canon 50mm 1.4 vs sigma 50mm 1.4 vs zeiss 50mm 1.4

[gandhi]

If I had the 24-70 mk2, I would have the Zeiss 50, but I don't so i would probably go for the Canon 50/1.2 as the length of that lens lends itself to AF. 50mm and 85mm I would use for people shots and fast AF is very helpful and the 50/1.2 is fast and accurate and wiiiide.
At 35mm and 21mm the Zeiss wins hands-down for me.

I have never used manual focusing till now, is it easy or does it needs to be mastered before getting zeiss?

Zeiss has a fairly long focus throw, so they are relatively easy to manual focus.
Back focus with 50/1.2 is not an issue if further than a metre away, I have never shot closer than that with it.
These 5 are all great lenses with superior IQ. The two (2) Zeiss are MF and very different and both very good.
Because I have a few 77mm filters and you would also have a few already owning the 24mm, the Sigma offers great IQ and the same filter size and is probably best value for money for you.
