Dual Range Summicron

Recommended Posts

It has the facility, by pulling on the focus ring, to be able to focus down to just under 0.5m. In order for the viewfinder to work, the lens comes with goggles to magnify the image.

Mine is a lovely lens, but unfortunately, is one of those that doesn't work with my M240.

And yes, the M2 does need a jolly good dust...

I used SOMNI with other digital M before M10 for many years.

I happended to buy cheap DR which I butchered filing the rear coupling came clearing focus to infinity.

The only distance I can not use this lens - with RF (+ close-up device) is from 70cm to 90cm.

I put a sticker on the distance ring (0.7 to 0.9 red NO!) as warning.

And what is so special about it?

It is special (compared to the normal rigid Summicron of the same era) only in the close focus range using the adapter. The optics are identical to the normal Summicron (except the actual focal length is selected to match the needs of the adapter), the focusing ring is narrower, and it doesn't have an infinity lock. I have both the close focus and normal versions, and prefer using the normal rigid Summicron.
