DJero Posted April 19, 2009 Share Posted April 19, 2009 I'm about to work with an XDCAM EX-3 and a letus ultimate adapter. has anybody worked with ultra prime or master prime (arri/zeiss) lenses? i know that master prime are faster... do they have better response in low light situations over the ultra primes?? and what about the sharpness and image quality? or should i get other lenses (cooke or another) thanks., Link to comment Share on other sites More sharing options...

If T/2.0 is fast enough, use the Ultra Primes or Cooke S4's. Link to comment Share on other sites More sharing options...
Premium Member Oliver Christoph Kochs Posted April 19, 2009 Premium Member Share Posted April 19, 2009 Hi, IMHO for most DOF adaptors you have to stay way below an f-stop of 2.8. Otherwise the grain of the ground glass becomes too visible. I doubt that you can see any difference between the two types. I use the P+S mini and Pro35. The difference between let's say Zeiss Primes and i.e. a Nikon lens at the same f-stop can hardly be seen. I coudn't tell - exact when racking the focus because the photo-primes do breathe a lot more than the film lenses. Link to comment Share on other sites More sharing options...

Should look way better than any adapter. Stephen Link to comment Share on other sites More sharing options...

Premium Member Oliver Christoph Kochs Posted April 19, 2009 Premium Member Share Posted April 19, 2009 Hi David, the EX3 has its own mount but there's an adaptor http://provideocoalition.com/images/uploads/VMI-DSC00677.jpg Link to comment Share on other sites More sharing options...
DJero Posted April 20, 2009 Author Share Posted April 20, 2009 Thanks. Hi Oliver, this adaptor works for the Digi-prime lenses? B4? Link to comment Share on other sites More sharing options...
Premium Member Stephen Williams Posted April 20, 2009 Premium Member Share Posted April 20, 2009 Thanks. Hi Oliver, this adaptor works for the Digi-prime lenses? B4? The Digi Primes are B4, the widest I think is 3.5mm so you should be OK on the wide end as well. Stephen Link to comment Share on other sites More sharing options...

(And I'm the kind of guy that will try anything) Having shot on a ps technik PL to B4 adapter on front of a F900/750p a couple of times (and not loving it for anything demanding) I don't feel the above combination represents good hire value. Surely a Red 1 with a very small set of SS/UP (or similar) would be similar in cost and far more useful? As for Digiprimes..? In the UK they are very expensive and I am unconvinced of the value of the match... They do look superb on the F23 or Viper. Also Digiprimes wide open on a 1/2 inch chip would be like shooting (DOF) at nearly 5.6 with a 35mm lens imaging on a 35mm sized plane. How many stops of light loss does the letus cause? regards and good luck Michael L Link to comment Share on other sites More sharing options...
