Sure bo, Bro? 43 more reliable in low light? Got such things 1 ah :bigeyes:? ... I got 43 b4 and I know it's much 'better' than the 50 at 1.4 ... :blah:
I owned both for a while, and let go the 50mm, becease it is not as **** eyed .. as 50mm f1.4 - even in Program mode. it works magic on CCD sensor than Cmos, a bit of regret letting out really cheap, but with my LBA on all the time, I was abit anxious of the 55mm f1.4 strike me I don't know what will I get next, I dreamed of the Tamron version (if they have one)90mm never fail me in any condiions.
