Look at how much stuff you have to carry in your "kit"
Plus it also depends on what you shoot and what you plan on shooting later.
I can't afford to be missing shots or having slow shutter speeds at a wedding or event. Especially when flash use is limited. Can't have blurry pictures or super noisy pictures either. Like I said before, I carry a 24-70 and a 70-200 for weddings and that's what I have used almost purely. They let enough light in so that I dont' have to go crazy with the ISO and gives me enough of a shutter speed to capture that moment. At the receptions I usually don't worry about it since I use external strobes as fill light to light up the rooms so I can shoot low iso, and higher shutter speeds.
As for my photoshoots with models, I like using the 24-70 and my 50mm. With the super creamy bokeh, I'll use the 70-200 for compression.
for you i can understand why carrying as less a possible best suits your needs... you are always moving and can't afford to be changing lenses just because you feel like it... you have to be ready for "that" shot at all times... in your case i would have to bodies with each lens attached to it... to some practice shots prior to adjust camera settings... and just shoot away... anytime i do people shots i take 100's if not 1000's of shots then weed them out later
i shoot photographs for myself... i don't do it for anyone... it's my hobby and i make $0 income from it
i prefer to have it all on me because i do it for fun and that's exactly what it is.
the macro photography is my favorite and most challenging
the wide angle is my favorite for auto's
the fisheye is just a specialty lens that i haven't quite gotten the hang of yet
but the lens that's get's the most action is my 70-300mm... it's my walk around lens
each lens has it's purpose and i try to use them all... i'm into trying all types of photography and not just stuck to one type
hehe i also carry some extra stuff... a spray bottle to shoot down flowers... i make my own rain
a large plastic bag just incase it rains...
a microfiber towel to keep the camera dry...
filters, lens cleaner, etc.... though i do need a rocket blower too...
I will look into the 70-300 VR, thanks for the tip.
i've used both the 18-200mm vr and the 70-300mm vr (which is my most used lens)
i would much prefer the 18-200mm vr... it is supposed to be a better lens...
the only reason i got the 70-300mm vr is because i bought my gf a camera and i got $200 off of the 70-300 and i couldn't justify spending and extra $400 for the 18-200mm... but if you really need that extra 100mm reach then go for the 70-300mm because is is a noticeable difference in reach... but if you want a better quality lens the 18-200mm is better
