It has fast auto focus, sharp from center to edges.

store.-focusing is a bit slower and needs more high contrast areas for correct focus than other Olympus Primes I own.

Focus is super fast.

The focus is sharp and the field of depth is phenomenal

I bought this to go along with the Olympus OM-D. Very sharp, fast focusing

The focus on my EP-1 is slow, but it's a portrait

Other highlights include being one of the sharpest and fastest focusing lenses on the Micro Four Third systems

It's a great lens: small, fast, bright, fast-focusing, and wicked sharp even when used wide open.

* Very fast focusing lens* Plastic construction but metal

I haveSo far it is pretty impressive, the focus is fast and silent

It is most useful for portraits to get great focus isolation of the subject from background and most importantly, including very, very low light portraits.

The focus is very sharp and the auto-focus speed is fast

It's sharp all the way open, geourgous coloring, and silent focus

I have found the manual focus to be a bit tacky

This lens takes wonderful portraits and is especially good at selective focusing and shallow depth of field, delivering creamy buttery bokeh (blurring of the background).

Fast focusing, checkSmall compact size and well built frame, checkBeautiful bokeh capability with its narrow field of focus

Focus is fast and quiet, like other newer Olympus lenses

Lovely background blur, crisp focus where you want it.

Note that those are older lenses that feels cheap, hardly any focus ring, and not sharp wide open -

It is light weight, fast focusing and produces good quality images

I bought this with the E-PL5 in September 2104.+Outstandingly fast and accurate focus.+I tend to use center weighted metering which has been very accurate+ amazingly sharp and high RESOLUTION

I might have gotten a very early copy of the black lens since some issues were noted.-when initially attached to my OM-D, the aperture blades were going crazy while focusing; similar to what happens when you attach a Panasonic lens to an Olympus body.

Crystal sharp focus and gently soft out of focus

It's made in China but the lens feels solid enough with a metal mount and good focus ring

It would be nice if it had a better minimum focus distance

Great bokeh and fast focus - and just overall nice pictures

I guess the lens mimics the human eye, kind of blurring in and around the subject but having a sharp focus on the subject

Lovely background blur, crisp focus where you want it.

Manual focus works very well on it too.

Along with taking razor sharp images the focusing of the Olympus 45mm is very fast and nearly silent

45mm f/1.8 clearly outperformed the Nikon f/1.4 at the lower apertures

Put this lens on an Olympus OM-D or Panasonic G3 or GH2, and your images will beat the pants off mid-level APS-C DSLRs and, hard to believe, go toe to toe with the last-generation full frame DSLRs (i.e. the Canon 5d Mk2).
