A suite of aspherical, extra-low dispersion, and high-refractive index elements are featured within the optical design, and help to minimize spherical and chromatic aberrations throughout the zoom range for increased clarity and sharpness. Additionally, a ZERO coating has been applied to control flare and ghosting for improved contrast and color fidelity. A weather-resistant design benefits handling in trying conditions while an L-Fn button offers lens-based control over various settings. Additionally, a Movie & Still Compatible autofocus system achieves fast, smooth, and silent focusing performance to benefit both photo and video applications. As a fast, high-performance wide-angle zoom, this Micro Four Thirds lens pairs an optimized optical layout with refined physical details to excel in a variety of working conditions.

Wide-angle 7-14mm zoom lens offers a 14-28mm equivalent focal length range for Micro Four Thirds digital cameras.

Constant f/2.8 maximum aperture maintains consistent performance throughout the zoom range and benefits working in difficult lighting situations.

The lens construction incorporates two aspherical ED (extra-low dispersion) elements, one DSA (Dual Super Aspherical) element, one aspherical element, three Super ED elements, one ED element, and two HR (high-refractive index) elements into its design to minimize aberrations, distortion, and color fringing while also contributing to overall image sharpness, clarity, and color fidelity.

A ZERO (Zuiko Extra-low Reflection Optical) coating has been applied to individual elements to minimize lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions.

Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance.

Programmable L-Fn (lens function) button for easily accessible settings adjustment.

Dust, splash, and freezeproof construction ensures this lens' performance in inclement conditions and harsh environments.

Built-in petal-type lens hood helps to alleviate stray light from causing flare and also adds some protection from accidental impacts to the front element.

Rounded seven-blade diaphragm produces a smooth bokeh quality.

Related Questions and Answers

Q: 1. Does this lens feature the same clutched focus ring for hard stops and repeatable focus in video and filmmaking as its 12-40 f2.8 brethren?

A: Yes, the focus ring works the same way as the 12-40 f2.8

Q: 2. Does this lens zoom internally? Meaning does the barrel of the lens extend when zoomed?

A: The lens zooms internally with the front element moving within the lens shade. It is a quite bulbous element though so it does require a little care in use. Its a very sharp lens, and Ive been very happy with the purchase.

Q: 3. Will this lens work perfectly with panasonic bodies? For example, the fn botton, pull down focus ring, auto focusing speed and image quality.

A: The Oly lens will certainly mount on the Panasonic camera and meter perfectly. The image quality depends on the sensor size and your ability to control the camera functions for best quality. I don't know if the bells and whistles of the Oly lens will work or not. I hate to let your local camera store be the local showroom for B&H, as many are these days, but possibly the salesman would help you try it on a body. (I wouldn't mention for an instant that you were going to purchase through mail-order in order to get B&H's superior return policy and rock-bottom prices--it always seems to antagonize the salesman).Frankly, my local camera store does not have as good a return/service policy as B&H, in addition to charging full MSRP for items...

Q: 4. Hi. Is this 7-14mm f/2.8 PRO lens compatible with Olympus PT-EP13 underwater housing ?

A: The Olympus PT-EP13 housing as sold is not compatible with the 7-14mm. Though, you might be able to get a third party dome port. I would suggest contacting our Underwater Department directly via email: uw@a href= http://bhphoto.com target= _blank bhphoto.com/a

Q: 5. How is this lens for night orastro photography?

A: Very good lens

Q: 6. What are the chances that Oly has eliminated the infamous wide-open purple fringe aberration found on the Panasonic 7-14mm?

A: Its impossible to know to what extent there may not be purple fringing until the lens is released. That being said, it will have a different optical design with different coatings, so should perform differently than the Panasonic version. Though, purple fringing is always a possibility with super wide zooms. If you shoot stopped down and reframe your shot to avoid high contrast, it can help avoid chromatic aberration.

Q: 7. Does this M.Zuiko 7-14mm PRO lens change length as it zooms like the M.Zuiko 12-40mm PRO or does it maintain the same length and do all it lens movements internally like the M.Zuiko 40-150mm PRO?

A: The lens front glass element changes position (1 ) within the stationary lens hood as it zooms between 7-14mm (most retracted @ 14mm.) The length of the overall lens unit remains fixed (lens hood itself does not extend or retract, and the front glass element doesn't extend beyond the longest edge of the tulip hood.)

Q: 8. I just got this lens- put it on 2 of my m43 Panasonic bodies- but even in AF mode in the camera the lens is only acting as a MF lens..is it faulty or do I need to do something else to get AF working?

A: First check to make sure that the manual focus (push-pull) ring on the lens is in the forward position (away from the camera body). I've been using this lens on a GX8 and a GX85 without any issues, either in auto-focus mode or in manual focus mode. This lens auto-focuses very quickly.

Q: 9. How will this perform for photography on a Panasonic body without IS?

A: I use it on a Panasonic GH4 and Love it.

Q: 10. How does this lens work with a Panasonic GH4? How does it compare to the Panasonic 7-14?

A: This is a standard MFT mount so will work fine with the GH4. the Zuiko 7-14 is a fabulous lens! Super sharp corner to corner, fast f 2.8. I'm loving it. I have not used the Panasonic 7-14 so I suggest you read Gordon Laing's reviews at Camerlabs about these two lenses for in-depth evaluation to help you decide.
