So if I'm shooting with some nice classic FD-mount lenses, how much gain is there to be had from upgrading to more expensive glass?
To find out, I rented a couple of Zeiss lenses for the weekend, and shot some tests; and here are the results, in case anyone else finds them interesting.
Lenses I compared:
* Canon FD 24mm f/1.4 L
* Canon FD 50mm f/1.4
* Sony/Zeiss 24mm f/1.8
* Zeiss ZF.2 50mm f/1.4
* Sony 18-200mm f/3.5-f/6.3 LE (SEL18200LE)
Note that the zoom is the newer of the Sony 18-200mm f/3.5-f/6.3 E-mount zoom lenses; the original (SEL18200) is the kit lens for the FS100 and FS700, it's silver, and it's quite chunky. The new one is thinner and black.
All the test shots were recorded on a PIX-240 external recorder (which I also rented for the weekend).
Part 1 (this part) is the test shots (encoded at high quality), without the lens names, just because I think it's way too easy to fool yourself if you know the answers. You might want to download this to watch on your computer, so you don't get the streaming compression messing it up; the download button is below the video.
Part 2 is the results, so you can just skip to that if you don't want to bother with the blind thing:

Hmm…it looks like things are taking a while to load. Try again?
