Hi all,
Maybe seems a little bit of redundant question considering it's a lens and not some kind of newfangled body, but thought I'd reach out as I have a new RS 40mm lens on it's way to me – via the factory to get mounted in a new copal shutter – and wondered if anyone could share some insight with regards to it's use / limitations / etc. while I wait. It may actually be quite a long wait, what with the Covid-19 virus causing havoc with global travel and trade...
Anyway, Linhof and Studio have been awesome in arranging the mounting of the lens cells in the Copal 0 shutter. I use a Credo 60 on a Linhof Techno, so this is essential for me.
I'm wondering what information people can offer on the following:
1: I know there is a hard vignette / disk in the lens to limit movements past a certain point. In practice, if focusing in the middle distances, at what point does this show up? I've never once seen the disk when using my 70mm HR W lens, even when dropping the back a good 8mm and shifting +/- 17mm to create panoramic images. Different spec'd IC I know, but still...
2: Distortion. How are people correcting the complex moustache distortion the lens exhibits? Any tips on this front?
3: Diffraction. On the 60mpx FF sensor, how does diffraction look comparing f11 to f16?
4: How fragile have people found the lens? I've heard reports that it requires somewhat special care when packing because of the stress the large lens cells puts on the shutter unit. Is this true?
Anymore up to the minute info to share would be great, too. It's a well known, loved and tested lens at this point and I know a lot of people have reported on its performance, but maybe new versions of C1 etc have improved / changed things a bit over time?
Anyway, looking forward to receiving mine. It has been a much missed FoV in my kit, and now my perfect three lens kit is complete – save for the fact that I'd like to replace my RS APO-SD with the Schneider 60mm XL...
