A newbie here trying to get into Macro but somehow find it very difficult. Bought the Raynox 250 to use on my 17-50 but there is vignetting even at 50mm. Do i need a zoom lens that has a macro function as well. So far still get any good results out of it...Will it help if i change me lens to Tanrom 28-75 macro?
Thanks for the advise and help.
