Duel range Leica 50mm f/2 Summicron

Ziplo

any ching know which metered M body can use the DR Summicron without the modification of the lens?

as far as i know...The MP3 and M6J cannot....but the MP hammertone would work with it....any ching know which metered M body can use the DR Summicron without the modification of the lens?

Why those two cannot ?

Hello k San...

I have no idea... U can mount the lens on...but u cannot turn the focus barrel

Which metered M body you are using? You know there is a small button on top and you need to press it first then you can turn close focus...
sorry not fully understand your problem yet, and some say you can only use/turn in between 2m to 4m range only
I'm using M6 TTL without any problem on close range and normal focus range

I found DR can't work with my BP MP. There are lots of information out there and here is what one expert said (look at the compatability section)

Not everything true, DR does work on my M6TTL, both close focus and normal range without touching the film camber. To use the attachment eye, remove the black rubber bit for TTL model, you can see my film photos are well on focus

Thank you Ching for the reminder...I also aware that that little button has to be pressed before installing the close range glasses...just that while u use the model as I states above...u can only mount the lens on but u cannot turn the focus barrel as if it is blocked by something inside ...interestingly... Both range would work with the hammertone mp...

Thank you M3fan Ching for the information

Could it be that the eye-glass is not from the same batch of the lens barrel,
so that the button is not effectively pressed down even after installing the eye-glass,
hence barrel cannot turn IN CLOSE RANGE.
But the normal range should be OK, independent of whether the button is pressed down or not.

The reason that M8 cannot use DR at the normal range is that it's "black hole" is smaller than film Ms ... like this ...

Just tried a DR on these four film Ms (MP3, M6J, M7, & MP Hammertone)
ALL works fine, both normal and close ranges

But one thing I didn't notice before
the DR can be mounted when set to close range, as well as to the normal range while set at infinity.

But if left the lens at the closest distance of normal range, i could not mount the lens in all four cameras ?!
Anybody knows why?

There are some small differences at the rangefinder coupling vs M3.
Difficult to describe with words, best is to see it yourself.
To see this clearly, open the back of the camera and hold down shutter at B while inserting the lens to play around. Compare this with the M3.
Highly suggested to take a look this way to see how it works on the M3 inside, it is a beautiful piece of mechanics.

Are you talking about current version of MP?

I have one BP s/n 298xxxx. My DR s/n 196xxxx works perfectly on it.

bubu

K-san, I don't get you.

bubu

Yes, when I set the focus at the nearest of the normal range which is 1m distance, I can still mount the lens on current MP.

bubu

Regarding to my MM (I suppose it works the same with M9/M9P) ,
The normal range can only reach 5m far which is expected. Practically it's good enough for portraiture shooting.

When adding the eye for close range, one can unscrew and take away the black plastic catch so that the eye can be fully attached to the body.
But, if you don't bother to do that, the eye can still be added on, only leaving a gap between the camera and the eye and you still can focus accurately.

bubu

The close-up is focused on the eye to the right of picture and it's at f/2.

I tilted up to shoot because the painting is above my head.

bubu

I first thought leaving a gap between the eye and the camera would affect focusing accuracy but...

Here is another one that's 100% spot on.

Sorry for being lazy on writing details and causing confusions
My MP is the current version, one that requires a battery. When I mentioned "can't work", I actually meant the DR is not working exactly as it is originally created, i.e. on M3.
On M3,
1. DR can be switched smoothly to close focus and back when mounted on the camera
2. the lens can be mounted at any positions without problem
3. the goggle position is perfect, except when the goggle version is not matching the lens
4. the lens automatically locks at infinity end (right side) of the dovetail until the focus ring is pulled up (for switching to close focus) or the goggle release button is press

On the MP, I cannot switch to close focus when the lens is mounted. Same as ksan, cannot mount the lens at certain positions. The problem is not enough room to pass the higher close-focusing-cam at the rangefinder coupling roller. Same for many other M models. Some models do not allow the use of close focus while others can't position the google perfectly without making alternations. But most can still take pictures one way or another. Just not the same as original....I am so yim jim

Thanks M3fans c hing!
Just tested DR on M3 & M2, no problem at all.

Toke a few shots on the "black holes" of M6, MP, M3, & M2 for your comparison ...
Obviously the space for lens petpet is much larger in M2 & M3, as compared to M6 & MP
