Looked through the forums and found a FF lens is coming out this year (it will be available in Canon, Nikon,
Pentax K, Sony A and E mount). It is LAOWA Smooth Transition Focus (STF) 105mm F2.0 (T3.2) Manual Focus. A direct comparison of this lens is Minolta/Sony 135mm f2.8 [T4.50] STF.
LAOWA belongs to a Chinese startup, which makes 60mm F2.8 2:1 macro and 15mm F4 1:1 macro (which are also available in Pentax K). I learned that a
12mm F2.8 FF lens (in Pentax K again) will also be released soon!!!
STF 105mm F2.0 ( U.S retail price is estimated to be around $600 - $700):
