Being a landscape guy, I'm loving the 16-35 f/4 right now, but I'd like to see some love for 85mm, my favorite prime focal length, incorporated into the zoom lineup though. For me, the 16-35mm f/4, a 24-85mm f/4, and a 70-200mm f/4 with a focal length marker for 85mm (which I plan to manually add to my existing model), along with an EF 1.5x would be an ideal kit. Full coverage 16-300mm, with two overlapping focal lengths between each zoom. Plus easier math on the tele-extender front; I didn't get into photography to think about numbers, dammit. The 24-85mm would be optional kit for a lot of shoots, particularly with a 50mm f/2.8 pancake in the bag. I imagine they went with 40mm because it makes for a similarly useful lens on full frame and APS-C, at 50mm, APS-C crop pushes it a little too much towards telephoto. I think the the 24-85mm is a possible replacement to the 24-70 f/4 in 5-10 years. I doubt the extenders are going to change and I also doubt we'll see another 50mm added to the lineup. Anyone have insight into why 85mm gets no love in the zooms? I don't have a mark for it on my 24-105 or my 70-200.
