As a 100-400mm equiv. , it provides a lot of reach in a relatively small package, which can be further augmented with a teleconverter, at the cost of light-gathering ability.
As its name suggests, the 50-200mm F2. 8 IS Pro is optically stabilized. The company says it's capable of 7EV of stabilization when paired with a camera that has a stabilized sensor, thanks to its sync IS system. Unsurprisingly given the brand's outdoor focus, the lens is also dust and weather-sealed, and has an IP53 rating.
The lens zooms internally and is made up of 21 elements in 13 groups, including one ED element, two Super ED elements and one ED aspherical lens. It also has the company's "Zero Coating II" for reduced flaring, and a fluorine coating on the front element to repel dirt, oil and moisture.
As an entry in OM System's 'Pro' lineup, it can be used with focus stacking and 50fps continuous AF
The lens has a minimum focusing distance of 0. 78m (30. 7") throughout its zoom range, and can achieve a maximum magnification of 0. 5x at 200mm. It weighs 1075g (37. 9oz) without its tripod collar, and 1250g (44. 1oz) with.
That tripod collar, which has a foot that slots into Arca-Swiss-style mounts, can be removed without any tools, making it easy to unmount the lens from a tripod and use it hand-held. The included hood also has a filter window that allows you to adjust a variable ND or circular polarizing filter without having to take the hood off.
As an entry in OM System's 'Pro' lineup, it can be used with focus stacking and 50fps continuous autofocus on bodies that support those features, such as the OM-1 II and OM-3. It also has a bevy of switches and buttons, letting you control its focus limiter, image stabilization, and the camera's sound settings.
The 50-200mm F2. 8 IS Pro is an interesting addition to OM System's lineup, which has a fair number of telephoto zooms. It offers more reach than the 40-150mm F2. 8 Pro (especially if you're willing to use teleconverters), as well as image stabilization. Those benefits can also be had with the 150-400mm F4. 5 TC1. 25X IS Pro, but that lens is substantially more expensive.
The lens will be available starting October 3, and will cost $3699.

One-of-a-kind high image quality, large-diameter super telephoto zoom lens offering 100-400mm1, F2. 8 equivalent with the lens alone, and up to 800mm1, F5. 6 equivalent when using the 2x teleconverter
This lens features a constant F2. 8 aperture throughout the zoom range, offering a focal distance of 100- 400mm equivalent1. This large-diameter, super telephoto zoom lens delivers 400mm1, F2. 8 equivalent at the telephoto end, and up to 800mm1, F5. 6 equivalent when using the 2x teleconverter. The bright maximum aperture value enables high-speed shutter photography at a lower ISO, making it easy to capture photos of wild birds and wild animals that are active in low light conditions such as early morning and sunset. With its broad focal range, this single lens offers exceptional versatility, even for landscape photography, making it highly capable of capturing a wide variety of scenes.
A lavish, 21 elements in 13 groups lens construction was adopted, including a large-diameter EDA lens and 2 Super ED lenses for a large-diameter F2. 8 with reduced flares and color bleeding across the entire zoom range, and superb resolution to the edges of the image. The new ZERO (Zuiko Extra low Reflection Optical) Coating II effectively suppresses ghosts and flares in backlit conditions for sharp, clear image quality. An inner zoom system is used, which minimizes center of gravity changes while zooming for stable framing and greater comfort during long photography sessions. High-speed, high-precision focusing supports up to 50 fps AF tracking sequential shooting4.
This lens also offers outstanding close-up shooting performance, with a closest focusing distance of 0. 78m across all zoom ranges. Tele-macro shooting is easy with a maximum image magnification of 0. 5x equivalent1 and 1x magnification1 when using the 2x teleconverter. It is perfect for nature macro photography of subjects that tend to be scared off when getting too close, such as insects. Additionally, this lens is compatible with the unique OM SYSTEM feature, focus stacking.
Supports 5-axis sync IS for easy handheld shooting with up to 7. 0 steps2 of shutter speed compensation
This model is compatible with 5-axis sync IS, which works in concert with the camera's in body image stabilization. A high-precision gyro sensor and optimized image stabilization algorithm boast up to 7. 0 steps2 of image stabilization at 400mm equivalent1, the world's highest level5. Image stabilization not only reduces camera shake when shooting, it is also effective for keeping the subject in the frame. It can be very difficult to keep the subject in the frame during handheld super telephoto shooting, but 5-axis sync IS keeps the viewfinder image stable, making shooting much easier.
Despite being a large-diameter super telephoto zoom lens, it is easily portable at approximately 1,075 g (without the tripod mount). This makes for a more compact, lightweight photography system that is highly mobile for greater freedom in chasing down subjects.
Excellent reliability and operation that supports shooting even in harsh natural environments
The IP53 splash & dust proof6 performance and freezeproof design to -10°C provides peace of mind when shooting in challenging environments. The frontmost lens is coated with fluorine, making it easy to wipe off water droplets and dirt so you can quickly resume shooting. Even in natural environments where the weather tends to change suddenly, you can focus on photography without worrying about your equipment getting wet.
The lens barrel is finished with heat-resistant coating. Compared with conventional black coating, this coating efficiently reflects the infrared rays of sunlight, keeping temperatures inside the lens from rising even in blazing hot weather for stable optical performance. The following features are also included so you can focus on shooting.
A rubberized, anti-slip zoom/focusing ring provides fine control
A Focus Limiter switch for quickly focusing according to the distance from the subject
A Focus Mode switch for instantly switching between AF and MF
Preset focus function7 to save and instantly activate your favorite focal position
Four L-Fn buttons7 to which functions can be assigned and naturally operated with fingers while looking through the viewfinder in both vertical and horizontal orientations
The lens hood is equipped with a filter control window and lets you turn a circular polarizing filter, etc. , which is frequently used in landscape photography. A rubber material is used at the tip of the hood to minimize the risk of scratches. The tripod mount can be attached and removed even when the lens is attached to the camera. The tripod mount foot shape is designed for a comfortable grip when carried and is compatible with Arca-Swiss type clamps.
