I really like this shot. Well done, Alan.

Omg, that weight saving would be insane, probably a record...even now sometimes I question myself if I should replace it with the 28-70mm f/2.8 STM, mostly for the weight savings, BUT it would be exciting seeing a lens like that.
As I have written, swivel displays are often a bit dark in really bright environments, at least that's my experience. A real classic waist-level viewfinder also doesn't suffer from disturbing reflections. So I am sure that there are photographers out there who would appreciate such a camera design.I just flip up the rear LCD screen on my G7X III to get a waist-level finder. It's bright enough.
I think we need an automatic button to click everybody time this suggestion of making dedicated teles for APS-C is posted.Sigh. Because physics. Wide and standard lens designs are limited by the image circle diameter, telephoto designs are not. There is no point in a telephoto lens ‘for crop cameras’ since such a lens would work fine on FF. That’s why there are no such lenses.
Look at the Oly/OM 150-400mm, for example. It’s for m4/3 (2x crop) but it’s about the same size as the Canon 100-500 (and if OM made a FF camera, the lens would work on it).
As for wide lenses not making money, I really don’t get why some people seem to think they know better than Canon what lenses people will buy. I mean, Canon has led the ILC market for over two decades and dominates it today…but you know more about what lenses they need to make? LOL. You get to decide what lenses you want to buy, but Canon doesn’t care what you personally want.
The way technology trends come and go, such as film cameras having a comeback and vinyl music selling like crazy, it'll probably just take a few influencer or YouTube who state "they absolutely love the old, little M-cameras made back way then..." and boom: the m-system will be backOr, hear me out, Canon could revive what was one of the best compact systems of all time--the M series. Of course that ship has sailed, but the way that company handled that system was such a lost opportunity.
I fully agree!I wouldn’t like to say, but what I can say is that the optical performance of the RF 28/2.8 is really quite impressive, with superb clarity. So called ‘micro contrast’ doesn’t seem to suffer from the resin elements, there’s not a lot not to like.
It looks something like the spherical aberration correction lenses that used to be found in large refractor (lens) telescopes.Pretty amazing aspherical shape for that final element on the 24-45 mm f/1.4 L.

Exactly!Lenses these days are a two-part system: the physical lens, and the software/profiles needed for mandatory corrections. It seems to me that for manufacturers, the value is in the lens and not the software or profiles. If anything, giving away the profiles adds value. Having companies like dxo retro-engineer the corrections seems counterproductive to me.
Of course...we can all wish for lenses and hope that Canon makes them. But there's a significant difference between hoping for a lens and claiming that Canon not making the lens one hopes for will have negative consequences for their business. The former is quite reasonable, the latter (which is what @swingman did) is asinine.Well, I'm not the author of that comment but come on: Each of us has HIS preferred lenses (and of course Canon knows best which lenses will give them the most profit). And we are most interested to get the lenses we are dreaming of. Me too!![]()
The ray diagram is going to 'stop' at the edges of the diagrammatic 'sensor' by convention, even though that's technically the image plane and is thus a 2D surface.On the schematic of the 24-45, the transmission path of the edge rays do not go through the entire width of the central elements. Is this the constraint of the image circle at the focus plane?
I can intuitively visualize in a telephoto lens with a narrower angle-of-view the edge transmission path taking up more of the width of the central elements.
