Tiffen Variabler Graufilter ND 77mm

Was looking for a filter that I would be able to shoot 180 shutter speed during the day and it works just perfect

Ive only used this new tool a few times but so far it works great. No noticeable color shift even at Max. What I really like is it give me the ability to make a change while shooting that is far less noticeable than changing ISO. If the sun goes behind a cloud, I simply dial in less ND and its smooth enough that it looks like a good aperture change, maybe even better. This is a typical Tiffen high quality unit.

I really like this filter. The only downside is the crazy color cast in the corner of the frame when you place the filter mark on the last dot and the maximum label. This kind of color cast is normal for variable ND filters, so it is ok, I just have to be careful while recording.

This was the best fit for my needs. Saves on buying multiple filters and no degradation with image quality.

Got this for my Olympus 12 - 40 for the GH5. It has a nice range. Of course, at the end of the range it gets wonky but thats expected for a variable ND. In all, nicely clear and with negligible color casting except a slight warmness. Just grade stuff and youll be happy.
