24mm f/1.4 -vs- 14mm f2.8

With regards to shooting the Milky Way and aurora borealis.  Would it be better to have a 24mm f1.4 or a 14mm f2.8?

It'd be better to have both... but if I had to choose just 1 I would stick with my 14mm. The 24mm just isn't wide enough for most shots. I use it for panoramas but for single shots I prefer the 14mm.

They are both great lenses, and I use both a lot. The 24mm is the better lens as far as IQ and sharpness, but the FoV is much smaller than with the 14mm. If you just want the Milky Way the 24mm might do, but if you need a wider view I would go with the 14mm. There are ACR/Lightroom lens profiles available for the 14mm that correct the mustache distortion, so need to worry about that.

For best view of Milky Way in a single shot: Samyang 14mm f/2.8. Note also that you can expose for 35 sec on full frame and still get only slightly oval stars.

One can composite shots taken with narrower FOV lenses, but things get complicated because the acceptable exposure time is less for 24mm (say), so you don't get as big a benefit from the faster lens as you would think. Compositing shots is more complicated for beginners, so I heartily recommend the 14mm f/2.8 to get as much fun in as early as possible.

There are other options for APS-C - Samyang 10mm users, speak up!

Thank You!  How did I not know about the 10mm APS-C version?  That is very cool...

Re: 24mm f/1.4 -vs- 14mm f2.8

I've got the Rokinon 12mm f/2 in E mount for my Sony a6000. I love it as it is so much smaller than the Rokinon/Samyang full frame lenses designed for DSLRs. It is a very good AP lens, even better than the 14mm but it is APS-C only and only works on mirrorless type cameras.

Re: 24mm f/1.4 -vs- 14mm f2.8

Here is a quick photo of three of my Rokinon lenses for size comparison. The left lens is the 24mm f/1.4 made for FF DSLRs, the middle lens is the 14mm f/2.8 made for FF DSLRs, and the right lens is the 12mm f/2 in E Mount for APS-C cameras. All three are shown here ready to go on a Sony E or FE mount camera. Subtract about 1" in length for the 24mm and 14mm if you use them on a Canon/Nikon DSLR. The 24mm is heavy, the 14mm is also fairly heavy, the little E mount 12mm is fairly light.

Re: 24mm f/1.4 -vs- 14mm f2.8

It is definitely worthwhile to have both, but if only one I'd definitely choose the 14mm f/2.8 It's part of the reason why I invested in a Nikon 14-24mm f/2.8 because I have the best of both.

I'm so glad I took my 14-24 out with me the other week when we had the Aurora Borealis in the UK because I nearly just took my 24-70 with the thinking that the aurora would be too low in the sky to warrant such a wide fov. Because the aurora ended up being so strong, even overhead at times, the ultrawide angle was absolutely necessary.

Thank You!  Very cool about the e-mount as well....  And the size...
