Dare I say new Sigma 300 mm f/4 and 400 mm f/5.6 in ART line, compatible with the excellent Canon 2x III and 1.4x III, with f/8 AF firmware update coming for 5D III

All this just makes me wonder how long it will be before some innovative company comes along and 'Black Magics' Canon, with an EF mount body having something like 1DX performance at a 70D price.
I've had great results with my 5D3 + 70-200 IS II + 2x III shooting field sports in Servo - f/5.6 was much more limiting, under stadium lighting, than the AF speed.
I disable any non-cross type AF points, though, so I only get the center stack to choose from with this combo. I'm not sure what performance is like when using the left/right outer points.
for portrait I have a 70-200L 2.8 II and a Macro 100L 2.8 IS, I use the lens on a 5D mkIII.
I have tried the 50L on the 5D III and it is fast and super sharp, I have read a lot of negative comments about this lens but my experience was very positive. I had a very short time with a 24-70 II at B&H today and it was a lovely lens.
We’re told Canon is holding press events on Tuesday, April 23, 2013.
The unit performed flawlessly in all the above-mentioned areas. For example, the photo below shows my YN-568EX firing in optical slave mode, using ETTL metering, HSS and 8:1 ratio set via the camera menu. Fantastic! To obtain the photo below I mounted my 580EX ii master inside an Apollo Orb softbox at camera right.
In general, I shoot a little bit of everything from landscapes to candids to street to my family. For those of you who own both or have tried both, what are your thoughts?
