I am kinda satisfied with anything. Sure, a 1DX would be nice, but that won't be happening anytime soon.
I would really love an affordable ultra wide prime or zoom instead of my manual Samyang, which I am satisfied with by the way, but just to scratch off that manual focussing. Sadly there is no real alternative qualitywise other than the Canon 14mm L II prime itself which is way too expensive. Tamron 14mm, Sigma 12-24mm, Sigma 14mm all are while being affordable far away from reaching the Samyang's image quality.
