Hey guys, while this thread is active, it's probably a good time to let you know that I started a blog on mirror lenses back in June:
Through the CAT's Eye
As you can see, there's not much on there, although I plan to dress it up in the near future. My plans for the blog was to make it a collaborative effort between various photographers (I already have 3 others signed up, including Peter Zack).
My idea for the blog was as follows: Have a section listing the most common mirror lenses available with specs and photos for each lens. In the blog section you'd be able to post a review of your mirror lens(es) and these posts would be linked to from the pages for each individual lens.
I am also planning to write technical articles about mirror lenses (history, optics, etc.) as well as tutorials on how to best shoot with them, how to post-process the images (or best JPEG settings), etc. Of course, if anyone wanted to contribute any of these, they would be welcome.
But the core of the posts I would like to be mostly of pictures. If you go for a walk with your mirror lens, you might want to come back and post a few examples of what you captured. Eventually, I'd like the blog to show up on the first page of Google results for "mirror lens" so people can see the great photos that can be taken with a mirror lens. Maybe someday we'll be able to erase the stigma associated with them for so long.
If you would be interested in collaborating with me, drop me a PM with your WordPress ID, or if you don't have one, the e-mail address you would like to have associated with your account. I will then send you an invitation to become a collaborator on the blog, meaning you can post whenever you want. Like I said, I'd like this to be a collaborative endeavour.
Even if you don't want to be a collaborator, you could still help me by sending some photos of your lens with the requisite specs (focal length, aperture, filter thread, rear filter size, weight, width and length). I would give you credit for the photos and data, of course
