What camera system do you shoot? Why?
I am a Pentax man, and I will defend them to the end. I shoot a Pentax K-5, I recently upgraded from the K-r. In addition to the kit 18-55mm lens I have a Pentax 40mm f2.8 ltd and a cheap 28-300mm Sigma.
1. Pentax DSLRs have unparalleled high ISO performance.
2. LEns compatibility is really wide. Any k-mount lens even ones form the 70's will attach and work.
3. In body stabilization means any k-mount lens is image stabilized.
4. The K-5 is the best bang for the buck with it comes to image quality and build quality.
But then again.., I am bias. How about you?
