Minolta/Konica-Minolta/Sony A Lens To Leica M Body (Techart Pro LM-EA7) Adapter

Description

In 1985, Minolta Became The First Company To Produce A Body-Driven Autofocus 35Mm Slr -- The Maxxum 7000 -- And With It, The New A (Also Called Alpha Or Af, Replacing The Incompatible Manual-Focus Sr/Mc/Md) Mount Became The Camera System To Have. Unfortunately, Lawsuits Soon Followed: Exxon Sued Over The Typography Of "Xx" In Maxxum And Honeywell (Pentax) Sued Claiming The Autofocus Technology Infringed On Their Patents. It'S A Long Story, But That Began A Slow Fade; Minolta Became Konica Minolta In 2003, Finally Giving Their Camera Business To Sony In 2006. Although A Mount Is Now Second To E For Sony, By My Counting, More Autofocus Lenses Have Been Produced In A Than Any Other Mount, So There Are Plenty Of Reasons To Want To Adapt A-Mount Lenses... And There Are Various Adapters Available -- Including The La-Ea1/2/3/4 From Sony Itself. Ok, So Why 3D Print This One? Because We Can Seems Like A Decent Answer -- This Is An Easy Print In 2 Pieces, The Adapter Itself And A Little Locking Pin. Certainly, This Adapter Fits Nicely On A Techart Pro Lm-Ea7 Autofocus Adapter And Uses Only About 12G Of The 700G Drive Limit For The Lm-Ea7. It'S Great For Manual A-Mount Lenses. The Catch Is That It Doesn'T Yet Incorporate An Aperture Control For Autofocus Lenses... Which Are The Vast Majority Of A-Mount Lenses. Hopefully, I'Ll Find A Good Way To Implement That Soon... But The La-Ea4 Adapter Already Implements Aperture Control And Native Autofocus Using Those Lenses On Sony E Bodies, And I Own An La-Ea4 As Well As An Lm-Ea7. The Last Two Photos Were Taken Using The Lm-Ea7 On A Sony A7Ii, Autofocusing A Manual-Focus Samyang (Opteka) 85Mm F/1.4, Both Shot Wide Open. In Fact, It'S The Only Manual A-Mount Lens I Own. Exceptionally Smooth Bokeh From That Lens, But That Super Smooth Transition To Out-Of-Focus Makes It Hard To Focus Manually. By Itself, It Also Has A Rather Long Minimum Focus Distance, Which Isn'T A Problem Combining Manual Focus With Autofocus Tweaking By The Lm-Ea7. I Think This Lens By Itself Is Enough To Justify Making This Adapter, Although There Are Some Other Great Manual Lenses In A Mount From Companies Including Samyang And Zeiss.
