Default CCTV lenses for m4/3 and e-mount

Today arrived my CCTV lens 25mm/1.4 ... $ 24 incl. shipping
Now I am waiting for (nonvignetting) 35mm/1.7 ($28) and NEX adapter


camera, adapter, macroring, lens - macroring is included





SDXC reader works well :-)



25mm - of course shows vignetting - you can cut away (second picture)
all other pictures: ooc, no cut away

I like the "Holga" effect on the cabin at F1.4 !!!!!!

I hadn't thought of using one that way before. I have a TV zoom lens at F1.4 that I'll have a go with....

For a while I participated at a forum that has very active m4/3 members and they use all sorts of lenses with their m4/3 cameras, CCTV being one of them. Some produce decent results, others not as good. At one point I was thinking about buying myself a couple of these C mount lenses but then decided that I'd be better off using the money toward some good m4/3 lenses instead. You got some good results with your 25mm. However, vignetting is a problem and it kills the benefits of having a WA lens. By the time you crop the corners off, you are at least at 35mm anyway. Nonetheless, there's always the fun-factor of playing with those manual/unconventional lenses.

Boy, what an ugly (and primitive-looking) camera!

Today arrived my second CCTV-m4/3 adapter, first (above) is a little bit shit: no red point visible, no stop screw, very thin smooth edge, not easy to remove.

New adapter (only few bucks more) is usable for CCTV-25mm and M42, has a good visible red point, stop screw and is easy to remove.
