The 10-24 is a great lens. If you're on a tripod, I'd be inclined to:
- turn ibis off
- set to f8
- set to iso200
- adjust shutter to get exposure
- remove filters (for now)
- manual focus using the indicator and peaking
I've used this lens extensively and it's sharp. For video, it produces great colours and contrast under artificial light such as stage dance and drama (which is what I spend most of my time filming).
Also, eliminate the obvious such as strap swing, loose tripod, nearby vibrations such as roads/trains etc.
Let us know how you get on.
