Should I use screw-in or square ND filters for landscape work in the field?

I currently carry a circular polarizer and a screw-in 4x ND, but I often need stronger ND filtration and stacking with the polarizer is not ideal. I'm considering moving to a 100mm square filter system so I can compose and focus first, then add the filter, especially for darker ND filters. I also shoot with lenses that may use different filter sizes, so adapter rings are appealing. Are square systems generally more practical than screw-in filters for field use? Are there quality options beyond basic Cokin-style resin filters, and when does it still make sense to keep a screw-in circular polarizer?

I think you can only get subjective answers on this, different things will appeal to different people. I'll give you my experience.

  • I have a polarising filter on my main lenses rather than a UV. If it's low light, or I otherwise don't need it, I remove it temporarily, but it always goes back on. I use the polarising filter all the time, so I don't like to fumble around for it. I don't think I could get used to using Cokin style polarising filters, as often as I use my screw in ones, because it would slow me down I think.

  • for ND filters, I do use the 100mm Cokin style. I find they scratch pretty easily, and so I've bought inexpensive chinese ones (Tian Ya). Unless I'm set up to do a lot of images in one spot, I rarely bother to put on the holder - instead I usually hand hold the filter over the lens. The one Cokin style filter than I think is indespensible is the grad ND. It's just not very versatile in a screw in form - graduation is dead centre and you can't move it if your horizon is 1/3 from top or bottom for instance.

  • I have considered buying an inexpensive vary-ND. I don't have high hopes that the quality will be that good. Even with Singh Rays you can get vignetting and funny color shifts at extreme densities and with wider angle lenses.

  • I find the Cokin style filters are bulky, awkward to carry in my bag, and as a result (apart from occasionally pulling one out and holding it over the lens) they don't get as much use as I'd like. I tend to do a lot of walking/hiking, so I don't tend to take a tripod and take the time to set up properly, so maybe it's just me. If I try to use the Cokin holder and filters I end up fumbling and dropping them, getting finger marks all over them, scratching them. Something to think about before you buy expensive glass ones - all depends on you and how/where you work.

  • I have a thin holder on my 12-24mm and I get very slight vignetting in the corners at 12mm. If you do a lot of WA shots, you may want the larger format (170mm?).

  • a lot of people I know think Lee make better filters and holders, but I've not tried them out myself.

There isn’t one universal “best” choice—it depends on how you work. Based on the answers, a common setup is: keep a screw-in circular polarizer, but use a 100mm square filter system for ND filters.

Why square filters help:

  • Easier to compose/focus first, then add a very dark ND.
  • One filter set can work across lenses with different thread sizes using adapter rings.
  • Better for stacking and for future use with graduated NDs.

Why keep a screw-in CPL:

  • Many photographers use a polarizer frequently and find screw-in CPLs faster and less fiddly than a square-system polarizer.

On systems/brands:

  • Cokin-style systems are popular for flexibility, but cheaper resin filters can scratch more easily.
  • Lee’s Foundation Kit was specifically recommended as a sturdier, more versatile 100mm system, with options for higher-quality filters including glass.

So, if your main need is stronger ND in the field and compatibility across multiple lenses, a 100mm square system is a strong choice. If you use a polarizer often, keeping that as a screw-in filter still makes a lot of sense.
