I don't, as a matter of fact I stopped using mine for anything. It certainly is not anywhere close to being capable of astrophotography.


I have not used it for astrophotography.  I have found the manual focusing Rokinon 14mm T3.1 to be more useful for shots of the night sky because of its' focus scale and manual aperture ring.  It is impossible to adjust aperture when an electronic aperture lens is set to MF, and I do not want to switch it to AF.

 

The only drawback with the Rokinon is that it may be too wide, and creates barrel distortion on the edges.  This is not much of a problem with a single long exposure.  It becomes an issue when you start tacking photos, and auto aligning them.

"... the Rokinon is that it may be too wide, and creates barrel distortion on the edges."

 

I would like to see a sample photo.  I no longer do sky photography. I only hear the results from my friends that do. I was into it heavily for a few years. I was a charter member of the Powel Observatory. When it moved to Missouri I pretty much quit.

Several of the Rokinon lenses are favorites.  Sometimes you have to get several to many before you get a good one. However when you get a good one it is good.

 

"...it may be too wide..."

 

When it comes to capturing the night sky, a camera lens that is fast and wide like the 14mm Rock works well.. You can capture much more sky and that is the purpose of such a lens. Now if you don't want a wide angel sky it may be too wide.  Usually not the case.

 

"...creates barrel distortion on the edges."

 

If all you do is shoot landscapes it doesn't matter.

You just love to take a few words out of context and apply your own meaning to them.  Have you ever tried to auto align and stack photos.before?  It sounds like you may have forgotten what is involved.

Actually, my thoughts was, I truly doubt you have done any astrophotography. And, no, the Moon doesn't count.

The above image is from the Tamron 15-30 f2.8 G1 verson of the lens on a canon 5DM4, 30 second exposure, 2k ISO, manual focus, remote shutter release. Yes, there is fringe distortion which can only be corrected to a point. However, when not using recognizeable elements at the edges I find the lens more than capable.

Re: Looking for a recommendation for a ultra-wide angle lens

Thanx for the example.  You have the G2 version to be clear?  I had the SP, I know of no G1 but I may have missed it.

It is a gorgeous shot, you can be proud of.
