Hello,
I have several questions regarding Schneider Apo-Digitar 210 T:
1. Schneider brochure states that there are two Apo-Digitar 210 T, one is f5.6, another is f6.3. What's the difference between the two versions, and which one is better for a digital CMOS?
2. What's the ACTUAL image circle of the lens? Schneider states 120mm, but since the ACTUAL image circle of Schneider 180 T is larger than what Scheider states, is the ACTUAL image circle of 210 T also larger than 120mm?
3. How is the resolving power of 210 T on high resolution CMOS such as iq4150/cfv 100c? Is the Schneider 210 T better than Rodenstock Apo Sironar S 210 on digital?
Thank you so much in advance.
