Thanks for the tip off phobus. I think I got there just in time this morning, as soon afterwards they re-placed the advert and now they're selling them off in lots of 5. The thing is, logically, there are plenty of mounts for attaching other lenses to cine cameras but not the other way round (who'da thunk it?), so can you tell us all where you got your Taiwanese C-mount adapter?Speaking of cheap experiments, I got a C mount adapter from Taiwan, and the Carl Zeiss Jena Tevidon 25mm 1.4 from eBay and its working out quite well for about $100 total for both.

I can't tell the aperture exactly because I mounted the aperture ring upside down to get the lens to mount closer to the sensor for infinity focus.
Great tip! I'll try that tonight!Make a mark in the lens mount where the aperture should show when the lens is mounted on the adapter (and the camera), then dismount the lens.
Unscrew the 3 screws on the lens mount, rotate and position the mount close to the marked position and screw the screws back on. You will now have the lens that would focus to infinity while you can also see the focus/aperture scales on the lens.
Rabenwolf, from whom I ordered a C->G1 adapter warned me that the Chinese adapter is limited in the diameter of the C-mount lenses it can accomodate while his is not. The picture in this link seems to confirm his sayingHi, I got it from this thread - http://74.125.93.104/translate_c?hl...ge%3D1&usg=ALkJrhi_hQOZPEpXAhTI1xf6MbfYon4iEA

Rabe says some Chinese adapters he has seen will for instance not allow the Kern Macro Switars to be mounted which have a back diameter of approx. 38mm. The recessed C screw mount on the picture seems surrounded by a ring that might do just that. I can tell more once I receive the adapterThis one doesn't have that limitation either.
About ¥10.000, coming soon.

OK, don't know if it will fit what you want to put on it but for $25 I went ahead and ordered one (Postage to Europe is $6 on top, plus 4% Paypal = total of $32.24). Send an email to the guy who makes them. He's just improved the original design and I think from the photos at least, that it's easier to work with.Any idea if a Canon 0.95 c-mount will fit in the cheap adapter? If so - how would I go about ordering one?
Thanks!
Thanks. I did email him - he says:OK, don't know if it will fit what you want to put on it but for $25 I went ahead and ordered one (Postage to Europe is $6 on top, plus 4% Paypal = total of $32.24).

So it will not reach infinity with my Canon. Maybe the next version released will...The largest diameter is 36.5 mm that is best for infinity location.
If the diameter is over 36.5 mm , less than 47mm.
It can fit the adapter,but can not to infinity.
1) The photo in post #53 above, appears to be a C-ltm adptr -- m3photo, is that what you ordered for $25 +s/h? Or a direct C-to-G1 adptr?

I hope it's the newer model the seller is offering, although you're right in suspecting it's an LTM type as there don't seem to be any lugs visible on the rear face, maybe my mistake in copying and pasting the shot, sorry.
This one is the older model:

By the way, Hawk Peng says that the price for the newer model is $35 - Add postage and 4% PayPal.
We need to clarify some things:
1) The photo in post #53 above, appears to be a C-ltm adptr -- m3photo, is that what you ordered for $25 +s/h? Or a direct C-to-G1 adptr?
2) GDI, re post #54, I assume the specs hawkpeng emailed you were for his C-m4/3 adptr, right?
A needed spec is the depth is that 36.5mm opening?
How did you get such good focus from this lens? Mine's either a dog or it needs a lot of machining ...Speaking of cheap experiments, I got a C mount adapter from Taiwan, and the Carl Zeiss Jena Tevidon 25mm 1.4

Here is a diagram I found on the dvxuser.com website (in the section devoted to the RED camera) that may help visually explain the different coverage areas of various kinds of cine and CCTV lenses. From Peter M's data above, it appears that cine lenses covering the "RED S35" frame will have some safety margin on Micro 4/3, and lenses for "RED 35" will be close:A rough indication could be given by the film/sensor size in mm (data from Wikipedia):
4/3 : 13x17.3
M8 : 18x27
16 : 7.49x10.26
Super 16 : 7.41x12.52
35 : 18x24
The only lenses covering the whole μFT sensor according to these values would be cine lenses intended for 35mm. Other lenses, such as some Super 16, may have a larger coverage than theoretically needed.
