Do Pentax 10-17mm, Sigma 10-20, and Tamron 10-24 have a physical aperture control?

I need to record some video on a K-5 so my only way of having control over the aperture is if there is a physical, manual control on the lens itself. I have the Tamron 28-75 and it does have an aperture ring you can rotate on the lens, does the Tamron 10-24 have the same? Do the Sigma 10-20 and the Pentax 10-17?

None of those lenses have aperture rings, unfortunately. This isn't something you'll find on many modern lenses.

The K-3, K-50, K-500, and K-30 all allow you to set the aperture manually through the body, however

The widest rectilinear lens I got with a ring is my Sigma 20/1.8. Maybe look for something like Samyang if primes works for you?

Unfortunately primes would get too expensive since I'll need at least 2/3. I might as well just buy the sigma 10-20 + a k-01 and just get manual video controls like that. Which may actually be what I end up doing. Thanks for the help!
