17mm TS-E f4L
85mm f1.2L II, alternatively 135mm f2L
300mm f2.8L IS II, alternatively 200mm f2L IS
24-70mm f2.8L II
70-200 f2.8L IS II
Have and use all these, couldn't put together a better list if I tried, every one of these Lenses falls into the great list.
The 85f/1.2 L II I did find slow on my 5DMK 2 & 1DMK IV, but on the 5DMK III and particularly on the 1Dx I find it a responsive Lens, not fast, it has a Fire by wire system, so it's never going to be a speed King, but it's SHARP.
I agree also with Eldar on the 16-35f/2.8 L II, nice Lens, but, has some real distortion at the wide end, I use this Lens now mostly for my Underwater Imaging where the corner distortion isn't so noticeable, I have read a lot of Peoples comments that are Positive re this Lens, I may have a less than perfect Copy not sure, but it's not a lens I ever recommend.
The 14f/2.8L II is better in my opinion, again, not perfect, but few Ultra Wides are, but the 14 does a pretty good job I feel.
The 24f/1.4 L II is also an excellent Lens, some Purpling in Star Shots, but renders well in normal use.
I have both the Canon 35f/1.4 L and the newer Sigma 35 f/1.4 and between these two I would plug for the Sigma, not to say the Canon is a slouch either, but I feel the Sigma 35 does the job better.
I'de like to see Canon produce a WA Zoom as good as the Nikon 14-24f/2.8, I use this on my 5DMK III & 1Dx using a Novaflex Adaptor, makes it Manual, but lovely Lens.
And welcome to the Light Side.
