| A little bit about The Lens Doctor, many people will recognise my name Eddie Houston having played, some years, for famous Rock Groups , Thin Lizzy , Creed and some time with John Coghlan , Status Quo…and of Course Pilot, but my early years were spent learning my trade repairing cameras, photocopiers and lenses with Canon UK, hence my knowledge of Canon equipment. It was through people asking me to repair lenses that I have brought about this shop.
When you purchase one of my lenses, we do not just tighten up Focusing Helicoids and adjust certain movements, Let me explain: The basic movements of a lens acts with the same principals as a piston when you turn the focusing ring the movements of inner parts move and displace air, to and from the lens body. This movement of air attracts fine dust and particles which are not always visible to the naked eye, but some do deposit themselves on to the inner parts of the lens, including the glass elements, and through time build up. If you can imagine what your spectacles would be like if you did not clean them often, hence the accumulation of dust in a lens is an unrecognised major issue producing haze and light scattering very much opposed to what the glass coatings are there to rectify, this before the untrained eye lowers effective contrast, and light transmission thus the lens is less sharp, no matter how effective it was when new.
If you are investing your hard earned monies on a second hand lens, if it has not been serviced you invariably are buying someone’s dust and problems especially older lenses that were not weather proof sealed. At the Lens Doctor, with over 30 years experience, we often see lenses purchased through other re-sellers; frequently fail our Quality Control standards.
I remember a saying my father used to say “ buy cheaply , you buy twice”, our re-furbished lenses are not the cheapest, we spend time making sure every part is checked cleaned set up and presented to you, with every care and detail as it came out of the factory. We offer a no quibble guarantee on all our products, and workmanship.
Our Less Than Perfect Category, some of the older (30 years +) lenses we re-furbish may have some very small exterior body blemishes, we do try to remove all but invariably some may be too deep to remove, we have created a shop category specifically for these lenses, we will stipulate what faults are found on the lens cosmetic / mechanical and list these faults for you, but most importantly it is the inner parts that make a super lens, so all will be fully serviced. Thank you for taking the time to visit my shop.
