Features:

2x Teleconverter for Instant Focal Length Extension

The OM SYSTEM MC-20 instantly doubles the focal length of compatible M.Zuiko lenses, giving photographers significantly more reach without changing to a larger super-telephoto lens. This allows you to capture distant wildlife, birds, aircraft, athletes, and other faraway subjects with greater detail while maintaining the portability of your existing camera kit. Instead of investing in multiple long telephoto lenses, the MC-20 provides a practical and cost-effective way to extend your shooting capabilities with a simple attachment.

Professional Optical Design with 9 Elements in 4 Groups

Engineered specifically for professional photography, the MC-20 features a sophisticated optical construction consisting of 9 precision-engineered elements arranged in 4 groups. This advanced design helps maintain the outstanding image quality of compatible M.Zuiko lenses by preserving sharpness, contrast, and color fidelity even after the focal length is doubled. The carefully designed optics minimize image degradation commonly associated with teleconverters, allowing photographers to achieve excellent results in demanding shooting situations.

High Refractive (HR) Lens Element for Superior Image Quality

A dedicated High Refractive (HR) lens element is incorporated into the optical design to improve image performance across the frame. This specialized optical element helps reduce various optical aberrations while maintaining excellent resolution and clarity from center to edge. The result is cleaner, sharper images with improved overall optical performance, making the teleconverter suitable for high-resolution camera systems.

ZERO Coating Reduces Flare and Ghosting

The MC-20 utilizes OM SYSTEM's renowned ZERO (Zuiko Extra-low Reflection Optical) Coating to suppress internal reflections that can reduce image quality. By minimizing flare and ghosting, this advanced coating helps produce images with richer contrast, deeper blacks, and more accurate colors, even when shooting in challenging lighting conditions such as direct sunlight, backlit scenes, or bright reflections. This allows photographers to maintain excellent image quality across a wide range of outdoor environments.

Maintains Full Electronic Communication Between Camera and Lens

Unlike basic optical accessories, the MC-20 preserves complete electronic communication between compatible cameras and lenses. Autofocus, electronic aperture control, EXIF data recording, image stabilization, and other supported camera functions continue to operate seamlessly. This ensures photographers can continue using advanced shooting features without sacrificing convenience or functionality, making the teleconverter feel like a natural extension of the lens.

Compatible with Autofocus and Image Stabilization

The MC-20 is designed to maintain autofocus performance and image stabilization when paired with officially compatible M.Zuiko lenses. Photographers can continue tracking moving subjects while benefiting from stabilized shooting, making handheld photography more practical even at significantly longer effective focal lengths. This combination is especially valuable for wildlife, birding, sports, and aviation photography where speed and stability are essential.

Professional Weather-Sealed Construction for Outdoor Photography

Built for photographers who regularly work in unpredictable conditions, the MC-20 features a professional-grade weather-sealed design that is dustproof, splashproof, and freezeproof down to -10°C (14°F) when used with compatible weather-sealed OM SYSTEM equipment. Whether photographing wildlife in rain, hiking through dusty trails, or working in cold mountain environments, the teleconverter is designed to withstand challenging conditions without compromising reliability.

Compact and Lightweight Design for Maximum Portability

Despite offering a substantial increase in focal length, the MC-20 remains remarkably compact and lightweight. Measuring just 25.9 mm in length and weighing approximately 150 grams, it easily fits into almost any camera bag or pocket. This portability makes it an excellent travel companion for photographers who want to extend their shooting range without carrying additional heavy telephoto lenses.

Durable Metal Mount for Reliable Performance

The teleconverter is equipped with precision-machined metal mounts that provide a secure connection between the camera and compatible lens. This robust construction ensures long-term durability, stable alignment, and dependable performance during frequent lens changes, making it suitable for both professional assignments and intensive outdoor use.

Expands Telephoto Photography Without Replacing Your Existing Lens

Rather than purchasing another expensive long telephoto lens, photographers can simply attach the MC-20 to compatible M.Zuiko lenses and instantly achieve twice the focal length. This provides exceptional flexibility while maximizing the value of existing equipment, making it an economical upgrade for photographers who regularly need additional reach.

Excellent for Wildlife and Bird Photography

The additional magnification provided by the MC-20 makes it ideal for photographing subjects that are difficult or impossible to approach. Birds perched high in trees, distant wildlife across open fields, and elusive animals can all be framed more tightly without disturbing them. This increased reach allows photographers to capture greater detail while maintaining a safe and respectful distance from wildlife.

Ideal for Sports and Aviation Photography

Fast-moving subjects often require long focal lengths to fill the frame. The MC-20 enables photographers to bring athletes, race cars, aircraft, and other distant action closer while maintaining autofocus compatibility and image stabilization. This helps produce more dynamic and detailed action photographs without requiring specialized super-telephoto equipment.

Enhances Macro Photography with Greater Working Distance

In addition to extending telephoto reach, the MC-20 also increases the effective magnification of compatible macro lenses. This allows photographers to capture larger close-up images while maintaining a greater working distance from insects, flowers, reptiles, and other delicate subjects. The additional space makes lighting easier to control and reduces the likelihood of disturbing living subjects during macro photography.

Preserves Professional Image Quality Across Compatible Lenses

The MC-20 has been specifically engineered to complement the optical performance of compatible M.Zuiko lenses. Its precision optical design helps maintain excellent sharpness, contrast, and color reproduction while minimizing common optical issues such as chromatic aberration, flare, and ghosting. This ensures photographers continue to achieve professional-quality results even when extending focal length.

Designed for Compatible M.Zuiko PRO and Telephoto Lenses

The teleconverter is optimized for selected M.Zuiko PRO and telephoto lenses, ensuring reliable mechanical compatibility, optical performance, and electronic communication. By tailoring the design specifically to compatible lenses, OM SYSTEM delivers a highly integrated accessory that works seamlessly within the Micro Four Thirds ecosystem.

Cost-Effective Alternative to Purchasing Another Super-Telephoto Lens

Investing in a super-telephoto lens can be expensive and significantly increase the size and weight of a photography kit. The MC-20 offers an affordable alternative by allowing photographers to expand the capabilities of lenses they already own. This makes it an excellent choice for enthusiasts and professionals looking to maximize versatility while minimizing equipment costs.

Built for the OM SYSTEM and Olympus Micro Four Thirds Ecosystem

The MC-20 integrates seamlessly into the OM SYSTEM and Olympus Micro Four Thirds system, making it an ideal accessory for photographers who already use compatible cameras and lenses. It preserves the compact philosophy of the system while dramatically increasing photographic reach, allowing users to enjoy greater creative flexibility without compromising portability, durability, or professional performance.
