Pros:

Multi-Pack Variety: The inclusion of four filters in this pack, ND8&PL, ND16&PL, ND32&PL, and ND64&PL, provides a versatile range for different lighting conditions. This is especially important for capturing the best shots in varying situations.

Neutral Density (ND) & Polarizer (PL): Combining ND and PL effects in a single filter is efficient and convenient. ND reduces light entering the lens, while the polarizer eliminates glare and reflections, making it ideal for outdoor and water photography.

High-Quality Glass: The multi-coated optical glass of these filters ensures that they won't compromise image quality. You can expect clear, sharp, and vibrant photos and videos.

Easy Installation: These filters are designed to fit your DJI Osmo Action camera seamlessly. They can be easily attached and removed, so you won't waste time fumbling with setup.

Protective Case: Each filter comes in a durable protective case, which is a nice touch for keeping them safe when not in use.

Cons:

Price: Although the quality and versatility are great, this filter pack is relatively more expensive than some alternatives. However, you get what you pay for in terms of quality.

Limited Compatibility: These filters are designed specifically for the DJI Osmo Action camera, so they won't work with other camera models.

This is a set of 4 x Neutral Density optical glass filters for the DJI OSMO series of action cameras.They are packed in a sturdy and impact resistant mattress plastic case with individual cut outs for each filter. The filters all look the same in their case so once you have determined which is which I would endeavour to be disciplined about putting them back in the same hole to save time later. They are all labelled on the outside rim, but you cannot see that from the front.To install the filter you simply push it on over the original clear OSMO lens cover. It feels a bit weird the first time but once yo get the hang of it it is very quick.Optically these seem to be great, I didn't notice any additional flaring and they resist greasy finger marks. I have posted a pair of photos to show a possible use. Both images are the same scene except the darker one is the ND64 or -5 stops filter. As you can see it effectively acted as an iris shutting down the exposure to leave a moody scene. So these can be used indoors and outdoors to control what the camera sees. A very useful and creative tool to have.

These are good ND lenses for your camera. They just friction fit on to the lense and seem to hold well. They give a good range of filtration and look great when you watch the footage back compared to the existing setup.Overall I do like these, my only gripe is that it’s hard to see what filter you are getting out the case without taking each one out and reading the side. They would be better in case that they just slot in sideways. Also I don’t know how well they will hold for action sports as I’ve not been able to try that yet.
