Olympus M.Zuiko Digital 17mm f/1.8

It is everything they say it is. The Olympus 17mm 1.8 has been reviewed a million times. It is everything they say it is. Very sharp. Image quality is excellent. Small but mighty. Most of the micro 4/3 prime lenses are plastic and very light. This lens is metallic and not real light but not real heavy. When you pick it up, it feels of quality and great engineering. The manual focus ring is buttery smooth with stops of all things! And the Olympus system of snapping the ring back towards the camera to initiate manual focus even if the camera is set at Auto Focus is fantastic. Auto Focus is fast. Really fast. Never miss a shot with this lens. It is very quiet in auto focus. Cannot hear it at all. This lens is actual 34mm at full frame measurements. Boca is what you would expect from a 4/3 camera lens and camera. Not incredible but not objectionable. This is not a macro lens. It can take close up shots but the 30 mm lens is way better for macro work. Or if you are into bugs, then the 60 mm is the way to go.t Image quality is excellent. I am using an Olympus OM-D EM 5 II and so far, this lens gives the best quality images on it. While other lenses are really good, this one is even better. Don't think too long about getting this. Just get it and enjoy the images that this lens and your camera can produce. Read full review

Good lens, but expensive = medium value It's compact, the construction is great. The rear element is big and the front element is small, which makes it look wimpy. But if you can get over that and you like the 35 mm (eq.) focal length, you'll love this lens. I use it to take family and party pix indoors without flash on my E-M10 III, and they come out great. Before this, I tried a Panasonic 20/1.7, and it was great too, but a LOT slower to focus and just not quite wide enough. Less expensive and razor sharp, though. Maybe a bit sharper than this one, but you'd be hard-pressed to tell in real-world applications.

Gem of a lens Beautiful, all-metal lens. Quite tiny. Feels almost like a fine watch. Focus ring clutch works perfectly although there is a known bug in the lens (not the seller's fault) that causes it not to interact with the body in manual mode as you would fully expect. 17mm (equivalent to 34mm in full-frame) is a perfect general-user focal length.
