tis a handsome looking lens all right but it does not fit the bill for a
conventional non-retrofocus lens does.  even a biogon,a relatively huge
conventional classic semi-symetrial lenses(ever see the 75 compared
to any other of its type)would be practically flush with the body.
furthermore as i pointed out previously a conventional wa lens of this
focal length would be absolutely unthinkable w/o a conventional centre
filter of aa least 4x. Next: the back element of a conventional type at this
focal length would certainly block the through the lense metering. no one
would waste the kind of money involved to producing a lense such as this
that blocked any and all through the lense metering systems. whoever
translated the spec probably left out something like "equals the
performance.etc" anyone care to bet on this? ralph
