The Fotodiox 2x Teleconverter for Canon cameras is a precision optical component designed to expand your photographic capabilities. This premium quality 2x teleconverter, effectively doubles the focal length of the lens it's used with and maintains the resolution and contrast of any fine optic. The teleconverter will multiply the focal length of the existing lens by 2x and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300 mm lens will effectively increase the focal length to 600 mm and a lens set to f/2.8 will now be f/5.6. A maximum aperture of f/4 or greater is required in order to fully utilize the autofocus capabilities. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with a smaller open f-stop value than those given above. A teleconverter is a portable, high-quality and versatile accessory that's well worth having in your camera bag!

The Sigma 10-20mm F3.5 Ex DC HSM is a super-wide angle lens that has a maximum aperture of F3.5 throughout the entire zoom range. With its wide angle view from 102.4 degrees it can produce striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 9.4 inches (24cm) throughout the entire zoom range and a maximum magnification ratio of 1:6.6. The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood and polarizing filter. The Petal-type hood blocks extraneous light and reduces internal reflection.

Are you seeking a way to add autofocus to your Leica M lenses? Look no further than the Fotodiox Pro PRONTO Autofocus Adapter Mark II. This innovative device transforms manual lenses into autofocus powerhouses, compatible with Sony E-mount cameras. Simply attach your M-mount lens to the PRONTO adapter and experience the convenience of automatic focusing.The PRONTO adapter is designed for optimal performance with 50mm and wider lenses. For general use, it's suggested to set the lens to infinity focus, enabling autofocus within the entire focusing range. By half-pressing the shutter button, the PRONTO adapter activates the autofocus, making your lens function like any other AF lens. For telephoto optics, a coarse manual focus is required before fine-tuning with the adapter's autofocus feature.Enhance your close focus ability with the Fotodiox Pro PRONTO adapter. By attaching your lens and setting it to the closest focus distance, the PRONTO adapter doubles as a 5mm extension tube. This setup significantly shortens the minimum focus distance of your lens, with the effect being stronger the wider the lens.The PRONTO adapter features a Leica M-mount, but its versatility doesn't end there. With additional adapters, you can adapt nearly any lens to Leica M, attach it to the PRONTO adapter, and enable autofocus. However, not all adapters will be compatible due to size limitations imposed by the motor housing of the PRONTO adapter.The function button on the side of the Pronto allows the user to enter various focus modes, as well as setting the focal length and maximum aperture of the lens used on the adapter for optimum compatibility. It's compatible with the Phase Detection autofocus (PDAF) system on the a7 II, a7R II, a9II, a6500, and a6600. This adapter supports both AF-S and AF-C focusing modes, face detection, and up to 5-axis stabilization on supported cameras. Please note that decreasing the focus area may result in a significant reduction in speed and potential focus hunting. The Pronto adapter is not recommended for cameras with only Contrast Detection Autofocus (CDAF) like Sony NEX, a6000, a7, a7R, a7S, a7Sii, etc., as it doesn't function properly with CDAF. Cameras in hybrid autofocus mode, such as Sony NEX, a6000 series, a7 & a9 series, may deliver unsatisfactory performance due to their reliance on CDAF. In conclusion, the Fotodiox Pro PRONTO Autofocus Adapter Mark II is a versatile tool that brings autofocus to your Leica M-mount lenses, enhancing your photography experience with Sony E-mount cameras.
