Disclaimer: THIS IS NOT A RUMOR, JUST A WISH LIST OR THEORETICAL LENS.
Just out of curiosity is there anything that would keep Canon (or any other maker of APS-C of FF SLRs) from making an f/2 zoom like this? In theory, the lens would be identical to the size of a 70-200mm f/2.8 (and likely just as expensive - if not more so), and would act like an 80-225mm f/2.8 with the 1.6x crop factor of APS-C cameras. On top of that it would make a killer portrait lens on a full frame camera and could replicate 4 other lenses (50mm f/1.8, 85mm f/1.8, 100mm f/2, and 135mm f/2) with the flexibility of zooming and added benefit of IS.
Adding on a 1.4x teleconverter would make it a 70-200mm f/2.8; a 2.0x would bring it up to 100-280mm f/4.
What do you guys think? Would you be interested in such a beast? I know Olympus has made a line of f/2 zooms, just wondered what the CR community would think of one in the Canon mount.
yeah i would be keen i made a similar thread a while ago about 2x f2 zooms you zoom range and aperture is possibly a bit aggressive i was thinking of 20-40 f2 a 50-100 f2 and a 100-200 f2
of course they would be insanely expensive and huge but totally awesome
