?? defective M to T adapter?

In topic below I describe erratic F stop info being displayed. 

 

Well I have identified another suspicious anomaly. Sometimes the camera exif data records as "R to M lens adapter" instead of identity of actual R lens

 

The M to T is extremely difficult to attach to the SL body. It takes almost superhuman effort to rotate it until it snaps into place. Also when removing it there is similar extreme difficulty in rotating it off. 

 

In comparison, the Leica R to M adapter smoothly and easily rotates into position on the Leica M to T adapter. 

 

Also for comparison, the Novoflex R to T adapter also smoothly and easily rotates into position on the SL body. 

 

So.....could I have a defective Leica M to T adapter??

 

Your assessment is most welcome.

I leave the M to L adapter always on the camera. So in a way it is a camera with M bayonet for me. (I have no SL lenses, yet).

And I remove it, or put it on when the camera is completely turned off.

 

And regarding your other question: As there is no data exchange the camera has to compare the light from its external sensor to the light coming from the lens onto the internal sensor. With this difference it makes a guess for the aperture.

If your finger is in front of the external sensor your results are wrong. And depending upon the direction you point to (light sources) results can be quite random.

If you want to avoid this, use only SL lenses.

 

You bought a Leica because you "trust" its quality. So why are there so many "believers" that lose faith at the smallest occasion ?

Short: Of course it is possible that an item is defective. But how likely is it (regarding quallty control) ? And how likely it is that the typical users who do not like to read manuals are simply not understanding what's going on and misinterpreting things ?

And of course Leica will react to this sort of complaints, but I wonder how much money is lost that way ...

How about a constructive answer to the legimitate worry of the OP about his/her trouble with this adapter, instead of absurd considerations about 'trust', 'believers' and what not. Leica isn't a religion, you know, even if some behave as if it was.

The OP. thinks that a Leica product might be faulty and asks politely for help and opinions. Therefore, the general tone of your post is absolutely out of place.

Unlikely you have a defective adapter. My M to T adapter is a very smooth fit to my Leica T camera but was a stiff fit to my SL. To improve fitting i applied the tiniest amount of Vaseline to the adapter's bayonet including behind the bayonet - and then wiped it off - which leaves a micro layer still on the metal and is sufficient to reduce the stiffness. Care is needed not to apply to the contacts - use a Q tip - but wipe off with a tissue.  Leica used to recommend Vaseline to lubricate lens and body bayonets - but only a minute amount and to be wiped off after application. My M to T adapter is still a stiff fit but not as stiff as prior to the lube application.

And I think the tone of your answer is absolutely out of place. First think  ...

I gave a clear answer and added some thoughts. You just added nonsense. Not a single line that belongs to this topic.

 

The more I think about your intervention, the more unfriendly I find it. I think you simply should not be allowed to utter such nonsense. And if you do that without thinking of the consequences, at least apologize afterwards.

The F stop reading using the adapter will be erratic versus showing what F stop is being used.  This was something that was added during the last firmware update. Prior to the update we would not get any F stop reading using the adapter.  In terms of the adapter being a bit stiff... I noticed some will be that way and others not.  Unless it is really way too stiff, there is probably nothing really wrong.

Appreciate all help.

The first R Adapter M I received was what I considered way too tight a fit, even with lubrication. I exchanged it for another, which fits properly.

I don't have an SL yet and I haven't seen its M adapter in person, but I know quite a bit about lenses and M-adapters. You do want a bayonet adapter to be "tight", because it wears a little over time and the bayonet "ears" get less springy.

 

The issue is that the M to T adapter has very little metal barrel length to hold on to when attaching it to the camera. Put the adapter on an M-lens first and then use the M-lens as a handle to attach the adapter to the SL. I haven't tried this, but it should work. As the focus tolerances on a wide angle lens are +or- .0003 of an inch, a tight adapter is a good thing. It will loosen slightly over time.

My M to L (T) adaptor fits smoothly and easily. If you're worried about scratching the mount of the camera I would have it checked at your dealer.

 

My M.A.T.E. is very tight to fit to my M. At first it concerned me as it's much harder to attach/detach than any other lens I own. However I have not noticed any damage to the lens or camera body so now accept it as a quirk for that lens. If your adaptor doesn't cause any damage and works OK then I think you'll be OK.

 

With items as expensive as these I think it's natural and correct to ask if there's an issue.

Hi !

Thanks for advice! I will try a minute amount of Vaseline on bayonet of Adapter M-T!

Thanks again!

Yes, but that was before their was a coding sensor built into the mount. Clearly you wouldn't be advocating getting Vaseline onto the sensor, but what you do and what others do without understanding the risks is another thing.

 

The OP should just accept the adapter is a bit stiff and stop trying to fiddle with it, mine is when mounting it on the SL body, never gave it a thought, glad it's tight enough not to let light or water in.
