I have not tested the 35mm but will
I have tested eight different 35mm lenses today (including the kit lens and some zooms at 35mm); I shall publish the results when I get down to it.
Lenses tested:
- The kit lens
- 3 Leica R zoom lenses: Vario Elmar 21-35, 35-70, Elmarit 35-70
- Angenieux 35-70 for Leica R
- Nikkor 35mm/2.0
- Ultron 35mm/1.7
- Zeiss Jena Flektogon 35mm/2.4 (M42)
To make a long story short:
All lenses were compared at f/5.6 (same as the kit lens). All of them provided good results on the G1; differences were small except for the Nikkor, which was not sharp, I might have a Monday-morning lemon.
My biggest surprise was the Ultron, which showed no smearing at f/5.6 and very little at 1.7, contrary to the 28mm I had tested earlier, which displayed heavy smearing.
Details will follow when I can upload more pictures. Right now I have reached my upload limit.
In terms of money, the M42 Flektogon seems the best buy ($100-200 on ebay)
