I just got my new lens in finally and I really love it. I thought it was going to snap right off my camera when I mounted it the first time, it's pretty darn big compared to my 50. However, I was having a little trouble getting my photos sharp in studio. I will admit I was pretty shaky when attempting off the tripod shots. Here is a photo taken while my son was playing outside. I over sharpened it a bit, purely for web showcasing purposes. DSC_3438_edited-4 by Lily Belle Photos, on Flickr And here is one I tried in studio. This is my son's "are you kidding me" face. DSC_3561_edited-2 by Lily Belle Photos, on Flickr I think my trouble with the softness on my studio portraits is the fact that there was too little light. I only used the modeling lamp on my Alienbee. Could that be a reason why they were coming out a little soft? Could I leave a lamp on (to get more light and allow my camera to AF correctly) without ruining the pictures? Any tips and tricks would be appreciated.
