je vais voir ce que je peux faire ear....y2k quelle version du 200mm tu recherches, car il y en a 3 et non 2 :
The three possible versions of the 200mm/2.8 are:
o The first Apo version: slow auto focus, no AF stop button
o The upgraded Apo version: fast auto focus, no AF stop button.
o The second G ? Series version: fast auto focus, AF stop button
and ?High Speed AF Apo 200mm' decal.
The difference between the original version and the G version according to Minolta:
The G versions have a different IC rom and gear that speed up the AF with 33%. It also has one focus hold button located on the barrel. There are some physical differences between the versions (e.g. the focus hold buttons). Glass is the same. "G" is an attempt at marketing. It is possible to have the original version upgraded (this has been done since the G version was introduced in 1988). The lens will get the new IC and gear but not the focus hold buttons. Minolta may not have the parts to do this anymore. Also, I understand that parts for the original are starting to get scarce and service for it may not be possible in the near future. The price for the upgrade is about $300.
