Sekonic L-858D-U Speedmaster Light Meter - SE401858
With it's 2.7" color touch screen and truly innovative and sophisticated features, the Sekonic Speedmaster L-858D-U leads the way to the next generation of light measurement control as the world's first multi-function light meter for photographers and filmmakers. Leveraging over 60 years of experience in the image-making world with cutting-edge technology, the Sekonic Speedmaster L-858D-U has undergone a significant design change and boasts a comprehensive feature set sure to meet and exceed the demands of today's photographers and filmmakers.
The first meter of its kind capable of measuring flash duration, while also being able to achieve an accurate ambient exposure reading in dimly lit scenes as low as 0.1 lx, the Sekonic L-858d-U provides image-makers of all levels with the critical exposure data they need to create stunning and beautiful imagery.
The first to provide wireless compatibility with Elinchrom, Phottix, and PocketWizard products, the Sekonic Speedmaster L-858D-U also provides ultimate control to photographers seeking a faster and more streamlined workflow. Limitless creative possibilities are within reach through the meter’s ability to measure High Speed Sync (HSS) and calculate proper ambient-flash exposure for precision flash exposure control.
With an increased light-sensitivity and extended ISO and Shutter Speed Ranges, the Sekonic Speedmaster L-858D-U enables all image-makers to obtain measurements in extremely low light and turn those readings into creative decisions. Finally, matching the high-ISO capabilities of today’s cameras, by accurately metering in low-light, is finally possible.

Soothing, refreshing, and effective for most uses
I found this sunscreen back when it was still reasonable priced ($10 for a bottle this size) and am now completely 100% addicted as the price continues to rise. Sigh. I don't use this anywhere but my face and neck.
Putting this on my face makes me go "ahhhhh". I break out easily, burn easily, and haaaate the feeling of sunscreen. Previously, I used Neutrogena 45 or 55+ ultra-sheer dry touch, and I still use that sometimes when I expect more intense exposure, but the Coola cucumber just feels so much better.
I don't actually know if I would burn in cases where I still use my other 45+ sunscreen since I haven't taken the chance. I use Coola for 30-45 minute pool sessions, and hikes between 30-90 minutes. I haven't trusted it for things like skiing, 3 hour hikes, or boating where you get intense sun and a lot of moisture exposure.
Buy if you want a lightweight, refreshing face sunscreen for walks in the sun, lounging poolside, or mild-moderate hikes.

Organic Sunscreen with an Air-Brushed Finish
I've been using the Coola Organic sunscreen on my face for about 5 years now. I love that it protects my skin without dangerous chemicals. The product has virtually no scent and has a pleasant creamy, but not greasy, texture. An additional perk is that it creates an instant "air-brushed" looking finish to my skin.
Note: I have found that you have to shake the tube (especially when new) or else the product emerges a bit watery at first.
I've always used the non-tinted formula so I can't comment on how the tinted formula works. Also, the "cooling" aspect of the product seems more of hype than reality. But, over all, this is an excellent sunscreen.

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.
