$120 · Olympus HLD-7 Battery Grip for OMD-EM1 Mk I DSLR camera

The HLD-7 Battery Grip from Olympus is designed for use with the OM-D E-M1 Micro Four Thirds digital camera. With one battery in the grip and another in the camera, you can capture approximately 680 shots per charge. The HLD-7 features a shutter release, two control dials and two function buttons for shooting vertically, in order to afford the same ease of operation you enjoy when shooting in horizontal position. Its dust- and splash-proof design also complements the weather resistant construction of the E-M1 for shooting in inclement conditions. This grip is in brand new condition, adds little bulk to the MFT camera and offers extended shooting times in the field without swapping batteries, with additional controls ergonomically placed. Retail price is 250 plus tax so you would be getting it for less than half price. Note this grip does not fit on MkII or MkIII models of the EM1; but if you have a MkI, this is a deal for you.
