645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII

Below is a real life resolution comparison. Purpose was to see how much real additional resolution the 645 provides compared to full frame or APS-C. Comparison is against K-5 and K10d with FA35mm, the Canon 5d MK2 with the 50mm L, and the Leica M9 with the 50mm Summilux. All shots at ISO 200, f5.6, 1/1000th. The 645d has a slightly unfair advantage as the 75mm lens is essentially a 60mm equivalent, whereas all the others are c. 50mm.

I resized the other files using BenVista photozoom so they match the 645d 100% crop.

Five examples below. Except for the 645d, I did not label them and erased the EXIF, so people can have some fun guessing.

To me it looks like something is seriously wrong with your comparison images. It might be just the upsampling iq? All I can see is very mushy pixels, one worse than the other. Is no3 in focus? I don´t think you doing any camera justice. It might be worse to show the original sized images, even if the size is a giveaway .
Anyway thanks for your effort.

Hummm, for a fair comparison, apertures should have been different, no? So they would all end up with the same DoF...

I'm always lost by those inter-format comparison, I never know how they should be done...

The upsampling by definition makes things mushier, but that is a real-life problem: if you want to print really large but your orginal doesn't have the resolution, you are forced to upsample at a certain point. There are different ways you can do this of course, but the S-spline algorithm used here will actually result in sharper pictures (as it tries to vectorise to some degree) than e.g. bicubic would.

Re focus, all images are in focus. However, some would have benefited from unsharp mask application after upsampling (e.g. no 3). I did not do this to keep the comparison like-for-like.

Re: 645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII

M9
5D
K5
K10

K10 is obvious to tell since you stated you used a S-Spline interpolation algorithm and it had the least resolution. IMHO, you should've just used a stepped interpretation algorithm.

Re: 645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII

I'm trying to learn about this digital stuff so, strictly as a learning exercise, here is what I thought:

1 has v. high resolution but some Moire and some noise, so, M9.

2 has high resolution, no Moire, an less noise, so Canon 5D

3 and 4 have lower resolution, with 4 having very obvious interpolation artifacts, so they are the APS-C cameras. I guess 3 is the higher-res K5 model, but I know nothing about Pentax DSLRs.

Re: 645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII

Its for fun right!

Thanks I do enjoy these things. I just sit here and pretend I am an expert LOL...

BTW no matter how perfect you made them some would complain. Then we come to the it's for fun! The cameras are each in their own class this is not to see who's better than who IMO...

It's easy!!! Yea... here goes easiest to hardest last.

OK first, have to say pic 1 is the 645D because its retaining far more detail than the rest.

EDIT OPPS should have read more careful, you state such!

Second, K-5 because it has a lot of CA/PF!

Third K10D, it has a moderate degree of CA and is OK.

Fourth, Leica M9; just guessing

Fifth, guessing its the 5d MK2

Re: 645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII

I greatly appreciate this effort. What the comparison tells me is that the 645D provides a vast improvement over all of the other cameras shown. This encourages me to think that th investment would be well worth the cost.

I wish other 645D owners would provide this kind of comparison.

your test vs that of IR: significantly different results...

Re: 645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII

I have no idea how 5d mkII, k10d and k5 (whatever they are) look like, but the second one really looks M9 to me.
The test is flawed in two respects, however:

1. In a real life situation, if I need a really large print, I will take a medium format camera.

2. When you need the very large print, you don't compare how the picture looks at 100% magnification on the screen, you set prints side by side and look at them. I found that M8 and M9 prints look much better than one may expect just by looking at the screen. To prevent any misunderstanding, I am talking 5 to 6 feet wide prints.

Interesting comparision, but I think to describe it as a 'real life' problem is a little bit misleading. It's really only an issue if you need to upsample, which in practice would mean print at A2 and larger. Below A2, and of course the limiting factor is the printer, not the sensor megapixels, so the differences would likely greatly diminish.

A more useful real-life comparison would be to compare the detail in the actual prints at A3 and A2. Bearing in mind of course that at normal viewing distances, it's the resolution of your eyes which become the limiting factor, even more so that that of the printer.
