Seb Farges tested a few C-mount lenses on the Panasonic GH1. The video on top shows the [shoplink 17068]C-mount Canon zoom 25-100mm f/1.8[/shoplink] lens performance. The lens is vignetting between 25 and 50mm and it’s also very heavy. He posted a second daylight video here: http://vimeo.com/16156795.

And he also tested the [shoplink 17179]C-mount 17-102mm f/2.0[/shoplink] (See video below). There seems to be less Vignetting on that lens.

There are many other C-mount zoom lenses. If you tested some of them feel free to share your image/video samples! Thanks!

Some very nice video work here!
Would it be possible to use only middle of sensor data = no vignetting.
Thought GH2 will have this feature. Am I right?
ADMIN thanks for the post ! 🙂
Could you please write my name Seb Farges (and not Fargas) thanks
Milos: It should. My GF1 has that feature. Just use ‘digital zoom 2x’ and it will crop out the center
the GH1 also has this digital zoom 2X feature, but the GH2’s feature will be different… How ? I don’t really understand, actually GH1 has a digital zoom 2X. GH2 will have “M ez” setting, the same tele conversion feature than in still picture mode.
Great, thanks. Does it mean that it zooms in while retaining full resolution?
Yes Milos, it seems to mean so. As soon as I have theGH2 in my hand, I will confirm it 🙂
These videos look very soft, maybe because its manual focus…..
I think the GH2 indeed crops the sensor in digital zoom modus, so gone is the vignetting. But how about noise?
I will certainly buy the GH2 (byebye E3).
Here is an review of the 20 1.7
http://www.lenstip.com/index.php?test=obiektywu&test_ob=269
the videos look soft because I only use the lens with the aperture full opened @ 1:1.8. Usually sharpness on lens is better around 2.8 for example. But using full aperture gives like an “organic” feeling, and not a too much video style.
As said in the post you have a daylight test of the zoom here : http://vimeo.com/16156795 , which shows this “organic” estheticism .
I’ve just put online another test with a cheap 30$ CCTV C-mount Fujia 35mm 1:1.7 lens here, also fully opened @ 1.7 :
