Hello, I have a quick question regarding the XT-2. I jumped from a Canon 40D to the XT-2 some time ago. I love the camera and the feel and output are fantastic for me. With that said, I have noticed that I have a harder time (on the Fuji) transferring what I see in my viewfinder to my computer screen. In other words there seems to be a disconnect between what I see in the computer and what I remember being in the viewfinder. I don't think it is a color or exposure issue, maybe a framing? Not quite sure. Do I simply need more experience with the camera? I'm using a 18-55 for both cameras. Thank you.
