Just to start start the flow again, if that's really necessary....;-), I purchased a 500mm f5.6 Tele-Tessar for my SL66 at Photographica (UK) last month. I cannot remember the full details of the thread from few months ago, when one was offered on eBay but as these seem to be rare and feeling that it was a fair price, I added it to my kit while the opportunity was there. I have yet to use it so will be interested to see what it can do but have first to think of suitable subjects...... The downside is that this is a preset lens but when attached to the camera and held by the tripod mount on the lens barrel, the balance is perfect and easy to pan. Because of this, the overall weight and size does not 'feel' excessive. Being reasonably fast it gives a bright image in the viewfinder. I hope to have the time to see what it can do but do not plan to do any back-packing at present! John Obviously the list is working, I guess everyone is just away. --- Richard Knoppow Los Angeles, CA, USA dickburk@xxxxxxxxxxxxx --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
