radiolaria at 13.5:1

Post by mtuell »

I got a "new" lens, a Zeiss Triotar f/4 135 mm prime, from 1951 or so. It takes nice pictures, but I wanted to try it out as a tube lens. Here is my first attempt with a 20x Mitutoyo M Plan Apo on a Nikon D3300 APS-C sensor.

I did two stacks (of 16 and 14 exposures) of the same field of dry-mounted radiolaria fossils, changing the lighting (moving the flash farther back) between. There are features of each that I like and don't like, but neither is likely the final word! :D

One of these may make in on my stereo gallery, but I might just try again...

Anyway, overall, the Zeiss Triotar seems like a decent quality, non-vignetting option for the 20x Mitty. I'll try other objectives as well as looking at a resolution target, in comparison to using the Nikkor 55-200.

Honestly - I don't get it. It looks like a bunch of clutter to me. I think using a microscope would be much more productive on this subject. Just my opinion.
