Because I have Samyang 14mm for landscape and asto shooting and I like it except next thing: I can't put round filters and take off lens hood, strange mustache distortion.
With Irix 15mm I have opportunity to use filters and rear gel filters, acceptable distortion. Also I like focus ring lock function, infinity click function. But also read that some lenses have bad optical quality with discentered effect. And at /2.8 aperture sharpness in the corner quite soft (Samyang has perfect sharpness all over the frame at /2.8).
So tell me please change Samyang on Irix or not? Thanks!
I have the Samyang 14 and I have friends I shoot with who have the Irix 15.
Personally I think the main difference (if you already have a good copy of the 14/2.8) is the distortion and the other is the external build quality (plus to the Irix).
With the distortion, its a double edged sword imo.
I find that images that have a subject does have a bit more pop to them over a distortion corrected image.
Futhermore, the LR profile does a decent job in most cases and at most that 14mm becomes 15mm after the crop.
For me, I have not changed to an Irix since I feel that the difference is not that big a deal for my needs.
