My d610 just went in for repair, and while it was gone I borrowed a friend's d750.  I was AMAZED at the difference in sharpness of my photos using the same exact lens.  I have always been told that the glass makes the difference, but it was striking to me.  I did not calibrate my 50 on the d750 either, I just stuck it on and went with it.  So now I'm contemplating purchasing the 750.  My question is....why would the 750 be so much sharper?  Has anyone else worked with both and experienced this difference?  

 

I want to make sure it wasn't just a flook before spending the extra on the 750 when my 610 is almost brand new.

There are two factors in the D750's favour when it comes to sharpness SOOC. The new signal processor converts the analog signal from the sensor differently, so the result is crisper and the AF system is very much superior.

I don't own either body, but I have held several workshops where the participants have had either of them. I don't know if it is sharpness or clarity that is better in the D750, but there is quite a difference in the end results. You can make a picture control for the D610 to get at least as crisp, if not crisper results than the D750, but it takes some experimentation so you don't overcook it and get oversharpened files that are more difficult to work with.

Thank you for the feedback Nikonian.  I could not quite understand how the quality was so drastically different, whether that be the clarity or sharpness.  It seems worth the extra to get the 750 if those are going to be my results.  I just hope I can recreate the work when my new one arrives that I already experienced with my friend's camera.

Did you get a D750 and, if so, was it as good as you'd hoped?

I've noticed a slight difference in sharpness between my D610 and D7100. They both have 24mp on the sensors. The 7100 with the smaller sensor, but same number of pixels, is a wee bit sharper.

 

I assumed it was the smaller sized pixels crammed into a smaller sensor that makes the difference.

Sharpness or perceived sharpness seems to be a bit of a weird thing! If I look at the images on 500px, which seems to have, technically, better quality pics than any of the other similar sites (let's ignore that statement for the moment, people! :D (I just added 'technically')) I can immediately spot pics taken on D800/810s. More pixels in the same space as the D610. They're not uploaded at full resolution so how can this be?

 

I am truly puzzled by it… Am I confusing sharpness and resolution? Will good 'sharpness' show up better on a high resolution sensor even if the image isn't viewed at full resolution? I would really like to know the answer to this!

My pics NEVER seem that sharp. I'm not an idiot and I have thirty-odd years of experience, clearly I'm missing something...

The strength of the Anti-Aliasing filter and thickness of the filter stack over the sensor makes a big difference in how sharp an image appears. I believe the 24MPixel D-format sensors do not use an AA filter?

 

An AA filter is a low-pass filter, meaning it "blurs" the image. My 18MPixel Monochrome camera, no AA filter, no Mosaic filter, 0.8mm filter-stack: sharp.

I've had the D7100 and I think it may be sharper the my D750. Can't compare because I sold the D7100. The D7100 does not have a low pass filter and that may be why its images are sharper.

I've never seen that much difference in sharpness because of rhe body. I have shot 5d en 1d canons before moving to nikon. Shooting a d700 and 750. At low iso i do not see a difference in sharpness at low iso. There is a difference in the amount of detail they can produce. But even that difference of detail is hard to spot in print under a3 size.
