So after weeks of deciding do I leave Canon and switch to Nikon I have decided to stay with Canon. I took some test shots earlier today and at 12,000 iso I was pretty blown away. I plan on doing some test shots shortly and will share them later tonight. I also have to say I have seen the light when it comes to why some folks prefer to stick with L series glass. My intention was to sell the kit lens as soon as I came home. Now I fear that I may sell my Tamron 24-70 to justify keeping the 24-105 that came with the camera.
