Want to pair your Olympus with a sophisticated, high-quality lens that’s as versatile as it is sharp? Then meet the OLYMPUS ED 12-40 F/2.8 PRO M4/3 LNS BLK, a lens capable of handling everything from night photography to sports and action to weddings—sometimes, all at once. Depending on the wedding.

Product Highlights

  • Autofocus is a key feature here, and it’s what many of our customers find they enjoy about the Olympus ED 12-40 lens. Not only is its autofocus accurate, but it’s quiet enough to keep the emphasis on the subject rather than the camera itself.
  • Easily interchangeable means you don’t have to make this the sole lens in your repertoire of Olympus lenses, though with the versatility of the Olympus ED 12-40 lens, you may just find that you do it anyway.
  • Excellent focal length gives you plenty of options for choosing subjects ranging from landscapes to up-close people.

It takes an excellent photographer to make a lot out of a bad lens; but when you’re working with this Olympus, even the most casual of photography enthusiasts will find that their pictures look really, really good.


Learn about the OLYMPUS ED 12-40 F/2.8 PRO M4/3 LNS BLK

What can a capable lens handle? The better question might be, what can a lens like the OLYMPUS ED 12-40 F/2.8 PRO M4/3 LNS BLK                not handle? Featuring a maximum aperture of F2.8, a filter at 62mm, and a light 13.4 oz overall weight, this 12-40mm Olympus lens is capable of handling a wide range of scenery and events with consistent output and sophisticated picture design. Compare it to a 12 35 lens, or a 12-35mm Panasonic lens, and you’ll see that the Olympus featured here more than holds its own.

But a lens is more than the sum of its parts: it’s also, well, its parts. You can’t ignore what goes into a lens, after all! To better understand exactly what makes this Olympus ED 12-40 lens so sophisticated, we’ll have to break it down by the technical specifications. Let’s get started.

  • Premium focal length. Good focal length is important in any lens, whether you’re talking about photography or, heck, astronomy. The focal length here is 12-40 mm, as the title suggests, or a 24-80mm (35mm equivalent focal length). That gives you plenty of options for selecting what you can shoot with this camera, as many customers have found that they get plenty of use in landscapes, low lighting situations, night photography, weddings, wildlife, and more. That’s quite an array of options, and the focal length facilitates exactly that kind of versatility.
  • Accessories. Some people think of a lens as an accessory. Nope! A lens is an important part; it should come with its own crucial accessories. This Olympus ED 12-40 lens comes with a lens cap, a lens rear cap, a lens hood, a lens case (with instruction manual) and an Olympus 1 year warranty card, ensuring that you get plenty of use out of your new lens. The whole shebang is one camera-strap short of a full camera kit, which ensures that you’ll look like a professional even when your interest is merely that of an enthusiast.
  • Construction. Nowhere is the actual construction more important than in a lens like the Olympus 12mm-40 mft lens. Here with the Olympus 40-150 there are 14 elements in 9 groups, including an aspherical ED lens, two aspherical lenses, a DSA lens, 2 ED lenses, an HD lens, and 2 HR lenses. This offers high-quality video as well as the crisp, clear shots you would expect from an Olympus lens of this quality. Consult any review of the Olympus 2.8 zoom and you’ll see that the construction here is intricate, and the design effective.
  • Magnification. 0.3x magnification is available here—with the 35mm equivalent max. image magnification of 0.6x. That will give you plenty of options in choosing your subjects, your portraits, your landscapes, and more—all while utilizing the subtle blurring background effect that makes a portrait so effective.
  • Fast and accurate auto-focus. Just ask any of the customers at Adorama and they’ll likely tell you the same: the fast and smooth auto-focus here is one of the chief components that makes the Olympus ED 12-40 lens such an easy piece to work with.

Want more out of your lens? Then you might need a time machine, because at this price point, the OLYMPUS ED 12-40 F/2.8 PRO M4/3 LNS BLK is a premium purchase, and as shrewd a decision as anyone can make here at Adorama.

What a great zoom lens!

This PRO lens from Olympus is weatherproof, razor sharp even wide open, beautifully built, gives gorgeous color rendition and is the perfect fit for the new OMD-EM1 body. I use it in conjunction with the 45mm f1.8 (portraits are great) and the 75mm f1.8 (phenomenal mid-tele). The 35mm equivalent is 24-80 on this lens but it has no weaknesses anywhere in its focal range from f2.8 to f8. I used to be a big-body 35mm APSC and full-frame shooter but my bag would weigh upwards of 45 lbs with bodie...

I used to be a big-body 35mm APSC and full-frame shooter but my bag would weigh upwards of 45 lbs with bodies, lenses and flashes. Now it weighs less than 20 lbs with everything I need and the quality is as good or BETTER than before! I eagerly await the 40-150mm f2.8PRO early in 2014.

Nice Lens


from Santa Rosa, CA  -  Photo Enthusiast

Super fast focus. Good in low light. Excellent build quality. Weather proofing.


This lens finalized my switch to m4/3rds


from Portland, OR  -  Photo Enthusiast

This lens convinced me it was time to sell my Nikon DSLR gear and switch totally to micro 4/3rds. This lens is fast, sharp, and smooth. It's bigger and heaver than the "non-pro" lenses but the performance more than makes up for it.


Love this lens with my EM5 MKII


from Milwaukee, WI  -  Semi-pro Photographer

I used this lens with my original EM5 and was not that impressed. However, with the MKII it really shines. My friends have noted that my photos are much sharper.


