Hey Brian....ok I haven't any experience with the Zeiss 35 f2, but I have rented the 21 2.8 and the 50 f2 Makro Planar, and I can tell you that they are stellar lenses. As per the examples above, the have great contrast and colors...and bokeh. the only one I didn't like(also rented), was the Zeiss 85 1.4. the bokeh was phenomenal, but it just wasn't sharp wide open. check out Diglloyd.com for examples and comparisons against L lenses in great detail(unfortunately, it costs).


I wouldn't hesitate to rent the 35 f2 from Lensrentals.com, and find out yourself. But, at the same time, I use a sigma 30 1.4 on my 1D4 on a regular basis, and it shines pretty well!! I can't use it past more than f4-f4.5 because of the larger sensor than 1.6x, but that's not why I have it...I want and use it from 1.4-f2 99% of the time.


Good luck with your decision.
