Will Zeiss Standard Prime cover 4K in 2:1?

[Harcharan Singh]

Hi,
Just wanted to purchase a set of Carl Zeiss Standard Primes T2.1 (MKII)of 16mm,32mm,50mm and 85mm for my Red One.What issue can I face?
Will they cover 4k in 2:1?Here are some pics...Thks

Yes they cover 2:1 (and 16x9 Full sensor too) - One note: there is some very minor vignetting (invisible in most situations - like a subtle darkening of the edge of the frame) on the 32mm at wide open on the aperture. This disappears completely at T:2.8/4 (this is die to a long back element creating a portholing artifact))

They are very sharp and clean (looking IMHO sharper than superspeeds at wide open (speeds only toughen up IMHO at 2.8))

Hi,

I have seen portholing on the 16, 24 & 32. By T4 they are all even, some at a 2.8/4 split as you said. 50 & 85 are perfect wide open
