No substitutes . . .

Having almost given up the search for a fast 135mm lens, I’ve been surveying shorter focal lengths with ultrafast speeds. A couple of the china lenses would have been pretty impressive but for one thing: the rendering of the 75mm Summicron-SL is stuck in my head.

Although it doesn’t obliterate backgrounds the way faster glass can, the impression of subject-background separation is still strong because it is so high-resolving wide open. A challenge occurs, though, when the subject is a bit farther away, in which faster glass is a necessity.

A bigger challenge with a lens like the TTartisan 90mm is focusing, as I found out the other day when I tested a copy. I might not have noticed but for the fact that it was an A/B pair of shots on the same subject, taken in sequence. The one that’s not accurately focus looks pretty good. The one that is focused accurately looks great.

Now if I can just get it through my head that nothing ultrafast will come close to what the 75mm Summicron can do, then accurate focusing will come with practice. That’s if . . . .
