Take our expertise in lens mount adapters and add something unexpected: a built-in polarizing filter. The Polar Throttle opens new creative possibilities. No more carrying around a camera bag full of filters. Built-in polarizing means easy and convenient image control over any lens that you attach. We offer dozens of choices for both mirrorless and DSLR and film cameras. Compatible Sony E-mount Cameras (including but not limited to): a7/7R/7S, a7/7R/7S II, a7/7R/7S III, a7R IV, a9, a5000, a5100, a6000, a6100, a6300, a6400, a6500, a6600, NEX-3, NEX-5/5N/5R/5T, NEX-6, NEX-7, NEX-C3, NEX-F3, QX1. Please Note: With enough shift movement on certain focal lengths, vignetting may occur. This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc. ) will be disrupted. Set your camera to “Manual' or ‘Aperture Priority' for metering. If camera does not release be sure to enable ‘shoot without lens' in camera settings. We state “infinity focus allowed” because our adapters are designed to be universal which can prevent some lenses from focusing to infinity at the infinity mark.
