To the OP: the purpose of photography is to enjoy yourself taking pictures. It is not to purify the soul through suffering, or to accumulate 'dream outfits'. If you don't enjoy the way things are going, do something else (including changing jobs if you're a professional). Or at least try doing things a different way.
Back to crsantin. I'm 62; sold my last car with a slushbox (Scimitar GTE) years ago; and vastly prefer my Ms (film and digital) to any autofocus I've ever used. It's ALL personal.
