K-5 vs D7000 ISO3200/6400 Noise Test

JohnBee · 10-29-2010, 10:15 PM

This was so interested, I thought I'd let the first half sink-in before delivering the rest

RAW NO NR/PP

Yes all from RAW.
And judging by the histogram, I'd say one stop

there's no way the D700 is all black at 6400, not even the D3s gives out perfect iso performance at that sensitivity.

I'm saving the best for last

D700 samples left blank intentionally.

Now that you posted the D700 I have to say that the K-5 looks a little bit worse...............but not bad at all!

Raybo · 10-30-2010, 12:07 AM

I didn't look at the histogram, expose to the right?

I see you have lots and lots of friends over at the DP Nikon forums John!

Notice the trend?

First they laughed when it was posted that the K-5 would enter FF territory.

Now that it seems possible...
NR is the big issue.

I think that's a close to a win as were ever going to see

' ... of course Pentax reached FF, they use NR...'

I'm getting more concerned as to the K5 metering. Is this metering/underexposure at higher ISOs incremental? Rather making using auto ISO a bit problematic for me ATM. Coming from the K20d I'm still getting used to having images with 4 digit ISOs.

There certainly is underexposure whith matrix metering(no doubt about that). Though I noticed when dgaies shot low light scenes using center weighted instead, that things looked very good(almost perfect) in most cases.

So I'm thinking this may be more of a metering thing than a an underexposure issue...
Either way, if it is a problem, I hope Pentax addresses it in firmware rather than leaving it the way it is.
