I checked the newly listed Pentax auctions this afternoon and spotted this one: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1396197613&ssPageName=ADME:B:EOAB:US:6 Obviously, it was listed incorrectly. Now it just so happens that I've been looking for a 2X converter for my 6x7. The pictured converter is the late model version, and it's reportedly brand new. It was listed with a buy it now of $300. KEH gets $450 for a like new copy. So I figured, what the heck, I'll do a buy it now. The seller was quite pleased that I wanted the converter and didn't demand the 300mm lens, although I could tell there was no way she was going to part with the lens for $300. I plan on using the 2X converter with the 300/4 lens that I already own. I know I'll never be able to afford a 600 or even a 400 for my 6x7, and I'd like to do some occasional wildlife photography with the big camera. I know I can shoot handheld with fast film and max shutter speed, but I'd like to use this 600mm combo off a tripod as well. But I doubt if even the sturdiest tripod can control vibration on that kind of rig. I seem to recall that Bogen made a lens support that can be used to help control big glass hanging off the end of the camera. Has anyone used that setup? Paul Stenquist
