Olympus has announced a new promotion for the E-3 DSLR, and is offering all purchasers of the camera one of five free products.

The "Rev Up Your System" promotion offers anyone purchasing an E-3 between 1 January and 31 March and registering it online before the end of April a free E-3 accessory by way of a thank you.

Photographers can choose between the five products available as to which they would prefer to receive.

First up is the Zuiko Digital ED 9-19mm 1:4.0-5.6, a Four Thirds-based wide-angle lens that boasts 100° angle of view. There is also the Zuiko Digital ED 50mm 1:2.0 Macro lens available, which delivers life size magnification.

The Zuiko Digital 25mm 1:2.8 pancake lens is the last lens in the freebies, and also comes with the new Olympus Swing Back and the FL-36R Flash.

If you have all the lenses you need but are just looking for a good wireless flash, the FL-50R is the fourth choice in the freebie list, boasting multiple adjustment modes.

The SRF-11 Ring Flash Set including FR-1 Adapter Ring rounds off the free goods, and rings in at the most expensive free choice going should that sort of thing sway your decision.
