I had the Sigma 120-300 for quite a long time, it was a bit too heavy and slightly slower focusing than the new canon 100-400 but it was amazingly sharp. If canon put out one I would think it would be considerably lighter and have native autofocus and stability so would pretty much be amazing. Was my go to lens for owls at dusk and was still excellent with the canon 2x teleconverter.I still wish Canon would come out with a 120-300 f/2.8, or something like that. Hard to swallow that Nikon has such a useful lens and Canon doesn't.
DO doesn't do much for the weight especially of the glass and the glass optics would be still freaking huge.A 500 f/2.8 DO would seem to be nearly a perfect lens. Long, bright and possibly still hand holdable. If it took me 10 years to save up for the 500 f/4 I think this would only be viable with a lottery win....fun to dream
More ridiculous lenses for RF if true. Stop dicking around and just release a 200 f/2, 300 f/2.8, 500 f/4 and 600 f/5.6 DO
We need something for the mortals too. Where is a 200-600 type of lens under $2000?
Sony has a great one, Nikon will have one too soon.
Interesting. I hadn't heard that. Most of the reviews I have read have been pretty positive. Good to know. The only thing holding me back on the 35 or 85 is that I already have those lenses covered in EF. I'm hoping that we see a smallish 50 soon, but it at least now feels like they are trying to hit the standard, pro, and ridiculous lenses.Yeah, the 35mm is small, and I was considering this as my next lens, but it seems to have pretty bad vignetting and a lot of coma.
