Hi, I'm thinking about buying a cooke varotal 18-100mm t3 and I'd like to know how this lens works on modern sensors like the ones in blackmagic production camera/ursa. It would be a good zoom or would you indicate another old cine lens?
 
Regards,

I love this lens!  My most recent experience with it was on 35mm, but I've used it on the Red Epic and Sony F3.  If you are shooting academy or super 35 format, it's a great lens for its vintage.  You will notice some gentle vignetting, especially when open at a T3.  In a not-so-scientific way, I'm of the opinion the vignetting is more noticeable on digital.  I'm not talking about cropped corners, but a gentle brightness falloff as you leave the center.

 

It does NOT cover over-sized sensors well though (i.e. 5k on the Epic or 6k on the Dragon).  So I would check exact sensor sizes and compare against the Super 35mm format.

 

I love the lens for its "cooke look" and surprisingly limited pincushioning distortion.  Any chance you can evaluate the lens on a digital camera before committing to purchase?

Dan Finlayson, thank you very much for the attention!
I found a great lens for U$8000.00 and I'll try to test it before I buy, but I'm not so sure it is gonna happen. Anyway, I'll take a better look about the vignetting for my camera sensor.
Really appreciate you opinion.

Best regards.
