New Sigma 30mm F1.4 DC HSM - Guest - 01-29-2013 New 30mm F1.4 DC HSM by Sigma has a very different optical design with front element much smaller. Looks like a simplified version of their latest FF 35 F1.4: http://www.sigma-global.com/en/lenses/cas/product/art/a_30_14/features.html Old 30/1.4: New 30/1.4: FF 35/1.4: MTF time!

APS-C to MFT image circle reduction still works and would make a 42mm equiv f/1.0. I'm not too fond of 50mm equiv. Greetings, S. |
