what's the external (silver color) material on a collapsible Industar-22?

OK, here is an idea for you that would be temporary: spray-can camouflage paint meant for hunting bows and rifles. It is not meant to be permanent, but will last most of a season. Argentina has good hunting. Perhaps a sporting goods store can help you with that.
If you already have this I-22, and do not plan to collapse it, you definitely could use camo tape on the barrel; it can be had in camo patterns, and in solid colors such as olive drab and black, IIRC ...
 
Several home baked coatings typically meant for firearms are available. Bake-on Teflon coatings are highly regarded. The stuff sticks to stainless steel, so it just might stick to chrome that has been mildly roughened to help the compound adhere. Here is one company's web site: www.blackicecoatings.com.
Too bad your heart is set on the collapsible I-22 ...

Long ago I was with a group who found bits of a plane that had crashed in the fifties. In a totally wrecked engine were beautifully shiny, un-corroded chrome tappets . . . and this after (then) forty years under an acidic peat bog. Admittedly that was probably very good quality chrome, but there was a dramatic difference to the rest of the alloy and steel parts !

Even if you could paint the collapsible lens it would then be too thick to retract. How about doing something 'horrible' with a normal alloy Industar-50, or an I-61, instead ?

Interesting story, Martin... Damn chrome! :) Well, I was thinking of that IIIC for pocket use (collapsed), and for sun with Tri-X, so to use the lens at f/8 and avoid any possible focus shift... But all voices are saying don't change chrome, and they seem right unfortunately...

OK, boy was I wrong about the I-22 ... :(

Looks like you will have to go rigid. But if you go rigid, black versions of the I-50 and J-8 already exist.
So, why collapsible? Are you trying to get the most compact package?

Hi Paul, yes, the small and especially flat package was all I wanted, and my only reason to get a Barnack... After at least ten comments from people who owned both the elmar and the industar and preferred the industar, I decided to give it a try... I read there's more sample variation in other Russian lenses, maybe newer and faster ones... Seller (Russia) confirmed the lens is like new, without scratches, fungus, haze, etc... I think more than a camera I was looking for a new toy to play with: painting, fix possible problems, enjoy mechanics... I won't give up easily... :D

Cheers,

Juan

Might you tell us more about your project?

Sure... I plan to collapse the lens (constantly) just to carry the camera, and while shooting surely I won't collapse it for the rest of the shooting day...

I will use it with the lens stopped down to f/8-f/11 both under the sun and on overcast, with Tri-X and TMZ, for easier and faster focusing, or even prefocusing for not very close subjects... I guess I'll use it mostly for sunny scenes to have a second sunny lens/camera (longer FL) while I use my 28 3.5 on my R4M. For shadows and overcast, the 40 1.4 on my R3A is great because it can be used quickly for any light condition...

I prefer black or olive finish just because silver is more noticeable... Your idea about painting camera/lens with olive paint for rifles would make me very happy, more than black... Maybe I could do it, and for sure I wouldn't care if some paint goes away sometimes: it would be part of the fun and I would enjoy painting a bit again some other day... I'd like to do it manually with brush and avoid sprays and masking... I don't want it to have a factory look... Maybe you know if a product between chroming and rifle paint could be a good idea to make the paint a bit stronger on surface: I think paint directly on chrome is a very bad idea... It's a shame I know nothing about paint: I have never painted anything in my life... Any recommendation about a convenient olive or dark green paint, and maybe a previous "painting" or base, would be very helpful...

Cheers,

Juan

Sounds like fun Juan! Hope you'll post the results.
I'm sure you know about the different rangefinder register between the FSUs and the Leica Standard... I guess at f8 you'd be ok :)

Hi Alex,

Nice thread, thanks! I didn't see it before... I've heard of that rangefinder register difference many times... What I don't understand is why some people say they get (and show examples) well focused shots with the collapsible I-22 even at 3.5 on Leicas... Are I-22s that different ones from others?

If mine has serious problems to be focused, I'll be needing help from a professional because I have never opened any lens or camera... I guess all this will be part of the game... I doubt someone could do it here in Spain, so it would mean months...

One thing I honestly did not consider before I ordered the I-22, is -as someone else said- maybe even paint would make the barrel too thick to collapse... Is the barrel size THAT precise? Could the collapsing produce traces of paint giving internal problems? LOL, now it looks like all I thought was wrong and is not possible...

Cheers,

Juan

It is a matter of shimming. Brian can advise you on that ...

Here is another idea for the shiny chrome barrel: rather than paint it, just carry an olive or other matte-colored ponytail scrunchee. Slip that over the lens front and onto the barrel. Presto, no more shine!
 
The story began like this: a few days ago I thought "I have 12 cameras I use. I need nothing. But I want a small Barnack to paint it black and carry it with its lens collapsed..." Then reading about the collapsible elmar 50 3.5 I found lots of good comments about the collapsible I-22... Then I ebay-searched yellow filter Industar-22 to see if the lens could be filtered, and one Russian filter was offered, so I thought: "if I don't buy this filter right now, I will never buy the lens, and without the lens I'll never buy the Barnack I've wanted for long... So it's clear buying this filter is important...", so I ordered the filter! Yesterday I discovered it was the wrong filter! It was indeed for the Industar-22, but for a rigid one I had never heard of! Now all my painting plans are in serious danger and all I've got by now is focusing problems... Mmmmmmm... Looks like if I was looking for new toys and new problems to solve, I'm right on my way...

Cheers,

Juan

Wrap a skinny one 2-3 times around the barrel; easy on, easy off ...

You're being great help... I think I should find out what base to use on chrome before paint (or enamel), and just use it and then paint camera and lens knowing it will require eternal retouching... That's an easy and fast way to get an olive Barnack... And maybe my twins could enjoy painting when they grow a bit... Now they're less than two years old and I guess they'd "coat" the lens olive green... :D

Cheers,

Juan

The I-22 is an f/3.5 lens, so it has enough depth of field to cover the error in focus for most situations, even wide open. I have several I-22s and I've used them all on my IIIC without any obvious problems.

You might be lucky or unlucky with yours but there's a fair chance it'll work fine.

By the way, just a thought - if you could get some shrink-tube of large diameter, maybe you could cover the barrel with that? The lens front is quite easy to remove in order to do it. I'm not sure if it would stand the thickness and still collapse though. Or how about one of the thin stick-on fabrics (in the UK we had/have one called Fablon). Some of them might be thin enough.

Oh, it would be great not having focusing issues!

I'm reading on motorcycle forums: looks like there are products to be used directly on chrome (two-part bases: primers with zinc chromate) and then you can paint... They say there's very good adherence... I'll read more... Now I need to know what kind of paint would be better...

Cheers,

Juan
