    Default Which Lens to get Rokinon or Tokina



    Morning,

    Newbie here.... just got the D5600 which will be used on my Star Adventurer. Now I haven't shot anything on this rig yet for I am looking for a lens to put on this camera.

    Now I have been looking at the Rokinon 14 T3.1 or the Rokinon 14 f/2.8 or the Tokina 11-20 f/2.8

    Starting off first doing wide field and I know that this camera is a DX.

    Any recommendations or suggestions for a lens?

    Thanks

    Either of the Rokinion 14mm lenses will be GOOD. The docs on the two are confusing enough that several indicate they actually have the same Internal Lens Configuration - 14 Lens in 10 Groups (that is a LOT of Glass for the Photons to traverse). The differences are in the design of the Aperture mechanism - not really anything to concern your Nighttime Use.
    I have the "Rokinon FE14M-C 14mm F2.8 Ultra Wide Lens for Canon" version from 2016. It is FUN. It has some significant Barrel / Fisheye Distortion - which doesn't really impact Widefield Nighttime Sky Images. It also has some Coma and a minor bit of Chromatic Aberration when you move toward the edges. The trickiest thing is Focusing - at f/2.8 the Critical Focus Distance is extremely Small. And to top it off, you are looking at Stars or even the Moon as nothing more than little Dots - best to perform Focusing while using LiveView tethered to a Laptop.

    As for the Tokino Zoom... I have a slower Canon EF-S 10-22mm f3.5-f5.6. I use the 14mm for Nightscapes, as the Optics are better and no real need for Variable Focal Lengths...

    I have a Rokinon 10mm f2.8 plugged into my Nikon D90 and really like it.

    A sample image for you:




    Also, here's an image I took with something similar using a Canon 7D mark II. Both exposures are 30 sec @ 800, stopped down 1 setting.

    My point is that these lens are quite nice, better than many for what they are (inexpensive). I really like them.




    Kind regards,
    Ian

    The Samyang/Rokinon 14mmf2.8 is a proven performer in wide field nightscape work. Mine can be used wide open at f2.8 on a full frame sensor(Pentax K1). A friend of mine used his on a Canon 6D. He tells me that he has to stop down to f4. With the DX sensor in your camera, you should have no problem wide open.

    Two other good options to consider are the Sigma 14mm f1.8 Art lens and the Irix 15mm f2.4.

    I would only go for the zoom if you need to compromise on a more versatile lens for standard photography.

    The Samyang, Rokinon, Irix, and Sigma 14mm lenses all have full frame coverage if you upgrade to a full frame camera body at a later date. The Tokina zoom only covers APS-C/DX sensors so no use if you upgrade the camera later.

    Cheers

    I should clarify that the difference between my friends lens and mine is possibly individual lens quality variations nothing to do with mount type.

    The Samyang lenses are profiled so you can digitally remove the distortion that seigell referred to in his/her post.

    I'm not familiar with the Rokinon, but I have several Toking lenses and I am very happy with both the quality and the customer support. And they seem very well built.
    Properly collimated cornea-lens-vitreous optical apparatus, projecting on retinal sensor slightly limited by deuteranomaly, feeding through stock optic nerves into functional primary cortex, processed through frequently misfiring and buggy integrative cortex.

Main EPs: ES 82º 24mm, Meade UWA 14mm, ES 82º 11mm, Olivon 70º 8mm, Meade HD-60 6.5mm and 4.5mm. Filters: UHC, 13%, blue. Finders: RACI, Telrad, RDF, reticle.
