I shoot primarily with a Canon 5D Mark II equipped with a Canon 40mm f/2.8. I also have a Tamron 28-105mm f/2.8, a Sigma 70-200mm f/2.8, and a Canon 50mm f/1.8.
By back-up camera is a Canon Rebel Xsi equipped with a Tamron 18-270mm f/3.5-6.3. I also shoot b/w 35mm film with my Canon T90 equipped with a Kiron 24mm f/2.
The Rolleiflex never leaves the studio.
