First, I've accumulated several unusual Sinar lensboards from eBay purchases, and I'd like to know what they are for, please.
This then segues into my other inquiry: I've been considering switching from Packard shutters to a Sinar shutter for my barrel lenses, not the least because all my larger barrel lenses are already mounted on Sinar boards (I use a Sinar-171 adapter board on my 171 Arca). I know that, for this purpose, there is no practical difference between the f4 and f5.6 versions. What should I look for in a well-functioning unit, and what cables etc. do I need to get to make it work?
Also, what is a good way to hold the lenses in front of the Sinar shutter? For the Packards I used a cobbled-together arrangement with a universal iris mounted in front of the Packard. This worked well for smaller Packards, but grew to be very difficult with the larger-sized shutters that were larger than the 171 lensboard and thus had to be hung out in front. If I could mount Sinar boards in front of the Sinar shutter, and mount the Sinar shutter on a 171 board, I'd swap tomorrow.
