Leica Elmar-r 100mm

So I've managed to get a shot of the above lens. Seems to be in very good condition, and tho I've yet to take images of the camera, I'm sure the shots I've taken are going to be good.
I'm using a k&f adapter for m4/3 and it seems to be an excellent fit.

But...

For some reason I can't focus on objects far away. I can only get in focus objects from a couple of feet away up to maybe 20 feet or so. I can't get my back fence in focus from our kitchen window and its maybe at most 15 or 20 yards from the window.

Any idea why this might be?

It doesn't feel damaged, or as though there's an issue with it, the lens seems to travel well when focussing and its seems to have a lot of scope to fine tune focus but just doesn't have the extra bit of turn required to get further objects focused. Is the adaptor incorrect or something? I know my father has an issue with a lens where it zooms but only half the distance it should due to a grub screw sticking out somewhere and stopping the lens. This doesn't feel like the same issue.

Any ideas?

Re: Leica Elmar-r 100mm

Do you have access to a micrometer or accurate digital caliper?
If so measure the thickness of your adaptor. According to this list mFT register is 19.25mm and Leica R is 47mm, so I'd expect the difference to be the thickness of the adaptor. i.e. 27.75mm.
Any more than that and it will be acting as a thin extension tube as well as a mount adaptor.

Do a bit of double checking on the measurements though, rather than just taking my word for it. This Wiki

Re: Leica Elmar-r 100mm

Dont' have digital calipers, but do have a ruler - and it looks like your number is right, going by eye.

I've checked the lens, and it is indeed stopping at bang on the infinity symbol on the markings, so it looks like the lens is doing what it should, to an extent...

To mix my units, even 1/2mm out would be enough to cause an issue.
I've had this before with Chinese adaptors, though in my case it was too thin so a very thin shim was inserted behind the front mount to take it up to size.

Re: Leica Elmar-r 100mm

Got you - even 1mm out would have an impact - it's already quite a tight fit on the camera though - not sure if a shim would help at all. The adaptor seems quite well made though, apart from this massive issue. May have to send the adaptor back and try something else...

Re: Leica Elmar-r 100mm

Yes Ludwig, I was talking about length, rather than diameter, and 1mm might well be enough to prevent infinity focus.
In your case though, if that is the issue, adding a shim would make it even worse, as it would make the adaptor even longer.
Would you have a friend with some measuring gear? Alternatively Aldi/Lidl often have callipers in for less than a tenner. There're not spectacular, but they do the job. Unfortunately there's none currently on offer at either, unless they have any old stock.
Are you on good terms with any car repairers/engine rebuilders, as they would certainly have some kit to measure it for you.
Off out for a while now, so not ignoring you if I don't reply.

Re: Leica Elmar-r 100mm

Ok doke. I have a feeling my partners dad may have a set of callipers. Maybe not digital ones though. I'll ask him when we are visiting today...

Re: Leica Elmar-r 100mm

I had an Elmarit 60mm macro which started to refuse to focus outside of the macro/close-up range. It was a lack of lubricant on the focusing helicoid.

Re: Leica Elmar-r 100mm

This lens of mine hits a hard stop though Harold. It doesn't just tighten up at infinity it rotates to it and makes a hard stop - as if there's a small bolt sticking out to stop it rotating - that kind of thing.

Just making sure the possiblity is covered.

If it was my lens I would find a way of moving the lens (not attached) to various distances from the camera, perhaps with a dark cloth over the gap, to see if it will form an image of a distant scene.

There is a bellows-only variant of the lens!

Micrometer or caliper (be it digital or vernier) doesn't matter, so long as you know how to read it.

Where in the country are you?

Re: Leica Elmar-r 100mm

Are you sure you have the 'infinity focus' version ? The reason I ask is because Leica made two versions of this macro lens, one that will focus to infinity and another that was meant to be mounted on a bellows, if the later it will not focus anywhere near infinity and not everyone is aware of this.

Kind regards, Simon

*** Just noticed 'posts 11 & 12' .... somehow I missed them when replying, as you have the helicoid version I would suspect the adapter is at fault.***
