Very nice example of this lens at its finest.

+1. I am very interested in seeing what this guy can do.

Thanks guys.

Please note that you can use fisheye hemi to de-fish this lens and get a huge straight image.
It does take some work, but it's amazing.

I understand this is a manual focus lens.

Will the camera beep when the subject or scene is in focus?

No. The camera has no idea if you have focused or not. It will meter the scene but as for focus, you are on your own.

If I don't get the shots I want with the gear I have, the only optics I need to examine is the mirror on the bathroom wall. The root cause will be there.

I hardly see the focus being any kind of issue. At such a wide focal length anything ft away at F8 should be in focus.

Its 399.99 right now and I am very tempted. I just bought a 16-35F4L IS, i dont think I can get away with two in a month. :-(

how many feet away does a subject have to be before the infinity focus applies to the subject?
im tempted to get this or the rokinon 14mm

I can try to explain in my crappy ways or let the pros do it :)

This will help,

just be aware that going all the way to the end of the focus ring, does not mean it's focused to infinity at the sharpest.
I only have one lens that is that well made and it's not samyang...

With both this lens and the 14/2.8, I put it in live view, zoom in and do a quick manual focus. Just takes a few seconds.

This is brilliant. Never thought of focusing in live view and then shooting. I shall try that this evening. Thanks for the tip.

I went to B&H Photo video. the guy i spoke to was not very helpful at all.
they have both a Samyang 12mm f/2.8 and a Rokinon 12mm f/2.8. They both look the same, IMO the Samyang felt slightly heavier but to be honest it may have just been my mind playing tricks. Regardless, what is different between the Samyang brand and the Rokinon brand? They seem to be the same, but why make two brands of the same item? Are there any technical differences to know about?

In other words if i am making a purchase which of the two should i purchase? the samyang or the rokinon brand? or coin toss?

Same exact lens. Samyang is the manufacture and bower, rokinon, etc all rebrand it. I personally prefer Rokinon better for some stupid lame reason. It doesn't matter and both are identical.

First astro w/ the 12mm. Top image is SOOC and the second is edited... obviously I sharpened it way too much.

back to the drawing board.
