Have one of my old favourites to sell, a manual focus Nikon 100mm f/2.8 lens, from the E Series. You can see what Uncle Ken has to say about it here - http://www.kenrockwell.com/nikon/100f28E.htm
The review is absolutely spot on, this will produce some of the sharpest photos possible as long as you don't mind losing the AF function.
The back element has the tiniest threads of spider growth, only possible to view under close inspection and in no way compromises image quality. Only mentioning for completeness and if you are not satisfied I'd offer a complete refund minus our postage costs.
As someone with lenses ranging from the £30 mark to over £3000 (Nikon 300mm f/2.8)
, I can promise you that this is the best bang for the buck you'll get for £40 delivered. But again, remember that this is manual focus only. You won't have a problem focussing through the viewfinder though. In fact, because you have to, this lens hasn't produced an out-of-focus shot that I can remember. And it extremely good for producing deliberately unusual focussing.
as per my other threads, I will also accept Amazon codes or M&S vouchers in lieu of cash.
