Long story short, I'm getting an opportunity to go on a once in a lifetime trip for a car (particulary Nissan Z) enthusiast. Someone I know who is well connected is taking a small group of us to Japan in a few months to go inside the Nissan factory, into the their "secret" warehouse at Zama (see pic below), hang with the execs of Nissan/Nismo, sit in the pits at a GT race, and a long list of other crazy things that aren't available to the general public.
I want to pick up an UWA lens for this trip b/c I'll be shooting cars at close range. I'm shooting with a Canon 40D. I'm taking my 24-105L as my walk-around lens for general purposes, but would switch to the UWA for particular events.
I was set on getting a Canon 10-22, but after doing some reading the Tokina 11-16 is also a possibility b/c it's a 2.8. I'm not worried about shooting outdoors (would go with the 10-22), but see the picture below of this massive storage facility. I know on more than one occasion, I'll be shooting in an indoor place with this kind of lighting and I probably will not have my tripod. So I need to be sure I can capture handheld pics like this one my friend took a few years ago.
Considering the indoor location/lighting like this along with shooting outdoors, would you guys recommend the Canon 10-22 or the Tokina 11-16? Thanks in advance.
