DIY tilting close up lens

A couple years ago I began seeing tilting lens adapters on ebay and thought it was an excellent idea for close up work and thought, someday I should make one using an enlarging lens. This would of course be a manual focus manual diaphram system. The tilting function can give extended DOF in certain planes using the Scheimflug principal as used by 4X5 view cameras.

Then, about a year ago Canon came out with 3 different "tilt/shift macro lenses" for about $2K each ! The 90mm is f2.8, tilts 10 degrees and goes to 1:2 mag. So this served as additional inspiration to do a DIY version.

I use a Sony A77II which is basically a mirrorless camera with a prism box. The EVF works good with manual diaphram lenses so that would be my base body. My goal would be to do small tabletop product and floral type subjects - no bugs or 1:1 !

I started with a helicoid focusing extension tube in the 12-17mm range in M42 mount $20 - and used a m42 to Sony A mount adapter on ebay - $10.

I then got a M42 to M4/3 tilting adapter (this would go on the front of the focusing adapter) - you cannot get a M42-M42 tilting adapter - that is what I wanted - so I planned on modifying the M4/3 to make it M42 screw- $24 on ebay. I would be using a dremel tool and a 39-42mm screw adapter so I could make it screw into the front of the helicoid. This tilting adapter can rotate 360 degrees so the tilt can be adjusted in any direction.

For lenses, I started out with an expensive ( $80) 60mm f4 enlarging Rodagon ( 6 element) and found out that with using the tilt adapter I could only get 1:1.3 to 1:1.7 - which was too much magnification ( for me). So I decided to try an in-expensive ($20) 90mm lens ( a 90mm f4.5 enlarging Raptar 4 element) - which gives me 1:9 to 1:4.2 which is more like what I was looking for. I can use a normal extension tube for greater magnification than this if needed. A 75mm enlarging lens would give mags somewhere in between the above ranges and would probably work for most people. I converted both enlarging lenses to M42 screw so I can interchange them on the front of the tilt adapter OR the focus tube. I may go ahead and get a 75mm lens also. You may notice the small profile of the 90mm enlarging lens - this helps to allow more light to the subject in really close work as opposed to using a large purpose designed full fledged "macro" lens.

So, below is what it looks like .... with some example images.

I understand to some degree, tilt-shift for buildings. I am totally lost as to it's advantage for macro purposes. Perhaps you can explain it to me. I don't even know what I'm seeing in the photos. My stupid question would be....why not just tilt the camera? I hope you don't mind educating a dummy!!

I bought a Nikon to Sony adapter with tilt and added my 35 shift Nikkor to the front , hence 35mm tilt , shift on my Sony 6500.

- Yes, working with the Sony E-mount is a much better situation !

IMO, maybe the ultimate set up would be the 55mm micro Nikkor on a tilting Nikon to Sony-E adapter !

Without Math and Science the world is an illusion. I appreciate the Wiki reference as well as the subject of Tilt Lens modification. imagemeister, Great example photos, indeed.

I spent a lot of time searching for a Minolta AF Tilt Adapter... I have a Sony A65 which is truly an Minolta ALPHA... why Sony bastardized the word Alpha stolen for use in E Mount cameras like the A7... i do not excuse. My friend in england bought a A7 now messed up having to use an adapter for low cost Minolta Maxxium lenses.

Many Tilt adapter but non did I find for classic AF mounts. Did I miss one in the under $50 range?? I have several M42 lenses as well as Nikon [8088] and a Pentax film SLR .... Help me adapt !

Read some material and watch some videos on the Scheimpflug principle and how it modifies the zone of focus.

https://www.waldonell.com/photos/photography-articles/focusing-normal-and-tilt-swing-lenses

A flower closeup is an excellent use of a tilt lens - with the flower rarely vertical, being able to tilt the lens downward to extend zone of sharp focus without necessarily needing to use a tiny aperture will provide more flexibility and images that are relatively free of softness from diffraction.

Nice results. And very accessible - the costs are not high at all.

See the Wiki link given by RWR - it is basicly fairly simple - but actually describing it accurately can get very technical !

I looked also and cannot find a M42- to Minolta AF TILT adapter - but there are of course straight m-42-to Minolta AF adapters CHEAP - and plenty of M42-Sony E-mount tilts !
