I've gone and tagged the Brand on twitter, but good lord. The T3i is only what, ten years old, my paper manual was printed in 2011
and I cannot find the dioptric adjustment lenses for sale anywhere online. B&H and Adorama are out of stock, Canon's website doesn't list any dioptric lenses at all, like you click on the product category and it's blank, and like. I would like to be confident in shooting with my nice camera.
I have the diopter wheel cranked as far clockwise as it'll go, and it seems to be passable there, but I'd like the margin of maybe a -1 adjustment or something to it.
Where do you find one of these without spending more than the camera's worth on it? And I got this camera for free, it was a hand-me-down, so like. If something costs fifty bucks and it's not "a lens" or "a handful of batteries"
Does anyone know where I can find one of these in 2022?
The manual lists them as "Canon Dioptric Adjustment Lens E" (10 types, sold separately).
