DigiCamReview reviews the Olympus E-420: “The Olympus E-420 is touted as the “world’s smallest digital SLR” and there is no doubt the camera is compact and light – mounting the 25mm lens and ready to shoot with a CF card onboard, my review unit weighed in at just under 18.5 ounces. As DCR.com editor David Rasnake mentioned in his First Thoughts piece on this camera, with the 25mm lens onboard in particular, the Olympus E-420 is approaching mid-size ultrazoom territory: 5 x 3.5 x 3.75 inches, versus the Canon S5 IS at 4.6 x 3.15 x 3.06 inches and about 18 ounces. To be fair to the Canon, it does pack a zoom lens featuring a 36-432mm focal length range, while the Olympus E-420 is stuck at an equivalent 50mm, but it’s still a fairly dramatic example of just how small a full-featured DSLR can be.

I personally found the Olympus E-420 a bit small for my hands, and the placement of the strap attachment eyelet and ring near the shutter button rubbed my middle finger the wrong way. The Olympus E-420 also had some difficulty acquiring focus in dim light on occasion – perhaps not out of the norm for entry level units, but annoying none the less. All in all, though, there’s not much to gripe about on this otherwise capable entry level unit.”
