Smart Alec interior dimensions for a camera insert?
Calling all Smart Alec owners... would someone be kind enough to tell me the interior footprint for the SA? Is it round, square, etc.? How wide across the interior bottom of the bag? I want to get an insert to bring my SLR and extra lens with me, but my SA will not be here till July. I have an old Nikon D80, a 50mm/f1.4 lens, and a 28-105 zoom (which is a smidge over 4 inches tall and 3"/diameter). In the past I carried these in a separate Lowepro pack, but want to streamline for this trip as we will be moving every 3-4 days. Do I recall correctly that the SA has some padding on the bottom, too?
Alternately, if you already use an insert and have a name/link to recommend, I'm open to suggestions! How much space do you have left at the top of the SA, if you put the insert at the bottom? My plan is to have the camera at the bottom of the pack when I'm using the SA as a carryon, so I just want a little bit of protection. When we're out sightseeing, I'll just carry the camera around my neck or over my shoulder (i.e. not worried about needing to pull the camera out quickly).
Thanks so much!
