Can anyone tell me why I should purchase the nikon 18-300 f3.5-5.6 or f3.5-6.5 vr . I want a superzoom all in one lens and have a d5100 and in the long term intend to purchase a d7100 or newer version. I know all about the iq drop etc. I just want a good travel lens. The problem is in the UK there around the £600 mark with a one year warranty( come on Nikon).
Yet I can purchase the Sigma 18-250 macro for £300 three year warranty DP best lens current time .
So please can anyone tell me why the Nikon as I m willing to spend the extra if it can be proved it's worth while.
