I'm looking at getting a Panny 12-35mm. The best deal actually in the UK is from Wex Photographic, £829. However DigitalRev is undercutting this by £240, which is a hell of a chunk of money. DigitalRev do claim that they are paying import duty on their prices, so the only downside is the lens won't have a proper Panasonic warranty, you have to take it to an authorised repairer, get a quote and then DigitalRev say they will pay for the work to be done. I'd like your opinions and experiences on this.
