I have the EF-S 10-22mm f/3.5-4.5 USM.
Now the aperture of the lens does not work.
I am going to be taking a short film and
I will use the "Prores Film mode
Should I buy Sigma 8-16 or Sigma 10-20?

Additional questions
I have to sell the EF-S 10-22mm f/3.5-4.5 USM is better?
Or waiting for a firmware update should I do?

Do you need to use the lens immediately and want a replacement lens?
Buy a new lens. Don't sit around waiting for an indefinite firmware update.

Do you need it for just this one shoot?
Rent a lens.

Do you have access to a DSLR?
You could always change the aperture on there and then swap the lens over (a pain, but it works for now).

The 8-16 is rectilinear and wider. The 10-20 is not.
Do you like distortion and don't need the extra 2mm?
Get the 10-20.

Do you not want distortion and want a wider lens?
Get the 8-16.


This did not need its own thread. There's tons of other lens discussion threads.

A question the tokina 11-16 or Sigma 8-16 ?
I want the best sharpness and color rendition.
for Bmcc EF. mount.

Both lenses are rectilinear ultra-wide zooms which can produce very good-looking results, but there are differences.

The Sigma 8-16mm is significantly wider (percentage-wise) than the Tokina 11-16mm. The Tokina is significantly faster and is constant-aperture, and has front filter threads. The Sigma's protruding front glass can make it difficult/impractical to use lens-mounted filters, and the Sigma is so extremely wide it requires a very wide matte box to be used in that combination.

If you decide to use the Tokina, be mindful of the FFD (infinity focus) issue some (especially early) BMCC cameras can have with it (BMD has a fix). See:
