SERIOUSLY doubt Canon would throw IS into it though
Yeah, a 16-35 f2.8 IS would be absolutely massive (and expensive). Just look at Tamron's 15-30 f2.8 VC,plus the fact that it's a bulbous lens that can't take front filters.
As an occasional landscaper, that Tamron 15-30 just boils by blood. I want to love it, but chasing just 1mm extra cost them a front filter ring. That is now my gold standard example for 'worst lens decision ever'.

To each their own. It's one of my favorite lenses.
I have to agree with this. Canon have recently been really poor at supporting the APS-C platform with anything other than basic beginner offerings, like the recent variable aperture zooms. I have to assume that they make a decent amount of money off of these kit bodies, and anyone actually filling in things on the more premium end would be a boon for them.ahsanford said:But I have to disagree with the Sigma 18-35 f/1.8. Canon's not losing a wink of sleep over a Ferrari-like EF-S product that weighs nearly 2 pounds. That's a prestige item far more than it is a true threat to their business. If anything, Canon's pride is hurt more than their bottom line.
They did not give up filters just to 'chase 1mm.' They also did it to achieve better IQ than the 16-35L and all of Canon's previous attempts to make this lens work. Canon themselves did this by sacrificing a stop of light. Nikon did it with the bulbous front element and achieved even wider zoom with a lot of very expensive glass.ahsanford said:As an occasional landscaper, that Tamron 15-30 just boils by blood.

It's more than just going to 1mm that caused them to use the design they did. Judging from the excellent coma performance wide open at 15mm, it was a good decision.ahsanford said:e_honda said:Sabaki said:I'd be all for a 16-35 f/2.8 mkiii

I'd be really interested to see what fast ef-s primes would look like - in theory they should be smaller and cheaper than their full frame counter-parts (Sigma's 30mm f1.4 EX compared to the old full frame 50mm EX).
Don, it seems that you and I are still on the same page dreaming about this affordable supertele, I don't see why a 500f5.6L BR can't be under $3000Don Haines said:I'd like to see a 400F5.6 or even a 500F5.6 with BR tech.

+1, The changes I'd like on the 135L are not so much the glass, but rather 9-blade curved aperture, weather-sealing and IS.chromophore said:The level of chromatic aberration in the 135/2L and the 200/2.8L is already very low and quite adequately controlled. It is the shorter focal lengths and faster apertures for which CA is difficult to correct; and at very long focal lengths, CA correction is limited by weight and length constraints, for which BR would help mitigate.
I don't necessarily buy into the argument that production date should be a factor in deciding which lens designs need updating. Some lenses are quite old but have held up remarkably well; the 135/2L is one of the first that comes to mind. Some new lenses keep getting revisions but still leave something to be desired--I haven't found the various incarnations of the 16-35/2.8L to be particularly lust-worthy, for example. I'm also not a fan of all the slow- and variable-aperture consumer zooms that Canon seems to spit out every six months.
My personal thinking on this is that whenever a new optical technology is developed, it should be implemented in those lenses that would stand to receive the most benefit from its use. That of course does not always mesh with the profitability motive; but I think with BR optics, Canon should use it to update the 85L, 50L, and 24L primes, as these I think would stand to benefit most. Of the zooms, all super-wide and wide zooms have problems with lateral color; whether this could be efficiently further corrected by BR optics I am not entirely sure, but if so it would be welcome.
