Hi All,
I'm considering buying the new Rodenstock/ALPA HR Alpagon 4.0/50 mm SB34. Wondering if anyone knows:
1. Is this the same as HR Digaron - W, optimized for larger digital sensors.
2. Is the lens any good as a shiftable WA lens on the Alpa STC or MAX? (I realize that there is only a 90mm image circle, but that is as large an image circle that will be available on the new Rodenstock/ALPA 40 and 32 with the SB17).
3. Why does it need a HPF?
4. I've been told a center filter is not recommended/needed... any thoughts on that?
Thanks in advance for any guidance you can give,
Bob
