I can't decide if I want to build up on Fe mount lenses or not. I feel that Canon ef lenses will stand the test of time but unsure if Fe will. I'm not sure if that's just because I was recently stung with fuji though. I'm sort of thinking there will always be Canon bodies to choose from but will Sony be in it for the long haul?
Perhaps they will keep leading the way I don't know but its just a slight niggle in the back of my mind
That's been my concern all along and why I have so far not purchased an FE lens.
I have the same concern as you guys... Most of my photography doesn't need AF anyway so I think I will stick with Canon glass, and the times I need AF I will always keep a Canon body.
