Sharing this super wide lens on M9 Leica Hologon 15mm f8 ....due to the lens is too close to the CCD red vignetting can't be avoid. However on film M body should be ok.

 

Photo taken last year on my Tibet road trip

 

CornerFix or hand coding the lens might be worth a try.

An amazing collection of old lenses and pictures in this thread. I have used the 15mm Hologon on the M8 and found it OK. Same problems on the M9 as posted. On film Leicas the Hologon is most interesting because it is practically without distortion and very effective when in extremely close quarters. I have used it for b&w negative shots of small Japanese Zen gardens.

This thread shows that not only the latest and greatest lenses produce wonderful images.

A real Hack- from 4 different lenses. The Canon optics module missing the rear elements, focus mount with no optics module, retaining ring, and the rear group from a Nikkor. I could not come up with a rear fixture that would screw into place, so I wrapped the Nikkor fixture with copper tape and screwed it in. I tried a stand-off shim, but it interfered with the aperture closing down. The shim pressed against the mechanism. SO: I ended up getting the rear optic into place, tested close-up and infinity, tested flatness of field, and used JB-Weld to hold in place. Stuffed a foam strip in between the retaining ring and optics to act as a light baffle. These are all left-over parts, and I was curious to what it would all do when put together. AND- when someone on the forum uses the phrase "Canikon", i can reply- "I have one of those."

Well done Dr. Frankenlens!

 

I'm stunned by what you achieved. Honestly I would never have thought of putting together a lens from different ones and different brands but as usual there's always something to learn and to play with. Apart from the obvious mechanical skills this implies you must have solid understanding of lens design. Or it was just "I have this and that, let's try what happens by recombining them"?

 

Cheers,

Bruno

Thankyou. It started out with let's try it, and see what happens. Then look for the reason. On the Frankenlens- formula for combining lenses means you can get the center in focus and everything else is luck. Makes for some interesting effects. Where FL is focal length, D is distance: Effective Focal Length= (FL1*FL2)/(FL1+FL2-D)

M9 + Elmarit Asph 24/2.8. Again, not exactly an oldie but a lens discontinued too soon in the name of God only knows what and on its way to become a sorely missed classic.

Leica M9 + Summaron 35/2.8 goggled (M3 version). An unforgettable classic still not too shabby before its more recent siblings.

Another Hack-Job. Nikkor 10.5cm F2.5 in S-Mount, missing the rear element. Bought off Ebay for $40. Now with a Plano-Convex 103mm optic ordered from Surplusshack for $3. Wide-open on the M9, using a Nikon S-Mount adapter.

Still experimenting with this one, focus is good out to a few meters. focal length is a little off, need to play with the spacing. Telephoto lenses are less forgiving. "But Brian, why not my an M Type 240 and make it easy": NAH! Gotta maintain RF coupling!
