Question about cctv

[Deadbear77]

Hello,

So I wanted to try my luck with a c mount cctv. I ordered a 25mm 1.2 and an adapter. It takes nice pics but there is a lot of "black" vignette. Also the aperture blades already broke and are stuck about halfway closed. Today I ordered the fujian 1.7, anyone have this lens? Does it also create a lot of vignette?

Thanks in advance.
Kevin

I did have the 35/1.7, very very foggy, hazy, you name it. Nice pictures possible, but I wouldn't say usable by default or without heavy PP. Sold it. I'm sure there are many very valuable CCTV lenses, but the dirt cheap Chinese lenses are not worth more than what they cost, IMHO...
