Why? Images from the Samyang are much better than from the Canon 14L which costs 4 times as much.
I own the Samyang 14 and in my opinion I would trade it for a Canon 17 TSE in an instant.
For an inexpensive lens the Samyang is a great buy, but it does have its limitations:
The focus calibration is off a mile, the infinity focus point is at 1m on the lens barrel.
The Distortion is pretty severe. I use PT lens but it is a necessary post process step with this lens.
Mine is not sharp at f2.8 but is fine from f4 onwards, while the 17 TSE is sharp wide open at f4.
the Samyang will vignette pretty strongly at f2.8 anyway, so I never use it at an aperture wider than f4.
Finally the 17 TSE has lens movements, which I enjoy being creative with. By shifting the 17 TSE one can get a much wider aov than a 14mm lens.
