I'd be interested a new RF wide lens, make it small and compact please Canon

It should be compact!

15.45 and 16.48 are suspicious numbers.

The patent numbers and what it is marketed as always differ. And of course the marketing tends to be the more optimistic one.

None of your lenses are truly what is written on them.

If this has IS... it's a buy!!

The 2.8 has IS, don't see why this wouldn't.

Did a comparison of the RF 15-35 f/2.8 versus these new lens designs. They're about identical. This suggests that there would have to be two things to make that design work: IS and the UD elements required for the f/2.8 design. Implications: it will be spendy. The 16-35 version of the new patent is significantly smaller than the 15-35 version.

Interesting that widening to 15mm instead of 16mm makes the lens 16mm longer. I've shot a lot of EF14mm/2.8 and love a wide view. In principle I'd love a 14-35/4. But is it going to be massively bigger than a 16-35/4 could have been?
