Which c-mount adapter do you use? Which can you recommend that would perhaps allow for better clearance and rotating the lens so that the focussing scale is always up?With regards to the Lytar, the focus ring is so close to the c-mount adapter when mounted, it is very difficult to focus...I found it to be essentially unusable. A stiff focus ring would make it even worse...
I don't have the Lytar anymore so I can't look at the lens (I sent it back due to the lens being fogged) but many of the cine lenses have c-mounts that can be rotated. Those lenses that don't have this, can be used with the MS Optical adapter which is designed specifically to allow lens rotation so the focus scale is up.Which c-mount adapter do you use?

The Angenieux looks very good! How does it handle on the G1, is it heavy?In my Previous Post when I talked about min focusing distance I did mean cm not mm of course.
Here is some shots I took with Angenieux 75mm f2.5

Thanks, Monza. I have a 3" focussing lever for the Lytar that clamps around the focus ring (a necessity with the Bolex, especially with other lenses on the turret), but I suppose it wouldn't clear the recessed G-1 adapters either. A real shame, because the 16mm films I shot with the Lytar in High School 40 years ago were quite sharp, even when projected on a very large screen.I tried the Lytar on the Hawk adapter and the MS Optical adapter...the focus ring is essentially recessed into the adapter. Very difficult to get a grip.
I think milapse has raised an interesting point here.Greetings all (first post here..)
I'm here to help with the lens data base. Here's my current collection (I'll update the info as I gather it, some will be repeats):
Schneider 10mm/F1.8 (very sharp)
machining: no
coverage: no
Cosmicar 12.5/F1.4
machining: yes
coverage: no
Schneider 16mm/F1.4 (on it's way)
machining: I don't think so
coverage: 18mm (so I've read)
Angenieux 25mm/F0.95
machining:no
coverage: almost 16:9
Soligor 25mm/F0.95
machining:no
coverage: almost 16:9
Schneider 50mm/F2 (crazy sharp)
machining:no
coverage: yes
I think we should try to pin down the image circle on these lenses because I do find the non coverage lenses 'useful' albeit I'm coming at this from a timelapse/cinematic perspective (and thinking ahead to the GH1) for the following purposes (using peters 25/1.5 example):
This is how I've used the Schneider 10/1.8 with awesome results
This is how I see the GH1 with c-mounts being very interesting for 720p production...
FYI - For photographic purposes the minimum image circle you'll see from a 16mm film lens will be ~14mm this equates to just under 6 MP (3000x2000) on a 4/3. As sharp as these lenses can be (remember pro 16mm lenses were designed to resolve higher than 35mm lenses!) the lost pixels are completely negated by the quality of the lens.If we were to CROP the image as in milapse's 720p example and utilize not the full resolution (4000 x 3000) of the sensor, but just the 1280 x 720 required for video, could we obtain a full wide angle video image (albeit with lower resolution)?
Yep, we shall see... That's what I anticipate though. *crosses fingers*This might be a premature question because the GH-1 was just announced. And it might also be a downright stupid question. But I hope there's some food for thought here. Shooting true wide angle videos with, say, a 10mm Switar would be fantastic, wouldn't it? -- or maybe too good to be true.
At the moment Wolfgang Rabe (German) is making one and a fellow out of Taiwan who goes by 'hawkpeng'. More are arriving on the market as I type. Check feebayA mundane question: which c-mount to micro 4/3 adapters are people using?
I got one of the 75/2.5s in the mail today. It's a great lens! Very small, light, perfect fit for the G1. I'll take a photo of it on the camera.It handles like a dream
Its just a bit heavier that summicron 40mm, so my guess will be around 150 gr.
The focusing ring is far away from adapter, so no problem there.
