My work is landscapes and some abstract IR, all b/w. I am in the market for a good 20mm lens.
for full frame Nikon.
After spending way too much time reading reviews, I am struck by the huge differences. I don't usually rely on users that simply add their opinions, instead being more likely to accept a technical review, such Diglloyd or Dxo Mark, for example.
On reviewing the Sigma 20mm f1.8 DG lens, I was struck by their rating of this lens within one rating point of the Zeiss 15mm f2.8. The price differential is roughly $600/$3000!!
Taking into consideration that the wider 15mm will get a lower vignetting etc rating simply due the the wider focal length, I find the rating nothing short of amazing.
If you go to, say Fred Miranda's site, which has a lot of guys giving their opinions, they rate the Zeiss at a perfect 10,
and the Sigma 20 at 7.8.
Am I missing something here?? (I own the Zeiss 15, find it excellent)
