Overview


The 40mm F1.4 DG HSM Art is Sigma’s first lens developed originally to live up to the sought-after angle of view and performance standard for a benchmark cine lens. This lens effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration. Designed for exceptional sharpness at maximum aperture, this lens excels at available light photography. With less than 1% distortion and near non-existent sagittal coma flare, this lens demonstrates consistent optical results featuring both 8K-compatible resolution and a beautiful bokeh. The Sigma 40mm F1.4 DG HSM Art is available for Sigma, Nikon, Canon and Sony E mount camera systems.

Lip balm with sunscreen
Size: 0.15 Ounce (Pack of 1)
Love this balm and use it almost daily.. I buy it specifically for the sunscreen in it. It goes on smoothly with a light shine. No stickiness or feeling heavy. The tube is a nice size to hold on when using and lasts for a long time.

Refund please - I did not order and/or receive this item
Size: 0.15 Ounce (Pack of 1)
I was charged for this item, but I did not order or even received it. I have written via the "return" page my situation and requested a refund to no avail. The items is actually a great item, and I have ordered it in the past and like it. However, I'm frustrated to be billed for something I didn't order and/or even receive. I hope this results in a refund.

Solid performer lip SFP.
Size: 0.15 Ounce (Pack of 1)
I’m outside constantly. Walking and training dogs. Working in the garden. Playing pickleball. I needed a good spf lip balm that was easy to put on and did not taste perfumery or gloopy. This one is great. I LOVE the little canister that screws on and off so it doesn’t pop off in my purse. And the consistency is stable despite heat and cold.

Great Sun Protection but Texture Could Be Better
Size: 2-Pack (0.15 Ounce each)
The Dermatone Mineral Lip Balm provides really good SPF 30 protection and keeps my lips from getting sunburned during outdoor activities. I like that it’s reef safe, oxybenzone free, and made with mineral-based ingredients, which makes it feel like a healthier option compared to many other lip balms. It does a decent job moisturizing, and the compact size is convenient to carry anywhere. However, the texture feels a little thicker and waxier than I expected, especially in cooler weather. It still works well overall, but I wish it applied a bit smoother. For anyone needing reliable sun protection for their lips, this is still a solid product worth trying.

Great spf lip balm
Size: 2-Pack (0.15 Ounce each)
I use some of their other products when hikig and mountaineering. This lip balm compaired to their others is less mediciney but still does a great job of protecting your lips from sun burn. It goes on hard and lasts all day.
