I'm not Robert, but I do have Xenoplans in both CCTV and Compact series variants and also a few of these Fujinons. The Fujinons are massive compared to the Schneiders, the CCTV Xenoplans are reasonably large but relatively lightweight , the compact series are small but very dense. Thanks for the in...

But not 49mm filter thread. I thought that would help lead people away :D The CCTV Xenoplans have a 49mm thread. Hello Robert, Here's a link to information about Fujifilm's machine vision lenses, and data on what I think may be a CCTV Xenoplan equivalent lens. Are the Xenoplans you have that massiv...

This sounds as though the flashes may not be fully charged prior to each exposure. If you are using small flash units powered by AA batteries, you may need to use fresh batteries, and wait considerably longer than 3 seconds for them to fully recharge.

Re: Info On LMPLFL10X Objective

Regardless, I'll stick it on the end of a 200mm tube lens and update this thread w/ test images after I receive it. . It's designed to be used with a 180mm tube lens (such as Olympus's UTLU), but will work fine with 200mm, albeit at 10/9 its nominal magnification, producing an 11.1x magnification. ...

The Apo-Rodagon D 120mm f/5.6 is optimized for duplication at a 2:1 ration when used in the forward orientation, and at 1:2 when reversed. The lens would perform best as a taking lens at 1:2 ...
