hi, got a XF50-140 and after a couple of days i noticed that the lens loses the connection to my x-t1 body during shooting. the x-mount bayonet got some rotating lash but this seems to be normal, after some search at google. but at a specific position during shooting / rotation the lens loses the connection. it's kind of a short blackout. my xf23 works great, now issues and the x-mount bayonet is tighter then on the xf50-140. strange...
so i get in touch with the local fuji support and send it warranty repair. after 3 weeks i got it back ... they replaced the board /mainboard of my x-t1, the lens is fine they said. but i noticed one week ago the same issue. and yes, i will send it again to fuji support to fix it. i asked some of my friends (nikon, canon shooters) with 70-280 lenses and they never noticed this kind of issue.
my question is: do others recognized this kind of issue? what it may be? it still believe that the x-mount bayonet of the xf50-140 is the reason. would be thankful for any hints.
best regards
simon
