A few years back, I shot this small, 15mm coin with my 6mpx Nikon D70S and a Nikkor AF 60mm micro. Using the same lens model, I took a second shot with my 36mpx Nikon D810. Single light source for both. This first picture is with the 6mpx D70S ~1:1 @ 100% crop. At the time, I thought the picture was fairly sharp--applied sharpening in post-processing too. I used a fairly small aperture, f29, so diffraction may be softening the image some.   This shot was taken with the D810 and the same lens--but at f11, ~1:1 with Mup and EFCS enabled. Even when downsampled to approx. the D70S resolution, the sensor has captured a lot more detail from the lens. Despite the definition you see, the sharpness I applied here is pretty small. Tests I've done indicate the EFCS plays a large role here in capturing a sharp image.  Finally, a side-by side shot of the crown detail, again downsampled on the D810 image.  Edited by DVCollector

Both shots are nice, the newer camara captures more detail but it seems a bit grainy. In some ways I like the shot you took with the 6mpx camera.
Nice 1 Penni by the way.

Thanks Bob, and I think you're right--the image doesn't need sharpening at all. I also suspect some of the graininess of the D810 is due to the LED light--the surfaces would be better with more diffusion. So here's the same photo at 100% resolution, without any sharpening applied in camera or by software: Watch out--it's a huge image.   Edited by DVCollector

When shooting other coins in the future, I would stick to adjusting the sharpness using a program like GIMP or Photoshop. Edited by Canadian-Banknotes

Less sharpening & less graniness produces are realistic image IMO. What kind of light are you utilizing?

Interesting shots. Like you I also have a sony(Nikon uses sony sensors)  Of course my Sony A7r doesn't have an EFCS ( electronic front curtain shutter) but its the same sensor. But with the D810 costing US$1000.00 more than the A7r.....I don't see enough of a difference between what my camera can produce and what yours does to justify the extra US$1000.00. If the rumours prove true: I think early next year you may be kicking yourself for getting the Nikon. The rumour is Sony is bringing out a medium format 46MP to 50MP and the cost is rumoured to be very close to the Nikon D810 |

If the rumours prove true: I think early next year you may be kicking yourself for getting the Nikon. There were criteria other than price that led me to this decision. For starters, the larger D810 body is a perfect fit for my hands; it balances out hand-holding with some of my 1kg+ lenses very well. The A7R may have the same sensor, but the D810 has a different image processor and a slew of other features (such as dynamic AF modes) that are important to me. So no I won't be "kicking myself"--for reasons discussed already. But hey, enjoy that A7R! Edited by DVCollector
