The 4 x 5.65" ALPHA-I Solid Neutral Density 1.2 Filter from IDX System Technology is an ND filter with a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, each glass surface includes multiple layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. This filter is constructed from optical glass for clarity as well as color fidelity, and measures 4mm thick.

Compatible with filter holders that can accommodate 4mm-thick, 4 x 5.65" rectangular filters.

Lightweight, Flawless Coverage & Reliable Sun Protection A Daily Must-Have!
Color: Tinted
I’ve been using this sunscreen for a few weeks now, and overall I’m very impressed. The texture is extremely lightweight and fluid, which makes it easy to apply evenly without feeling or greasy on the skin. It absorbs quickly and leaves a soft, matte finish that works well under makeup.

My favorite Sunscreen
Color: Tinted, Color: Tinted
I’ve been using La Roche-Posay Anthelios Ultra-Light Fluid Facial Sunscreen SPF 40 for a few years now, and it’s still one of my favorite daily sunscreens. The formula is truly lightweight and absorbs quickly without feeling greasy or heavy on the skin. It layers well under makeup and doesn’t leave a noticeable white cast, which I really appreciate. I also like that it provides reliable sun protection while still feeling comfortable enough for everyday use. Even after trying other sunscreens over the years, I keep coming back to this one because it works so well for my skin. Highly recommend for anyone looking for a lightweight, non-greasy daily sunscreen.

good protection
Color: Tinted
This product protects really well and gives my face a nice, bright tint that looks natural and healthy. It is a little on the pricey side, but honestly it’s worth it for the results. I’m very happy with it

SPF ☀️ for Everyday Use 🧴🌸
Color: Tinted, Color: Tinted
I’ve been using this SPF for almost 2 years now and I still love it! The tint adjusts beautifully to my skin tone and gives such a natural, healthy glow without looking heavy or greasy. It applies so smoothly, feels lightweight, and has a very pleasant smell. Most importantly, it doesn’t break me out at all, which is super important for my sensitive skin. I wear it almost every day and it works perfectly under makeup too. The packaging is also super convenient and easy to use, especially for everyday skincare and travel. Definitely one of the best sunscreens I’ve ever tried — worth every penny!
