I'd guess that a photographers vest would have the pockets and loops optimately sized to fit a photographer's equipment and accessories. I would think that if a vest is being marketed as a survival, tactical, or safari vest it might be optimized differently. I don't know, I have load bearing vests that I have to wear as part of my uniform, but I prefer an old school H harness when I can get away with it.
I like blade and notch sights on a shotgun, it's helpful when I'm making well aimed shots and doesn't get in thw way for rapid shots. I have no use for scopes or other gadgets on a scattergun though.
I think previous posters nailed it on the head when they described how overused the term "tactical" is, but it is a fitting way to describe the difference between the way you'd reload or shoot at the range versus the way you'd do it in a life threatening situation.
