matte box & filters

I'm waiting on the Letus Extreme to land on my doorstep and wondering if I now need to buy some ND filters and suitable mattebox.

As I understand it, there's no point in using the ND filter in the camera (XH-A1) if I'm using a 35mm adaptor.

What other filters are people using?
Are they screw on or 4x4?

Actually that is true of many other adapters but with Letus adapters, you can very effectively use the camera's built in ND filters.

There are a few schools of thought on the topic, but once you've played a bit with lens flare, and seen the contrast hit that lens hazing causes, a mattebox and 4x4 filters are hard to beat. Built in ND filters work great to cut exposure, keeping shutter speed and aperture in desired ranges, but they don't prevent non-image forming light from causing issues with your optics out front. A graduated ND filter as well as a polarizer are two extremely useful filters that not only cut exposure a few stops, but also improve image quality outdoors. For example, a graduated ND can be adjusted in the stage to cut 2 stops in a bright sky, but leave the lower half (ground) unaffected. If you point your adapter/lens beneath a lamp so the light is just out of view, try shading the lens surface with your hand for a very visual example of lens hazing and contrast loss. The mattebox shades will stop this, and are a win-win when it comes to image quality.

Once you start using one, you'll never leave home without it. End of "I love using matteboxes" post :-)
