Another geological abstract shot from lower Antelope Canyon in Arizona:

If you’re planning a trip to Antelope Canyon and you’re taking a DSLR, you should give some thought in advance to just what lens(es) you should put on your camera body(ies). Fortunately, you’ve got a strong ally in this effort — namely, Flickr.

Before the trip, scan through Antelope Canyon shots that other people have posted to Flickr to find ones you particularly like. Then, when EXIF data is available for the shots, take note of the focal lengths used for the images — this will give you a very good idea of what you want to be taking along on your trip.

In my case, the images I liked best seemed to be taken with focal lengths around 20-30mm (35mm equiv.). So since I have Olympus four-thirds camera bodies (2x crop factor), I aimed for 10-20mm focal lengths in my lenses. So I had a 7-14mm lens on my E-3 body (primary camera) and 14-54mm lens on my E-520 body (backup). Whichever camera wasn’t being used at the time rested in a padded torso pack (ThinkTank Change Up) to protect it from accidental dings. Meanwhile, both camera bodies were outfitted with quick-release plates for my tripod so I could switch back and forth quickly.

Oh, and both camera bodies have lanyards — so whichever one was in use was tethered to my wrist at all times. Particularly important when there’s nothing soft for a camera to land on if you drop it.
