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.

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.

Small, lightweight, and razor sharp

Got this lens for some headshots at work (and well, I do love primes!) and have not been at all disappointed. The focus is quick, and the images are very sharp. Got a good deal on it in the refurb store to save a bit of money. This one will get a lot of use!

Excellent portrait lens with stunning sharpness, contrast, and background blurring capabilities

I use this lens with OMD-EM10. This is another very sharp lens. It has a good solid feel. It is middle sized in my holy trinity of prime lenses which includes beside the 45mm, the Olympus 25mm f1.8 and Panasonic 14mm lens. However all three of my prime lenses + my 75-300 with a spare battery fit in my National Geograhic Africa collection small sling bag NG A4567. So while it is bigger than my other prime lenses, it is not huge. Infact it balances really well with the OMD-EM10.

The images this lens produces are stunning. They have very good colour, sharpness, and contrast. Same as the Olympus 25mm f1.8 lens. The focal length is eqivalent to 90mm of film camera. This focal lenght is ideal for portrait photography. It is sharp even wide open at f1.8. I manage to get decent background blur. People go wow when they see their picture taken with this lens.

If you are looking for a prime portrait lens, then go for this lens. It is for sure a very sharp and excellent lens. Highly recommended.

Great lens for the price.

Great for portrait as well as more general use. Nice street lens fast and sharp for the price. You won't be disappointed with it.

This short tele lens is great for 1-2 person head and shoulder portraits. It's relatively low priced, and almost quizzically small for its focal length.

If you haven't been satisfied enough with shallow subject isolation from the kit lenses--particularly at full zoom, this lens will probably fix that.

I beat mine up pretty badly, and it looks terrible, but it keeps shooting great pictures. Sharp wide open, even sharper stopped down a notch or two. Initially I hated using this focal length, but after getting accustomed to shooting close portrait shots, I really warmed up to it, and use it as much as I can. It's a faint bit soft in the corners, but unless you're trying to shoot landscapes at hyperfocal, it's probably not a issue. Color reproduction is of course, great.

Haven't tested it extensively against my new and highly regarded 40-150mm f2.8 pro, but the pro is a bit sharper from what I can tell. Colors seem similar. Quite a feat against that monster of a (m4/3) lens! The 45 is not obsolete by any measure in contrast to that, especially in size.

Highly recommended if you're looking for something in this focal length. Great fun once you get a feeling for it.

What a great little lens!

I've been after a decent focal length with fast aperture for a while now. I did "almost" pay a lot more for a competitive brand and decided to check this 45 mm f1.8 out personally at a local dealer.

Not only is this lens great for portraits or shots requiring the focal length but the bokeh achieved by varying the aperture is quite amazing. I have been keeping it on my camera constantly as the lens of choice over the 17 mm lens that came with the camera.

I took some portrait shots recently and the subject emailed me a little while ago complimenting the work.

The price and performance of this lens is in a league of its own.
