The Olympus E-450 is a 10 megapixel digital single-lens reflex (DSLR) camera
made by Olympus
and conforming to the Four Thirds System
standard. E-450 was announced in March 2009, and shipping started in May the same year. E-450 is similar in size to its siblings in the E-4XX series, marketed as the smallest DSLRs in the world.

- Three Art Filters, where the camera processes the image to give it a new appearance. The filters available in E-450 are Pop Art, giving the image a very saturated look, Soft Focus making the images look "dreamy" similar to the effect of a diffusion filterDiffusion filterA diffusion filter is a translucent photographic filter used for a special effect. When used in front of the camera lens, a diffusion filter softens subjects and generates a dreamy haze. This can also be improvised by smearing petroleum jelly on a UV filter or shooting through a nylon stocking...
