About the Olympus M. Zuiko ED 300mm f/4 IS PRO

Olympus M. Zuiko ED 300mm f/4 IS PRO

The Olympus M. Zuiko ED 300mm f/4 IS PRO is weather-sealed for shooting in harsh conditions.

Extend your reach

With a 35mm equivalent focal length of 600mm, the Olympus M. Zuiko ED 300mm f/4 IS PRO has amazing reach for its size. Seriously, a pro-quality lens that covers that much ground and weighs in at less than five pounds (3.25, to be exact) is pretty much unheard of. Add Olympus' MC-14 1.4X teleconverter to extend this powerful lens' focal length to a whopping 840mm. The best part? Thanks to its light weight and built-in image stabilization, you can use it without a tripod. This premium lens boasts professional build quality with durable metal construction and protective weather-sealing for smooth, long-lasting performance in all kinds of harsh conditions. According to Olympus, innovative construction and new coating technology make this the highest-resolution lens the company has to offer.

Fantastic Lens for Wildlife and Sports Photography

Arthur from Groton, MA on 3/4/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a fantastic lens for wildlife when used on my Olympus OM-D E-M1 Mark II camera.This lens is the equivalent of an f/4.0 600mm lens on a full frame DSLR like my Canon EOS 5D Mark II. Combined with a the Olympus MC-14 1.4X teleconverter you have the equivalence of an 840mm lens. In addition I have a lot more image stabilization with the Olympus camera/lens combination. Couple this camera/lens combination with the Olympus EE-1 Dot Sight viewer mounted to the hot shoe of the camera, and you can easily track birds or other fast moving wildlife. Because I now have this lens, I am going to sell my almost new Canon 100 - 400mm f/4.5-5.6L IS II USM lens. I compared images taken with both rigs and found major advantages with the Olympus camera/lens/viewer with no discernible loss of image quality.

Pros: light weight, easy to handhold, great image stabilization, fantastic images

Cons: None!

Fantastic lens. Still learning how to use it.

Bob from Pacific Grove, CA on 4/12/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was amazed when the first production run of this lens sold out before the lens was released. The second production run also quickly sold out. Even now, a year after the official release, this lens is still in short supply. It took me some time to save up enough money to buy this lens. It was worth waiting for. I'm using this lens for birds, and discovered to get the most of out of this lens, I needed to completely change my settings. For what it's worth, here is what I'm currently using MySet 1, for birds on the ground  S-AF + MF  Shutter priority - start @ 1/1250.  Auto ISO from 200 to 1250  Single, small focus point.  Low speed burst. I'm using Low-speed burst anti-shock.  IBIS on Auto MySet 2 for BIF:  C-AF  9 box focus  Low speed burst.  SRL Lounge recommends 1/800" to 1/2000" for flying birds. I know that with anything slower, wings blur.  Other settings as per MySet 1

Pros: Minimum focus distance is 4.6'. At that range, this lens doubles as a macro. The tripod mount works well with the HLD-7 battery grip to balance the camera and lens when it is not mounted on a tripod.

Cons: It's expensive. At some point, Olympus may lower the price, but a year after its release, demand is still strong, so I wouldn't count on a price reduction anytime soon. Add the MC-14 tele-converter and HLD-7 battery grip, and you are carrying 5 1/2 pounds of gear. This is much lighter than the DSLR or Full-frame equivalent, but it is still a lot of weight.

The Zuiko 300mm f/4! mounted on the EM-1 it gives incredible stabilization, stunning pin sharp images even wide open. I must mention Crutchfield that They are an excellent company to buy from. We found them very courteous, professional and informative and would rate their company at the tops.

Razor sharp lens!

David from Silver Spring, MD on 10/1/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

The sharpest lens I've ever used! I was amazed at the detail at 100% magnification. I photographed the head of a buffalo with flies on it at about 30 ft away, and when I enlarged the image, you can see the structure on the flies wings. It's relatively small (compared to a full-frame 600mm lens) and easy to carry. The maximum magnification is almost 0.50X, so you can get incredible close-up shots.

Pros: Ultra sharp, compact, close-up capability, quick and precise focusing.

Cons: none

Great service great lens

Crutchfield customer from Annandale, VA on 9/2/2016

Crutchfield customer service was outstanding and I was able to try the lens on the weekend I received it. It is a well build lens, heavy but compared to the equivalent full frame lenses small lens well balanced on the Olympus EM-1. The auto focus 3 range distances speed up the focusing and I was able to catch some pictures of hummingbirds. color and sharpness are excellent. This will be my preferred lens for wildlife photography. All pictures were taken without a tripod possible because of the great OIS.

