HI,
I am going out on production soon and have tested all my ideas on 35mm with standard speed Zeiss prime lenses which I like a lot. Now the thing is that I may get (almost sure) the Ultra Speed Z Set whichi si Zeiss too. I have never used them and it looks like I will not be able to test them. ANyone has worked with them? Can someone give me an idea of the differences? I understand they have more contrast. I wanted to test filters to make them much the Standards but as I mentioned, I will not have time to do this. Are they really different? I am finishing on print so I can't tweak the contrast in post. Any ideas would be great!
Thanks
Miguel

I don't find them to be particularly contrasty, nor low in contrast either. They can flare more easily, so watch bright lamps and windows (unless you like the flare.)

Oo.. do they flare to much? I meand I will have some soft sources in frame like fluorecent lights on the roof.
Thanks!
Miguel


David,
Thanks! You posted just before I putted the question. I will have bright sources like windows, no direct light but yes... some time the lamps will be in frame and I cant do anything about flaging them out...
and to make it harder I will be shooting on 24-35mm lenses most of the movie.
Any ideas on how to avoid the flare?
Thanks
Miguel

Well, how much flare is too much is a matter of taste. I can't tell you if you'll think it's a problem or not. It's much worse with the old Ultra-Speeds (the non-Z Series) than the Z-Series at Panavision. You'll probably be fine.

As far as I'm aware Panavision's Ultra Speed lenses are rehoused Zeiss Superspeeds (at least those that open up to T1.3 or T1.4). The Superspeeds themselves are a bit more contrasty with faster focus drop-off than the Standards.

What you mean by faster focus drop off?
The is less focus range back and front of the subject in focus?
Thanks

Yes. The difference between in focus and out of focus is much more noticeable than other lenses, say the Cooke S4s.

More contrasty lenses like by Zeiss tend to make the delineation between sharp and unsharp more clear and abrupt as you roll or rack the focus. Now whether that's a good or bad thing is a matter of taste.
