Nikon D7100 vs Panasonic gh2 sharpness

So I have a little time now and been investigating a bit more the video capability of my newly acquired D7100 (Nikon photo shooter) vs my Panasonic gh2. I made a series at different sharpness setting in camera, I will upload them a little latter when I have finish uploading some work. Meanwhile lets do a little blind test, because I was surprised how close they looked. I use the same Tamron 17-50 at 50mm on both of them.

I put this link in case DVXUSER resize the images

So no one has a clue :) I tried to match them, in fact I color corrected the Nikon (not sharpness) one and so it might have degraded the image a bit. So don't look too mutch at the exposure or the latitude of the scene
 
Sorry. You are not supposed to in any manner tamper with any image in a side-by-side test. You wasted your time.
 
Daniel,

I Say No.1 "GH2" and No.2 "D7100". I believe the second photo is the Nikon D7100 because of the slightly shallower depth of field and for the compression between the foreground and background.

I think it's a great test and far from a waste of time. The point being that the image quality gain with the new Nikon sensors, while great on paper, makes very little or no difference for 1080 web distribution. I think the GH2 image (sharp 2.png) is sharper than the D7100 image (sharp 1.png).

In the end of the day my new G6 is a much better handling camera with all it's feature for video than my T3i with Magic Lantern, which is orders of magnitude easier to handle than a D7100. Story, light, composition and editing are so much more important than the tiny difference in sensor performance, that I'll take the convenience the G6 or even a Gh2 any day over the D7100.

If you count stills it completely changes the equation though :)

Cheers,
Pete
 
I think #2 looks sharper and has a slightly longer focal length, but #1 has more latitude. So my guess is #1i s D7100, #2 is GH2.

I will put the original files on-line shortly. The aim of this test is just sharpness, I did not in anyway sharpen the d7100 image. I just put them closer in terms of contrast and colour because they can play a big role in the sense of sharpness. I worked on the D7100 file because I did not want anyone to think that I was bias toward the D7100.
 
I think sharp 1 is D7100. Better DR and when I look the dog I think I see the quality of this toshiba sensor to render on the same picture perfect saturated colors and pastel hues (dog's red tie and dog's hair)
 
"I just put them closer in terms of contrast and colour because they can play a big role in the sense of sharpness."
exactly my point. Spend some time at DPReview.com and understand that my buddy Phil could never have accomplished anything if he in any manner manipulated any part of his test images.
Side by side is just that. An exact unmanipulated comparison.

You won the chance to know perhaps a hidden gem. Perhaps the best image quality of a large sensor camera below $ 3000. Imagine a alias/moire free, Cine 35 mm, 11-12 stop of DR camera with very good low light... with about the same resolution than the gh2, which itself has compared favourably with high-end cinema camera in many test for $ 1200.

As I told you I tried to match the two images (without sharpening) so that other factors like contrast does not interfere in the sense of resolution. I will post the unmodified version latter. But for now people can concentrate on only one aspect I wanted to test.
 
Again to all, this is a sharpness test, so don't look at the DR etc. I had to up the contrast etc of the D7100 image to match both of them. So just judge sharpness and detail to make a conclusion.

d7100? it does have moire though. since the OLPF was removed in favor of more sharpness (versus D5200), moire can pop up in certain situations again, probably a lot less of a worry than other comparable dslr. this is all according to what i've read, but i believe it's not accurate to say no moire on the d7100.

Moire on the D7100 is neglegible, banding noise is more of a concern but can be greatly reduced using tonalizer or, I guess, neat video. Especially if you record to an external device in pro res 4:2:2

I have yet to find a situation where my D7100 has shown Moire. FPN(Fixed Pattern Noise) is the only problem I have noticed with my d7100, however, I am learning ways to reduce or minimize that.

Every camera can show moire. I even had moire once on my d800 36 megapixel still. What has happen is that with the advent of the 5d2 and dslr line skipping, it has become a problem and we have focused on that. Now I have never seen until now any moire on my D7100, it could happen, but it will be an exceptional rather than a minimal issue.
