I went to take night sky shots tonight and found a weird thing about my new Samyang 16mm F2.0.
It's not easy trying to focus on stars with a manual lens and this lens made it harder.
I took half a dozen shots set to infinity then uploaded them the my computer and discovered they were all very out of focus.
So then I went back out and took another 10 shots, moving the focus ring slightly away from infinity with each shot.
I found true infinity to be a long way from where the ring actually stops. Now I know some lenses can be slightly of the mark but I feel this one is just too far out.
Ok so I thought I might check the other end just to see what happens.
The specs for this lens say closest focus is at 20cm, well my copy will focus at 8cm. That's a bonus that I like, but one of the main reasons I purchased this lens in the first place was for star shots and the way the focus ring markings are placed makes that a real chore.
Now for the pics.
First one shows infinity stop.
Second one shows actual infinity position.
Third is close up stop.
Should I send this lens back and get a replacement ?
