This single-focal-length portrait lens has a beautiful shallow depth of field which allows for background blurring effects that are not possible with the 14-42mm kit zoom lens. The Movie-Still-Compatible (MSC) mechanism utilizes nearly "silent" focusing technology. It is great for tracking a moving child or pet, and provides a quick and silent focus mechanism for movies and still photography.

My Favorite Lens Right Now

This is my favorite lens right now! Super fast and razor sharp! The photos are beautiful and I could not be a happier customer with this purchase. This lens gets tremendous work during family photo shoots, and the results really show compared to other non-portrait lenses. This lens really can separate the subject at the lowest f 1.8, and the sharpness is quite good. The lens can be used at f 1.8 quite often due to the inherent sharpness present. A must have for prime lens professionals.

Outstanding lens, decent build quality

The 45mm 1.8 is a wonderful, compact, short telephoto lens. In my experience, it is sharp starting right from f/1.8, focuses relatively quickly, and produces beautiful results. The 1.8 aperture really comes in handy when isolating the subject from the background, especially in portraits. An amazing lens!

The build quality is good - not the great solid metal construction like some of the other lenses in the system, but a good plastic housing. It would also be great if it came with the lens hood instead of having it be separate.

My only gripes with the lens are the 37mm filter size - most of my other lenses take 46mm filters, so it makes it harder to share between them.

Allmost perfect little lens

This lens is very light and feel an touch is plastic. At least the lens mount is metal.
It also doesn't have the 'Manual' focus ring which is a pity.
It's also a pity that this lens does not come with a lens hood.
Anyhow once you have this little one one your camera you might not want to remove it.
Very nice for portrait work - sharp at 1.8 with a decent bokeh.
Fast Autofocus with only little hunting in low light and only very few out-of-focus pics.

awesome portrait lens!

I have been using this lens for the past few months and it has become my most favorite portrait lens! The sharpness is amazing and provides the perfect amount of compression at 45mm (90mm equivalent). Don't let the small size fool you as the lens produces amazing photos. I love opening a photo in Photoshop, zooming all the way in and seeing all the details that it has captured. I never leave the house without this lens! Must have!

Best Lens I Own

I have been using this for a portrait class in college, and have gotten amazing quality work with this lens. My professor in art photography even asked, "What lens is this? I really need to buy it." The quality is just too good compared to the rest of my kit. If that doesn't convince you that you need this lens, I'm not sure what will. I continuously reach for this lens and find myself switching back to it over lenses with better range, etc., even over other cameras that I own.

Perfect Portrait

This is my favorite lens of all my micro four thirds. This lens gets tremendous work during family gatherings, and the results really show compared to other non-portrait lenses, and obviously compared to run of the mill point and shoots. This lens really can separate the subject at the lowest f 1.8, and the sharpness is quite good. The lens can be used at f 1.8 quite often due to the inherent sharpness present.

It's really an amazing little thing, does what's expected from.
I'm using this lense with olympus air a01 and it's doing a great job.
I took a really nice photos with it.
I like the size, weight and quality of the photos.
The auto focus is really fast.
I use it almost for everything.
I think it's a MUST have lense for a 4/3 cameras.

Great short telephoto and useful for throwing the background out of focus of one or two person portrait photos. One star off since the autofocus can sometimes not lock in after initial start up. Just use manual focus to bring some contrasting edges into the frame and the autofocus will be able to pick it up from there. I keep this lens with me just about all the time.

Great portrait and street lens

Is it as good as the 75mm f/1.8? Nope, but it's close and, for the price, it's a terrific medium tele lens for portraits and street work. Light and quite sharp it's on a par with the 25 f/1.8 in price, size and IQ.

A great portrait lens

It is simply the best portrait lens I've ever used. I love the bokeh, sharpness, and autofocus speed.