The 12-40mm in Action: Examples in Story


from Connecticut, USA  -  Pro Photographer

There are plenty of reviews of this great lens available and I held off quite awhile getting one of my own, but I thought showing the lens in use by a publication might be helpful to show how it did. All the photos in "Waveny's always quietest in the snow", which was done in New Canaan, Conn. and published Feb. 8, were shot with my trusty old E-M5 and the Olympus M.Zuiko 12-40mm f2.8. You can search online on that title in quotes and the article should come up easily. I have fast/ultrafast primes like the Voigtlander f0.95's that I use for low light, indoors at dusk, nighttime cityscapes and so on. I've usually got them along with that same E-M5, which has some mileage but still always gets it done. I've reviewed much of that gear, too. But I got the Olympus M.Zuiko 12-40mm as a lens option to have on the camera for general daylight situations and in the inclement weather that, for one reason or another, I often find myself in. The lens' range, good f2.8 speed, very close focusing, overall excellence and so on obviously are very useful in a "grab and go" situation when you don't know what to expect. It's not pleasant if I have to take some of those primes out in the rain, sleet or whatever — they're tough, but I sure don't want water leaking into them. Working on this story the other day, I was out for awhile in heavier snowfall. I figured a snowstorm was exactly the environment to see how the lens would do. With enough snow whipping around, weatherproofing doesn't matter if the front of the lens is all snowy or wet, so I still did my best to keep the camera and lens shielded. The lens worked great all around, and although I blew off snow with a bulb when I hopped back in the car and inspected/ cleaned it later (take care of your gear and it'll do the same for you), the lens was just fine without being coddled. But it is very nice, and it delivers. It's easy to want to spoil it a bit. As a few quick build quality notes, I find the hood works well forward or in reverse as long as I make sure I've got it threaded in its track properly and it snaps on. I was a little disappointed at first that the inner/front lens barrel and front threads are plastic, but they're sturdy and the materials are well-chosen. Just be careful not to mis-thread any filters you use. Also, thank you, Olympus, for the little but nice touches like the cool front lens cap and handsome lens pouch. The lens arrives in some style with attention paid to details. It's hard to find fault with a lens that's just got all the right stuff and will be useful in a variety of challenging situations. Have a look at the slideshow and article if you'd like to see some real-world examples.


You get what you pay for, and then some!


from Littleton, CO  -  Semi-pro Photographer

No, this lens isn't cheap -- but it's worth every penny. Micro 4/3 owners with pro or enthusiast needs had a long wait to get lenses comparable to the stunning f/2.0 SHG (Super High Grade) 4/3 lenses. This is the first of Olympus's really professional-grade lenses for micro 4/3, and it's a beauty! It's solidly built, weatherproof, optically fast, and can help you take great photographs. The bokeh is nice and smooth, and it covers a very useful range of focal lengths -- put this on your micro 4/3 camera body, and most likely you'll rarely need to swap another lens for it. Of course it's not as cheap as a kit lens -- but in this case you really do get what you pay for (if not more). Buy it, take care of it, and you'll have a great lens for life.


It's beautiful - and expensive.


from Oberlin, OH  -  Pro Photographer

I didn't expect to like this lens as much as I do. It is extremely well designed and well constructed, and the images are indeed great. I chose it primarily for its excellent defocusing ability and am very pleased. Focus speed and accuracy is excellent. But it sure is an expensive lens.


One lens -This the one to have


from Amherst, MA  -  Photo Enthusiast

This lens is sharp from center to corners. Wide enough for most and just long enough for portraits. Light and well built. Has function button that you can customized. Easy to switch to manual focus and has smooth action . Not macro, but close. Splash proof , I've taken it out in my kayak where it has gotten wet with no problems just wiped with microfiber cloth and kept on shooting. Easy to travel with. The best thing about micro 4/3 is the small light weight lens. This is a pro lens. You can get a less expensive and lighter lens, but, not as fast or as sharp nor as weather resistant in a standard zoom.

Wonder Lens


from Cleveland, OH  -  Photo Enthusiast

This lens is astounding. It's sharp wide open throughout it's range and built like a tank. As good as the legendary Nikkor 24-70mm but at nearly half the cost and a much more manageable size and weight. The killer feature of this lens is also that it's practically a macro lens with such a close focus distance. It won't replace a dedicated macro lens but it might be all any casual macro shooter ever needs.

Excellent Lens


from Gainesville, VA  -  Photo Enthusiast

I am a long time Canon shooter, and my favorite lens is the EF 70-200mm f/2.8L IS II USM. This Olympus lens, while it does not cover the same range is in exactly the same league when it comes to quality photos. I probably could not tell the difference between shots with either glass. The construction is excellent - rock solid, and weather proof. However, the Canon lens attached to my full frame 5D camera is a beast - it is awkward, heavy and highly visible. The Olympus lens is extremely portable, light weight, and takes awesome pictures. I have it on the Olympus OM-D E M10. A perfect marriage of camera and glass. I strongly recommend both.




from Chicago  -  Photo Enthusiast

I'm moving from Nikon APS-C cameras to Micro 4/3s, because of the promising lens lineup and reduced weight. This lens does not disappoint! It produces beautiful blurred backgrounds and is very sharp wide open. It's a worthy successor to my Nikon 24-70 f2.8. As a bonus, it works very nicely with my Nikon 62mm close-up attachments. Videos look great, with nicely blurred backgrounds.

Shopper  Can this lens be used on a 510 without an adapter?
MICHAEL Y  Do you mean E510? If so, then no. So far only Micro Four Thirds body can take Four Thirds lenses with adapter, not the other way around.

Shawn E  Does this have OIS on the lens? Will the lens electronically interact with GH4?
YI KUANG C  No OIS, and yes it should works/interacts with GH4.
