Ok so I have to ask how you are taking these photos? I assume tripod, no pumps on, cleaned glass etc.
But what settings are you using on the camera (and what setting on the dial, shutter speeds, aperture size, etc) since I have the same model. Also are you shooting in RAW format and editing the color in photoshop?
I'd just like to get somewher near the clarity and light levels in your photos!
