Ivan, Just remember that 645 will give you stop-down metering on K-mount...:-)
I believe most of the 645 lenses are excellent performers on digital. I have used *istD with the A*-300/4, and like it very much. I have also used the A*-300/4 extensively with the FA-75/2.8 reversed, for extreme macro photographing, and with excellent results. A note of caution, though. The 645 lenses are heavy. The A*300/4 does not have a tripod mount, and feels like a bit too much for the K-bayonet. When mounted to a tripod, there is vibration. My solution has been to use a long-lens cradle like this one from Manfrotto (link to B&H): http://tinyurl.com/hrrgg or: http://www.bhphotovideo.com/bnh/controller/home?O=productlis t&A=details&Q=&sku=126662&is=REG&addedTr oughType=categoryNavigation Jostein On 9/14/06, Ivan Shukster <[EMAIL PROTECTED]> wrote: > I have two questions about lenses > > 1) On Monday night at the local photo club meeting there had been a box of > goodies someone donated to the club (we do not know who) besides chemicals > and 5 67 mm polaorizing filters and 5 flashes there was also a 28 mm 2.8 > Sigma H.L.
