It seems to outperform all other wide AF primes... Lenstip is really understating the value of having a lens that as sharp at the edges as at the center.
I think it was the polish language version that had been out, I hadn't seen the english version yet, though I could be mistaken.That review has already been discussed some time ago IIRC (or was it another forum), including the tendency for Lenstip to test well but summarise poorly. Quote their summaries (and believe them) at your peril.
My mistake, it was another forum. But here are a couple of more interesting comments from that other thread, IMO:That review has already been discussed some time ago IIRC (or was it another forum)...
Lenstip's highest MTF score for the Sigma 35mm/1.4 lens is 47 lp/mm on a Canon 1DsIII which is a 21MP camera. The highest MTF 50 score for the Panasonic 15mm/1.7 lens is 70 lp/mm on a 12 MP camera, EP1. If you convert these to LP/PH and account for the fact that the 35mm lens was tested on a 21MP body there is no difference in the MTF scores between the two.
