Olympus user and proud of it - born to be different!
I use Olympus DSLR cameras for their small lightweight size and ease of use. With a range of features, the ability to carry two camera bodies and lenses in a small rucsac helps ensure that I'm ready for many photo opportunities. And when without the Olympus DSLR a small compact Canon Ixus is usually to-hand.
My original Olympus E500 was replaced with the Olympus E520, which is an excellent value for money camera with access to some excellent lens, and more recently the kit has been updated further with a bargain E-30 from Jessops.
The smaller sensor size can mean more noise at higher ISO settings (400 upwards), but it also means that the focal length of four thirds lenses are doubled up - so the really good value 70-300mm ED lens is the 35mm film camera equivalent of a 140-600mm telephoto lens.
In late 2008 a combination of the Olympus E-520 + ED 14-42mm f/3.5-5.6 + ED 70-300mm f/4.0-5.6 cost less than the camera body only of a Nikon D300 * - now that really was a good way to get into longer range photography!
Olympus though have always had a struggle in the DSLR field against the might and name of Canon and Nikon. A larger sensor in these makes and a constant range of good quality cameras from beginner standard right up to the demanding Pro photographer, has always ensured that these brands are a 'safe bet'. But makers such as Olympus have produced some cameras that challenge the norm and bring in new features that eventually get adopted by the big two.
But there is no doubt that it is a commercial struggle - shops tend to rely on displying Canon/Nikon and only have very limited stock if any at all of smaller brands such as Olympus, and consumers therefore have reduced choice so therefore will tend to buy Canon/Nikon - it's a vicious circle that is hard to break into.
Recent months therefore have seen a perceived reduction in Olympus support of the DSLR market with only one new model being released. This is the top of the range E-5 - see http://www.olympus-europa.com/consumer/dslr_digital-slr_e-5_23432.htm#/reliability/ - but below it the supporting camera range is being reduced and not replaced.
The massive area of expansion for Olympus in the last few years has been in the 'micro four thirds' system -this really has been a commercial success for Olympus and the early adopters.
It is what they call the 'new generation' PEN system, which uses a smaller sensor than the standard four thirds sensor thus enabling the camera body to be smaller. This is then combined with smaller lenses to create a lightweight small camera system. Think of it though as an enhanced compact digital camera with far more flexibility of control but with added bulk! See http://www.olympus-europa.com/consumer/pen.htm?_s_icmp=PEN_Websp_button
I still prefer to have a properly small compact digital camera in my pocket and a bigger digital SLR camera. The answer for me though arrived in early 2011 with the announcement of a new semi-pro compact digital camera from Olympus - the Olympus XZ-1 - this keeps the size very small, has a reasonable sized sensor, and really will fit in the pocket without too much trouble.
See http://www.olympus-europa.com/consumer/xz-1/digital-camera-XZ-1-manual-control.htm - I look forwad to being able to evaluate it.
