I am interested in any opinions on low-light concert photography.
I am moving from crop-sensor to full-frame and kit type lens to either primes or f/2.8 zooms.
I am considering D610 with both the Tamron SP 24-70mm f/2.8 Di VC USD and the Tamron 70-200 f/2.8 Di VC USD.
The venues I am interested in vary from intimate (5-20'), medium (15-40'), to larger theater (40-60').
I figure I would be gaining 2-stops on the camera and anywhere from 1/2 - 2 stops on the lens depending on focal length.
Suggestions on camera, lenses, tips and how to find a reputable dealer who sells for something less than list price would be greatly appreciated.
