Thanks. I recently bought here an M mount Zeiss 45/2. i fon't want any other G lens in M mount. I have a Tessar 50/2.8 ltm that was originally in Pentax mount, and I have Zeiss Sonnar 50/1.5 ltm.
Are you still using hacked lenses?

I don't have any hacked lenses at the moment, but would love to have a 45mm 1.7 Yashinon from the Yashica GSN for my M3. And a 40mm 2.4 Summarit from the Leica Minilux, as well. Alas, I'm too cheap to cough up the bucks.

As a confirmed experimenter I am doomed to always use hacked lenses. Not for everything but quite often. Sometimes the results surprise me and rise above the mediocre.
Oh wait....
Correction; the mediocre results are most likely the operator and not the equipment.

My first hacked lens was a 40mm f11 single element plastic lens from a Kodak Instamatic 124 (126 cartridge camera) mounted to a Olympus Pen F. Worked about as well as could be expected. That was around 1973.

I never said I was confused.... Just worried my answer to the poll would give the wrong impression. I really want a hacked lens!
The fact I haven't (yet) used a hacked lens, doesn't mean I don't want to. I actually thought about sending my Zeiss 50/1.8 QBM lens to Amadeo to be "hacked" to M mount. I used to have the Rollei QBM system, but sold most of it to fund an M8..... back in the day.
That Zeiss (true German Zeiss, not the Singapore Rollei version) QBM 50/1.8 is a real stunner. In a roundabout way, that lens is responsible for my plunge into RF and Leica....I will attend rehab someday 🙂

Hi Raid,
I used a simple Leica M body cap I had bought cheaply from ebay. If converting to Leica M the lens has to be 'recessed into the cap' ( unlike when converting to Sony E or Fuji X for which one can mount the lens on top of the cap ) I had used a hard rubber ring that I had lying around to fix the lens in the recessed position. The conversion is 'somewhat' documented here, I hope this helps: http://ricohforum.com/phpbb/viewtopic.php?f=63&t=10202&start=20
btw. in the same Ricohforum there is also a thread showing my conversion of Pen-F lens to Leica M, the first one I did, a 1.8/38. First seen my failed attempt to mount a Leica Bajonett on top of the lens mount, later I successfully converted by removing the original mount and replacing it with a Leica M mount ( a 'cheap' LTM>Leica M adapter ): http://ricohforum.com/viewtopic.php?f=63&t=8301&start=20
cheers, andreas

You are quite talented in doing such complex conversions. Thanks for the links.

Understood.
I agree with you on the high quality of Zeiss QBM lenses. Amedeo offered once a conversion service for the 50 lens, but he did not continue it. I asked him more than once about it.

thank's and welcome. I love doing such things 🙂 As you can see there had been wrong holes drilled in the adapter first, second holes were spot on. My later Pen-F conversions look better, though different Pen-F lenses each needed an individual solution to make it stop down, e.g. for that the machined 'cover' for the 1.5/60 needed to be deeper and have a 'step'

I think the reason we don't discuss it nearly as much anymore is because Brian Sweeny isn't on the forum. It was his techincal forum threads that really kept the discussion on hacked lenses alive.
I don't have a Leica digital anymore but I do have a Nikon D3 that is itself, a bit hacked to create the viewfinder I want. When I get another Nikon D2H, I'll remove the AA filter and have a full-time IR camera. It's that ability to fine tune the lens registration with instant results that a digital camera affords. I only have one hacked lens right now, a 90 year old Kodak meniscus lens in a ball bearing shutter stuck onto the end of a Minolta push-pull zoom (with no elements,) re-flanged to Nikon F. It provides some pretty awesome results.
I'm thinking about mating the optics of a pair of 10" and 12" Wollensak large format lenses to focusing barrels for my D3.

I have the opportunity to buy a professionaly converted 21mm 2.8 Biogon from G to M mount.
Is this particular G mount lens really that good?
What do you think, it seems to be smaller than its ZM counterpart and Imo "preetier" 🙂

I have hacked a lot of large-format lenses to my three Plaubel Makiflexes.
I have a workshop in my garage, with mini drill press, grinder, band saw, and
scroll saw. Also a lot of hand tools are used. And specialized camera repair tools.
I enjoy the metalworking, and I end up with a lot of unique things.

I have two Contax G lenses that I had converted to M mount, which I really like. I have a 90/2.8 R lens that is currently wearing a Leotax Nikon mount. And I know that this is not what you are asking, but I have many adapters that allow use of non-OEM lenses with Olympus EP-2, Sony Alpha 5, Fuji X-1 Pro etc. It is all for fun.

I have the G 28-45-90 trio, but I have heard only praises about the G 21. I have also the 45/2 in M mount.
The G 45/2 Planar may be a touch "better" than the ZM 50. I bet, both lenses are great lenses.
What is the cost of your 21?

My last 'hacked' lens is an Agfa Anastigmat grafted into a filter case, then held into a Bronica S lens mount.
Here's a picture of it: https://farm9.staticflickr.com/8397/8614296701_db0382db07_z.jpg
I am waiting for the day when 3D printing can produce quality *metal* lens adapters. I'd love to use my Mamiya CS 21mm 1:2.8 on a full-frame digital camera.

in hong kong in the local camera circle there are quite a bit of imaginative oldtimers and camera hackers here to change old point and shoots or weird lens into your A7 or leica m mount. i seen a contax t2 38mm lens adapted to m mount as well.
i been thinking of taking a stepless aperture from a old jupiter 8 or some other broken old FSU lens to construct a working aperture with some point and shoot film cameras to adapt into a m mount (screw mount adapter).
i was thinking of adapting the yashica T with the zeiss 35mm 3.5 lens, and also a broken down 28mm 2.8 from the Gr1s as well.
currently i have two MS optical lens for the m mount; a 28mm 3.5 fujifilm lens from the super mini/ tiara, and a 40mm 2.4 summarit from the minilux.
for other mounts, i put a cheap OM to Nikon F mount on a old zuiko 50mm f1.4 with great results. It really handles great on my FM2n.

raid: it's about 700 euros with finder, uv filter and contax case. The conversion seems to have been done really good.

I've always tried to use lenses intended for use with the specific camera. The only hacked lens (assuming this counts) is a 24mm/f2.8 Nikkor AF on the front of a Hasselblad XPan (via an adapter made to mount Nikon lenses on XPans). The intention had been to avoid the need to buy the 30mm for the Hasselblad.
It worked - sort of - but it produced an image with rounded sides that didn't quite fill the whole negative. Apparently, the 35mm PC lens works much better as it has a bigger image circle. Anyway, after a while, I ended up buying the 30mm......

cheap " hack" lenses
cheap " hack" lenses
One of the cheapest lenses to hack, & easiest, are the
Paxette lenses.
You can fit them to just about anything.
M39 adapter & an extension tube of the correct length. 14mm or there abouts.
Large flange focal distance because of the leaf shutter behind the lens.
I have a couple of Xenars and a Steinheil Cassarit both 50 2.8.
Tho my best results came with a 90mm Roeschlein Kreuznach Pointar.
