But one must buy and test many many lenses in each focal length, to determine which is best.
And best for what? Just at 50mm (not counting 52-55-58) I find these each 'best' in different ways: FA50/1.4, Yashinon-DX and SMC-M 50/1.7's, Meyer Oreston 50/1.8, Zeiss Tessar 50/2.8 (Exakta mount, 12 iris blades), MacTak 50/4 (1x). Nearby 'bests' in their own ways are: Chinon 45/2.8; Tomioka 55/1.4; Mamiya and SuperTak and Petri C.C. 55/1.8's, Helios 58/2.
Other focal lengths aren't so crowded but the principle remains. Say around 100mm: the Vivitar-Komine 90/2.8 macro isn't the Meyer Trioplan 100/2.8 nor the Enna Tele-Sandmar nor Isco Westar 100/4.5's, nor the SuperTak 105/2.8. All of various sizes and qualities and purposes. The Viv is huge and sharp, the Enna is tiny and quaint. And of course...