Pros: Handheld great pictures,

Cons: None found yet

outstanding long telephoto

Crutchfield customer from Seattle, WA on 4/6/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

Optical lens performance is superlative. Very even sharpness wide open (f/4), and no visible vignetting. Used with optional 1.4x teleconverter, performance is still very good (albeit at f/5.6, which is getting a bit dark for shooting wildlife at dusk). Handling is great as well, the highlight would be effective stabilizer that allows for critical sharpness down to 1/15" on my OM-D E-M1. For comparison: With the Olympus 75-300mm f/4.8-6.7 II, I never managed a sharp picture at faster than 1/100" (with IBIS on the E-M1), so this is a very meaningful improvement. Neither here nor there: Focus could be faster (compared to Nikon D4 with 400mm lens). Focus limiter helps (and this lens does have one), but not the best you can buy for randomly moving subjects (I find birds to be sometimes easier compared to e.g. rabbits). To at least help with target acquisition I purchased the Olympus laser sight EE-1 to go with the 300mm and initial results are promising. I simply don't have enough experience shooting at 600mm equivalent field of view to be able to acquire the target rapidly otherwise. Size and weight: I wish it were smaller. It fits tightly in some of my DSLR bags like those used for e.g. a 200mm f/2.8 full frame lens, but moving to m43 I had hoped to be able to pack smaller. Weight is not an issue at all, but would recommend to use the HL-7 battery grip if shooting with E-M1 (or equivalent for other cameras). I don't think that the size of the body matters at all (used w

Pros: Optical performance Handling Build quality

Cons: seriously no cons - if you want 300mm on m43, this is the definitive reference

More details on the Olympus M. Zuiko ED 300mm f/4 IS PRO

Mark G.

Product Research


Micro Four Thirds Mount: The Olympus M.Zuiko Digital ED 300mm f4.0 IS PRO lens has a Micro Four Thirds mount, and is compatible with the Olympus PEN and OM-D interchangeable lens cameras.

Lens Construction: The 300mm f4.0 IS PRO lens delivers superior optical performance due to the multiple lens elements that make up its construction. There are 17 lens elements in 10 groups. The lens includes 3 Super ED, 1 E-HR, and 3 HR lens elements to reduce color bleeding and chromatic aberrations that typically occur in super-telephoto lenses. The lens also features Z Coating Nano lens coatings to eliminate lens flares and ghosting caused by in-frame light sources.

Weather-resistant: The M.Zuiko 300mm PRO lens features premium metal construction that is hermetically sealed in 17 locations to protect the inner workings from moisture and dust. The lens is not only splashproof and dustproof, but is freezeproof down to 14°F (-10°C) to complement the weatherproof camera body of the Olympus OM-D line.

Image Stabilization (IS): The lens features internal image stabilization that works hand-in-hand with the 5-Axis Image Stabilization found in select OM-D cameras to give you compensation of up to 6 shutter speed steps. With this Synchronized Image Stabilization, you get crisp, clear telephoto images, even without a tripod. You can turn the image stabilization on or off via the IS switch on the lens barrel.

Auto Focus: The M.Zuiko Digital lens is equipped with a single internal focusing element that gives you blazing fast autofocus performance. The lens has silent autofocus and aperture mechanisms to make the lens Movie and Still Compatible (MSC). Most OM-D cameras have a Silent Mode with an electronic shutter that let you focus and shoot in complete silence.

Focus Limit Switch: The 3-way Focus Limit Switch lets you limit the focusing range of the lens. If you know ahead of time that your focus range will be short or distant, you can significantly cut the focusing time by selecting the range. You can choose from the following ranges: Full Range (1.4 meters to infinity), 1.4 (55.1") to 4m (13.1'), or 4m to infinity.

Manual Focus Clutch: The 300mm f4.0 IS PRO lens features a manual focus clutch on the focus ring to let you instantly shift from autofocus to manual focus. The clutch allows you to manually preset a focus position using the distance meter. When you pull the clutch ring toward you from the AF mode, the lens returns to the preset focus position.

Integrated Lens Hood: The lens includes an integrated lens hood which can be pulled forward to help prevent stray light from entering the lens. When in use, the lens hood also protects the front lens element from scratches and damage. The lens hood adds nearly 2" to the overall length of the lens when extended. The hood cannot be removed from the lens.

Lens Function Button: The L-Fn (Lens Function) button on the barrel of the lens can be programmed to perform one of 27 different functions.

Tripod Mount: Because of the length and weight of the lens, the M.Zuiko 300mm PRO lens comes with a tripod mount. The tripod mount gives you better balance when shooting from a tripod. You can also quickly rotate the camera from portrait to landscape orientation, or vice versa, with the tripod mount. Marks at 0°, 90°, 180°, and 270° let you perfectly align the camera. The tripod mount's base is compatible with many quick release shoes found on professional tripods. When not in use, the tripod mount can be removed and replaced with the included decoration ring.
