I really like it when a CR2 rumour appears. Though I even get more excited to see a CR3!
I have been in the market for a new Canon 50mm for a number of years. As I’ve written in a number of CR threads previously, each of the current Canon 50mm lenses has their strengths, but also their notable weaknesses. I really appreciate what Sigma (& Tamron) have been doing with many of their recent lenses, however to ensure forward compatibility (and most accurate critical AF) – I prefer Canon, as even the Sigma 18-35mm (as superbly sharp and ground-breaking a lens as it is) has been noted to have some AF niggles – which really takes the wind out of its sails for me.
A new EF Canon 50mm lens between f/1.4 and f/2 would fill the only ‘gap’ that I really have in my set of lenses. Ideally (for me) a Canon 50 mm would have very good IQ wide open (sharp, lots of general & micro contrast, low CA) - would have absolutely awesome IQ 1 stop down, FTM USM and close MFD. IS would be a (much appreciated) bonus.
As for what the other lens – I don’t ‘need’ anything else, though I know various people are looking for a new Canon UWA prime or zoom (eg 14-24mm), or a telephoto zoom (eg 100-400mm ‘mkII’). I can’t see Canon updating any of it’s current “II” lenses, nor updating any of their L focal length primes for which they have recently brought out a non-L prime (so I actually doubt a new 35mm L will be on the cards).
If there are 2 lenses coming out, maybe a new non-L 85mm prime, as the current 85mm is good, but could be a little improved upon, and the 85mm L II is not that ‘new’. Or, actually I’m thinking a new TS-E … at a new focal length.
