Cosmicar Television Lens 25 mm 1:1.4 [C-mount]

25 mm is a standard focal length for micro four thirds cameras (eq. of 50 mm for Full Frame aka type 135). Luckily, there are many lenses with C-mount that would work perfectly. So far I mentioned only Fujian 25/1.4, that was a cheap tool available. Recently I've found a bargain Cosmicar Television Lens 25/1.4 with slightly distorted filter ring and oily aperture, but with perfect glass condition.

Carl Zeiss Jena DDR Tevidon 16 mm 1:1.8 [C-mount]

Tevidon 10/2 was a great pick! Later I've found Carl Zeiss Jena DDR Tevidon 16/1.8. A bit narrower lens from magnificent Tevidon family. This time it's so called "zebra" housing, because of polished stripes on focusing and aperture rings.

Cosmicar Television Lens 12.5 mm 1:1.9 [C-mount]

After testing Tevidon 10/2 I got my hands on Cosmicar 12.5/1.9. It's a bit narrower lens, produced in Japan with C-mount. It's easily adaptable for Micro Four Thirds. All you need is a simple C-MFT adapter, no need for additional dedicated mounts as for Tevidon.

Carl Zeiss Jena DDR Tevidon 10 mm 1:2.0 [C-mount]

It's been a while since I've been updating here. I've been working on my art [feel free to check it here], travelling and doing many boring things. However it was also time to get new lenses and test them. I've managed to get some nice C-mounts: Tevidon 10/2 (below), Cosmicar 12.5/1.9, Tevidon 16/1.8 and Cosmicar 25/1.4.

Let's begin with Tevidon 10/2 I bought as bargain and loved since the moment I attached it to the camera...

Minolta MD Rokkor 50 mm 1:1.4 with Focal Reducer [MD]

Since I've got my Focal Reducer, I used all my lenses with it. Recently I've found a bargain Minolta MD Rokkor 50 mm 1:1.4 with a little bit of fungus. It doesn't affect photos at all and the price was good. So I decided to buy it, when realised there are no MD adapters allowing focusing infinity. As I like to use my lens in any given condition, I designed and printed my own adapter.

Canon TV Zoom Lens V6x17 17-102 mm 1:2.0 [C-mount]

Canon TV Zoom Lens V6x17 17-102/2.0 was the first C-mount zoom I've ever got. First of all, it was smaller than I suspected. It makes the lens perfect for multi-purpose use. It's 16x zoom with very fast aperture of 2.0.
Secondary, I've read somewhere that it's supposed to be parfocal, that is - focused on the narrower length (102 mm) will stay in focus throughout the whole zoom range. It was really pity, that mine wasn't. What's more - it didn't focus at 17-20 mm at all! Luckily - there was a simple trick and now everything's superb!

All in all, it became my favourite lens for shooting squares and filming.

Samyang 10 mm 1:2.8 with Focal Reducer x0.7 [EF > m4/3] - first impressions

In my search for perfect ultra-wide angle lens I came across Samyang 10/2.8. It's relatively new on the market, but already astonishing. It's supposed to be very wide even without Focal Reducer and very fast at the same time. But hey, if you're using M4/3 camera with tiny sensor, you should demand the widest and the brightest you can get. So let's push the lens to it's limits and mount it on Focal Reducer 0.72x!
