One more preference of DSLR: low noise

And one more preference of SLR camera – this device can take pictures without noise. All of previous Digital SLR cameras from Canon and Nikon as: Canon EOS 300D, Nikon D50 and D70s has smaller than modern models sensor size (6, 3 mega pixels). Look at The summary table of the most interesting 6-7-8 megapixel DSLR camera specifications; But what as perfect pictures it was taking! And how much money it was worth! There was nothing (just a little) about noise. Instead now we have as a general rule ten mega pixels not expencive devices as: Canon EOS 400D (Canon Digital Rebel Xti), Nikon D80 and Sony A100, Pentax K10D and Samsung GX10 from new Digital SLR camera manufacturers. It costs less than $1000. It makes accessible to take high-quality pictures for beginners. For comparison I made a summary table of the most interesting 10-megapixel DSLR camera specifications. I know that it’s useful for people who are choosing their first SLR camera. But later I will make a summary table of 9/10-megapixel Compact cameras. In fact there are so many new attractive Compacts. And they have such cool opportunities.
Sony A100: what about image noise?
There are two kinds of noise: sensor noise and noise in digital images. Why compact cameras generate more noise then digital SLR’s? Because the sensor in compact cameras makes more – it’s used when you are focusing and it’s used when you take a shot. It’s get heat up and noise increases with temperature. And SLR’s cameras are made with higher quality components and more powerful processors than compacts. But it’s not the rule – because for example: Olympus SLR’s sensor have got more noise, that some Sony’s compacts. The noise is not a problem for many compact cameras users, if you don’t need to make posters. It’s probably to see the noise in digital images if you use an ordinary LCD monitor. But I have the Mitsubishi Diamond Pro and can see anything I need. There are many new LCD devises with grate resolution and not grate prices in modern markets. May be its more interesting to use the digital SLR camera today?
A propos, You can use lower ISO settings on your DSLR for getting the lowest noise. The majority of digital cameras work best at ISO100 and you can use this setting and a tripod for best results. You don't want to take a great image only to find the noise unacceptable, especially if you want to try and sell your images or to publish it.
