Olympus Announces the M.ZUIKO Digital ED 300mm f/4 IS PRO Lens


Micro Four Thirds users now have a powerful new option for photographing faraway and fast-moving subjects, and we at B&H are pleased to share the news. With the release of the Olympus M.ZUIKO Digital ED 300mm f/4 IS PRO lens, birders, wildlife, and sports photographers can be more certain that they don’t miss the shot while exploring new angles and creative possibilities.

Despite providing a 600mm equivalent focal length, this 300mm f/4 remains compact, measuring just about 9 inches long, as well as being easy to handle at slightly less than 3 pounds. To further ensure that images generated by this lens are sharp, a 5-Axis Sync IS system is built in, and works in conjunction  with the in-camera stabilization systems of the OM-D E-M5 Mark II and OM-D E-M1 to provide up to six stops of image stabilization for sharp handheld image-making in difficult lighting conditions. By combining both lens- and sensor-shift stabilization methods, shake correction is more effective for stills and movie recording while retaining a high degree of image quality.

In regard to the optical design, the lens features three Super ED elements, which suppress chromatic aberrations, as well as three HR elements and one E-HR element to minimize spherical aberrations. A new Z Coating Nano has also been applied to significantly reduce ghosting and flare for increased clarity, contrast, and color fidelity.

While it is clear that photographers who routinely capture images from long distances can appreciate this lens, the needs of macro shooters can also be well served by its 4.6' minimum focus distance and 0.48x equivalent maximum image magnification. When used with the optional M.ZUIKO Digital MC-14 1.4x Teleconverter, the lens’s maximum image magnification is increased to 0.67x, its 35mm equivalent focal length becomes 840mm, and the minimum focusing distance is maintained for close-up shooting capabilities of insects, birds, and other small subjects from a comfortable working distance.

Rounding out the lens’s attributes, its physical construction is accentuated by hermetic seals in 17 places to prevent dust and moisture from entering the lens, making it an ideal companion for working in harsh climates. Handling is complemented by an L-Fn button, which can be programmed to control up to 27 different functions, as well as Focus Limiter and IS On/Off switches, and a manual focus ring. Additionally, the included removable tripod collar features an Arca-type foot for direct compatibility with a variety of tripod heads.

Included with the lens itself, a new LC-77B Front Lens Cap, DR-79 Decoration Ring, and LSC-1127 Lens Case were also announced, as well as an optional 77mm PRO ZERO Protection Filter.

Would be nice if my $Canadian money was not at 70 cents to us $$ dollar
At $2499 great price but
My price using $$Canadian money would be $3694.99 with tax added in
Too much extra cost
Wish I would have kept $us money when the exchange rate was better

This is an exceptional lens, a well-rounded performer if you ask me. Weather-sealing, built like a tank (without the weight of a tank), and optical excellence. I see a trustworthy, independent online test confirms this. I find the price a bit steep though. 

At 2.8 lb, it's not as heavy as my whopping Zuiko 35-100 f/2.0 35-100 mm lens, at 3.64 lb (plus a bit of weight for the 4/3 to micro 4/3 adapter and a bit more for a teleconverter), but heavier than the Zuiko 50-200 mm f/2.8-3.5 ED SWD lens.  I assume the new lens will have much better image stabilization than either of these.  

This will be a monster lens on a M43 system... Tripod not included.

On an OMD EM1 - a tripod or a monopod will not needed in most situations....
