645D ISO / Lens Tests (All Full Size Samples)

See:-

(in Japanese)

I think this time these samples look better. Colours and sharpness are better. And the 3d feel is exceptional. Sometimes I just wonder why those Pentax official samples do suck, and as usually!? ^:-0

the new 55mm lens is quite a beast.. even i jpeg.. wonder what could come out of raw...
I saw low noise at ISO800/1000 even without NR. As for new DFA55 - very good IMO.
Old FA33-45/4.5 is good too. Even at f/4.5.
Rice...What are you so quick with conclusions? :) Official samples just show us the work of in-camera RAW convertor with various settings.
Nothing else. And this samples are not bad for JPEG. Anyway, non-official samples are better. Paradox? No.

All serious amateurs and professional know how to work with RAW files and how to tweak JPEG for own needs...
Nothing to complain of official samples.

What "conclusions"? I just commented on the samples!
These conclusions:
"IF the IQ of the 645D is just like this, why Pentax/Hoya needed to waste the time and resources to put out such crap? And at that price tag, who would buy such a crap (possibly..)? Frankly, they should concentrate to make a Full Frame K-mount DSLR instead. Or, even just to make an EVIL first, in order to secure their market position and share! :-( " http://ricehigh.blogspot.com/2010/05/official-645...

Yes, you put an 'If' at the beggining, but then a whole highly negative paragraph ('such crap') based on the first official samples. I would call this 'quick conclusions'.

But this is no new on you at all, we should be used to...
I have not to say every sample out of the 645D is good, have I?
Rice, what do you think about 645D's noise.? It's really very low even with NR OFF...ISO800/1000 are not worse than 135 system. But 645D has 39.5 MP picture, not 21 or 24 MP.
I think it's mix of new Kodak sensor + PRIME II.

I haven't measurbated into those higher ISO samples for more. But my initial impression is that it is just a bit noiser than other pics from other DSLRs with the same pixel size, e.g., the D3X.

For more sensor pixel size comparisons, you can read this:- http://ricehigh.blogspot.com/2010/03/comparison-o...
ISO800 of D3X is not better. And ISO1600 too.
