That said, the 35/1.4 is better for someone who is using different formats. Though there are anecdotal reports of the 30/1.4 A being pretty much workable on FF (though, of course, nobody would expect good results in sharpness/vignetting department). Heck... I may even have a request in this regard: when the 30/1.4 A comes your way, try to test it on FF as well (if only to assess the vignetting, I have no right to demand a full review).
