Infinity focus?

I couldn't focus some of my lenses on my M10 so I gave them in for adjustment alongwith the body

 

Im out for a walk with my second M10 and just noticed it doesn't reach infinity either

 

I've been using these same lenses on my M240 and SL for a long time without any issues

 

What are the chances that some M10's don't reach infinity!?

 

What about your M10's? Infinity OK?

I fear I don't understand what you mean by "it doesn't reach infinity".

 

Is the focussing throw of you lens blocked before you can focus on infinity? Or doesn't the rangefinder show you a precise picture if you focus on infinity? Or are your pictures unsharp after you focussed on infinity?

My bad, I wasn't clear - the RF patch doesn't align at infinity even though the distance scale is at infinity

 

I just got back home, will post some samples to see if pictures are unsharp at infinity

A quick question.......

 

When you rotate the focus ring all the way to the hard stop does the focus patch show out of focus and if you rotate it back just slightly does it then show the focus patch in focus?

The focus patch doesn't align at infinity, it stops before ...  not possible to check what you suggested above unfortunately

Uploaded a sample to Flickr so it can be viewed at a higher resolution - to me, it appears not to be sharp. What do you think?

 

Shot at f16/180s, focused at infinity

Anybody else notice their M10 not reach infinity?

Unfortunately the M/L adaptor is shimmed to allow focus past infinity so it can't be used as an accurate gauge of infinity focus.

 

The image you posted doesn't look sharp to me but Flick could be to blame.

 

My M10 is spot on with all my lenses. So is my M240, although that one needed calibration a while back.

 

It's hard to say which is out. But that shot doesn't look right. (And you need to make sure it's not DOF helping so a test wide open is required, really). Unfortunately I think all you can do is wait until your camera/lenses come back and then test them on your other body. I assume you're going directly to Leica and not a third party?

A classic case of the traditional small twist with the Allen key. Ten seconds max :)

Unfortunately, that example photograph does not look sharp anywhere, so it is hard to tell what is happening.

If the sample shot was wide open and sharp I'd totally agree with you. But that image is a bit *off*.

The,reason I ask is I have several lenses that hit the hard stop just past infinity focus. I also have some that are dead on at the stop. The ones that go,past take a little getting used to.

Yes, but the description of the problem is highly suggestive. Adjusting the roller properly can never harm.

I have sold my M240 (with some regrets now) with the view to get M10, reading of all the problem that people are having with rangefinder alignments would you gentleman recommend that I get a SL that is reportedly much easier to focus using M lenses via adapter? I have no interest to buy any SL lenses. M lenses only.

You should buy an SL if you favour TTL type viewing. If you favour  RF type viewing you should buy an M10.

 

The difference is thus: looking through an EVF (or a reflex viewfinder for that matter), you are looking at the image you are taking.

If you look through an RF type viewfinder, you are watching the scene you are capturing.

All other considerations are secondary.

 

Having said that, calibration is not a problem with the vast majority of rangefinder cameras and for the smallish number that does need some adjustment, the issue can be resolved speedily and at no great cost.

 

Personally, I would not be able to resist buying the native lenses of any camera system I would acquire., even if there is an option to use other lenses.

I wouldn't let potential problems with calibration deter you.

 

Put it this way, which would you want assuming there are no problems with RF calibration?

 

As for focusing, M10 RF is said to be easier than M240 and you still have the option of a very capable EVF, just not quite as capable as the SLs.

 

I'd consider strongly the potential differences in the sensor and results also.

 

On the other side, if you're really not a fan of "retro" RF focusing, found it frustrating or difficult on the M240 and have no particular interest or patience to master it then the SL is probably a better option.

 

M is the iconic Leica design and I think Ms will hold their value better. SL is a more results-focused offering.

What is the lens, what focal length? With such an aperture of f / 16 diffraction appears. With such an aperture depth of field it is so large that everything should be sharp. Perhaps the camera was unstable, maybe the lens is not calibrated. Was this photo taken on a tripod?

Hi Simon,

Thanks for your reply to my dilemma in deciding between M10 or SL. I could say that by now I am quite comfortable using rangefinder cameras and its focusing. I have progressed from Bessa R2A to Zeiss Ikon with the best viewfinder of any rangefinder camera by far to Leica M9, to M9P and then to M240 all now sold. For the last 6 month I have been using a Fujifilm X-Pro2 and to love its hybrid viewfinder and EVF that me got more interested in Leica SL. So right now it is a SL, but that might change tomorrow given M10’s size and a Visoflex. In any case I will stay with Leica and wonderful M lenses. The First world problem I take it.

I have the same problem with my summicron-c 40mm. The focus patch doesn't align when the lens reaches infinity. I did not have this problem on 240.

 

On the other hand, noctilux and apo summicron are perfectly calibrated on my M10.

 

I tried to adjust the roller but that didn't help. I think the arm length needs to be adjusted but I didn't want to mess with that.

I just traded my M9-M for an M10-M (also have an M10). I've noticed that my 5 older lenses (60s to 70s) don't quite hit infinity, but my 'newest' (the massive 135 Elmarit from '74, massive 90 Summicron from '86, 50 Summicron from '96, and 28 Elmarit from '91) are spot on. I'm going to do a methodical test, but wanted to mention the problem exists. Question is, can the lens be adapted to the camera
