Has anyone ever encountered this problem (lens issue)
Solved! (See post #17)
Camera - Nikon D500
Step Ring - BT 72-77mm
Filter - Singh-Ray 15 Stop Mor-Slo
Filter - Breakthrough 10 Stop
I can't really explain it other than I'm getting a consistent light pattern on the left hand side of the screen (and image). I link to two phone images below.
I tried blocking the sun with my hand and shooting away from the sun. No help. The light pattern is still there.
I cleaned the sensor and rear and front element of the lens. No help
I swapped the step ring and filter out and put them on my Nikon 16-80mm. No problem with that lens.
I cleaned the filter. No help
I tried a BT 10 Stop ND and the pattern returned.
When I widen the apeture the problem dissipates somewhat but is still there.
I tested the lens w/o filter and its perfect.
I tightened the step ring and filter and still get the light pattern.
I removed step ring and held the 15 stop before the lens. I get the light problem.
Seems like a lens problem. But what problem? Like I said without the ND the the lens is tack sharp.
