I forgot to mention that I have a Tamron 500/8 mirror lens myself, and I
quite like it. I have used it for shots of my mates surfing, and for the late
2000 total lunar eclipse. I have been pleased with the photos I have had from
it, but haven't really used it much, since I bought it in about 1993-94.
I did a search at Jessops for Sirius lenses and found only 1, a zoom. There
are lots of Tamrons there, and almost everywhere else it seems, and usually
plenty og Vivitars and Sigmas. I suppose these were the big 3 independent
lens manufacturers of the 80s and beyond.
One thing to watch out for with Tamrons is you have to find the
interchangeable Olympus OM mount to go with it, and these got very expensive
new, although I think you can probably pick them up used for a tenner or 15
pounds maybe.
I mentioned the one at Ffordes because I think it came with a load of Olympus
gear they got recently, including my 16mm fisheye which just arrived from
them this Wednesday. ;-)

I nearly always forget when I put on my 500/8 CAT lens, that I have f/8 and
ONLY f/8, which can be a pain if you have 400 or 800 ASA film on a bright day
and every shot is overexposed!
At f/8 of course, the split image/microprism is more or less unusable
(darkened), so you have to rely on the matte / ground glass of the screen,
althugh I find that OK. Of course, you can always change focusing screen to
one suited for slow telephotos.
The daytime shots I have done were mostly handheld, maybe leaning on/against
something nearby, but of course you will need 1/500 second or faster to avoid
camera shake. So basically at f/8 that gives you 1/500, 1/1000 (and 1/2000 on
some OM cameras) unless you have a tripod. With the 600, camera shake will be
marginally worse, because of the extra magnification.
I have wondered about trying a 300 or 350mm CAT/mirror lens - anybody have
any experiences to share or recommendations?
Kind regards,
Dave Bellamy.
