Welcome to our roundup series where we will hit on several gear news and rumor topics each day. This gives you a chance to get caught up on all of the day’s news and rumors in one place. Make sure to check back daily for the latest gear news, rumors, and announcements.

Sigma Announces New Water Repellant Ceramic Protection Filters


Today, Sigma made a major announcement that is all about new glass, but not the lens kind of glass. Sigma’s announcement, in the form of a new line of WR (Water Repellant) Ceramic Protection filters, is the first time that my jaw has ever dropped over a lens filter.

These new filters are impressive to say the least. Boasting ten times the strength of a traditional chemically enhanced glass protection filter, these new WR clear glass ceramic filters are able to take more of a beating than any lens or filter I have ever seen. The following video just underscores that.

See what I mean? These new filters are impressive, and some of the key features are explained below:

  • Scratch-resistant – Sigma’s Clear Glass Ceramic offers a Vickers hardness number of 700HV. The strength of the Clear Glass Ceramic is much stronger than chemically strengthen glass and is; 10 times stronger than conventional filters
  • Thinner and lighter – This new protector is up to 50 percent thinner and is up to 30% lighter than previous Sigma filters
  • High transmittance – Sigma’s Clear Glass Ceramic offers very high transmittance, making it ideal for use as optical glass
  • Water- and oil-repellent coating – The water repellent coating reflects only 0.24 percent of visible light, thereby minimizing flare and ghosting. Its ability to repel both water and oil is also excellent, with water drops bouncing right off, and fingerprints easily to remove

The Sigma WR Ceramic Protector is the latest example of Sigma’s dedication to innovative and first-to-market photography equipment,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The new Clear Glass Ceramic protector is the first of its kind and the strongest material used in the industry. It will enable photographers to safeguard their lenses, while maintaining the impressive sharpness offered by high-quality glass, like our Global Vision line of lenses.

Unfortunately, the pricing and availability for these new filters have not yet been released, so we have no idea when these will be available or how much they will cost. That said, I am still really excited about these filters… and that is not something I thought I would ever say about a lens filter.

Adobe Releases Lightroom Mobile 2.1 For iOS


Hot on the heels of Adobe making the Android version of Lightroom Mobile free to use without a Creative Cloud subscription, they now have a new update for the iOS version. The new features will definitely add some interesting features and functionality to the LR extension app.

Adobe Lightroom 2.1 Features

  • iPad Pro support and support for iOS 9’s multitasking capabilities
  • Point Curve mode for the Tone Curve and the Split Tone adjustments tool
  • Support for 3D touch and a new widget to launch the Adobe built-in camera from the iOS Notification Center
  • New shoot-through presets in the Adobe built-in camera and more.

One of the features that will no doubt stand out to iPhone 6s owners is the addition of 3D Touch support for added app functionality. This will be likely one of the first apps for photographers to take advantage of the new Apple technology.

Those of you with iOS devices who would like to get the update can do so manually here.

    I’m confused on the “ceramic” nature of the lens filters. I have a degree in Ceramic Engineering – and glass is classified as a Ceramic material – do they mean that it is a crystalline structure (if so why not say that)?? Or is it a special heat treatment / glass composition.

      It’s cursorily referred to in the video. They allude to some heat treatment that goes deeper / more completely into the internals of the glass, as compared to the surface-only hardening that most conventional filters get.

    There is this page at Canon Japan:

    Ugh, a flame war is certain. UV/Protect filter discussions only bring out the zealots.

    The continuing argument about “lens protection filters” is about to heat up again. Sigma is the second major camera brand to promote protective filters. Canon, was the first to mention that clear filters, would enhance the weather sealing of their “L” quality lenses. Now, Sigma embraces the protection filter, for their high quality “Art” lenses. I, for one have always used a protective filter for the outer element of my EF, and EF-S lenses, “L” quality, and 3rd party lenses. Just the fact that Sigma has come out with a “protective filter”, but a armored version is “jaw dropping”

      I can’t speak for Nikon or Sony, but sealed Canon L lenses with front filter threads require a filter to seal those threads from becoming an ingress point for moisture and small particulate.

      So, as I understand it, those lenses are indeed sealed, but the feature of offering a front filter ring introduces a weak point in that sealing. So even if you hate UV/protect filters, they are a good idea in driving rain, misty/spray conditions, etc.

      I can’t see the appeal for regular photography but I can in some instances like weddings. I usually remove all the caps, everything is sitting in a bag ready to be swapped if needed. I’ve never scratched a lens before but I do sometimes wonder about a protective filter for “just in case.” Just seems weird spending a few thousand dollars on glass only to put a cheap piece of glass in front of it all. Maybe that’s just me.
