By "old and slow prime" I meant that it's not very popular in 21st century . The 24/2.8 is a much more desirable lens. Too bad it's not F2 . It is weird that a full stop aperture difference means nothing to you. I shoot people with my 28/1.8, so the blurry corners at wide open are not terribly problematic. But I cannot imagine using the 28/2.8 IS instead. It would produce absolutely different results and the IS wouldn't help a bit. Even for landscapes, the distortion would make stitching tricky or even questionable and 28mm is not wide enough to one-shot everything. Stitching 40/2.8 STM is a breeze - so sharp and well corrected. Canon need to make a new 20mm prime , IS or not, but F1.8 would be nice (like the Nikon one). However, I'm not going to buy a bunch of slow stabilized primes ($500-$600 each) in steps of just a few millimeters. That's madness. I'd just get a decent UWA zoom instead. Perhaps the Tamron 15-30/2.8 VC, or the EF 16-35/4L IS.BillB said:Quote from: BillB on June 10, 2017, 07:46:09 PM
And the 28/2.8IS is a joke because... ?
Isn't the price doubling of an old and slow prime after adding IS, a joke? Thank god the 35 IS is not F2.8 . Same thing with 24/2.8IS.
I don't know ... maybe I'm wrong. What are you shooting with your 28/2.8IS? What's the best use for it? Shooting video on EOS-1D
28mm2.8IS has a new lens formula with an aspheric element and USM as well as IS. Greatly improved resolution over previous 28 is well documented. Not the same lens as the one it replaced. I use a 28 where others might use a 35, with a bit more width. You use the 28 1.8. I use the 2.8 IS. No joke.
