Panasonic GH1

A hacked GH1 with PL mount..

This is a one off adapter using a SG Blade PL mount I modified to micro 4/3rds. Although bit of a lump it has the advantage over all the others I've seen in that it has back focus adjustment, which means for the 1st time I can accurately focus the Kinoptic Tega lens!

4/3 sensor myths....
You can use C-mount lenses but, Does the lens cover the sensor? -No, probably not if it's under 30mm. Nearlly all old c-mount lenses were designed for 16 to 8mm film gates, on M43 sensors you see far more outside this area than the designer intended. Eg Bell & Howell Super Comat 25mm vignettes in corners, Wollensak Raptar 25mm & SOM Cinor B 25mm vignette the edge of frame considerably, wider lenses fare much worse.
" .. full size stills lenses -Yes, but but wide angle, say under 20mm, are generally slow, difficult to find and expensive. They may lose contrast with internal light bounce.
" .. 16mm Arri/zeiss mk1/2 super speeds: 25mm and above ok, but 9 to 16mm vignette too much.. And much the same for all 16mm lenses.
" .. Tega 5.7mm -No, vignettes. see below
" .. 8mm (f3.5) Pelang fish-eye -Yes! OK and no vignetting.
" .. Pentax 110 -Yes! and no vignetting. But no iris control, set at max, f2.8 they are not at thier best. Probably the cheapest 18 & 24mm avaliable.
" .. Half frame or 35mm movie lenses -Yes, all of them.
