I recently mounted this classic on my NEX-5 to gain a fast and small normal lens, not quite a pancake, but still smaller than my M4/3 with 20mm lens.

The 30mm f1.9 gives an effective focal length of 45mm - very useful !

Any guesses as to its origins?

Cheers, R

First, I thought it was taken from a PEN camera...
Is the adaptation a DIY job?

Looks great on the NEX!

Oh, and it was not hard. Smile



I only hope the poor EYE was broken without redemption...

Excellent ludoo!

The Konica EYE I used was dented and bruised; an interesting camera for a museum with very dim lighting - but nonfunctional. Fortunately, the lens was in excellent shape!

I dismantled the camera, and adapted it for the NEX using a NEX-LTM adapter. This required substantial use of a Dremel tool, to shrink the plate that the lens mounts onto, and to shrink the aperture assembly to fit the mount. Finally, the adapter needed to be ground down to achieve infinity focus; that is why you see a silver front surface.

The lens is sharp and has excellent coverage; I compared it to a Super Takumar 35mm f2, and it is as good in sharpness and contrast wide open.

Thanks for the tips, and congratulations for a well done job!

Your efforts made me take out of a drawer the lens I salvaged from a Trip35, I just finished removing all the extra crud, and will try to find a way to do the same. It will make a nice -- though less fast -- 60mm on my NX10.

Thanks - the lens has only left my NEX for a few minutes since I adapted it - to compare to a Super Takumar M42 35/2, which is 3x longer with adapter!

Hi, nice to hear from you. The little girl is mine, and the boy is a friend of hers who is getting a hug for his 6th birthday!

By the way, I found a replacement front lens for the Summarit, and fixed the rough focus, and now it's superb! I hope you are enjoying the Rollei!

yeah with NEX summarit is great combo. the rollei is really nice. I fixed focus to get infinity on EOS too. it's easy, just unscrew, adjust focus then screw it again.

Great work indeed! Looks superb Smile I have a bunch of old yet fast lenses from broken rangefinders, and I just haven't got round to doing what you have. Really impressed!

Very nice. I just stripped the 2.8/45 Zuiko from a battered Oly Trip 35 to do the same thing with, I also have a Schneider Reomar 2.8/45 from a broken Retinette to mount up for use on my NEX, seeing this thread just made me realise I need to hurry up and get em mounted, nice work, thanks for sharing.

My sincere congratulations, excellent work!.
I had thought on doing the same with some old rangefinder lenses, but never ended doing it.
(I also got a Trip 35 lens disassembled).
Your work will be inspiring to some of us Wink
Thanks for sharing.

Regards.
Jes.

This was my first attempt with the Olympus Trip lens, from a while back. Wish I'd built a proper adapter now!

Olympus Trip is less good than Konica , Konica is pretty common on USA Ebay.
