I also used to own the 14, and I've now owned the Rokinon (aka Samyang) 12 f2 for about 3 years. Thoughts, should they be of any use:
XF 14 f2.8: Optically you'll never complain. But then it's an XF lens, so you knew that. The AF speed is pretty good from what I recall, but hell, for landscape / urbex, who cares? The focal length is indeed wide, but not wide enough to get a true 90 degree field of view, which matters (to me) when shooting interiors... standing in a corner, you can't QUITE get the whole room in. But it's wide enough to distort faces badly in the corners or when they're super close, so when shooting around people you have to be careful not to get heads / faces outside the center area and step back a little. Wide lenses do strange things to shots (which can be used for good, or evil), and I always felt like this lens wasn't quiiiite wide enough to REALLY do those things when I wanted to, and I just never clicked with it somehow. It was my only wide lens for over a year (next widest was the 35) so I had plenty of chances, and just couldn't bond with it.
Samples I took with it...

f7.1. Zoom in on the scarf to the left. Crisp as hell.

Rokinon 12 f2:
This lens benefits (fairly or unfairly – you decide) from Underdog status. It’s a little over $300 new around here, usually $200 used in good shape. So your expectations start off pretty low, which is an easy bar to clear… When you spend $25 on an old Minolta 50mm f1.7 at the flea market and it’s surprisingly crisp at f2.8, you say “cool! Money well spent.” But a month or two later, honestly, you don’t think about what you paid for a lens. Once the reverse sticker shock euphoria wore off for me, I realized there’s not really a
catch with this lens. “Yeah but it’s manual focus” is supposed to be the "gotcha," but in practice, I never miss it. At f2 it’s a little soft – and I mean a LITTLE, not “like film lenses from the 70s,” just a
little soft, and with a good stop or two falloff at the corners. If you’re shooting in daylight, though, you just peg it at f4 or 5.6, focus a little back from infinity (the focal distances are marked on the barrel, but you’ll quickly do it just by feel), and everything is crisp, everywhere. Things I came to love about it:
- True 90 degree field of view means getting the whole room in, or the entire waterfall you’re standing right in front of.
- Smallish, lightish, and yet f2 on tap = it sneaks into your bag for indoor / evening events.
- Nicely damped focus and aperture rings. It moves a tiny bit in the body mount, but it doesn’t affect pictures.
- Perfect combination of crisp details and a few charming flaws, like the way it flares when pointed right at the sun. People spend hours trying to get that in post, and if you don’t want it … don’t aim at the sun without a hood on!
- Not much saggital coma to speak of + f2 = star shots! The XF16 is soooo good in every other regard, but is prone to coma, which was a no-go for me.
- 12mm is wide enough to do neat stuff with. Tree branches, clouds, foreground elements in landscape photos, things that CAN be allowed to get all bendy start to really draw interest into the shot, without going fisheye. Leading lines are your friend with this lens.
- Bokeh! No seriously, it focuses really close, and the bokeh is smoother than a baby’s butt.
In summary, it’s been a wonderful companion, and I’ve gotten so much good work done with it. I thought it would a specialty toy, but it’s a workhorse.
