I have been debating whether to go to FF or APSC sensor size due to DOF and low light performance of them. This lens I bought used through Amazon (seriously like new at 2/3 price). The result I love so much that I am keeping my MFT system.

A wonderful lens. Together with the Nocticron by far the best m43 prime. Better than the 25 f1.2. Cannot be replaced by, for example, a 40-150 f2.8 Pro, as the Bokeh is lightyears better. If you have the money, buy it. You will never regret.

Optically close to perfection; Beautiful colors; Just perfect, not over-saturated; Relatively small and unobtrousive; Ideal for stealth portraits; Wonderful mild and smooth bokeh, One of the best I have ever seen

AF could be faster; Focal length in some situations a tad too long (not the fault of the lens); Lens hood not included and sold by Olympus for an obscene price; I bought the generic hood from JJC for half of the price; Perfect match

I've taken the best photos in the last 5 years in the last two weeks I've had this lens. Sharp edge to edge wide open this thing is awesome. Perfect portrait lens if you have enough room. Built like a tank this thing is solid. Buy it or buy the kit with the 45mm.

Its price is pretty reasonable among the store I have viewed. It worked... For a week. Not the quality I was looking for. not very pretty, but they have plenty of use Five Stars does exactly as intened

A wonderful lens that is tack sharp, creamy bokeh and the perfect focal length for outside portraiture. I love walking and taking photos of my two children, this lens is perfect for this as you need a little distance between your subject and the camera in order to make the most of it.

This lens is amazing. Although large for an m43 prime, it's still astonishingly compact for a 150mm equivalent lens. Compare it to a full frame long prime and it's no contest. On top of that, it's blisteringly sharp starting from f/1.8, and is actually one of my fastest focusing lenses.

Will deliver excellent shots in nearly all circumstances. Aperture controls the DOF and leaves everything else unaffected. I do know a slightly better lens (the Zeiss 135/2 APO) but that one is for DSLRs. From that point of view, I won't even call it expensive.

Optically close to perfection; Excellent IQ

None

Simply put, we're big fans of this lens. Having used it with a variety of Micro Four Thirds cameras over the years, from the pro-grade Panasonic Lumix GH4 to the cheap-and-cheerful Olympus PEN E-PM2 , we're confident in proclaiming it one of the best in the system.

Great metal construction; Feels very well made; Extremely sharp

Distance readings and MF switch / choke would make this even better

I have resisted buying this lens for so long, then Wex's 10% off deal came along and I could not resist any longer. It is the most incredible lens I have ever owned, build quality is superb, it's solid, very compact, with smooth manual focus ring.

Durable; Great Picture Quality; Lightweight; Metal Construction
