Hello all! Very new to this forum but so glad I stumbled upon it! I am merely a mom who enjoys taking pictures...mostly of my children and childrens' sporting events. I have the Canon Rebel XSi with the EF-S 18-55mm 1:3.5-5.6 IS lens. This lens suits everything I do, nicely but I would love a prime lens. I have been doing a small bit of research and I believe the lens I am looking for is the Canon EF 50mm f/1.4. Only problem with that is my budget I'm looking to stay below $200. Are there any options out there for me? I have seen a similar lens but it was a 52mm filter length, whereas I have a 58mm. Is there such a thing that would allow me to use the 52mm? An attachement perhaps? Maybe an off-brand as opposed to Canon? Sorry if any of this seems elementary, but I am teaching myself how to take pictures, learning to only shoot in AV mode. I have a friend that does take pictures professionally but uses a Nikkon. She can't help me with my Canon. Thanks in advance for your help! Angela C.
