Testing various ‘legacy’ 50mm lenses on the Panasonic GF1

Following lenses have been tested (click on the link to see the lens on eBay):

1. Canon 50mm f1.2 LTM
2. Canon 50mm f1.4 LTM
3. Leica 50mm Summilux f1.4 (first version) – M fit
4. Jupiter 3 50mm f1.5 (copy of the Zeiss 50/1.5)
5. Leica Summicron 50mm f2 (pre-asph new version, 1980s-1990s) – M fit
6. Leica Summicron 50mm f2 (pre-asph, chrome older version) – M fit
7. Voigtlander Heliar 50mm f2
8. Leica Elmar 50mm f2.8 (old M fit collapsable version)

It has been a huge surprise for me to read from the test that the Coigtländer Heliar showed the post performance! Do you agree?
