  • Go between mount: EF for vintage SLR and longer register distance lenses. To fit (preferably with chips added) on an intelligent EF to Sony FE mount. Should make a change to another mirrorless ...
  • Replied in Petri Duck Tale
    Three ducklings counted 25% crop of the above image.  Quite sharp in the center with a nice fall off backwards. 8 aperture blades may be one of the reasons for that.   Odd as I bought the Petri 7 ...
  • Metabones EF to M4/3 Speed Booster most likely will transfer the latest version EMF AF confirmation chip programmed data. Like the Metabones IV EF to NEX adapter (latest firmware) does to my Sony ...
  • Replied in Stereokeh
    A 3D printed hood like shown here could be enough. This one clamps in some grooves of the other 3D part. He might need some extra blinds in between the 3 lenses but still possible. Probably ...
  • C-mount lens like the Schneider Kreuznach Xenon 50mm 2.0 that I liked very much for portraits when I still used an M4/3. https://www.dpreview.com/forums/post/59024861 C-mount extension tubes exist ...
  • Replied in Stereokeh
    Well, someone is already more ahead than I am and sells them for wigglegrams. He could have improved it with some blinds at the front though. ...
  • Though with another goal in mind I also printed a 3D twin lens adaptation for a Sony FF mirrorless about nine months ago. It is correct that there is little depth at the rear to separate the rays...

  • This dates back to the time before adapting vintage lenses on digital bodies became possible. There were plenty of these lenses available and the people that used Aero Ektars on Speed Graphics ...
  • No, register distances difference is about 10mm negative and the camera M-mount too narrow for improvising. https://en.wikipedia.org/wiki/Flange_focal_distance#:~:text=For%20an%20interchangeable%20 ...
  • Interesting. Images are nice too. There is a 3D printed adapter to a Graflex 3x4 SLR camera for that lens: https://20thcenturycamera.com/products/dallmeyer-pentac-8-f2-9-lens-mount-front-standard-f ...
  • First check which mount your lens has: https://vintagelens.nl/2018/02/19/slr-lens-mount-identification-guide-richard-oleson/ Met vriendelijke groet, Ernst No photographer's gear list is complete ...
  • My Tokina AT-X 90mm 2.5 with PK mount has an PK<>EF adapter. It turned the scales about 15 degr, more than I liked. Took the lens apart and removed the levers that are in the way and with the lens ...
  • My way of thinking when I opted for the Canon  EF in between mount adaptation to a Sony FE body. If I keep the EF<>FE (intelligent) adapter on the body and have EF mounts on SLR lenses I could ...
  • And at the page you refer to is an image of the mount rear that says: Made by Rollei Singapore and at the side of the lens: Made in Japan. I was actually not looking for that but to see what size ...
  • At another list I see both described as 7/5, lens-db.com. However checking the lens diagrams I doubt the first two elements can be kitted. http://www.klassik-cameras.de/Rollei_QBM_Schneider_dt.html ...
  • It is however not based on the optical design as used in the Mamiya Sekor ES SX. Both 7 elements 5 groups designs but different. If I can trust the lens diagrams on the web. http://www.artaphot.ch/ ...
  • You have done a nice job in adapting it!  Last time I saw an Olympus Ace including the 3 lenses it went for 800 Euro.  My curiosity did not go that far. Met vriendelijke groet, Ernst No ...
  • Nice. Do you also have the 35mm?  Intrigued by that one as a Heliar design is not something you would expect to be used for a wide angle. Sure it is a slow 35mm but nevertheless. Wonder how it ...
  • Tessar, Heliar, Plasmat, hybrid Plasmat/Planar, other Planar derivatives, more complex less definable designs without and with floating element(s) are roughly the stages in macro lens designs over ...
  • To make my custom 3D printed hoods I test an existing one on a copy table with the lens set wide open and at infinity. Table board is evenly lit. Adding filter rings with the glass removed shows ...
