Samyang 500mm Lens damaged?
Posted: Fri Mar 21, 2014 5:49 pm
Hello BM users,
I just purchased the Samyang 500mm f8 lens for my telephoto wildlife videography. I just received it in the mail today and put it on my bmcc.
It was then that I noticed when I stopped the lens down dark distinct smudges would appear (this is an image of the clear blue sky)
I immediately assumed it must be dust on the sensor or lens. However when I checked both they were entirely clean;
I double checked the sensor as well, putting on my sigma 18-35 and there were no dark smudges. So do I just have a bad lens that needs to be sent back or is there some way to fix this?
