CANONET QL17 GIII

I learned about the Canonet QL17 GIII from a very
special friend/teacher, and I am so very grateful
for that. Sadly, I have no contact with him and as
a result cannot learn, or ask technical questions anymore.
Does anyone know the best way to clean the lens on
my Canonet QL17? I've heard lens fluid, but which
one?

The best way to see dirt and dust in your lens is to look at a blue light
with it, or inspect it under a blue light...I don't know why it is, but blue
seems to bring out the "best" in dirt....:^)

Yes, that's true about not seeing all the dirt on the surface of the
lens, and prints for that matter. I'm just relieved to know that it
doesn't cause problems. I was told a while back that dust causes
fungus, so I thought I would keep the lens clean as much as possible.
But in doing so, I'd probably cause damage as well. Thanks Bill.

Re: CANONET QL17 GIII

There is dirt on any lens....Even brand new ones straight from the
factory....The question is, how large a particle of dirt does one have to
worry about?...If you get an electron microscope and inspect the surface of
the lens elements with it, you will be horrified. the same thing is true of
your scanned images....If you blow them up far enough, you will see
particles of mould and dust on them, but you can spend your life cleaning
them up from things that will never cause any problems......

The sensor for the meter on the Canonet is located inside the front of
the lens just above the first lens element. *Rumor* has it that any
filter will mess with the metering. I've never had a problem with a
UV. It takes a 48mm filter which is easy to find as any.

Yes a lot of people use UV or skylight filter just for the protection
of the lens, not only to cut out UV rays. The size is hard to find,
but I'm sure one can be found on ebay. Great advice!

Re: CANONET QL17 GIII

Many people will tell you not to use a UV or skylight filter on the
GIII because it will affect the metering, I've found that to not be
true. I keep a good UV filter on my Canonet and the meter works fine.
Never once needed to clean that lens other than the day I bought it.

Lighten up Jeremy! Aren't these newsgroups for people to ask questions
and learn whether they be silly to you or not?
A lot of dirt and particles are invisible to the human eye. I only
thought of the lens needing an occasional cleaning due to this.

Re: CANONET QL17 GIII

You just "thought" it should be cleaned "sometimes?" But you don't see any
"dirt" on it?
Are we in the Twilight Zone, or what?

Re: CANONET QL17 GIII

Thank you kindly for your advice. In all honesty, I'm a little nervous
to use Windex or any other chemicals on the lens. I thought it might
destroy the coating.
I'm probably just being too paranoid.......lol.
Thanks again.
