Hi i am new to lense and would like to know the meaning of those short term like EFs EFIS and why some so small mm and some high mm
what i know is higher mm like 200mm is a zoom lense and some can go as little as 8mm? marco? or wide angel??
i am totally blur abt lense short cut. I also need to know how to see which lens come with IS and which is wide angel and which is marco.
so any kind ppl out there can explain all the terms? and also the mm , or F-stop.
smaller number of F stop gets bigger opening and higher number of F stop get smaller opening? correct me if i m wrong thanks~
