And yet another stupid comparison … but sometimes it's just fun.
It doesn't deserve an own thread so I thought I'll just add it here. I hope Chris don't mind.
P45 on Contax 645, Zeiss CZ Planar 2.0/80 @ f8, ISO50, 1/60'', 39MP
versus
Sony A7R, Zeiss ZM Planar 2.0/50 @ f8, ISO50, 1/60'', 36MP
Actually I've tested some things with my 55mm lens on the Contax in the backyard. Since the tripod was in place I thought why not quickly compare the Contax/P45 and the A7R?!
This is why the position of the tripod remained the same. However, coincidentally the lenses cover almost the same height of the scene. Horizontally A7R shows a wider part of the scene (naturally). So the magnification of the scene is somewhat larger on the P45 and this is why the comparison is a bit in favour for the P45.
Also, the ZM Planar 50 is a bit sharper at f5.6 on the A7R while the Contax 2.0/80 shows about the same crispness at f5.6 and f8 on the P45.
Too, there are certainly better lenses for the A7R - but on a tech cam with digital large format lenses also the P45 would look better. So lens wise I think the test is pretty fair.
Then again: who cares :-) This isn't for science ...
Sorry - the scene is totally boring! (But it's great to check the registration of my split screen… so…)
Enough said… here it is (P45 on the left, A7R on the right in all screenshots).
Have fun!

100% crop from the right edge:
Shadow detail … these crops come from the corner on the bottom right.
I've pushed exposure on both shots by 4 stops in C1.
100% crop, +4EV, without NR applied:
100% crop, +4EV, with NR applied on the P45 (in addition some slight color adjustment):
I am really amazed how well the little A7R performs with an adapted ZM lens (not particularly in this test... but in general). And the camera will certainly have a place in my kit (mainly for stitching, though).
I am also amazed how well the 8 years old sensor of the P45 compares to the latest and greatest 35mm sensor in this comparison (however, in low light, especially tungsten, things will look worse).
