You are 1 hour and 1 minute lateHow about a Canon RF 600mm f5.6 DO IS [Mk 1] for $7,399?
Or are you talking more like the old but super sharp and fast focusing EF 400mm f5.6?
I just picked up a 50mm f/1.0 (mostly as a collector's item). But with my luck, there's an RF 50mm f/0.87 L on the way.
What are you going to put on that 2x extender?
Hi Tony,I own the Sigma 14mm f/1.8 for astro. It's great! but it's a DSLR lens, and Sigma makes it for the Nikon F mount, which means they had to design their optics around a very small opening with a big flange distance. That's a big deal for fast, super-wide lenses, which benefit the most from the wide openings and short flange distances of modern mirrorless mounts. Canon could certainly make a 14mm lens one stop faster for their R mount. No doubt it would be huge, but so is the Sigma, and it's always on a tripod, anyway. BTW, the vignetting isn't ever a real-world problem for me... We've been testing the Canon 24-240 RF which has serious vignetting and distortion at 24mm, but the camera and Lightroom both automatically correct for it in post, which means you never see any problem with your images. I am fine with that.
F7.1 is the new Black. So...Would it not be a new f/5.6?, given the 400 f/4 DO isn't overly cheep.
Canon is the only remaining mainstream lens manufacturer without a reasonable 50mm lens that belongs to the 21st century, which is quite astonishingly ridiculous when you think about it (even Pentax has got one). All of their 50s bar the €2300 RF 1.2 are either yet another version of the decades old double gauss or barely evolved from it, with all that entails in regards to IQ (ie they're terrible by 2020 standards), and all of them with appalling AF.
Personally I'd like Canon to chase a level of ambition as high as Nikon tried (and not fully successfully so) to reach with the 50mm 1.8 Z, without IS (as IBIS is coming and I'd rather have Canon put it all in IQ), and without the Nikon's issues with onion rings / manufacturing problems, and I'd happily pay between €450 and €700 for it, but I'm rather expecting Canon to target a lower level of ambition with such specs unfortunately.
I would have thought such a reasonable, practical lens likely to end up in lots of hands and as a result quite a bit more likely to produce interesting pictures, a priority, at least more so than lenses designed to enable Canon's marketing department to trumpet the size of Canon's engineering appendage, but what do I know ?
