- Key Specs
- Lens Mount Compatibility: Micro Four Thirds
- Lens Type: Telephoto Zoom
- Minimum Focal Length: 25 millimeters (The minimum distance between the lens and the image sensor that allows the subject to be in focus. The shorter the focal length, the greater the area of scene captured.)
- Maximum Focal Length: 50 millimeters (The maximum distance between the lens and the image sensor that allows the subject to be in focus. The greater the focal length, the smaller the area of scene captured.)
- Maximum Aperture: f/1.7 (The limit to how wide a lens can be open, typically expressed in f-numbers. The smaller the number, the larger the aperture and the more light that can enter the lens. A larger aperture creates a shallower depth of field, helpful for keeping subjects in focus and blurring background details.)

LEICA DG VARIO-SUMMILUX 20-50mm / F1.7 ASPH. H-X2550 lens is built for mirrorless Micro Four Thirds (MFT) mount cameras, enabling F1.7 aperture brightness throughout the entire 50-100mm (35mm camera equivalent) zoom range. Its exceptionally high optical performance is suitable for both professional photographers and videographers. Comprising 17 elements in 12 groups, the lens system features three aspherical lenses and four ED (Extra-low Dispersion) lenses that effectively suppress the axial chromatic aberration and chromatic aberration of magnification. Spherical aberration and distortion are also corrected by the aspherical lenses for stunningly high resolution. The use of aspherical lenses and the optimum design of the lens system results in a compact size and light weight. Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision auto focusing. In addition to the silent operation achieved by the inner focus drive system, the stepless aperture ring and micro-step drive system in the aperture control section help the camera to smoothly catch up to brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming. A focus ring is equipped for intuitive, precise focusing and linear/ non-linear setting can also be switched with this ring.
- Leica Lens Performance for All LUMIX Micro Four Thirds Cameras: Strict LEICA quality standards now in a F1.7 Micro Four Thirds (MFT) camera lens for professional photographers and videographers
- Exceptional Optical Performance Across the Full Zoom Range: Bright F1.7 aperture is available across the entire zoom range of 25-50mm
- Stepless Aperture for Smooth, Even Brightness: A stepless aperture ring and micro-step drive aperture system ensure optimal, consistent light when zooming or panning
- Minimize Image Shifts During Zooming: The optical design achieves exceptional barycentric stability to minimize image shifts during zooming
- Rugged Design: Dust/splash*/freeze-resistant design withstands heavy field use under harsh conditions (*Dust and splash resistant does not guarantee that damage will not occur if this lens is subjected to direct contact with dust and water.)

Capture professional pictures and videos with this Sony FE 50mm f/1.8 camera lens. The spherical optic design and double-gauss configuration provide crisp and clear images by minimizing aberrations, while the lightweight profile ensures seamless operation and portability. This Sony FE 50mm f/1.8 camera lens is compatible with the E-mount camera body and full camera format for versatile use.

Perfect for wildlife, sports, travel and more, the RF100-400mm F5.6-8 IS USM is a compact, lightweight telephoto lens for EOS R Series cameras, offering a versatile zoom range that brings subjects closer with ease. The RF100-400mm F5.6-8 IS USM is similar in size to the EF 70-300mm F4.5-5.6 IS II USM lens, and not only reaches to 400mm, but also has fast Nano USM focusing and up to 6 stops of Coordinated IS when used in combination with an EOS R series camera featuring In-body Image Stabilization, like the EOS R5 and EOS R6, or 5.5 stops with an EOS R/RP camera. Using a single Ultra Low Dispersion lens element towards the front of the lens group corrects chromatic aberration throughout the entire zoom range, making your images look crisp and colorful with minimal color blur. The RF100-400mm F5.6-8 IS USM lens can also accept both the RF1.4x and RF2x tele extenders giving you the effective maximum focal length of 560mm and 800mm respectively. With a control ring that allows for quick setting changes, including shutter speed and aperture, the RF100-400mm F5.6-8 IS USM lens puts quality, convenience and control in your hands.

Some items like your keys or wallet you just take everywhere you go because you just never know. For anyone with an EOS R series camera, add the RF50mm F1.8 STM lens to that list. As part of the EOS R System, it’s nice and compact thanks to its RF mount so you can shoot – and get a great shot – anywhere and anytime. Size isn’t all though. As a fixed focal length lens, it lets you be creative with composition and can be used for a wide range of scenes from snapshots to portraits, landscapes to low-light situations and more. Those images will stand out, too, just like you intend whether on social media, or when sharing or printing, thanks to impressive optical features like a PMo aspherical lens to suppress aberrations, Super Spectra coating to reduce flaring and ghosting, and a large f/1.8 aperture for low-light shooting and beautiful bokeh. Pick it up and use it one time and you’ll see for yourself, and you won’t be able to leave the house without it.
