I should be getting a new lens soon to replace my kitlens. Wondering if the Sigma 24-70 f2.8 is better than the Zeiss 16-80. the Sigma is cheaper but has less range. It also has a bigger aperture.
I don't mind using either of these lenses for some macro work. won't buy a dedicated macro lens yet. Sigma has better macro than Zeiss. Zeiss also has QC problems and alot of vignetting. Any Comments on the sharpness and colours and bokeh of these two lenses?

Hi Cross-lane
I haven't used the Zeiss, so can't really comment on it's performance, however, I have got the Sigma 24-70 f2.8 EX DG and really rate it as a lens. I find it very resistant to CA (I have seen several shot where the Zeiss has a bit of fringing) and sharp enough. I have a 15x10 from a 5D printed that was taken wide open at 70mm and it's really very nice.
I had considered the Zeiss when I bought my Sigma, but as you say, I was put off by early QC issues (I believe that's sorted now), and also wanted a FF compatible lens that was f2.8 straight through.
See here http://www.alphamountworld.com/forums/photo-critique-forum/ongoing-signs... for a recent photo taken with the Sigma lens.
If you can, I'd try them both in a shop and ask them to print them out. However, I think you'd like the Sigma.

If I get the Sigma, then I will want to get some Sony Filters with the T* coatings. But does anyone have any experience with these filters? is it good? Does it help with CA, colour and contrast? If i get the Sigma then I will get 2 Protection filter with T* coating for my 50 1.4 and kitlens. Can I use two filters on one lens? and does it improve colour performance on the 50 and kitlens? thx
Hi Cross-lane,
I have not used the Sony Zeiss t* filters so cannot comment, but I cannot imagine that they would be at all poor in quality. I think they will be fine- if a touch pricey! I personally wouldn't use more than one filter at a time, it will effect the IQ and will increase the likelihood of flare.
Cheers
