Hey all, I joined this forum quite some time ago when I bought my first DSLR and I am finally exploring the real potential that it has. I have been using Aperture Priority mode a lot lately to really get that down, but one thing has me stumped. I own two lenses, an 18-55mm 3.5-5.6 and a 55-200mm 4-5.6 that I have been experimenting with. I have found that although the 18-55 has a lower minimum aperture, I cannot get nearly as good portrait shots as when I am using the 55-200 and standing further away and zooming into my target. Can anyone explain why this would be?
