[QUOTE="ejronin, post: 626034, member: 43743"] So I bought an Olympus 28mm f/2.8 - excellent condition. Really like the output of these lenses, and after research discovered the 28mm 2.8 is a lens many struggle to adapt and mount. Leitax however, [I]does[/I] make an adapter for this lens and can affix the Dandelion chip on it (I'm not a fan of it). The Leitax site instructs the use of their [URL="http://www.leitax.com/OlympusOM-lens-for-Nikon-cameras.html"]"special" adapter when purchasing for the 28/2.8[/URL], and about 4 other pieces of OM glass, specifically. I ordered one. It came yesterday. I converted the lens from OM to F mount. It wasn't mounting correctly. I was sad :( (read: angry) Sparing the story of how I arrived at a solution, here it is: [B][COLOR=#ff0000]First, a bit of warning - the solution is somewhat destructive and you'll need to be very careful not to dirty the inside of the lens. [/COLOR][/B][COLOR=#0000ff][I]I didn't dirty the inside of mine, but that doesn't mean it's impossible or even unlikely; I was just fortunate. This conversion will leave some openings near the rear element and look 'naked' compared to the original lens.[/I][/COLOR] If you look at Nikkor Lenses, the lens mount screws on the lens are flat-head and inset. On the Olympus 28mm f/2.8, the screws are pan-head and recessed for a fit to an Olympus body. If you're using the original screws, you'll need to file them down to be [I][U]flush[/U][/I] on the "special" Olympus mount. If you don't, the screws will not only scratch the ever-living bejesus out of the mounting ring on the body, but it will not turn more than about 1/4". Pictured: Unfiled screw. They don't stick up much, but it doesn't take much to impede coupling. [ATTACH=CONFIG]258397._xfImport[/ATTACH] [ATTACH=CONFIG]258404._xfImport[/ATTACH] I used a [URL="https://www.amazon.com/Tamiya-74066-Diamond-Photo-Etched/dp/B000E7ONQQ"]Tamiya #400 diamond file[/URL], used to file down metal 'detail parts' when cut from a metal sprue. At the time of this writing, they're about $10. Once the screws were flush with the mount, the lens mounts just fine and there are no issues with coupling or decoupling.
