What is the difference between Sony DSC W290 and T900, and why is the price about the same!

Personal suggestions and opinions for your reference: Sony T900 is a card player with a periscope lens, and the imaging effect is slightly lower than that of the Sony W290 card player with a telescopic lens. Sony T900, Sony W290 is a fully automatic camera, for a variety of complex and changeable shooting environments, can not be manually adjusted aperture, shutter and other parameters to obtain accurate **, but can cope with a variety of complex and changeable shooting environments through various shooting modes pre-made in the machine, but in the case of poor light, especially when shooting night scenes, the imaging effect will not be ideal, but the general home is fully competent.

Pay attention to the appearance, Sony T900 is more delicate and stylish. (On the Sony T900, the 920,000-pixel inch touchscreen as the biggest buying point is only the difference between eye-catching and unattractive when reviewing the photos taken, and it has no effect on the actual imaging effect, and the large-size display will consume more limited power.) Sony T900 and Sony T series old models, Sony W290 and Sony W series old models, the main imaging device sensor chip CCD size is almost the same, are about 1 inch, although some have millions of pixels to improve, the actual imaging effect does not have any major substantive differences, basically the same type, the same grade model, belongs to the new bottle of old wine, without any outstanding functions, only some more fancy functions that have no impact on the improvement of the imaging effect, because it has just been launched, ** is high, At present, the cost performance is low.

From the perspective of imaging effect, the Sony T900 is the same as the old Sony T series models, and it has not been improved, which is not ideal. If you choose 1 out of 2, Sony W290 is better. (SonyW290The biggest buying point is that there is a 28mm wide angle, on a household consumer-grade DC camera, don't care too much about the presence or absence of a wide angle, with a wide angle, the actual imaging effect is by no means as good as imagined, without a wide angle, the actual imaging effect is by no means as bad as imagined.)

Sony T900, Sony W290 price, you might as well pay attention to Sony W300, Canon IXUS980IS, better performance, worthy of Sony W series, Canon IXUS series in the flagship model, ** around 2300 yuan, the main advantage is that the size of the sensor chip CCD is relatively large, about 1 inch, (Sony T900, Sony W290 is only 1 inch), the large size of the sensor chip with more than 10 million high pixels, It can really bring higher quality imaging effects, in addition to a variety of pre-shot modes in the camera, it also has a comprehensive manual shooting function, you can integrate more into the effect you want when shooting, and the fun and space of shooting will be greater, especially when shooting pure night photos, after manually adjusting **, aperture, ISO and other parameters, the photo picture effect obtained is clear and clean without any noise, it is Sony T900, Sony W290 with a so-called program mode similar to night mode (commonly known as fool mode) The imaging effect captured by the camera cannot be compared. Buying a camera is the same as buying a computer, what suits you is the best, you can compare them according to your own price and preferences, and check the information on the Internet.

Poor imaging of t-series periscope lenses.

Sony W290

12.1 million pixels.

Image sensor size: 1 inch.

Optical zoom 5x.

Equivalent to 35mm focal length 28-140 about 1900 yuan.

The selection of the camera should be based on the size of the image sensor, lens style, quality, optical zoom range, aperture, ISO, whether there is a manual function, the pixel of the sensor and other comprehensive considerations, try to choose a large CCD, periscope lens imaging poor.

The true size of the 1-inch CCD is. Entry-level SLR sensor size:

mm, full-width SLR sensor size:

The high pixel of mm does not mean that the image is good, and the sensor size is not increased only to increase the pixels, and the overload of the sensor loses the accuracy of mold dust, and it is easy to appear small spots or strange colors when the light is poor.

Fashion choice Sony, photography choice Nikon, Canon, Sony video camera is very good, the camera is average, low cost performance.

The card machine is more than 1500 is luxurious, and the fiber training is less than 5 times the light change is low-end.

AA is convenient and cheap, use 2 and 2 other 2 standby, 4 charging AA is only more than 100, in case there is no power just 2 AA, lithium is expensive, in case there is no power and no play, it is recommended that Supermaster and Nanfu high-capacity rechargeable batteries.

The screen of the T90 is already very good as the mainstream configuration of digital camera screens, and even in terms of body size.

The T900 is also thinner and lighter, making it more portable.

An upgrade to the T70 from Sony.

T90 is actually.

The economic version of the T900 is Sony.

The T90 is a card machine with a periscope lens.

The imaging effect is better than that of those that use telescopic lenses, such as Sony.

The W series hall imitation card machine should be slightly bottom.

Hello! Comparison of the main performance of the two machines: 1. Effective pixels (no substantial difference) W300 13.6 million pixelsSony TX9C12.2 million pixels with more than 10 million pixels can already output more than A3 format (general calendar size)**,It's enough to meet the needs of home shooting,W300 is higher than Sony TX9C's 1.4 million pixels are not much practical。

As long as the maximum output format is reached, the height of the pixel has little impact on the imaging clarity, but only has a decisive effect on the size of the output **. Therefore, in terms of performance, the two machines should be regarded as "no substantial differences". 2. Image sensor (no substantial difference) W300 configuration [1-inch Superhad CCD] The 1-inch Superhad CCD is basically the largest specification in the configuration of the image sensor of consumer digital cameras.

The CCD has a large area and receives more light information, which is much more natural and clear. Sony TX9C Equipped with [1-inch back-illuminated CMOS, Exmor R CMOS] The back-illuminated CMOS has the following advantages:

1: It has a higher latitude (it can be understood that the highlights are not easy to spill, and the low light is not easy to underexpose).

3: It has better low-light imaging capabilities (the imaging performance at high sensitivity is much better than that of traditional products), so the back-illuminated CMOS is now enough to be regarded as synonymous with "high image quality".

The Sony TX9C is a digital camera equipped with a "back-illuminated CMOS". In view of the above factors, the imaging effect of the two camera sensors can be regarded as "equal". 3. Lens (Sony TX9C leading) W300 configuration [35-105mm telescopic Carl Zeiss lens] without wide-angle function.

The Sony TX9C is equipped with a 25-100mm periscope Carl Zeiss lens with a wide angle of view and a 25mm wide angle. Of course, the Sony TX9C's 25mm wide-angle lens is more practical. 4. LCD screen (Sony TX9C leading) W300 configuration [inch 230,000 pixel LCD screen] Sony TX9C configuration [inch 10,000 pixel touch screen] The LCD screen display effect is delicate and clear, and it is currently the top specification of the most digital camera.

5、Cost performance (Sony TX9C is slightly ahead)W300 At present**about 2300 yuanSony TX9C current**is about 2400 yuan100 yuan or so, Sony TX9C has obtained"wide-angle function、Top LCD screen",It belongs to"Value for money。 6. Handling (W300 leading) W300 comes with a "partial manual" function. The Sony TX9C is fully automatic.

Buying suggestion: The imaging effect of the two cameras is comparable, but the difference lies in appearance, LCD screen, wide-angle shooting and handling. If you talk about the price ratio, of course, you should choose Sony TX9C.

If you pay attention to the "playability" of the machine, you should choose the W300.

The Sony T700 is good, and I'm going to be able to lean towards the T700
