Question 1

Would this lens be great for night star shots? It focuses to infinity correct?

Accepted Answer

I just got this lens for astrophotography and decided to see if I could find where it focuses the sharpest when capturing stars. I took a series of shots with the focus set as far into infinity as it could go, then I backed it off about 1mm for each shot (at ~30 seconds shutter speed) while the focus ring was inside the infinity line. After reviewing the shots in Lightroom, I honestly can't see much of a difference in sharpness between the shots. The scene included a well lit object about 1 mile away and a generous portion of the Milky Way as well as Sirius and Canopus, and even zoomed in all the way, the stars and the lit object have about the same amount of sharpness through the series of images. I plan on duplicating this setup but at a shorter shutter speed to see if I can spot a difference, but so far it seems sharp in the whole "infinity" range. This blows my Canon 28mm f/1.8 out of the water completely for astrophotography (at a savings of ~$200). The Canon is fairly useless over f/2.8 anyway because you get a ton of coma around the edges of the image, so the wider aperture doesn't help. The Rokinon has no noticeable coma at the edges at f/2.8 either.

Question 2

I am very interested in this lens, will it fit my Canon Rebel T3?

Accepted Answer

Sure it will fit the Rebel T3 - keep in mind that this is a manual focus lens, but a very sharp lens

Question 3

Is this lens good for star photography?

Accepted Answer

Yes! It’s manual focus so I suggest using your led screen and led zoom function to get sharp focus of a star or planet. Screen mode or whatever it might be called on your camera. I’ve had good results and astrophotography is what I bought this lens for specifically.

Question 4

I have a Canon 5d Mark ii. will this mount on my canon 5d Mark ii?

Accepted Answer

Yes it will, fits perfect on my Mark iii.
