Herb, you need a Hawk\'s helicoid adapter for your M lenses! That\'ll get that mfd down to around .3m.
I hope Pentax doesn\'t make a Samsung blunder and make the registration too long for M lenses. A Pentax 135 mirrorless sounds great!
Also, while the 5N is better than most in the corners with M lenses, Sony really needs to ax the AA filter, so we get GXR-like corners. I\'m hoping MaxMax will do it to my 5N, but they haven\'t responded to me.
Thanks for the Hawk\'s info Douglas.
I am not confident that removing the AA filter will solve all issues. There is also a UV / Infrared filter / protective glass. The sharpness available with the GXR is partly related to the AA filter, but the corner behaviour has more to do with the microlenses and the glass layers on top of the sensor. These layers must be as thin as possible for some lens designs to produce sharp corners. I am not a sensor specialist but this is what I understand of it.
