Hi there, new to this forum and the SLR photography world. I'm getting my new DSLR soon and choosing lenses too. I've decided to get (amongst others) a 50mm prime lens as I will be taking a lot of portrait photos around the house (my dogs!) and like the look of the photos the 50mm takes. What I need advice about is whether to go for the f/1.8 or f/1.4? How much better would the f/1.4 photos be? Is the difference good enough to justify spending the money on? ( where I'm looking it's about £100 more). I am new to this, but I don't want to go for the cheaper one only to move on to the f/1.4 lens in a few months and ultimately spend more money. Would you recommend going straight to the f/1.4? Worth the money? Let me know what you think.
