Olympus are offering an interesting deal on two digital SLRs at the moment in the form of the Olympus E-30 and the Olympus E-620.

Both cameras are pretty high-end, the E-620 retailing at around £500 and E-30 £600, but if you're in the market you can now get bonus equipment for free.

Coming with the E-620 is a li-ion rechargeable battery (BLS-1) worth around £60 which will go nicely with its now standard power grip, and with the E-30 you'll get a choice of a free power grip worth around £200 or alternatively a FL-36R wireless flash normally £289.

For those who have adopted the E-system already, Olympus are also offering cashback on selected lenses, in order to claim these offers, simply buy a featured product and register online before the end of January.
