I'd like to start a discussion on a well-maligned category of lenses. What are your favorites?
For some reason, I have been accumulating f/2.8 SLR zooms from ye olden days. Can't say it's cheap or easy when Konica AR is your mount of choice, but some of these were motivated by buying a half-frame FT-1. I have found that for focusing, there is a ton of difference between f/2.8 and even 3.5. I also question how people ever focused f/3.5-4.5 (or slower) zooms using anything but specialized focusing screens. Microprisms don't clear and split image screens require ultra-precise eye positioning. None of this is a problem with an f/2.8 zoom, though.
My guess is that the bad rep of most 70s and 80s zooms came from two things: objective tests that measured them as resolving less (which no one would actually see in real life) and then difficulties in focusing or keeping steady at the customary small apertures. You start plugging SLR lenses into a Leica digital M, which can shoot at 1600 or 3200 ISO without breaking a sweat, and you find yourself surprised.
Some quick takes based on some testing using a Leica M240 and TTL focusing at magnification:
Tokina AT-X 24-40mm f/2.8 - a very short-lived lens in manual focus mounts, it is sharp as hell but exhibits some visible barrel distortion when you get too close. Given the way that this bells out at the filter mount, and given the close relationship between Tokina and Konica (one of its biggest shareholders), it only makes me wonder whether it is a cousin of the 21-35mm M-Hexanon Dual. I'm going to cover this on my site, but the AT-X 28-85 was supposed to have been a Zoom-Hexanon....
Vivitar Series 1 35-85mm f/2.8 - this super-weird (and very maligned lens) is a varifocal lens whose barrel rotates when it zooms but not when it focuses. I am not sure where people get that this lens is "soft," unless it's bad focusing or its propensity (serious) for sidelight flare. It seems quite sharp, especially in the central zone, wide-open. Maybe its issue was a field shape that just didn't work with film.
Konica Varifocal Hexanon AR 35-105mm f/2.8 - not really maligned except for its massive size and heft, clean examples of this don't seem to exist anymore. All-internal zoom and simple extension, non-rotating focusing, it is probably the oldest zoom (or varifocal) lens that is any good. Quite sharp, assuming you can focus it adequately quickly with your subject.
Tokina AT-X 60-120mm f/2.8 - unusually expensive in any mount, this cult lens is about the size of a 135/3.5 SLR lens, with a 55mm thread. One-touch zoom, push back for telephoto, pull forward for normal-ish. The reputation for good bokeh is well deserved, and this lens has quite a bit of pop to it. Close focus seems really far these days, almost 4 feet.
