Exchange Panasonic 100-300-for Panasonic 25mm micro four thirds

Hi, is anyone within the London or M25 area interested in exchanging a Panasonic 25mm f1.4 for a Panasonic 100-300mm fitted with a tripod collar all in superb condition.

I have checked the current new prices of both lenses which are so close to parity that I assume the used value would also be the same.

If interested please e-mail Raymbanks@sky.com
