K&F Concept 100X150mm Square Soft GND8 (3 Stop) Soft Graduated Neutral Density Filter with 28 Multi-Layer Coatings Waterproof/Scratch Resistant/Anti-Glaring

This filter is awesome. The gradation from ND8 to clear is perfect with no distortions in image or color shift. My ONLY gripe is that in order to use it with the K&F System you need to use the frame for it to fit. The fit in the frame is fine, however once in the frame the filter no longer fits in the nicely made protective case. Trying to take the frame apart after each use to store the filter is a waste and could lead to breaking the frame or filter making it useless. If you're reading this K&F, make the protective case roomier to accommodate the filter and frame. Otherwise, fantastic product.

Compre varios de los filtros de K&F, y si bien, la marca en materia de trípodes decepciona, compensa en demasía en materia de filtros. Este kit es excelente, a nivel de calidad óptica, y de materiales.No tienen casi color cast o aberraciones cromáticas, asi como no pierde nitidez la imagen.Realmente recomendable, sobre todo porque el ND1000 puede competir cabeza a cabeza con un Lee Big Stoper, y dar mejores resultados por una fracción del precio.El único contra que tiene como todo KIT es que no trae un estuche para guardar todo (el estuche de K&F se vende aparte y es bastante chico para mis necesidades).

I purchased this grad filter for shooting cars in direct sunlight. I got exactly the effect I was looking for. The car properly exposed with the sky not blown out. This filter is of high quality glass and the mount system is well designed without being overly complex.

This filter is super high quality, I used it both for video and photo. For video I used it to expose the sky and the foreground. Especially if you own a cheap dslr this filter will make it look like you have a cinema camera. Highly recommend it.

The fit is so tight into the K&F holder that it is impossible to insert and remove. I fear that I will end up with a handful of broken glass and be severely injured. You certainly would not be able to adjust the grad level while on the camera due to this very poor fit. I purchased this along with the filter holder and 10 stop filter from K&F. You also have to struggle with the ten stop but it is smaller and easier to handle. You would not be able to swap out a filter easily with the 10 stop as well. I am highly disappointed in the whole system at this point and will be sending everything back.
