I'm (also) looking for an Angénieux 25mm in c-mount for my G1.
I already have a Canon TV16 f:1.4/25mm which has its own advantages : very small, in perfect condition, very short minimum focus distance of about 20cm, fully covering the sensor at this focus and almost full cover at infinity.
The image quality is quite good even wide open but given its optical formula (almost macro), the depth of field at "normal portrait" distance (around 1 meter or 2) is so so. Let's say that it's a good general purpose lens with a lack of character compared to other c-mount 25mm like the Angy.
Also consider that despite this weak point and a quite pronounced barrel distortion, I only paid 25€ for it !!!
If you are interested here are some samples as well as some taken with a f:2.5/75mm Angénieux at :
(lot of post-processing in LR but almost no cropping)
I had the opportunity to test an Angénieux f:0.95/25mm type M1.
The image quality is impressive but it really not fully cover the sensor, the barrel distortion is also quite pronounced and... it's very expensive.
I saw many pictures taken with its little brother the f:1.4/25mm (Type S41 I suppose) and it seems that this is really the lens to have instead of the f:0.95, and may be the best overall c-mount 25mm for this G1 purpose :
- Apparently fully covering the sensor (or is it because all these images are cropped ?) ;
- the barrel distortion seems very limited ;
- wide open, the depth of field and bokeh style is almost equivalent to the f:0.95.
I would be really delighted if someone could share his knowledge about this lens.
