Need to get a 645 lens repaired (focusing ring is sticky getting close to infinity) in the UK.
Got a quote of £227 incl VAT (+20% for expedited service + another £120 for full service) from Sendean Cameras in London. Harrow doesn't do 645. Official Pentax place weren't too helpful and simply warned that they might have to send the lens back to Japan. One of the companies I spoke to (AM Technical I think) recommended GRES:
GRES - Professional Camera Repairs
Was very helpful on the phone though warned that spare parts might be an issue. Anyone had any experience of GRES? He reckoned that he would be a lot cheaper than Sendean.
