Soft Blurry and unusable. Color cast was ok.
Images taken with this filter were extremely soft and blurry. The screen image was taken on a tripod with an appropriately high shutter (1/800) to eliminate movement and vibration. The lizard was handeld with a 1/400 shutter using a 5DM4 & Sigma 70-200 f2.8 sport lens with OS on. The image colors were ok. I assume I got a defective filter. I've had other K&F variable ND and ND1000 filters without the blue layer and they offered normal expected results.

Affordable ND Filter with awesome quality!
Got this filter this morning and immediately was impressed with the build quality. I took it outside to try a few shots with strobes and it did fantastic! I am very happy with this purchase - and with quality ND filters running double, triple, or sometimes WAY more than this, for $39 it's a steal.I didn't notice any color casts or the dreaded X-pattern that I hear from some cheap filters, so that's wonderful!Well made, affordable, and quality photos - what more could anyone ask from a filter? Recommended for beginners or pros.TIP: Buy the size for the biggest sized lens you own, and buy a set of step-down rings so you can use it on ALL your other lenses, rather than needing to buy a different filter for each lens.

Works Great!
The filter arrived early. It's my first time using a variable ND filter and so far it has worked quite well for cutting glare. The construction is solid and it has a nice low profile and does not interfere or add vignetting to my shots. Still learning to use it but I'm liking it.
