50F14 or 50M28
I'm looking at getting a low f-stop lens for my alpha, and I'm wondering if someone can tell me the biggest difference between these two lenses. there is the SAL50F14 which has an fstop of 1.4 or the SAL50M28 which has an F of 2.8 but does macro.
what makes a lens be able to do macro? the focal difference is .2 meters vs. .45 meters. i want to be able to do macro but is 2.8 going to be large enough for doing shots in dim lighting?
based on price i'm tempted for the 50F14, but i'm wondering if i should save my pennies for a little longer and go with the macro.
I will have to get the lens from sony, otherwise i would be all about getting something used!
