Spiratone 300mm f/5.6 Mirror Mintel®-S Kadlubeks Objectiv-Katalog does not list Spiratone lenses, but this may be the same lens as the Soligor SOL0350 300mm f/5.6 lens. There were variants on the Minitel® form- a Mintel-T and this Mintel-S, at least. Most of the "house" brands tended to go with the same suppliers at any given time. Preface Needless to say, this is yet another of my chain of posts on catadioptric (mirror) lenses and also on Spiratone gear. I had intended to do my 'new' Russian MTO 500mm f/8 lens, but that will need more effort than my flu-(w)racked body is capable of at this time (I am on the mend, though). Especially since the Russian lens will have to be done on a film body and with tripods and all. However, it is over 70° F here today, and so I stepped outside my door and took some snap shots. This lens is definitely in the "Classic Manual" era, and it is the lens that is the issue. I shot these on a Canon 5D mkii "full-frame" body. The images are completely unedited as they came out off the CF card. Introduction I had been bidding on the Spiratone (and a few other) 300mm catadioptric lenses for some time now. Never won. So I finally zeroed in on one and went all out. As has been the case before, this lens typically goes for more than most 500mm mirror lenses. However, this time I got one for only a little more than I paid for my Reflex-Nikkor 500mm f/8. Why was this one so sought after? •Collector demand? I don't think that the 'critical mass' has yet been achieved in those trying to accumulate the Spiratone legacy, although that might be comforting to my heirs were it true. •Small Size? Even the 500mm versions are relatively "hand-holding" lenses, but the '300' is even more compact and small (326 grams without adapter). I am sure that is part of the attraction. and the issue I was most interested in •Is it good enough that it is still wanted as a shooter? You can judge for yourself below. There are other sample shots at places all over the internet, such as http://www.dpreview.com/galleries/8109623540/albums/spiratone-300mm-reflex-lens .
