I have used MPB so many times.
I love Olympus cameras. I love their 'Pro' range of Lenses but cannot afford either new. MPB have sold me three fast prime lenses, two OMD E M1 MkII cameras, batteries and more.
If you cannot afford new, but want the best your money can buy, MPB is the place to buy from. Their descriptions of products are spot on. They deliver on time. I wont go anywhere else.
