Good work, sebboh.
I'm semi interested in doing a G28 remount, but with the $400+ going rate for a G28 lens, plus $100 for donor lenses and parts, I'm not sure of the cost/benefit considering I have the ZM25, and the G28 is at least if not more symmetrical with the need of a corner fix. I do say that the G28 has a better MTF than the ZM28, though.
I have been waiting for over 6 months for a Hawk G45/M mount conversion that I was going to deconstruct for possible conversion ideas, but I could have easily bought a ZM50 for equal or less money.
The ltm-M adapters may not have the diameter you need for screwing to the Minolta lens body.
Don't you have a Minolta 28/2.0? and how does it compare to the G28 on the N7?
the cost issue has changed a bit since i bought my g45 for $200, but i think even at current contax g prices the g28 and g45 conversions will still be around $300 cheaper than the cost of the zm version. i do like the g mtfs better for both lenses as well, though the zm lenses probably have better coatings and have more aperture blades. the rokkor 55/1.7 is basically a $25 dollar lens (though a very nice one).
the ltm-m adapters that have an uninterrupted outer diameter (instead of the ones where the outer diameter is shorter for part of the circumference) could be screwed into the tapped holes on the minolta lens body. i'm not planning on actually doing that though. my plan was to attach the spacer to the lens body and put tapped holes in the spacer with which to attach the adapter.
the g28 and rokkor 28/2 are very different lenses look wise and the rokkor is nearly three times as long with the adapter making the camera/lens combo lose it's compactness. the contax is definitely higher contrast with lower CA and probably also sharper (but i haven't done any comparisons). the g28 does have a little smearing on the NEX-7 in the corners (but looks pretty good on the 16mp sensors).
