Question Fuji X Mount lense for astro

Hi all,

Any recommendations on a wide angle X Mount lens? Any hands on experience? I see there is a 14mm f/2.8 but report says it's got soft corners.

I have the 27mm f/2.8 pancake which is perfect optically but not wide enough for astro wide field.

Regards,
Roger.

Fuji 14mm F2.8 XF is an awesome lens. A very tiny part of a corner can be a bit off but otherwise perfect wide open. A rarely almost perfect lens.

The Fuji 18-55 F2.8 is also a very good lens wide open at 18mm;

I'd like a 12mm rokinon for my fuji x cameras.

What I do have is the fuji 18mm f2 prime I use for MW galaxy.

Not that wide, but does a nice job, a keeper.

I have the 12mm Samyang/Rokinon...it's inexpensive and wide, but the corners are filled with shapes. I don't recall if this was at f/2.0 or f/2.8.

Ooo... they are pretty crosses aren't they I think I'll give that one a miss.

Any chances of a 100% JPG/RAW or corner crop ? Happy to dropbox or PM or whatever.

Thanks Greg,

The top left particularly of the 14mm F2.8 XF looks to have some crosses and softness. Any chance of a full size image?

The panorama is a bit hard to tell the quality of the lens, because ... well, you know how panorama's stretch things ... would be great to see an individual frame

No worries Roger, here are a couple, a straight jpeg from a month ago and the second is a RAF I banged out quickly in LR the other night when time was to spare. I'm yet get the time to really process them and establish a preset so please no-one judge them as they are thanks!
It gives an idea of coma, not shocking. .

Both are the 18mm at f2, around iso 1600 or 2000, 30 secs via remote release. Not wide, but a nice scale for detail I think. Then, there is the crop and stitching option anyway. That would be the go.

Send us a PM with email for a RAF if you like.

Hi Roger
The Zeiss 12mm is very good at F2.8 and excellent at F3.5 and a much better deal these days than when I bought mine
