Precision Fit - Low Profile
2" UltraWide Prime Focus Adapter for Canon RF Mount Mirrorless Cameras For All Canon EOS R Models As seen in Sky & Telescope Magazine. The "UltraWide" Clear Aperture is Over 10mm Larger than a T-Ring adapter! ZERO VIGNETTING OF THE CAMERA SENSOR. Low Profile 2" UltraWide Adapter for Canon EOS-R Mirrorless Models The 2" Barrel inserts directly into 2" Eyepiece Ports. Provides a 10mm Larger Clear Aperture than a T-Ring Setup! Installed Length Only 10mm. Overall Length 34mm. Threaded for standard 48mm (0.75) 2" Eyepiece Filters. LOW PROFILE: Allows True Prime Focus in most Reflectors! Precision Fit - No Slop Bayonet Mount! FREE GLASS DUST FILTER INCLUDED - LIMITED TIME OFFER. This Custom Adapter Solves 2 Big Problems 1. Standard T-Ring setups will cause significant vignetting (corners of the image clipped off) when used with Cameras with Large Full Frame Sensors such as the EOS R Series. This 2" UltraWide adapter bypasses the restrictive T-Ring connection, providing the widest possible clear aperture available in a 2" adapter. There will be no adapter induced vignetting with this adapter. 2. Standard T-Rings for Mirrorless Cameras such as the EOS R Series are very deep (actually tubes) to meet the T2 back-focus standard carried over from telephoto lenses. This results in over an inch of wasted back focus. This Low Profile adapter has an installed length of only 10mm. That is Big News to Reflector owners.. as they can now likely reach True Prime Focus for the first time.. without the need for Ba rlow Lenses or telescope modifications. For everyone else it means you have an extra inch of back focus for accessories like filter wheels! We also stock Wide 48mm T-Rings and Short T-Minus Rings for Mirrorless Cameras.
