RE: M50/1.4 fungus remedies?

2002-08-03 Thread John Meyer

Hi all,

This has been a useful discussion.  On cleaning an old lense today, I
discovered some fungus.

The now is, how do you pull the lense apart to clean it?

Any tips and pointers appreciated

Cheers

John

 No calibration needed. Take it apart in a methodical way and put it back
in
 the reverse order. Work on sheets of clean laser printer paper on top of a
 couple of pieces of paper towel. Can you remove and replace a camera body
 screw without changing the shape or appearance of the screw-head? If this
is
 true you can probably dismantle and reassemble a lens.

 And I said before it is wise to avoid scrubbing the glass with lens
cleaning
 tissue soaked in 'optical cleaning fluids' such as those made by Kaiser
and
 other photo companies. They will spread any oily residue evenly all over
the
 glass surface. Just use soap and water then get rid of it.

 Of course if you are a stone-mason, or a cello player, your hands might be
a
 bit rough and then you'd have to be careful about cleaning the elements
with
 fingers. The coating is rather delicate and can easily be scratched. But,
 believe it or not, it would take a lot of scratching to degrade the
 performance of the lens so you'd notice. Keep tools and fingers away from
 the diaphragm.

 In Africa fungi grow on camera lenses like crazy. After cleaning them I
put
 the lens barrel and all the other metal parts in a lab dissector in which
 there was a small beaker containing a solution of formaldehyde. The vapour
 killed any remains spores and hyphae lurking there and ready to start
 growing as soon as the lens was put back together. I don't recommend
 formalin. It's nasty stuff and we know a lot more about it now than we did
 in those days.

It depends where the fungus is, and how much damage is done. If fungus is on
the front element, it can be removed with a partial disassembly. I had a
lens cleaned by a pro, and results are great.

Hi,

Firstly, thanks to all for the tips on the Leica. It turned out to have
a messed up shutter (1sec varied between 1 and 2 seconds, and above 125
the shutter didn't fully open). I'm waiting for a quote on a CLA before
I put my cash into it. Oh, and the lens had fungus.

Speaking of which, the shop had a lovely M50/1.4  (or maybe a K -- don't
know how to tell them apart, but it wasn't an A. Minimum focus was
0.48m, and there were 8 aperture blades - the casing felt like plastic
over metal). I had a quick try on their MZ-5n body and I was very
impressed.

I know these questions come up occasionally, so here are some answers to
look up in future:

- Auto-focus confirmation works (!!) - I was surprised at this, but I
suppose there's no reason why it wouldn't.
- The metering seems to work fine. I couldn't be entirely sure, but I
think spot and centre-weighted metering both work.
- The focus feel is fantastic ;-)

... so, why don't I have a nice 50/1.4 now? Well, it had not one but two
tiny fungal colonies.

Does anyone know how to get rid of these, or is the lens doomed forever?

--
Kristian

PS. The shop had actually received, and sold, a Contax N Digital, so
there must me some around somewhere. Price was €9500, but I think that
was with two zoom lenses. Can you imagine Pentax trying to get that kind
of money for a body?

 I haven't had a Leica to play with for a long time but I suspect that the
shutter not fully opening at speeds above 1/125th is normal. 

Now that I think about it it makes perfect sense - since Leica's flash sync
is 1/55, the shutter won't fully open at times faster than this.

I read somewhere that if you fumigate the lens with Thymol it will kill the
fungus. I had a Tokina 24-40 f2.8 zoom that developed fungus and tried this
- I don't know if it worked. The fungus was still there, but I could not
tell if it was dead or alive. After a couple of months in a coffee can with
thymol crystals, the lens sure did smell like thyme though.

I bought my thymol from a chemical supply house.

 Hi,
 
 Firstly, thanks to all for the tips on the Leica. It turned out to have a
 messed up shutter (1sec varied between 1 and 2 seconds, and above 125 the
 shutter didn't fully open). I'm waiting for a quote on a CLA before I put
 my cash into it. Oh, and the lens had fungus.
 
 Speaking of which, the shop had a lovely M50/1.4  (or maybe a K -- don't
 know how to tell them apart, but it wasn't an A. Minimum focus was 0.48m,
 and there were 8 aperture blades - the casing felt like plastic over
 metal). I had a quick try on their MZ-5n body and I was very impressed.
 
 I know these questions come up occasionally, so here are some answers to
 look up in future:
 
 - Auto-focus confirmation works (!!) - I was surprised at this, but I
 suppose there's no reason why it wouldn't.
 - The metering seems to work fine. I couldn't be entirely sure, but I
 think spot and centre-weighted metering both work.
 - The focus feel is fantastic ;-)
 
 ... so, why don't I have a nice 50/1.4 now? Well, it had not one but two
 tiny fungal colonies.
 
 Does anyone know how to get rid of these, or is the lens doomed forever?

 PS. The shop had actually received, and sold, a Contax N Digital, so there
 must me some around somewhere. Price was €9500, but I think that was with
 two zoom lenses. Can you imagine Pentax trying to get that kind of money
 for a body?
