Re: Wide Angle Lens - opinions please

My default MF lens for astro is the Rokinon/Samyang 12f2.  Note that I stop it down to f2.8.

My default AF lens for astro is the 14 f2.8. I shoot it at f2.8. Note that I use MF when doing astro with this lens.

You can use the 23f2 for astro, but you are going to have to stop it down to at least f2.8, potentially f4.  You will have noisier pictures at f4 (higher ISO, or boosted exposure), and you will need to stack a number of shots for decent results.  Also, your Max shutter speed if you want to avoid trailing is going to be around 10 seconds.

Everything I have read is the 16 f1.4 has significant coma wide open, and you need to stop it down as well.  Whether that needs to be f 2 or f2.8, others would have to say. I've read a number of discussions expressing disappointment in it as an astro lens, so I stayed away. It's reputation outside of astro is tops.

Of all the distortions and lens "imperfections", I find coma to be the most annoying when stars have weird shapes with tails.

The conventional "wisdom" is that the Rokinon 12 is the "best" astro lens for Fuji. It's coma is well managed. I enjoy shooting it at other times, too.

If you want AF though, I'd go with the 14, a sweet lens.
