Sorry, this is nonsense. Any technician will calibrate the system to the common standard. Otherwise one could not use another lens or body on it.
In fact, nowadays technicians will use an M240 body and EVF to adjust lenses. Will van Manen told me he finds that even more exact than his 60 cm Collimator, and the 240 costs a lot less.
The mechanism on the 240 has not changed, except for the vertical adjustment which as a more stable hex screw.
Leica asks customers to send the whole system as well. For two reasons: they do not trust the diagnosis by the customer and in some cases they will do tolerance matching.
The adjustment by Leica is not “done by a machine” It is a manual process....
jaapv - You're always jumping on the forums slinging facts with such vigour. I don't always agree with what you say, but it's fun to read your declarations.
Today because you're twisting my words to try and prove a point I'll chime in again.
First to clarify, you're saying what I said is nonsense. But then you reiterate exactly what I said. To clarify I said that by adjusting the lenses to suit a misaligned body, you're creating problems. I didn't get into details, but I'm sure you can dream up all the problems associated with funny calibrated lenses. So we both agree on something, why is that nonsense? Just trying to discredit me? Or do you not think people who service Leica gear would be so irresponsible?
Next you said technicians will use an M240 body and EVF to adjust lenses.. Sure, you can do that with or without EVF... BTW nobody said you couldn't adjust the lens to begin with, especially not me. But that's assuming the M240 has been adjusted to factory specs. What if the M240 is off? Then you're adjusting lenses to fit a defective body. Which is what I don't agree with. Which is what will cause problems, which is what I said in my earlier post.
Now, a machine does the adjusting to factory specs. I was told this directly by more then one person at Leica Germany. If someone at Leica is lying to me. Or misunderstood my questions about RF calibration, then that's fine. But I did put the disclaimer "AFAIK from what I was told by Leica".
If you're telling me that they ask for all your gear because they don't trust the user and also because they want to do tolerance adjustments to lenses and camera bodies. Then why is it that sometimes I just send in my M240s and sometimes I send in only my lenses. Other times I send everything in? How come when I send a 50 Noctilux in with my M240 and it comes back perfect, the lens will also work with my other 3 M240 bodies?
Why is it that I have 4 M240 bodies that work perfectly with all my lenses. But sometimes one of my bodies will fall out of alignment and work with none, and all I have to do is send the body into Leica and it comes back working with all my lenses?
Simple answer. There is a baseline that works 99% of the time. Leica now uses a machine to adjust the M240 for that baseline. The tolerances have changed on the RF mechanism, they can reach the baseline more accurately now (less +/- tolerance adjustments). And the RF mechanism is a bit more durable, shouldn't fail as often.
Now, when the baseline adjustment doesn't work. They'll probably have to do a bit of fiddling. Usually though, the baseline works.
Anyway, ask Leica how they adjust the RF in the M240. It doesn't matter though, my point still holds true. If the M240 cannot be adjusted by hand accurately to its baseline. Then you have to adjust the lenses to suit a non-baseline camera. And that causes problems for everyone. There is no nonsense in that statement.

I was only bewildered by DAG being able to work with M240 cameras, as when I spoke with Leica on one of the two/three occasions it came up in conversation, I asked if I could buy one of those RF M240 calibration machines. I was told no, and that it was prohibitively expensive to manufacture. Therefore not something they'd consider selling. I was also told on another occasion that the M240 needs to be set to baseline in Germany, and that lenses can be adjusted anywhere Leica has a service centre (if the lens is the problem).
Which again, begs my question. If the OP has a misaligned camera, and his lenses are fine. Then will DAG adjust the lenses to suit the off-baseline camera body? If so... That's ridiculous.
If DAG can reset the M240 to baseline.. Then no worries. But as far as I've been told by Leica, you can't do it accurately without a machine.
