After posting a few times about covering a wedding, a lot of people have recommended a lens with a low f stop, should help with low light etc. I notice a very common and popular lens is the Canon 50mm primes, but with a couple of options, i wasnt sure what would be best. At the moment im seeing: Canon EF 50mm f/1.8 II Lens for about £60 Canon EF 50mm f/1.4 USM for about £220 As much as id love the L, way out of my budget, but whats the main difference between these two. Is 4x the price, 4x the lens? Or have you any other surrgestions for lenses in low light. A budget applies, if its something ill find myslef using again, i can spend a bit more, or for the odd wedding will a £60 get me by?
