Not having AF is obsolete in my book. I got over that in the 80s.
Subjective priorities. Most of my 135mm shots are stills or portraits. When I need AF and flexibility, I reach for the 70-200/2.8.
About obsolete, just compare the two lenses side by side to realize how much better the Zeiss is.
I am not sure I would use "obsolete" but antiquated sure comes to mind. I do not care how great the optics are, if you cannot nail focus you still have an out of focus image. I have a few manual focus lenses but I find them very cumbersome to use which probably explains why I do not use them much.
Would a 135 1.4 IS lens the size of a 300 2.8 IS or a 200 F2 IS really be hailed as a goto lens? Especially for the 5-6k price tag it would create?
I'd rather have canon come out with a larger 85 1.2 II with IS and have zero CA and improved sharpness across the frame. This would be MUCH bigger seller than the 135.
I doubt it but then again I am not so sure my idea of a larger and faster 135mm would be such a big seller either that's why I posed the question. I would buy a larger and faster 135mm lens with IS before buying the 200L 2.0 IS and definitely long before buying a larger 85mm even if it had IS or less CA. The 85L needs a focus limit switch before anything.
