My FD->MFT and EOS->MFT lens adaptors arrived yesterday and I tested them out today with a bunch of lenses on my GF1.

The prime lenses I tested (in order) were:
EOS - Sigma 15mm Fisheye
MFT - Lumix G 17mm f/1.7
EOS - Canon EF 35mm f/1.4L
EOS - Arsat 35mm f/2.8 Tilt/Shift
FD - Canon FD 50mm f/1.4
EOS - Canon EF 50mm f/1.8 II
EOS - Canon EF 50mm f/1.4 USM
EOS - Sigma 50mm f/1.4
EOS - Canon EF 85mm f/1.8 USM
EOS - Canon EF 100mm f/2.8 USM Macro
EOS - Canon EF 135mm f/2L USM

And the Zoom lenses:
EOS - Sigma 10-20mm f/4-5.6
MFT - Lumix G Vario 14-140mm f/4-5.6
EOS - Canon 17-40mm f/4L USM
EOS - Canon 17-85mm f/3.5-5.6 IS USM
EOS - Canon 24-105mm f/4L IS USM
EOS - Canon 70-200mm f/2.8L IS USM
FD - Canon FD 70-210mm f/4

Now why am I telling you about this? Well, I posted the results up to a gallery on my website so you can look for yourself and compare the differences. For this test, all lenses were shot wide-open.
I also included a few shots of various lenses mounted on the camera body to give an indication of the overall size and ergonomics. The EF 70-200mm f/2.8L IS looks comical with the little camera hanging off the back of it (not even touching the table), but some of the other lenses (particularly the FD 50mm f/1.4) feel right at home.

Hover your mouse over each thumbnail to see which lens is used for that photo, or click on the thumbnail and then look at the photo caption below it. You can view a photo at full resolution by hovering over the main image and then selecting "original" from the menu that flies out from the side.

The results were quite interesting. Some lenses were a bit of a surprise to me, others not so. My favourites were the FD 50mm, EF 35mm, EF 85mm, and EF 135mm. The problem with the EOS lenses is that you cannot adjust aperture, while the older FD lenses are not only smaller but also have a manual aperture setting on the lens. I've got an FD 85mm f/1.8 lens on its way to me which I can't wait for.

Later this afternoon I went to visit some friends and took the GF1 with me. Despite a moving baby, using manual-focus wasn't much of a problem.
Here are some shots of my friends with the GF1 and FD 50mm f/1.4 lens mounted. The last shot is a bit OOF but was so cute I had to include it.
