Hello.
Say you have some manual focus lens and DSLR and you have been offered opportunity to convert your lens to autofocus lens. (process is reversible and no damage/modification is made to lens). How much you'd agree to pay for this? $20, $50, $100, $200 or? _________________ I have nothing to compensate with lens |

Hmm, no.
I did the opposite, Contax G45 mounted in Rokkor MC 55/1.7 body, and is M mount.
So, I might be biased.
The only way I'd go for another AF camera is if someone made an all out pro spec mirrorless, NEX-7 layout, Canon 1D series build, full water proof to 10m, A camera to do it all. _________________ A Manual Focus Junky...

Pentax 1.7x AF adapter is worth around $300 these days. If something similar was available for Canon or Nikon I am sure it would sell in $500 range. |

I will say no, of course, I can't afford to buy an AF lens, lol . However, I love anything in vintage style, and the vintage lenses are really interesting me. |

There are times.
Often with a moving animal, or changing light, or a child changing expressions, or a person in conversation moving, its hard to keep these situations in focus, or focus fast enough.
But it has to be very accurate autofocus. Most such lenses I have tried seem to consistently slightly off.
That's not a good substitute for MF, which can usually (except for cases like I mentioned) be exactly on. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Say AF accuracy will be the same as your camera AF system offers. Regarding the lens interchangeability, it would be possible at some extent, as all lens have different construction, various location of focusing ring and so on. _________________ I have nothing to compensate with lens |
