IMHO, wide & ultra-wide lenses, and good cheap wide (<50mm) primes.
Considering Canon just entered the cinema camera & lenses business, and therefore would probably invest R&D resources in developing lenses for those, I wouldn't expect much news in the DSLR lenses market.
[OK, some of the cinema lens designs might leak into the DSLR market, but - as noted - those cover APS-C sensors, I guess any such lenses would be EF-S.]
Last time I do shoot an indoor event, im direct in front of the stage, so i need 24, but also long end. 70mm to less
105mm are ok, but can be more. So 24-70 it to short. 24-105 only f4.
But if I go for an 1Dx I can use my 24-105 even in low light :-D
Anyway, what I'd really love would be to have the quality of lenses such the 50 1.2 and others packed in smaller bodies.
I know it's optically impossible or hard for nowadays tech, but imagine the quality and all the rest of a superb lens in the body of i.e. a 35 f2 body....that'd ridicolous.
It would be my dream as for a streetphotographer weight metters.
I know, i could go the leica way, but hey...I need to live with moneys ahah.
All in all I'd love more pocketability in the L prime lenses around..50 1.2 is already near...if just the 35 1.4 II would arrive and would be smaller, more compact lens...it'd be awesome!
EDIT: that's why I went the non L lenses prime way....and that's what I'm really missing in the line up, the "pockability" (more of a dream than reality as of now)
To stretch the ideas a bit, roughly speaking the faster the lens the shorter the zoom ratio. E.g. f/2.8 lenses are typically around 3x, whereas at f/6.3 I believe the SLR lens record stands at 15x! And primes of course tend to be fastest but don't zoom... I wonder if there's room for some ultra-fast short zooms. For example, today I would have loved a hypothetical 85-135 f/2L over the 135/2L and 85/1.8 combo I had.
Haha, I'm missing everything. All I have is my 18-135mm on my 60D. There are a few lenses that I really would like to get in the future when I'm not so crap on money. 17-55 2.8 is definitely one I'd like to have. As well as a nice wide angle for landscapes. I also want a fisheye one day. I think it would be fun to experiment with when not taking other photos.
I know that equipment isn't everything, but lately I've been getting so discouraged with not being able to take the photos I'd like to take.
