Thanks for the comments Steve & Brian. Regarding a tripod collar, I found this thread: http://www.dpreview.com/forums/thread/2888491 recommending "a Lens Collar for Canon EF 70-200mm/F4L from ebay. They also come in black. I bought a couple of the black ones that I am using for some other purpose. BTW, these are the same tripod collars that can be used for the Pentax-FA*300/4.5."
I'm a bit surprised to find a number of people using the 54B for astrophotography (a torture test for lenses). This page recommends it (along with a couple of Pentax lenses) for example: http://www.gyes.eu/astro/camera_settings.htm On Tue, Jan 13, 2015 at 2:18 PM, Brian Walters <apathy...@lyons-ryan.org> wrote: > Quoting Darren Addy <pixelsmi...@gmail.com>: > >> I tripped across a manual focus lens last night that I was not >> previously aware of: The Tamron SP 300mm f5.6 Flat Field (model 54B), >> an Adaptall2 lens.
