I have seen several of these lenses on eBay, 25mm, 50mm, etc with f/1.4 aperture and including a c-mount to Micro Four Thirds Adapter. Are these lenses any good, they are remarkably cheap? What are the pitfalls, apart from "you get what you pay for"?

 

Do you mean cine-mount lenses? They may not cover the format, even for mF/T. No harm in trying if you can afford it.

 

I understand that C-mount is actually for cine-cameras, yes. Quite good appraisal here:-

Hi Roy,

Thanks for link, no time to look now though. Should be possible to work it out: 35mm c-mounts will cover mF/T obviously and possibly/probably APS-C as well. 16mm will probably work with the small sensor CSCs like the Nikon One series.

Have fun!

Cheers,
Oly

 

I use 3 C mount lenses on my Pentax Q - 2 of them certainly wouldn't cover MFT. They're CCTV lenses, and are a lot of fun, but not all that good - but what do you expect for the price?

 

You'd have to define your expectations. I have a Fujian 35mm f1.7 which set me back less than twenty pounds on Amazon including the bundled C>E adapter and extension rings. I love it but others may find its field curvature and flare compromises they cannot accept.
