The Sensei holder system is a dream to use for my landscape work. The 86mm filter threads allow me to easily use my filters with each lens while leaving the adapters on each lens. The threads also allow each lens to have secure 86mm caps. I just move the Sensei holder as needed. I use the thin B&W xs-pro kaseman htc polarizer but be aware that even this thin filter takes up 2 slots of space leaving only the third slot for ND filters in the holder when the polarizer is used. I am extremely pleased with the Sensei adapters as they save me time and money compared to others I have used. No vignette using the three slots even at 16mm ff canon. Believe me when screwing around in cold windy conditions this system is easier and faster to use than hitech and cokin.

I bought these because B&H struggles to keep the Lee soft edge set of NG filters in stock. Of course about a week after I took deliver of these filters I got a notification that the Lee filters were in stock. I used these filters in Mount Rainer last week and they worked well for me. What I don't like is the cheap plastic case that these filters come in. Buy I already owned a Lee filter holder so this wasn't a big deal for me. I didn't see any color bias unless I had a polarizer on the lens while using these filters.

As a an avid hobbyist on a budget, I felt this package would be a good compromise between quality and cost.  VERY pleased with the choice so far.  Product arrived in pristine condition - although I noted from a prior review from someone they received a flawed filter.  

Am still experimenting (in use with a Nisi V5 filter holder on a Nikon D750).  Excited about the effects - no perceived unnatural warmth or coolness in the tones.  Unfortunately, the photographer behind the camera still seems to be the weak link . . .

My only comment (not criticism) is to emphasize that these products are resin, not glass.  While you need to be painfully careful with any filters in terms of scratches, you need to be even more so with this softer substrate.  A good quality filter holder (e.g. Ruggard) is a must - not an option.  In short, as much as I like these, when (not if) they get scratched, I will likely replace them piecemeal with glass filters.  But these are the right place to start.

These adapter rings are well manufactured and screw on smoothly. Theres not much else to say; it fits my ND filter frame and adapts it to a couple newer lenses I bought that take 62mm filters (I already had 55mm and 72mm adapters). I like the system so it was worth investing in this adapter for the new lenses.

Como fotgrafo de naturaleza y paisajes, tengo dos juegos de filtros degradados de estos, uno de 125mm y ste ltimo, junto con un kit de ND degradados reversos, para atardeceres. No presentan color como algunas otras marcas del mercado, y son muy resientes y fciles de usar.

Filter wallet holds filters securely and safely. Dont open upside down! Fits both square and graduated filters. #sweepstakes

Its a nice piece of hardware.   Its machined with love  and has a nice finish.  It attaches easily to the lens, rotating on and off smoothly without the annoying grittiness you get from cheaper filter threads. It fits the 82mm attachment ring perfectly and goes on and off just as nicely. Im glad I got it.

Used these filters to shoot Mt. Top sunoise. Great quality and price.

Large enough to put all size lense
