Olympus's compact entry Four Thirds DSLR — the E-450, 10MP, pentamirror, 2009.
The Olympus E-450 was released in 2009 as a compact entry-level Four Thirds DSLR, a small update to the earlier E-420 and one of the smallest and lightest DSLR bodies of its time. It was aimed at beginners and students moving up from compacts into interchangeable lenses.
The E-450 is a Four Thirds digital SLR with a 10-megapixel Live MOS sensor in the four-thirds format and a Four Thirds lens mount. It has an optical pentamirror viewfinder, Live View on a fixed rear screen, and in-camera Art Filters, but it does not have in-body stabilisation and has no video recording. The shutter is a focal-plane type.
Paired with the slim Zuiko Digital pancake lenses it makes a genuinely pocketable DSLR kit that suits travel and everyday photography for beginners. The 10MP sensor is fine for prints and screen use in good light, though the lack of in-body stabilisation and the smaller sensor mean it is less forgiving in low light than stabilised or larger-sensor rivals.
When buying, check the shutter count, inspect the sensor for dust and dead pixels, and test the fixed rear screen and Live View. Confirm the card-door and battery-door latches and that the compact BLS-1 battery is still available. Its Live MOS colour is clean for the era, but as an entry E-System body it lacks weather sealing, and note that Olympus has ended service for these cameras, so buy on tested condition.
