Hello guys! here again to ask for help to those who can! I'm looking into purchasing a 2nd hand Sigma 30mm 1.4 HSM, and I've got a question for you guys regarding the 'wideness' of the lens. I already have a 50mm 1.8 but I wanted something wider that is within reach of my pocket! and i came across the 30mm in another forum. do you guys have comparative shots that used the 30mm and the 50mm? I mean if you guys have picture/s taken by the both lens from the same distance? i'm really after the wideness so that I can use it in parties that are a bit short on space...i was thinking of getting the 17-50 by Tamron but as of the moment, it's out of my pocket's reach! you're help is highly appreciated! thanks in advance!
