About 47 years ago, Olympus went out on a limb to introduce a half-frame camera that featured interchangeable lenses and an image that measured 18x24mm rather than the movie film-derived 36x24mm film size. We are beyond film at this point, favoring digital image capture instead, but Olympus is still holding fast to its legacy, with their new, impossibly compact, E-PL1 interchangeable lens camera (ILC). At $600 with a lens, it may be both one of the cheapest and the smallest ways to get into serious photography ñ weíll find out in our review if itís the best.
