The cups are working wonderfully, and who doesn't need filters. Great combo. I'm very happy.

I grew up in the latter 1970s, reading the photo magazines and drooling at all of the filters that helped photographers create the wonderful images reprinted in the magazines. But being a teen, I never had enough money to buy filters and film. That was before photoshop and all the amazing things you could do to your photos after they were taken.I love my digital SLR and Photoshop but I still wonder what I could do now if....I guess I don't have to do as much wondering now. This company (and others) manufacture a whole lot of filters for digital cameras. And this really caught my eye. An adaptor for the large format filters. So I ordered it to prepare for using the huge set of filters marketed by the same company.Of the adaptor rings, I'll only need the one 52mm for my camera but it's good to know that when (not if) I pick up another camera, I'll likely have the adaptor to use the filter holder on that also.This itself isn't an inexpensive investment. But the filter holder feels quite well built and it will be the base for every filter I use. It came with two cases: one for the holder and adaptor rings and one for the neutral density filter that came with it. Super protection against accidental breakage.The adaptor plates fit well into the holder and no light slips through (important!)I will only carry the one adaptor ring I need which makes room in the case for additional filters I acquire.I am looking forward to all of the photographic experiments I can now try. The big advantage over shooting film in the 1970s? I can know how my picture will turn out before I leave the shoot!

I live the selection of gel filters included with this product, and the flexibility of the grid system is excellent. This is just what I need for my product photography.

k&n filters do an awesome job of trapping debris and allowing airflow while cutting down on waste... I prefer these filters and will continue to use them. helpful tip: save your old filter to swap out when you trade your vehicle in.

These do a great job. They're very bright and its nice to have the two filters/defusers. I'm using them for Podcast lighting and they do a very nice job.

For the money these are super filters.I do a ton of filming timelapse in hostile environments like Death Valley and volcanic hot springs areas and have destroyed a few filters. These are a good value and if I ruin them it doesn't hurt so bad...

Stop wasting $35 on paper filters and buy this one for the life of your vehicle. This is all you need to know.

Does not effect power or mpg. I buy them so that I do not have to keep buying filters. Easy to clean and oil.
