Canon-EF to Nikon-F conversion ring (EF-lens to F-camera)

Canon-EF to Nikon-F conversion ring (EF-lens to F-camera)

Description

This Is A Conversion You Won'T Find Purchasbly On The Market Due To Several Reasons: 1. You Won'T Be Able To Control The Aperture Of The Ef-Lens Neither With Your Nikon-Camera Nor Manually On The Fly.* 2. The Flange Focal Distance Of The Nikon F-Mount Won'T Allow You To Focus To Infinity Even If The Ef-Lens Is Fitted Directly To The Camera. An Additional Conversion Ring Will Make It Even Worse. So, Why Designing And Printing It Anyway? I Had To Equip A High-Speed Camera (Guess The Mount ;) ) With A Fast Tele-Macro-Lens For An Experimental Setup Due To Several Reasons But Only Had A Suitable (For Our Wallet) Lens With An Ef-Mount. Since I Wanted To Use The Optical Setup At A Small Distance, The Missing Possibility To Focus To Infinity Didn'T Concern Me. And Since There Is A 3D-Printer Accessible, There Would Be Different Options To Retro-Fit An (Fixed) Aperture. Disclaimer Use The Conversion Ring Wisely And On Your Own Risk. I Won'T Be Responsible For Any Damage On Your Equipment. /Disclaimer The F-Mount- Side Comes With A Pit That Engages In The Locking Mechanism Of The Camera. Lens-Wise There Is A Preliminary Hole To Drill And Tap A Thread For A M2.5 Stud Screw That Can Lock The Ef-Lens. Possible Design Improvements (If Time Is Available): -Narrow The F-Wise Locking Pit -Add Markings Where The Parts Have To Be Attached I Used The Conversion Ring Made Out Of Pla On An Analogue Nikon Cam And On Our High-Speed Cam And Tested Ef-Lenses, An Ef-S-Lens And Several Other Parts With An Ef-Moun (E.G. Macro Tubes). *Except For Some Tricks Like Dismounting The Dimmend Ef-Lens From A Switched-On Canon-Cam Or Additional (3D-Printed) Aparture Equipment
