For starters, these are the only two posts on the WWW that has information about this lens:http://www.minolta-forum.de/forum/4homepages/details.php?image_id=7054http://www.flickr.com/photos/kenwales/4277800414/#
*UPDATE, now there are 3 posts on the WWW! Antony North (owner of The Rokkor Files) has released a review of my lens...since it's rare he obliged to review it: Minolta RF 800mm 1:8 review on The Rokkor Files
Here's my flickr set showing many more sample shots and even HD video of the moon taken with this beast: http://www.flickr.com/photos/motleypixel/sets/72157625159796808/
So here’s an unusual find, at least for me. The Minolta RF 800mm 1:8 Catadioptric. When I acquired this lens last month I immediately began work on an EOS mount. Knowing that it had zero aperture mechanics I was sure it was going to be an easy conversion. The only question I had in the beginning was whether or not the screw-in filter (screws into the Minolta RS mount) was required or not. Well after some searching I came across a good review of the Minolta 500mm f/8 RF Rokkor-X
and in this review Antony does point out that the screw-in filter should stay in for performance. So know this set me back a little, but I got it figured out.
#1 The package:
#2 The guts:
#3 The mounts. On the left is a machined M42-EOS adapter with an epoxied 42-to-39mm reducing bushing which, to my astonishment, works as a perfect mate to the screw-in 39mm filter.
#4 The EOS conversion complete (non-destructive, i.e. this is fully reversible back to stock). The ONLY removal of Minolta stock I had to do was 1mm of the Minolta normal screw-in filter housing. Also shown is a hand-crafted aluminum filter key:
#5 Here’s the lens along with the Canon EF 17-40mm f/4L USM for comparison:
#6 LOL, give a photog a mm and he’ll want a few more
