After using revamped HD 35/2 for over a year, and using older version for quite some time before upgrade, I can say that this "only" coating update gave that lens a new life for my usage(I'm pretty sure that glass formula was changed to fit new coatings, not only coating itself). Also exterior design fits better with a lot better quality plastics and rubber focusing ring that does not slip.
Reworked FA77 HD version will find a new home in my camera bag I think
I wish that there could be room for updated FA50/1.4...
