SuperDave...in a thread some time ago, you stated that we still didn't know just how good the 105PN was since all my comparison photos were with the Nikon camera, blurred by shutter shake. Well, I finally got around to making a comparison. It was at request of one of the forum members over on Photomacrography.org. He requested I compare the 105mm Printing Nikkor with the 105mm Apo EL-Nikkor and the 110mm Rodenstock Scitex S3. Here is a link to the results: http://www.photomacrography.net/for...06391#106391With the T2i, the 105PN absolutely shines. It surpasses the other lenses hands down! In previous tests, I didn't see that much difference between the 105PN and 105AEL, and I believe the ambiguous results were due to camera limitations. |

That lens is simply nuts. Can you shoot that same coin with the 75ARD and post the two shots here? Not for any reason except I want to gaze at them.  The T2i may not push these lenses to their limits, but it's very, very darn close. It reaches toward 3000lph, easily the equal of the full-frame sensors on the market. You'd have to shoot film to push a lens any harder than it can. There's a 105PN at absolute auction on ebay right now. Would that I had the available cash to get in on the action.  |

I do plan to add the 75ARD1 and 75ARD2 to the tests, as well as 90ACHM and possibly the 95PN. Maybe later this weekend, I still need to mail my taxes.
You are right about the sensor resolution definitely pushing the lens. The pixel size to get 18MP in APS-C is quite small and reduces the diffraction limit for the camera compared to earlier models with larger pixels. What I was referring to was simply that it is APS-C rather than FF so it doesn't cause problems for the lens due to sensor coverage, corner sharpness issues, field flatness, etc.

Ah. True that. Another argument in favor of APS-C. |

I did some tests on a wider range of lenses and published again on photomacrography.net, same link as above. I tested the 105PN, 105AEL, and 110RS3 again and added 95PN, 90ACHM, 75ARD1, and 75ARD2. I only did the tests at 2x magnification because the 95PN and 75ARD2 were optimized at 2x, while the 105AEL is only rated from 2x...20x so I wanted to fit within the accepted range of each lens. As it turns out, the 105PN was still the clear winner among all these lenses, though at the center the 75ARD1 was second in line. Interestingly, the 95PN was not as good as the 75ARD1 at the center but better at the edges, similar to the 75ARD2...Ray
