"HOW TO" ??? REMOVE LENSES 28-80 QUANTARAY
HELLO ALL, THIS IS MY FIRST THREAD. I AM TRYING TO DO WHAT SEEMS
TO BE THE NEAR IMPOSSIBLE, DISSASSEMBLE A QUANTARAY LENS TO SEE
IF I CAN CLEAN THE LENS OF FUNGUS; YIKES WHAT A BEAST !!!!
CAN ANYONE SPEAK FROM EXPERIENCE TO OFFER ME A STEP BY STEP.
I KNOW THE CHANCES ARE SLIM BUT I PREFER TO LEARN HOW TO DO THIS
PROCEDURE MYSELF. THANKS JIM
NEVER DO THIS TO A LENS YOU LOVE IF YOU HAVE NEVER DONE THIS BEFORE! Can't stress that enough.
I can't offer step by step, but I have taken a couple of fixed focal length lenses down and cleaned them and reassembled and they worked fine except for one thing. Watch out for the little ball bearing and the spring that creates the click as you turn the aperture ring. This is located in a little recess in the inner housing of the lens behind the aperture ring. Second thing, get a set of spanner wrenches before you start. You can get these from eBay cheap enough. These little ditties are priceless and save alot of time of lens scarring do to using the wrong tools. Be careful, use common sense, don't continue past what you are capable of and good luck.

HI CHRISTOPHER, THANKS FOR TAKING THE TIME TO PROVIDE SOME INPUT TO
THIS SUBJECT OF MYSTERIOUS PROPORTIONS. THE INNER SANCTUM OF COMPLEX
ZOOM LENSES SEEMS TO BE A PLACE ONLY FOR THE ANOINTED FEW. SIGMA,
WHICH ONCE MADE QUANTARAY FOR RITZ HAS NO RECORDS FOR PUBLIC USE.
RITZ DID THERE USUAL "I DON'T KNOW" ACT. IF I AM DETERMINED TO KNOW THIS
SUBJECT, IT ALMOST SEEMS SENSIBLE TO GET A "CLEAN" 28-80 ZOOM OF
EQUAL VALUE ON EBAY, AND GO TO WORK ON MINE, AND IF I MESS IT UP, I
WOULD JUST CALL IT THE PRICE OF KNOWLEDGE. THANKS JIM D.
It's a Quantaray lens. It isn't worth the time or money to try and repair. Just replace it. Also, as a separate note, please turn off your caps lock. When you type in all caps, it's as if you were standing next to someone and shouting.
FLYING CAMERA, YOU ARE RIGHT, LESS PAIN. I JUST HAD THE URGE TO
"DO IT MYSELF". RE; UPPER CASE, I CANT READ LOWER, TOO
SMALL. I TYPE, THEN I READ. I'M NOT SHOUTING, REALLY.

That does not work on all computers, mine--but on most browsers if you click on "view" there is a line there for increasing text size.

Never mind, I used logic.

Either replace the lens, or live with the fungus (and are the results so obvious? You may be able to live with it), or send it to an experienced repairman. Essex Camera in New Jersey seems to be able to do almost anything; start with them.
