Was there a market for a fast 28-45mm? They did it anyway, and will reap the rewards of critical acclaim at least, if not sales. It's an ART series with lavished attention in design and finish, where the 28-70mm is a DG DN Tamron competitor with attendant shortcuts built in.

My reasoning, if you can call it that, is that the three variables are: aperture, range and weight. So if (IF) they can replicate the image quality of this breakthrough lens, they have to vary the mix. I'm thinking aloud above.
I figure the main barrier to greater acceptance is the size and weight, nothing new there. If they could have done a wider range - which would gain them more sales interest - at even the current weight, they would have done so. But it would have become a Canon-esque 1500 gram item, for elite event pros.
Aperture does seem to be sensitive, even critical, doesn't it? And that is how they are promoting this one, and you see people's bokeh images here. But at 28-45mm there is real resistance too. So if they relax the aperture a little and keep the image quality over a more central range, that's my thinking for more acceptance.

For f/2.4 or whatever me it wouldn't be distinctive enough from f/2.8 zooms, and not close enough to the primes. The latter is the most important for me.
I don't consider this zoom as the one and only zoom in the bag. It's even not mainly operating in the ball park of zooms.
I'm thinking more of a bag filled with a 24-104mm f/4.0 or 20-70mm f/4.0 or 28-200mm as the main zoom, and some added primes for low light, shallow DOF and better IQ, say a 28mm a 50mm and an 85mm f/1.4.
In that context this 28-45mm doesn't replace any zooms, but it does replace two primes, with in between focal lengths and no lens changes as a bonus. In that context the weight isn't a huge problem as it's not on the camera the whole day.
Personally I don't like 35mm in a prime as it's too compromised, nor here or there. I like 28mm, but it takes lens changes as I can't do everything with it. I like 50mm the best, but sometimes I do want to go wider (I can force my self to accept not having wider, but it hurts sometimes). If going without zooms I would change the most between a 50mm and 28mm prime. This 28-45mm f/1.8 solves this.
f/2.4 brings a lens closer to zooms for range, and some or many will like that, but it sacrifices the prime replacing capability.

Weight is a understated reason to nix a lens, but it's very real. If you have two lenses, one at 950g and the other at 650g, it's an easy choice. I want to see them go from a quality first angle of attack, trading off the variables to get the best result. This one is just too large/heavy for travel for one thing, and its range means you would be often swapping out other lenses. Zooms are very hard, and they are pioneering novel focal length ranges to see what happens. What would you want if you were in this market sector? ...Show more →
I'm often leaving the house with "redundant" lenses: a heavy version and a light weight version. RF 28mm f/2.8 stm pancake + Sigma 28mm f/1.4 Art for instance. Or the FE 28-60mm next to another zoom. It allows me to get rid of the weight on the camera when I don't need the bright aperture.
It never happens with the EF 40mm f/2.8 pancake + 40mm Art, but it's possible. (the 40mm pancake isn't that great and I happen to prefer a compact zoom) The 85mm DN isn't that heavy the Samyang 75mm f1.8 is needed next to it in my bag, but it could be another example as well. (I'm only bringing the Samyang when leaving the Sigma at home.)
And this is how I think of the 28-45mm as well, I would use it next to another zoom weighting less and/or giving more reach.
There's a third perspective: the bag with primes only: 28+50+85mm for instance. I think this lens saves you the majority of lens changes when replacing the 28+50mm, however, in this context the weight is limiting, as an f/2.0 28mm or an f/2.0 50mm can weight considerably less than this 28-45mm zoom. 85mm is usually the least on your camera, so the 28-45mm will increase the weight in your hands a considerably amount of the time you're using and carrying the camera.
