Sony NEX-5N 16.1Mp APS-C compact system camera


re: ISO Test Images @ Felix

Its quite difficult to test.

Firstly, they could have kept the shutter speed at something more realistic. Something like 1/10th , a speed that people can hold so a bit more realistic for realworld use. Then they can change the apperture to control the light. This has some issues as it does effect the final picture due to depth of field differences but ultimately its another way of doing it.

The issue with measuring ISO quality though is you need to test in bright light and low light conditions.

I have a Canon 5D MII and a Canon 450d. As you would expect the 5D is much better picture all round. The difference though with high ISO ratings is marked dependent on the level of light. The 5D at 400 is absolutely perfect in good light conditions. The 450D not so. You really want to go down to 100. However, in low light conditions, even 5D can be a bit grainy at 400 (obviously nothing as bad as the 450D).
