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.,

Rephotographing an image off of a groundglass as in a 35mm adaptor, you're not going to see a difference between a Zeiss Ultra Prime, Super Speed (except at T/1.3), Master Prime, Cooke S4, etc.

I'd only spend the money on the Master Primes if you need the T/1.3 speed. If T/2.0 is fast enough, use the Ultra Primes or Cooke S4's.

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.

Hi,

As you seem to have money to burn, why not get digi primes & shoot wide open? Should look way better than any adapter.

Can you use B4 lenses on the EX3?

Hi David, the EX3 has its own mount but there's an adaptor

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.

Hi

I don't know anything about your project and it there may be considerations I am not able to guess.... however I am struggling to believe you could potentially be faced with a shoot that included a lowish end camcorder, with a spinning ground glass adapter and Master primes. (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
