A new toy arrived in the mail today. Actually it's relatively old, like a lot of my gear but it's new to me. It's a "2X CFE Teleplus MC4" teleconverter for Canon FD lenses for which I paid the princely sum of ninety-nine cents. I do feel ever so slightly guilty not paying more but I guess that's the way it goes when people list things on eBay for $0.99 and there's only one bid. I'll try to "pay it forward" or something...
The first combination I tried was the teleconverter and 100-300mm f/5.6 zoom on my AE-1 Program. After a little [user] trouble getting things mounted I was happy to note that metering worked as expected. Basically the teleconverter ate two stops (e.g. f/22 without became f/11 with), which is what my reading suggested for a 2X version. But for those two stops I do get 2X magnification... or a 600mm lens. In fact, this combination might equal or better my 600mm f/8 (fixed) mirror lens (although the mirror lens _is_ pretty sharp and the teleconverter optics might fail on that front).
And then it just got silly. I put the 600mm mirror lens on the teleconverter. So that's a 1200mm f/16 lens, which allows me to pick out small details on the roof of a shed two houses away. Of course, given that my personal film lab isn't quite up and running, I just had to try this on my 350D to see what it looked like. Out with the FD-EF adapter... and I have a [sort of] 1920mm focal length. Ridiculous! As is trying to hold the thing steady, so I'm off to play with this on a tripod now... ;) Photos soon.
