Hängde inte med. Vilka tekniska hinder skriver du om? Jag diskuterade deras objektivfattning och med det helheten. Inte bara omkrets och tjocklek. Nedan är några utdrag från de artiklar jag läst om varför det inte finns bra adaptrar för F-mount. Nåt problem är det ju.
“Talked to Sigma tech rep: Sigma will not be making a NIKON version of the mc-11 ever. The reason for this is that there are differrences in how the Nikon lenses work that would be problematic, so Sigma decided to only make Sigma and Canon versions because they are easier.”

"What Took So Long?
In short, Nikon lenses are enormously complicated to adapt. Unlike Canon which switched to EF-mount when they introduced AF, Nikon remained committed to F-mount. But that commitment came at a price. Nikon AF lenses have more variations than wardrobe changes at a Lady Gaga concert."

"To hear Fotodiox explain it, the reason this adapter took so long to make is that Nikon AF-I and AF-S lenses are not fully electronic—the aperture is still mechanical.
“We had to create ‘Fusion Drive,'” says Bohus in the video. “That’s the technology built into the adapter itself that lets the Sony camera control the Nikon lens’ mechanical aperture. This is the breakthrough that makes the Nikon to Sony Fusion adapter possible.”
