I was cleaning house over the weekend and stumbled upon this lens from my Uncle's estate in a box of stuff. It's about 5" in diameter and 6.5" long and has an aperture ring. 2 elements cemented in front and two elements (air space) in the rear. It has a HUGE image circle with focal length approx 10". The lens also had an extension tube/adapter built for a Rolleiflex SL66.

Anyone have any background on this lens. Googled it and nothing came up.

Here's a photo of this behemoth.

I think that this lens can be easily adapted on Micro 4/3 camera bodies Smile

What do you think, wilson? Smile

No idea, indeed Smile

But thanks to sharing this monster! Smile

Yes it can! That's why they had the tripod mount on the SL66 adapter Wink My GF-1 or 5DMkII can just hang off the back! I'll clean up the lens to see what I can do.

Sounds like a Petzval-type portrait lens. These are normally huge. They were designed for speed and center sharpness.

This is a great article on the subject -

"Cabinet" was a size of print, and on the lens this may have referred to the designed coverage, which seems to have been fairly small in relation to the size of the lens.

There were two "Cabinet" formats, one was 4x4 /12", the other 7x10"

Your lens is likely to be at least 100 years old.

Wow, that's one beast of a lens. When you get around to taking pictures with this lens, be sure to include one that shows this thing on the GF-1. Or the GF-1 on this thing, really…

Thanks for the info. I'm trying to get the lens cleaned up. Unfortunately it's showing signs of age with cleaning marks and some fungus etched on the rear elements. Lucky it's non-coated so makes things easier.

Wow, this is what I call a proper iris (20 blades)!!! Very Happy They don't make them like they used to nowadays.

If the lens doesn't flare a lot, the bokeh should be pretty cool for this large format portrait lens Wink

Got some hints on the converters needed. A friend of mine in Singapore has a SL66 -> Mamiya 645 adapter with helicoid and then a Maniya 645 -> M42 or Canon EF mount. Sourced the latter.

Alex, help on the SL66 -> Mamiya 645 adapter!!

Just got my hands on a SL66 extension tube so they it can be my sacrificial SL66 mount, need to turn a adapter down to M52 so it will fit on Alex's larger helicoid Smile That should do it, and it didn't cost that much Wink

Here's now it looks for now:
