Compatible Lenses with a Sony a55
I'm quite new to the photography scene, and have been looking for some additional lenses for my Sony a55. I currently have the lense bought with my camera which is a '3.5-5.6/18-55 SAM lense' and I am on the look out for a lense with better zoom and sharpness, but have no idea where to start..
Some tips on what type of lenses I should look for would be appreciated! I don't want to spend ridiculous amounts of money, but I want to be able to take better quality pictures
Thanks in advance
