Then they never encountered the 180 Apo telyt. It has, according to U.S.
Navy tests I saw once, a center resolution of higher than 400 and edges were
375. No wonder people think they are consistent to the edges. Only Tech Pan
film has a hope of discerning a difference, and even then, testing technique
would have to be laboratory quality.

Seconded.  Without the benefit (?) of resolution charts, pictures taken with 
the 180mm Apo Tely-R f/3.4 just jump out at you.  This is one impressive 
lens, and available at decent prices on the second hand market.
