What would be the most useful & convenient zoom lens(es) to obtain (in terms of focal length) for shooting indoors inside the house (lighting could be poor at night) & at the small backyard at the house PLUS I go out to larger dog park fields? I am shooting our pet dogs that move around quick. I have been considering the Nikon 18-200mm VR as a convinient all-in-one walkaround lens because I shoot at a short distance indoors, and at the dog parks in a further distance outdoors. Now I started thinking maybe the extended zoom range is less practical to always be carrying around at the house (at the expense of image sharpness), and maybe I should get 2 separate lenses for the house use (indoor & backyard) and for the outdoor park use with an extended zoom range separetely, so I could get faster lenses if that's a better idea. I am probably using the lenses on a Nikon D90 when I purchase them together, and I'd really want the VR feature. Or getting one Nikon 18-200mm VR more appropriate? I always get great answers at the forum and I appreciate all of you here. Thank you.
