I was imagining if ,fujifilm itself or any third parties ,make a auto focusing speedbooster to use fujifilm gfx lenses on fujifilm x series camera's !! . i might sound stupid , but actually it has great benefits in many area's . people who own x series and gfx series ,don't have to buy different lenses . also the camera industry is slowly shifting to medium format from full frame , so we will start seeing speedbooster for gfx lenses to different fullframe mount's of other manufacturer cameras too . so what do you think about this ? ,let's us all share our opinion's here ! about this , so maybe this might lead to a speedbooster ,like we said ! ,from fujifilm or third parties !! ,since many are using gfx camera's these day's ,who also has a x series body with them . so share your opinion's about this here , have a nice day !
