Now that Canon has announced theirs and there has been plenty of reviews of it, I’m wondering when we can see competing products from the likes of Sony and Nikon or third parties like Tamron or Sigma? I’m new to photography and haven’t yet grasped the cadence of releases like this. Do competing products come around pretty quickly or are all of them just blindsided by this and maybe more than a year off from having a viable product?
Sigma’s 24-35mm f/2 Art is the only other full frame lens with a constant aperture under f/2.8 that I can think of.
Not only is it a much shorter zoom range than the 28-70mm, but it appears that its been discontinued, so the 28-70mm is the only f/2 FF zoom on the market now.
