John Mustarde used to show up regularly on the list, and had a page about long telephotos, including a few 500mm mirror lenses. As I recall, he raved about a specific Soligar or Spiratone, can't remember which, as being good. Google it; the page was up a year ago as I recall. One thing he mentioned is, that due to inherent low contrast, a manufacturer's hood is not a luxury with these beasts.
I think you're gonna find them tricky. I've got two 500mm mirrors, both F8. One is so old and big that it comes with a tripod foot and has yelllow single coating (pre 1970, I think). The other is much more compact. The #1 problem with these beasts is not donuts; it is focus. I only nail about 1 of every 4-5 shots, but my eyes are old. Have fun. My mirrors are strictly for fun; not suitable for 8x10 but not too bad for 5x7 prints. -Lon Aaron Reynolds wrote:
Oh yes, I know... and this is why I was asking about used lenses, which are traditionally cheaper. Buying a good used one for $100 is better than buying a lousy new one for $100. -Aaron -----Original Message----- From: mike wilson <[EMAIL PROTECTED]> The problem is; the less you spend, the less you will think.....
