I can't give you the body at the moment, as I am thinking of switching camps at the moment That is why I want to consider an adaptor
Dare not ask at the official forums, those people will simply tell you :
1) Don't switch systems as you will loose out.
2) Since you already switch, why do you want to keep the old lens for, sell all and use the cam body manufacturer's lens. (They also sort of dissuade me from using 3rd party lens like Tokina, Sigma and Tamron)
For my answer to
1) I have other cameras that can still utilize the lenses, so not much loss to me at all.
2) Seems like the main alternative for adaptors (discounting EVIL/M4/3 systems) are for Nikon lenses. Which after looking around at clubsnap, accidentally got poisoned by them, the primes are good and reasonably priced. If the prime of the body manufacturer is deficient or over priced, I just might go with them.
Fortunately can tap your experience. But the adaptors are also not that expensive ($20 unit until it makes me worried if it can work well ) , if I can or need I will try to get a better one.
