I have been seeing how far I can push my new camera setup to capture fine details on die varieties. I'm pretty happy at how my camera captured the multiple MPDs in the denticles with a minimum amount of noise and aberration--they're obvious even without arrows. That's a big die crack through the date too.  I shot this with my Nikon D810 using the 105mm micro f2.8 (VR off of course). Shot mirror up, EFCS enabled, 1:1 magnification, f11, 1/100s, ISO 200, "flat" picture control . Scaled down slightly from 100% crop. One Jansjo light at low angle brought out the MPD details pretty well. This color is true to this particular coin.  Compare to the same coin shot with my Nikon AW110. It's an underwater camera that takes OK macro shots. Obviously, there's more noise and chromatic aberration.  Edited by DVCollector

Well done.
My micro lens is a Nikkor 60mm so you have a significant edge on me with your 105mm.

Thanks Kanga--I have the 60mm too (the older AF type), but I don't usually use it for coin shots. Given the low lighting angle on this one, I might have a chance shooting this one on the 60. Just to compare the differences, I'll post a picture later today. |

Here's the same coin shot with my 60mm micro (first-gen AF model). EFCS enabled, 1:1 magnification, f11, 1/40, ISO 200, RAW 12-bit What do you think? Overall, I think the shot is a bit cleaner, with less distracting from the MPDs. The lens works great in this case, but it might get in the way of lighting on other shots.  Again, the same shot using my 105. Edited by DVCollector

Here's another shot of a tiny silver coin, a 1901/1891 overdate from Peru. Shot with the 60mm, f13, 1/80, Mup w/ EFCS, ISO 125. In this case, the D810's flat picture control really helped control the highlights.  Compare to this shot using the 105 and a different lighting setup and focus-stacking because it was an angled shot. Every shot is a lighting experiment.  Edited by DVCollector

That D810 is producing some nice images. The 60mm Micro is probably a bit sharper than you're showing as its optimum aperture is bigger than f13. You could probably open it up to f11 or f9 and get a little sharper image out of it...Ray

Btw, this is the first 60mm micro AF model Nikon made--mine is from around 1991. Thanks for all the compliments.  Edited by DVCollector
