Hey, pulp_writer - many thanks for these tests. I have both the Som Berthoit 17-85mm and the 17.5-70mm, and this is the first indication I've had of how they might perform.
I've gambled and picked up a range of lenses early - Som Berthiot zooms and more practically, Kern-Paillard Switar primes - in hope of beating the inevitable rush. The real time to do this was right when the M4/3 format was announced - if only! - but I still saved quite a bit over where these lenses are now, and where they'll be going after the BMPC hits the streets.
I'm going to stay on the lookout for tests of the Switar 50mm, 25mm, 16mm and 10mm, as they're small and well suited to keeping a low profile with the Pocket Camera. Thanks again for your work.
