lens paint pealing

Hi Everyone,

 

I have a black 50mm 1.4 asph (production 2002 i think). I bought it used but basically in new condition a year ago.

 

I just notices the paint on the prefocus lines is pealing off. This is the white paint. Is this normal? I don't abuse it to say the least so i was somewhat surprised to see this.

 

thanks!

I'd seek advice from Leica. Any pictures ?

It happens. Causes are sweat on the hands of some users or contamination with DEET in mosquito repellent, it happens more often on cameras than on lenses, though. Leica will happily reapply it for you.

Just usual Leica quality i'm afraid. Suffice it to see how easy it can be to remove Leica paint with a drop of acetone. Took me a good fifteen minutes to remove white paint from a ZM hood recently. Five minutes are enough on Leica hoods usually.

A user in this thread http://www.l-camera-forum.com/leica-forum/leica-m-type-240/271568-m240-black-dot-7.html#post2637434 claims the white letter M could be repainted so this might be the case for the lens as well. You could try it if it bothers you.

Of course it can be repaired. You can even do that in DIY.

Thanks for the advise. I'll have leica touch it when they do a checkup in a few years.

You can buy special 'pens' for this purpose.

This sounds good. Do you perhaps remember the name they go under?

Here's an example:

Perfect, I bought one just in case.

Now I could remove the M, and maybe add a black dot. The only thing missing would be the white plastic mount marks on the lens instead of the red ones.

Technique is to remove ALL the old paint in the letter to be repaired. Rub paint stick over

over engraving, then rub off excess. There will be a fog of white remaining. Wait 24 hours and rub off the fog.

 

Round tooth pick will help with removal.

Many thanks I've ordered some in the UK, only £1.84 each I'll see if I can repaint the buttons on the back of my M-9P

I've just received the stick. It's in a solid form, so I wondered how one uses this.

The instructions read it should be rubbed in, and excesss should be wipped off.

So once rubbed in it will stay there? I expected something in a semi liquid form that would dry once applied.

 

 

I squeezed it with my fingers, and I believe I got it now.

 

I remember I saw in one of the Leica Videos, they used some liquid and than wipped it off. So, this is not the same, but if it serves the purpose I'm fine with it.

You're saying (dilute) DEET strips paint?

 

s-a

Some paints yes. It is definitely harmful to a wide range of plastics.

 

It doesn't strip it. It softens it.

Jeez, I had no idea. Thanks for mentioning that Jaapv! Thanks JD.

Insect repellant containing deet has been known to mess up cameras, handheld gps, binoculars, cell phones, sunglasses, and the like for a while now. A lot of folks found out the hard way.

 

If it will do that to those items it must have some really neat effects on the body too.

Nice to see they use fine paint brushes too. I bought two of the finest brushes for dusting the camera and lens and keep them in my camera bag with the shafts cut down to 50mm, they work very well

DEET is a better paint stripper than some commercial paint strippers. And because it only needs a fine oily residue to work it can get everywhere. Last year in extreme circumstances I used some and even after trying hard to wash it off my hands within five minutes the lettering had been removed from my tripod which had been pristine for eight years. The modern 'black paint' coatings Leica use for the bodies aren't affected because they are powder coated polymers, nor the anodised black of the lenses, but deet affects oil or cellulose based paints which is what the lens makings will be done with.
