Are Ilex and Acme lens shutters reliable and accurate after many many years of u se? And, perhaps more importantly, how do they compare to contemporary Copal an d Compur shutters? I am thinking of buying some older Goerz lenses that--more o ften than not--come mounted with ILEX or ACME shutters, and not having ever used them myself, I don't know how good they are. (I am only used to Copal.) If you were buying the lens yourself and you had the choice of purchasing the same len s in an earlier (1950's, 1960's) ILEX vs. a later (1970's, 1980's-present) COPA L (or COMPUR) shutter, which would you choose, and why?
Also: Is it true that ALL the old Ilex shutters had two-hole flash outlets, rath er than the standard single-hole outlets common on all lenses made today? If so , is it easy and inexpensive to have the old outlet converted from two-hole to s ingle-hole?
Thank you very much.
