CRX-5 Ultra Low Foot/Plate
Perfect for the SONY 400mm/f2.8 and the SONY 600mm/f4 lenses
John and Walter Zeiss at 4th GD took their time and came up with a masterpiece. You get to choose where the foot lines up from one of 6 set positions. The design is elegant, clever, and deadly efficient. The lightweight CRX-5 is somewhat of a hybrid lens foot/lens plate as there is enough room between the plate and the lens so that you can carry the lens by the foot without pinching your fingers. Best of all, assembly was way-easy. I did it myself with barely a glance at the instruction sheet.
