Hoya proND color shift

Just got a few hoya proND filters - 16, 64, 200, 1000.
Noticed the nd200 (7 2/3 stops) has quite a noticeable warm shift - (about 500k more than the others).
Tried a few different situations,times of day, lighting, always the same result.

Anyone else experienced this, or have I got a bad version?
If anyone else could test their versions it would be much appreciated.:smile:

A7s, quick test, manual white balance, adjusted iso and shutter to get roughly same exposure.

I think I've seen others get this result with the 200 also. Not everyone, but more than a few.
You could try sending it back for a different copy... I think it's worth a shot.

BTW: Nice little simple grey card there, mate. Got a make and model on that? I'd love to grab a few. Thanks!
 
datacolor SpyderCheckr 24 - has 24 color patches on the other side, works with resolve chart match too.

Thanks for the reply! Couldn't seem to find any threads or mentions of issues anywhere.
Hoping its a bad copy. The other strengths are great.

OK, SpyderChecker... yeah, I was looking at that card as a color card but didn't notice what was on the back.

I've also heard of folks having this issue on the 1000 strength, but then you didn't.
I suspect it could be a "batch" thing.
