FAQs:
Can I use normal screw-in filters with the RF 10-20mm?
No front filter thread – it uses rear gelatin filters only. We provide clear protection gel if needed.
Is this lens too wide for everyday tourist photography?
10 mm is extreme, but 15–20 mm is very usable for landscapes and group shots – most travelers keep it on the camera all day in Kyoto and Tokyo.
Does it work on older bodies like EOS R or RP?
Yes, but a free firmware update is required for full compatibility and peripheral control features.
Is the image stabilization good for handheld video?
Excellent – 5-stop optical IS + coordinated IBIS gives buttery-smooth walking footage even at 10 mm.
Is the lens weather-sealed for rainy days in Japan?
Fully L-series sealed – it handles rain, temple mist, and sea spray without issue.
