enny Posted June 30, 2013 Share Posted June 30, 2013 Hi guys i got my self sankor 16c with 52mm clamp. I also have canon 50 1.8mm lens which has vignetting. Now what is the best way to avoid vignetting with sankor? i seen some videos with 50mm fd 1.4 canon lens and it looks like vignetting is gone are fd lenses preferred with sankor?. My last question i got this lens for panorama video shooting what lens would be good here with sankor with no vignetting. Thanks Link to comment Share on other sites More sharing options...
Gábor Ember Posted June 30, 2013 Share Posted June 30, 2013 You have to use longer lenses. You may have better luck with a Helios-44. It is 58mm f2.0. It is just a little bit longer but it MAY just be enough to eliminate vignetting. It depends on the amount of vignetting. You may need a 85mm lens to get rid of it totally. The Anamorphic Guide has a part where you can see which is the widest you can go on which anamorphic. Sankor 16C / Singer FF - 135mm APS - 85mm M43 - 50mm This means the Sankor 16C vignette below these focal lengths (Full-Frame, APS-C, Micro 4/3 respectively) What camera are you using?

Gábor Ember Posted June 30, 2013 Share Posted June 30, 2013 Also you should push the anamorphic as close to the taking lens as possible to reduce the vignetting. I think FD lenses are used on GH2 and such M43 cameras (they can't reach infinity on EOS bodies), that is why they don't have vignetting. Link to comment Share on other sites More sharing options...
Tito Ferradans Posted June 30, 2013 Share Posted June 30, 2013 most important thing of all: which camera are you using? Link to comment Share on other sites More sharing options...
enny Posted June 30, 2013 Author Share Posted June 30, 2013 thanks guys canon 60d Link to comment Share on other sites More sharing options...
Gábor Ember Posted June 30, 2013 Share Posted June 30, 2013 In that case 85mm is the lowest without vignetting. Get a Jupiter-9, they are solid, can hold the Sankor, and they can be very sharp even wide open. Or crop your images/videos. But you will get the same field of view that way and worse image quality.

Tito Ferradans Posted June 30, 2013 Share Posted June 30, 2013 No no, a Helios should do just fine. On the 5D3, you need 85mm to avoid vignette, but ~60mm should suffice for APS-C. Link to comment Share on other sites More sharing options...
enny Posted June 30, 2013 Author Share Posted June 30, 2013 so to get this right guys helios 44 and Jupiter-9 should do the trick but i would need a adapter to use them on my 60d. So 60mm and up should be ok without vignetting? I also have lens canon 55-250 ef. Why do people use fd lenses with sankor is there anything wrong with canon ef lenses 60mm and up, i mean for those two lens i will need a clamp to use them on 60d? thanks guys Link to comment Share on other sites More sharing options...
Tito Ferradans Posted June 30, 2013 Share Posted June 30, 2013 Zooms tend to look bad with anamorphics. Rotating front zooms are even worse, and modern lenses don't go well either. Link to comment Share on other sites More sharing options...
enny Posted June 30, 2013 Author Share Posted June 30, 2013 so when you guys say 66mm or 85mm you mean prime lens not zoom lens non of that 55-250 crap Link to comment Share on other sites More sharing options...
Tito Ferradans Posted July 1, 2013 Share Posted July 1, 2013 yep, primes are the best. :P Link to comment Share on other sites More sharing options...
