I'm in the process of ordering a APO Leica-R Elmarit 100mm F/2.8. My understanding is it has a filter-size of E 60. What does that mean? Can I get a regular B+W 60mm UV filter or is there a special filter I have to get for this?
B&H sells Leica filters that are "E 60" but they're a fortune! If a regular B+W works that would be a great relief.
On another related question, this lens was made in 1986, the first year they came out with this particular lens. Should I get a UV lens or a clear lens, given that it was made when FILM was the only medium? What happens if I got a clear filter, would I have a bluish color shift on a Canon 5DSR?
Thanks,
Bill
