https://www.youtube.com/watch?v=mIJnUuIhy-wI have used the Nisi Filter System for over a year now and think this is the best system out there.To start you pick up the V5 Pro kit for $180 - I recommend you purchase from B&H Photo This includes a nice protective case, high-quality circular polarizer that is integrated into the 82mm ring, the filter holder and adapter rings (that allow the holder to be used with lenses that have 67mm, 72mm, or 77mm front filter threads. Additional rings are available for purchase)I recommend you add:

Nano IRND 1.8 Filter (6 Stop) [Buy from B&H Photo]
Nano Soft-Edge Graduated IRND 0.9 Filter (3-Stop) [Buy from B&H Photo]

The 6 stop allows you to easily do long exposures in cloudy conditions or near sunrise/sunset. If you want to achieve long exposures in bright conditions pick up the Nano IRND 3.0 Filter (10 Stop) [Buy from B&H Photo] The Nisi V5 Pro holder is their latest edition and it's improved over the original. Earlier models were very difficult to slide the glass plates in/out of and this updated version is much better while still holding them securely in place.Advantages of Nisi over LeeThe NISI system comes in a nice leather carrying case everything is protected and a silent soft magnetic latch makes it easy to access. Downside - it is a little bulkyNisi offers an integrated circular polarizer often times when I'm using these filters I'm photographing water and I do want to use a circular polarizer to control or cut the amount of Reflections and it's so easy to rotate with little dials on the edge of the filter holder.The Nisi system comes with a variety of adapters that allow you to use it with lenses- 67mm, 72mm, 77mm, and 82mm Adapter Rings. Additional adapter rings are available for purchase. Quality - Extremely sharp and no color casts. I found the Lee system to have strong cool or blue color casts in their stronger ND filters. Why do I recommend the NISI system over stacking several circular filters?

Flexibility- this system allows me to use graduated filters AND circular polarizers together and easily.
no vignetting even on my widest lenses.

Don't waste money on UV Filters
In general I am not a fan of UV filters, they offer little protection from a fall and the glass at the end of your lens is pretty tough, it's not going to get scratched unless you are very careless. I prefer lens hoods as they do offer some protection from falls and nicely protect the end of the lens from coming into contact with random objects without degrading image quality. I do prefer camera brand lens hoods, I have tried a few of the third party and they often fit just a bit awkwardly making the putting on and taking off just a bit slower. Some of the very cheap 3rd party lens hoods actually use the filter threads to attach, this is bad as it blocks you from adding a filter and is very cumbersome to put on take off.

Circular Polarizer Filters are useful
The one filter I do recommend landscape photographers own (or anyone taking scenic view photos) is a circular polarizer (CP Filter). Some benefits of a CP filter include:

CP filters reduce reflections and glare
Reduces Haze and blue cast in landscapes
Adds saturation to your sky and greenery

Recommended Hoods and Polarizers for Common Lenses

More about CP filters. There are other specialized filters worth owning for some situations but a CP is one that many don't know they need and gives you a look that is not reproducible with post processing. The brands I list I find to be safe choices at each of those price points, there are certainly other brands/choices at each price point.Roll your mouse over the image to see the effects of using a circular polarizer ( no other changes were made - I simply rotated the circular polarizer from what I call zero effect to maximum effect)[himage][/himage]Scroll to the bottom for a plan to save on filters.

Instead of buying a filter or filters for each sized lens you can but this set of step UP adapters and then buy the largest filter(s) you need and use the adapter(s) to fit to each of your smaller mm lenses. So in this example you would buy filters in the 67mm size and use the 67-62 + the 62-58 adapters to use that filter on your 58mm lens. And throw on the 58-55 and the 55-52 to step down to the smallest lens in this example. Truthfully I have never used more than one at a time but there isn't any reason why it shouldn't work and these adapters are glassless, so nothing extra between you and your filters.

Fotodiox 7 Metal Step UP Ring Set, Anodized Black Metal. 77-72mm, 72-67mm, 67-62mm, 62-58mm, 58-55mm, 55-52mm, 52-49mm
