Many here know that for the last 10 years I have done all of my concert photography using Canon gear, mainly the 20D, 5D and 5D II. Several people have commented, either in email or in a post, that they wondered if the K5 would work for my concert work since I sold every piece of my Canon gear.... the answer is yes.
Saturday night I had my first chance to test the K5 as a concert camera and the results are good. I used the K5 and the 18-135 (for versatility) and shot most of the time at ISO 800 and 1600... dim stage lighting forced the higher ISO.
I would say that if I had a zoom with a little more reach and a little faster glass I could have done much better but I am satisfied with the photos below as the K5 is still new to me and I am still learning the camera and its various settings and functions.
Anyway... here is REO Speedwagon performing at Billy Bob's in Fort Worth, Texas.
