Nikon 18-105 F/3.5-5.6 VR
How to say this...........it's not one of Nikon's more expensive lenses; it's definitely not one of Nikon's faster lenses
It's a reasonable solution to a particular segment of the market
Look at it this way...........no two people wanting to buy a lens are in the same circumstances; that fact makes it nearly impossible for anyone to make objective comments about a particular lens, to someone whose circumstances you know absolutely nothing about.
Any F/3.5-5.6 lens is not fast (read: high quality, expensive, etc.)
Will it produce "acceptable" photographs ? it all depends; on many things; ( mostly, the guy with the camera )
With lenses, you pretty much get what you pay for; if you pay a lot, usually you can expect a lot; if you pay less, you should probably expect less.
Ask yourself a few questions..........do you normally take mostly photos on bright, sunny days ? if the answer is yes, a 3.5-5.6 lens may be plenty fast enough; if you plan to take photos on cloudy, not so sunny days, you may need a faster lens.
Having said all that........remember this; after all is said and done, the quality of your pictures will always depend a lot more on what you know about photography, than on what lens you are using.
