50mm Summicron Dual-Range

Recommended Posts

<p>Hey there, I was just wondering if anyone has experience of using one of these on a Leica CL? I picked one up over the weekend (minus the goggles) but it doesn't function properly on any of my Bessas or my M8. My CL isn't with me at the moment... thanks.</p>

<p>I'm talking about normal photography (and I do have it set in the right mode, as you can see from the image...), it mounts but won't turn all the way or properly on the R3A and R4M (gets to about 10m), it will not mount on the Ts at all.</p>

<p>Graham: What, exactly, is the problem? You can't fit it to the camera? Or maybe it does not couple properly to the rangefinder? <br>

@ Alex: Are you thinking the problem is switching in or out of the closeup range? I'm not sure that changing in or out of the closeup range is the problem. It looks like (from his picture) that it is in the normal range.</p>

<p>the lens will mount sucessfully, but the goggles will not. The shutter dial blocks its full mounting on the lens and the window does not line up with the rangefinder window. So you have a fine normal 50mm but are denied the closeup capability. </p>

<p>IIRC, the DR Summicron will not work at all in "close-focus" mode without the eyes attached. There is a ball-baring in the center of where the eyes mount to the lens, which sets the close-focus on the lens.<br>

<br>

Also, FWIW, a DR Summicron will not work properly (unmodified) on an M6 (or later) because it binds against the inside of the camera housing (redesigned for the meter cell). I have no idea about any third-party camera bodies.</p>

<p>Bill, the ball bearing can be depressed very easily, enabling the lens to be focused all the way down. If this is the only mechanical reason then it should be fine to use...? Too be honest, I'm more interested if anyone has used or uses the lens regularly on a CL, this is the only body I own that can potentially handle it...</p>

<p>from Stephen Gandy's Cameraquest site: "The 50/2 DR will probably work fine on the M6, but you must remember to mount and dismount the lens focused at infinity. When focused near it's closest regular focusing distance, the lens will be difficult to mount OR unmount. I have reports of the DR not functioning in close up range on a M6. I am frankly unsure if these reports are due to variations with the bodies and the DR, or are the result of user error. More research will till. It seems prudent to try a DR on your M6 before you buy it. <br>

 

<p>... reports difficulty using a 2nd series DR in close-up range on a M6 .85 # 2296539. While he could mount the lens, if it was not focused at it's closest regular focusing distance, the close up range was inoperative due to some sort of internal body restrictions. Whether this is true of all late M6's in general, or of just the .85 model is not clear at this time. In any case, it's a good idea to try it out to be sure on your own body/lens combination. <br>

The 50/2 DR will NOT work on a Minolta CLE in my experience. Although the lens will mount, it will bind with the body just slightly from the infinity marking."</p>

<p>great info, gentlemen! thanks... i have this one in my closet, too, discouraged from getting a body for it by the conflicting--usually negative--compatibility reports :(<br /><br />so, what <em>will</em> it work on? it was made for the M3, no? how about M2? M4? (i don't have the goggles either, so i'm not worried about the close range)<br /><br />thanks again</p>

<p>Graham: Sorry, but no. The eyes are there to correct the framing /parallax. The biggest issue though is the eyes also adjust the second image in the RF to focus down to 18 inches (or thereabouts). Therefore, if you try to use a camera with a DR Summicron in close-focus mode without the eyes, the result will be an image not framed properly and out of focus.<br>

<br>

And I can assure you it will NOT work properly (unmodified) on an M6 in any mode. Further, AFAIK, the only way to modify a DR Summicron to work on an M6 without binding on the inside of the camera housing is to shave off the close focus cam (then your DR Summicron will not operate in close-focus mode).<br>

<br>

It has been said by others that one could use a DR Summicron on an M8 ONLY on close focus mode (of course this means the stabilizing arm on the back of the eyes would have to be snapped off). But I have not tested this myself.</p>

<p><em>Graham: Sorry, but no. The eyes are there to correct the framing /parallax.</em> <br /> <br /> I meant about there being no mechanical reason why one cannot take a photograph without the eyes, not one cannot focus or frame, those two are always guesswork on a rangefinder anyway ;-)<br>

Actually, I very much enjoy using my Bessa L, and that isn't even a rangefinder!</p>
