I did a lot of research yesterday and came to the conclusion that I prefer the images produced by the Zeiss over the Sigma.
As an autofocus lens it’s autofocus leaves a lot to be desired. Optically it is magnificent but there has been a fair bit of negative chatter about its autofocus capabilities.
For the kind of photography I’ll be doing with a 135mm I don’t need autofocus as much as with shorter focal lengths.

Hhave a look at the shot of Proxima (crop, from 1/2 way to the corner of the frame, I will try to post the full frame later today) here: http://www.iceinspace.com.au/forum/s...31&postcount=7
Canon 100mm F2.8 FD is also very good (but shorter... ).
I have both, they are excellent for wide shots |
Looking for a lens that I can effectively use at F/2-F/3.5 in astro. The Canon 100mm gets great reviews but it won’t fit on my Nikon D810
