I am of course talking about my Nikon 18-200mm f/3.5-5.6 G VR DX Zoom Nikkor Lens.
The vast majority of photos you’ve seen on this site have been taken with the same lens. The 18-200mm VR Nikon lens is probably the most versatile lens in the world. It can take reasonable wide angle shots as well as zoom up to 200mm. When ever I go out for the day, I know I’ll have a 95% chance of dealing with whatever I come across with this lens.
