Does anyone know if there are generally agreed upon recommendations for the best orientation of lens's during carry/transportation? (both attached to a body and free).
I see the majority of camera bags preferring vertical orientation (which I imagine is best for space) but are lens's better protected from shock forces (bag being dropped to the ground, etc.) in this orientation as opposed to the side-impact forces if the lens in in the horizontal position?
I'm asking as I am failing miserably in my attempt to find the perfect carry bag and have come pretty close (timbuk2 snoop size small insert in a Medium size bag) if I chose to have the camera with attached lens (3ti with 70-300) sitting horizontally (with one of the camera bags pads making a shelf and my flash sitting below the lens also horizontally) but being new to camera's, I worry if this somehow puts the lens in greater risk of being damaged. Further, I previously had to send my 17-85 in for repair after traveling by plane (mysterious error messages) even though I thought I had it pretty well protected in my previous carry-on so now I'm extra paranoid. I could probably have the 3ti/70-300 setup hanging vertically in the same bag although the lens would be resting on the base of the bag (which I would assume would be much more prone to impacts under the weight of the camera body). Other than less efficiently using space, any problems with the horizontal setup (or am I being overly paranoid and the vertical setup would be fine as well)?
Any thoughts or input would be appreciated (especially if I'm just over thinking it).
