. If you're looking for a good "take anywhere" camera with great versatility and excellent color and tonality, the Sony DSC-W5 deserves a close look, and for $100 less than the W7, it's a relative bargain.

To sam1989朋友：

「選擇快門有冇特別技巧，一般如何考慮設定時間...
過久又會有甚麼效果..」

一般來說，我們選擇快間時需要觀察相機畫面自行計算出來的EV值，設定快門時間後我們可以即時看到EV值的變化，數值並不一定是「零」為之最好，很多時候我們須了解拍攝影物的光暗及顏色分佈情況，第二要考慮的要點是，我們是以那一種的測光模式去拍攝呢？那才去決定EV的加減，對拍攝出來的相片曝光正確及表現有很大的影響。過久當然會有畫面部份出現「爆光」及畫中細節盡失的情況出現。可是，數碼相機最方便的是：多拍數張不同曝光值的相片，那不就OK嗎？！

[sam1989]

TO:zeusho兄：

EV值是否在相機對焦測光時會顯示出來，
還是設定快門後顯示....
這方面真的有點搞不清...

或許我是購機後再向你討教...

THANK YOU!

zeusho，我先排買既W5去長洲影漂色時唔見左，原本想買返一部，但好似唔抵，唯有直接買V3。由於V3有夜視功能，所以我想買枝紅外線燈。SONY原廠都有一枝，但又冇寫support V3，打上HOTLINE問又話唔得，但PRO SHOP又話得，但PRO SHOP咁光拎黎試下都冇用。所以想問一問你有冇朋友試過，同埋用鴨寮街D紅外線燈又得唔得?因為原廠$400 cover 5m，鴨記$120 cover 50m，只係鴨記既唔靚仔同要用L架及自駁電源。

另外可唔可以教我點貼相?我都想試下貼。如果有時間睇下我相簿俾下意見。

To sam1989朋友：

EV值基本上在任何時候都會顯示，當你設定快門值時當然亦會有即時的變化了…

To hpsimon朋友：

印象當中我好像在以往的交流區見過你？回到公司有空回應你的問題，要離開了，再見…

[zeusho]

To hpsimon朋友：

Sony原廠紅外線燈 (HVL-IRM)是支援Sony V-3的：

http://www.ecat.sony.co.jp/cs/acce/acce.cfm?pd=18698

http://www.ecat.sony.co.jp/cs/acce/accessory.cfm?PD=2269&KM=HVL-IRM

它能拍攝到3M至20M的距離，所以可以放心使用，非原廠的我則不提議購買，我本身及朋友都沒有試用過…原裝的亦要使用L架及需自行供電。

至於貼相的方法大家可以跟以下的的方法：

[img src="http://www.abc.jpg" width=260 height=390]

之後請把[及]轉成<及>，後邊的width及height是設定相片的長度及高度；
另外，希望大家不要在本區進行試貼，在貼相前請大家到
DCFever 討論區主頁 -> 公開討論區
試貼成功後才回到我們的交流區貼相，相片請不要設定太大，影響大家觀看交流區。

P. S. 相片是直相：width=260 height=390；橫相：width=390 height=260，希望大家只貼出用心拍攝的相片，盡力不要隨便亂貼一些隨便拍攝的作品，因為本人及很多朋友都希望有更多W系的出色作品令我們的交流區更加出色…謝謝！

zeusho，我有時都會上黎吹下水同搭訕，我記得上次同你傾過有關F828既話題。唔該晒你俾我既資料，其實原裝支燈可以直接用HOT-SHOE (即係外置閃光燈既位)，但價錢真係貴，星際間SONY都要$360但無貨。

至於POST相，我發覺我只係得D用828影既相可以POST下，W1/ W5就偏重於SNAP-SHOT同工作上用。不如我俾大家睇下828影出黎既效果。

以下為Sony W-7的Reviews：

DC Resources
The Sony Cyber-shot DSC-W7 is a very capable 7.2 Megapixel camera. It offers very good image quality, robust performance, limited manual controls, support for conversion lenses, excellent battery life, and a nice movie mode.
The DSC-W7 is a fairly compact camera that probably won't fit in your back pocket, but it's still small enough to take just about anywhere. The body is made almost entirely of metal, and it feels very solid. The controls are well-placed and it's easy to operate. The W7 has a redesigned 2.5" LCD display that's both easy to see in bright outdoor light as well as dimly lit rooms.
Camera performance is excellent, with a super-fast startup time of just one second, fast focusing times and no shutter lag. The one area in which the W7 lags a bit is in the continuous shooting department. Battery life was well above average, especially if you use high power NiMH rechargeables.
Photo quality is very good for the most part, with saturated and accurate colors and reasonable noise and purple fringing levels. Images were a little soft at times, though that's a pretty subjective observation. In addition, the night shot was a little soft and noisy, and there was more purple fringing than I would've liked to see.
The W7 has a decent selection of features as well. It has full manual control over shutter speed and limited control over aperture and focus. I would like to see less restricted control over aperture, and while Sony's at it, how about a custom white balance feature? The W7 has quite a few scene modes plus a fully automatic mode for those seeking simplicity. The camera's movie mode is excellent, though do remember that you'll need a Memory Stick Pro card in order to take advantage of it.
I have a few other complaints before I end this review. The included 32MB of built-in memory is somewhat of a joke -- you must factor the cost of a Memory Stick into the purchase price of the camera! Second, with the exception of that Cyber-shot Life tutorial, the bundled software is pretty bad. And finally, you cannot swap memory cards while the camera is on a tripod.
Overall the W7 gets the thumbs up from this reviewer.

What I liked:

Very good photo quality (though see issues below)
Fairly compact metal body
Huge 2.5" LCD is usable in bright outdoor light and in low light too
Robust performance
AF-assist lamp; good low light focusing
Excellent movie mode
Support for conversion lenses and filters
Great battery life; rechargeable batteries included
Live histogram in record mode
USB 2.0 High Speed supported

What I didn't care for:

Images a bit soft; some corner blurriness
Redeye
Disappointing burst mode
32MB of built-in memory is way too little; Memory Sticks cost more than other card formats
Except for the tutorial, bundled software is lousy
Can't swap memory cards while camera is on a tripod

The Sony DSC-W7 is a nearly identical follow-on to the preceding (and extremely popular) DSC-W1 model, the main differences being a larger 7.2-megapixel CCD, 32 megabytes of internal memory, and a couple of extra exposure options. Like the W1, the Sony W7 provides more manual exposure control than most compact models permit, yet is easy to use in full-auto mode, and its seven preprogrammed scene modes help with tricky subjects. The large 2.5-inch color LCD monitor is excellent for framing and reviewing shots, and the overall design and layout of the W7 is user-friendly and hassle-free. If you're looking for a great "take anywhere" camera with great versatility and excellent color and tonality, the Sony DSC-W7 deserves strong consideration.
