2 questions:
1) Is there a way to override the dials (this answer can probably be found somewhere, but I thought I might as well ask it here)?
2) Have you guys had a chance to test the new 10-24mm?
the override is an interesting question, as I was also thinking about that, such that the camera can take advantage of the front and rear dials to control a combination of Aperture, Shutter Speed, and EV (and even ISO). This is what we have come accustomed to with the DSLRs and digital cameras. But note that these are usually cameras that don't have the dedicated aperture, shutter speed, EV or ISO dials.
at the 11th hour, before return the camera, I was running through the camera menu, but didn't find such an override to the Aperture, Shutter Speed, EV or ISO dials. but going back to the design of the X-T1 (not that I was involved in the design of it), retro-styling on the X-T1 is very much a modern impression of the dials found on the old SLRs. Having these physical dials make these features available and accessible with dedicated dials for each of these shooting parameters / variables. For the non-R lenses (lenses without aperture rings), the dials would be used to control the aperture.
Aperture Ring set to "A" gives Shutter Priority mode
Shutter Speed set to "A" gives Aperture Priority mode
Both Aperture and Shutter Speed set to "A" gives Programme mode
But from the quick look, i didn't see the override option. But if it does, it would be great as you could get the best of both worlds. The hands-on session is this Saturday (tomorrow), and I'd be a little more deliborate in checking on this, and will update if I do find the override.
As for the 10-24, haven't played with it. But if you're keen, I'm sure that they would have it available at the hand-on session tomorrow.
