Roger at Lens Rentals has been testing a few 35mm lenses, and the new Tamron 35mm is the best of the bunch - if you like MTF charts. Actually I have heard that the lens renders rather beautifully too.
I'm one of those guys who'd never touch a third party lens with a barge pole, until that is a couple of years ago I decided to have a punt on the Tamron 45/1.8 as the lens appeared to be exactly what I wanted and Canon didn't make it, despite having patented an almost identical optical formula a few years before.

Incidentally both the Tamron 45 and 85 are AFMA 0 at all distances on my 5DS bodies - unlike some of my Canon lenses......
Trouble is my EF 35/2 IS is so strong I couldn't really warrant a 1.4, maybe, perhaps..........
