You could do a lot worse than :-
Ed Trzoska 150 Harrowgate Drive, of
Euro Photo Services. Leicester, LE4 3GP, England. 0116 267 4247.
if you speak to him his attitude is 'can do'. He only services non digital equipment. He does have a waiting list for his work which tells me he is good and worth waiting for.
He has not worked upon any of my kit but he gave me good advice about a Nikon F about a jammed metering lever in the Photomic head and how to 'un-jam it).
his website is quite small but gives more information than above.
You could also try:- The Camera Repair Workshop. 9 Wharfside, Fenny Stratford, Bletchley, Milton Keynes MK2 2AZ
Phone:
07436 791736.
He is semi retired now but still taking in work. He fully serviced a Minolta XM (Minolta's attempt to rival the Nikon F2a) He did a cracking job even sorting out a damaged spring in the wind on mechanism.
He was also supposed to have acquired all the remaining Minolta spares when Minolta folded after purchase by Sony.
