Svbony SV195 T Ring Adapter EF Mount for Canon EOS DSLR Telescope
The Svbony SV195 T Ring Adapter provides a secure, adjustable connection between your Canon EF-mount DSLR and any M48x0.75 threaded accessory. Three screws on the side release the inner ring, so you can rotate the camera to level or frame your shot and then lock it again.
M48x0.75 Threads: A Direct Connection to Your Imaging Train
The SV195 features standard female M48x0.75 threads, making it the ideal interface for connecting your Canon EOS camera to modern field flatteners, reducers, or coma correctors. This larger thread size minimizes vignetting compared to older T2 (M42) standards, especially when using cameras with full-frame or APS-C sensors.
3-Screw Adjustment: Rotate and Level Your Camera
The SV195 has an integrated horizontal adjustment ring. Loosen the three small screws on the adapter's side, attach the camera, turn it to the orientation you want, then retighten the screws. This lets you level the camera or square your framing on a target without loosening the rest of your imaging train.
SV195 vs. Standard T-Rings: The Advantage of Adjustability
A standard T-ring locks the camera at whatever angle the threads happen to stop. The SV195's adjustable inner ring lets you set the camera's rotation after it is mounted, so your frame is level or aligned with the target. It does not correct sensor tilt; that needs a dedicated tilt adapter.
What is the main benefit of the Svbony SV195 T-Ring over a non-adjustable one?
The main benefit of the Svbony SV195 is its 3-screw adjustment system. Loosening its three side screws lets you rotate the camera to level or frame your shot and then lock it again, which a fixed T-ring cannot do.
Which cameras are compatible with the Svbony SV195 adapter?
The Svbony SV195 is designed for any Canon DSLR camera that uses the Canon EF or EF-S lens mount. This includes the vast majority of Canon EOS cameras. It is not compatible with Canon's newer RF or M mount systems without an additional EF-mount adapter from Canon.
What does the M48x0.75 thread on the Svbony SV195 connect to?
The M48x0.75 female thread is a common standard in astrophotography, often called a "2-inch filter thread" or "wide T-ring thread." It connects directly to most modern field flatteners, coma correctors, and off-axis guiders that are designed to illuminate larger sensors and minimize vignetting.
Is the adjustment process for the Svbony SV195 difficult?
No. Loosen the three side screws, turn the camera to the angle you want, and retighten them.
