I have tried to get my head around lens and their differences.
Canon EF18-55 or
Canon EFS 18-55
Does the S series lens mean that their is no crop effect on say 7D
In other words the EFS lens are made for 1.6 crop and you get the 18-55
I'm not sure crop is the correct terminology. I have looked through many sites and cannot find an answer. Cheers Brian
