hi all, its good to see others using these tiny lenses and sharing their findings. i recently picked up a bolex 8mm version from a polish seller for myself and a baby hypergonar for a mate. ive used both and love both! i really did not want to give the berthiot to my pal least ive still got access to one hehe. they both have good points, both are sharp if used correct with a suited lens .with the bolex i use the konica 40mm 1.8, plus i have great success using a 28mm f2 kiron lens with no problems to the image atall... though you have to be almost against the glass. the thread size on both lenses is the same so home made bolex mount can screw into both. ive used a fair few setups now in the last 3 years and think my new arrangement works nicely. currently on just a gf1 now hacked and plan to buy back a gh2 as my main cam, i used the mkii with a tair11 135mm and a sankor 16d but this setup was huge and forced me to snap and scale down. the sankor and tair combo produced some fantastic footage but moving it around was not fun! really liked sebs footage and it was from that i was inspired to look at the berthiot and then stumbled onto the bolex 8mm. i will hopefully be shooting some music videos this year with a few mates so will really put these little gems to test!
