Canon EOS: what owners actually say

Multiple owners report high and inconsistent latency when using EOS as a webcam — typically 150–200ms, sometimes approaching 400ms, or even in the half-second range, consistently out of sync with audio.

When used as a webcam via software solutions, resolution is described as low, around 1024×576, far below what the sensor is capable of.

Owners describe spending minutes searching bash history for modprobe commands, recompiling and resigning kernel modules after updates, and dealing with out-of-tree modules that break under Secure Boot.

Most apps required the video device be created before the application process began; trying to read from it otherwise caused issues.

Owner had to place camera beside the screen rather than on top, causing eye-line mismatch during video calls.

Owners report stunning results combining shallow depth of field with quality lenses (e.g. 50mm f/1.2L at f/2.0) and diffused LED video lights, noting the codec benefits from only encoding detail in the narrow focal plane.

Owners note the mini HDMI out provides a live video feed without requiring recording mode, which can be paired with a simple capture card like Elgato for a straightforward webcam alternative.

Owners who used DSLRs with live preview active for extended periods report no issues, noting solid-state construction makes wear negligible.

Owners praise the dual ISO feature, reporting two really clean ISOs for video (discussed as 800/6400 or 800/3200 depending on model), acting like a reset to base ISO in terms of noise.

Owners value high-resolution modes like 7K/8K specifically for open-gate shooting, allowing them to crop horizontally or vertically in post — one owner used 8K on an 85mm to effectively replace a super zoom lens for sports.
