Hello !
In your experience , how does it stand against the classic DSRL s at 1600 and especially 3200 ?

Answer greatly depends on which DSLR you compare the NEXes to. If I compare a NEX3 or NEX5 with my Nikon D3 at ISO 3200 the race is as interesting as watching two turtles run against a greyhound.

You can use http://www.dxomark.com to compare high ISO performance of different cameras. For instance here, I put the NEX3 and NEX5 against the D3s and the D3s has about 3-4 f-stops of advantage compared to the NEX.

Do you mean two stops ? Low-light ISO values (as defined by DxOMark) are approximately 800 and 3200 for the NEX 3/5 and the D3s respectively. The ratio. equal to four, corresponds to two stops.

Two or three probably is more close to truth yes, I browsed the comparison too casually.

Difference is significant, and would be best shown with real photos. The higher you crank native ISO (not software simulated) the bigger the differences would be. 3200 is on the upper scale, so expect difference larger than numbers would indicate.

I guess you will not be using NEX on those iso's. In my experience the result is quite tragic - ISO 800 is my upper limit.

S**t !!!!! Laughing I really need 1600 and don't mind at all 3200! Still , I have seen some samples from Sony (Yes, right it was a A 55 , OK !)that were blowing me away !
I am considering DSRLs in the APS-c gang , starting with my Canon EOS XTi / 400D (very happy with the 800 , usable 1600) , and going to the new generation of sensor/image processor of the EOS 550D, Nikon 90 ,Pentax K-x , Sony A 55
Another question : that famous twilight handheld shot mode works in Aperture priority with manual focus lenses ?

It depends a lot on what you consider to be acceptable quality. It should certainly give equal to or better 1600 and 3200 than the 400d.

Do you shoot raw or jpeg? jpegs tend to look cleaner because they have had noise reduction applied in camera already, raw tells a different story! I would say the nex cameras are as good as current slr's such as 600d

I tend not to trust dxomark too much, it sometimes seems to contradict events in real life such as ranking large sensor digital backs lower than DSLR's for colour depth etc even at low iso settings.

ISO 3200 on the Nex is equivalent to the latest crop sensor Canons in my experience, which ain't bad!

Would it be just "too polite" to cite their site/copyright if you do copy from them?? Or just not your style...? Wink
