Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED review by Lightweaver
Review Date: 5/4/2015 Would you recommend the product? Yes | Total Spent: $799.00| Rating: 10 

Pros: Fast, well built, close focusing, weather resistant, sharp.
Cons: EDIT: Thought of one. The auto manual clutched focus ring can be a little loose. Easy to bump it from auto focus to mechanical manual focus. Minor issue but I've done it a few times. Would be nice if it was a little stiffer to pull back.

This is the second best lens I have owned in almost 50 years of photography. The best is its companion 40-150 F2.8 Pro lens. A little larger and heavier then some m4/3 lenses but not so much as to be a problem for me. Optical quality is great at all focal lengths from F2.8 through F8.0. minimal distortion. Excellent micro-contrast and detail rendition. Close focus so good it is almost macro, at all focal lengths. This is my most used lens and never lets me down. (Waiting on the new 7-14 ultrawide pro zoom though). Prime lens quality in a zoom lens. Can't say enough about it when used with my OM-D E-M5 Mark II. NOTE: Price was price when bought with a camera body. ($200 discount)

Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED review by lightknight
Review Date: 4/20/2014 Would you recommend the product? Yes | Total Spent: $900.00| Rating: 9 

Pros: Build, acuity, range, quality feel, nearby bokeh, close focussing
Cons: distant Bokeh

This lens successfully out resolves the sensor on my OMD M1. The build quality is on a different level to many other 4/3 lenses and is a pleasure to use.
Being realistic I cant give the lens a 10 as its probably not as sharp as, say the 75/f1.8 but for a zoom it is outstanding. The only issue is distant bokeh, where the "real" F2.8 becomes an effective F5.6 and it can look very busy compared to my FX. Interestingly, out of focus areas in the near fore and background look great. The fact is this is a great landscape lens where DOF is important, it focuses as close as 150mm from the lens and is certainly good enough for a quick portrait against neutral backgrounds. Spending $900 doesn't get better than this.

Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED review by azoele
Review Date: 2/5/2014 Would you recommend the product? Yes | Total Spent: None indicated| Rating: 9 

Pros: Sharpness, bokeh (when you get it...), fast autofocus, colour
Cons: 2.8 is quite slow on m4/3s

The lens is a real surprise: very fast to autofocus, and very, very sharp. Colours are pleasing and saturated, and the out of focus areas tend to be gentle, not harsh.
Optically, a real winner, and one of the very few lenses I dare use wide open with nary a thought.

The only negative is the speed: f2.8 might seem fast, but on the m4/3s format it is indeed a pretty limiting factor, as it forces you to raise your iso quickly as light gets dimmer, and makes it difficult to get much out of focus (or any at all...) unless you're shooting very near subjects.

An impressive little lens.

Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED review by dglynos
Review Date: 12/21/2013 Would you recommend the product? Yes | Total Spent: $955.00| Rating: 10 

Pros: Triple proof contraction, Sharpness & microcontrast, Excellent optics, 20cm near focus distance, Manual focus ring
Cons: Size & weigh

This lens becomes the defining do-it-all-and-anywhere for any m4/3 system. Optically, this is one of the best zoom lenses I’ve ever used. Minimal CA at all apertures & smooth bokeh. It can replace a couple of primes quite easily, especially the Olympus 12mm f/2.0. Perfect travel pairing for my E-M5 (with the top part of the HLD-6 Battery Grip attached for better handling).

Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED review by rrwilliams64
Review Date: 12/19/2013 Would you recommend the product? Yes | Total Spent: $999.00| Rating: 10 

Pros: Build quality, optics, handling
Cons: none

In reality, imagine having the equivalent of the Canon 24-70 f/2.8 L at basically less than half the price. That's where the MFT format's latest pro lens from Olympus leads us. Top notch build quality, tack sharp wide open, beautiful color rendition. Not to mention being weather resistant, along with easy clutch mechanism to switch from AF/MF. Having been a long time user of both Canon and Nikon, I've switched to the OM-D E-M1 with this glass and haven't looked back. Not cheap, but taken in perspective to pro glass prices from the big two, it's a bargain. Highly recommended.

Pros: Wow what a lens in that package
Cons: Nothing

If you had a place higher I woud give this a 12-15. Sensational lens,and I was a sceptic about the 4/3 format. Went out with it first day to shoot anthing in our area and edge and center were so sharp. Great color and bokeh. All of the reviews do not say how great.

Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED review by Prime Minister
Review Date: 11/16/2013 Would you recommend the product? Yes | Total Spent: $1,200.00| Rating: 10 

Pros: Sharpness, contrast, autofocus, weather sealing, construction, close focussing
Cons: Size, weight

There's really not much to say about this zoomlens. It's a great performer at all apertures and at every focal length. If you pixel peep, you'll find that it's a tad softer in the corners when zoomed past 25mm, but that's about it. I can't imagine this to be a problem in real life. If it is a problem, just set the aperture to f/4 to get photos that are evenly sharp from corner to corner. CA and distortion are both very low and the bokeh is okay for this type of lens. Most of the time it's not creamy smooth, but it's not harsh either.

I thought the Panasonic 12-35mm f/2.8 was good, and it is, but I like this Olympus even better. It has less distortion and CA and it's sharper on the wide end. It seems to me that this lens gives a more consistent output then the Panasonic f/2.8 zoom. The biggest surprise may be that it comes with a lens hood.

Focussing is quick and silent. Zooming is smooth, but my copy does emit a strange faint rubbery squeaking sound when the camera (E-M5) is turned on. When the camera is powered down, the sound disappears. I have absolutely no idea what it can be. Maybe some small electronic motors that start moving while zooming the lens in and out. Anyway, it's no big deal.

You can get really close with this lens. I think it's a very nice option to have and I can imagine that many photographers don't need an extra macro lens. This Olympus 12-40mm might very well be the only lens many people ever need. Especially when combined with the very efficient Olympus in body stabilization. It's a do it all kind of lens. And it does it well too.

The build quality is really good. Just like the Panasonic 12-35mm f/2.8. The Olympus is bigger and slightly heavier though. For a 24-70 f/2.8 equivalent it's pretty small of course. This is a lens that really makes me wonder if I should keep the Olympus 12mm f/2. The prime is slightly sharper in the center, but I doubt it will be visible in real world photography. I'm under the impression that the zoom is sharper in the corners, impressive!

I think the Olympus 12-40mm f/2.8 Pro is a great lens and definitively worth it's somewhat hefty price tag. Anyway, in my opinion it lives up to its 'Pro' label.
