Oh why am I forced to give them even a 1 star rating??? My choice would be -10, and that's being generous. My experience is reflected in all of the 1 star comments above, but after the way I was gaslit and summarily dismissed in the most patronising and condescending fashion, I somehow suspect that these reviews will not find their way to MPB customer service (if they even have one). So, the best thing I can do, to save future victims, sorry, potential customers, from being similarly ROBBED of the £400+ I paid for a dud lens, is to warn everyone- DO NOT seal with this company, under ANY circumstances....unless you're rich enough to take a hit on your hard-earned £££s. This company is a DISGRACE. If I'd read these reviews above before my ill-advised purchase, I'd be £418 better off. I got a quote for a repair of the lens 2 weeks ago from a different company to make it workable: £355... You can see now, my gathering ire. Still, it's not over just yet as Citizens Advice will be my next call and I'll be searching every avenue of Customer rights to make these b......s pay.
