This is an area where "Do it Yourself" measures will only take you so far. A good Physical Therapist will not just address your immediate needs, but give you a plan to continue living with a healthy and strong back. The lessons my PT gave me a decade ago keep me in god shape, when I consistently do them.
Originally posted by lazarustx I sometimes shoot during lunch so I always lug my camera gear with me.
I do the same, but I keep one camera, plus one lens of choice (and my DA 40 XS as a back up), not my entire collection. I rarely wish I'd brought more than one lens and making that lens fit for the situation I find myself in adds to my creativity at times. Plus, selecting a lens beforehand is part of "Pre-visualizing" for future images I hope to create.

Yes. If it works, why not? Otherwise, if there is a suitable wheeled bag that works, consider buying an insert for the lenses and cameras you want to have at hand.
