It is sensible {that a} model like STC Optics would make sapphire filters, but many of the digicam trade hasn’t carried out it. Manufacturers throughout the tech world use sapphire glass. If in case you have an iPhone, you’ll realize it’s presupposed to be tremendous sturdy. Equally, in the event you use an Apple Watch, you know the way indestructible your display is. Some of the outstanding makes use of of sapphire glass in cameras was the Leica M9-P. It’s one of many issues that helped cement how sturdy that digicam has confirmed itself to be (externally talking, after all)! We’ve heard about Schott glass utilized in filters, however we hardly ever hear about sapphire. So I purchased just a few STC Optics sapphire filters to see how they maintain up.
What are STC Optics sapphire filters?
It’s arduous to make lens filters that stand out from each other. The Japanese and numerous different manufacturers are notoriously secretive about saying a lot in regards to the tech. And that’s as a result of the manufacturers all use the identical glass from the identical set of producers. They’re additionally all utilizing related coatings however calling them various things. Stick round within the picture trade lengthy sufficient, and also you’ll be taught that just about all glass in lenses and filters comes from possibly round 5 firms.
That’s one of many the reason why they haven’t made sapphire filters. Sigma went so far as doing ceramic filters — one other materials utilized in watches. The profit is that ceramic can take scratches buffed out with thumb power and sharpening. They’re additionally fairly arduous to interrupt in comparison with different lens filters. However sapphire glass is even harder to interrupt and scratch. Take it from a man who solely buys watches with sapphire glass crystals.
The standard of the sapphire glass in STC Optics sapphire filters, watches, and your cellphone’s display all differ. Your cellphone has an insanely skinny piece of glass that doesn’t have any safety on it. That’s why all of us use display protectors and bumper circumstances — in order that the display received’t get cracked if it falls.
In distinction, watches have thick sapphire glass crystals. These crystals are thicker than lens filters.
What makes the STC Optics sapphire filters so sturdy, although, isn’t simply the sapphire glass — but additionally the aluminum ring that gives a pleasant buffer zone. The ring isn’t as good as B&W’s brass filters, nevertheless it’s nonetheless terrific.

Heading to their web site, you’ll see that STC Optics sapphire filters aren’t low-cost. In truth, they solely make them in bigger type components. However in addition they make claims of some critical tech. For instance, they converse to the sturdiness of the metallic filter ring. Additionally they particularly listing what number of kilos of drive the filters can resist. Their claims of 800MPa can’t be examined by standard means by my analysis, however just a few different claims may be examined.
STC Optics sapphire filters declare to have an anti-smudge coating. And it most definitely does. Nevertheless, my filters nonetheless certainly received smudged. Nevertheless, they have been simply cleaned off with a microfiber fabric. I at all times carry one once I go away my house. Truthfully, although, most trendy lenses are too scientific for my liking. And a little bit of smudging provides likable character to them, particularly whenever you’re capturing into the solar.
The filters additionally declare to have a hydrophobic resistance coating on them. And that is certainly true. I couldn’t assist however stroll round Queens, NY, as fog and light-weight rain peppered the air throughout New Yr’s Eve. I mounted the STC Optics sapphire filter to my Canon RF 50mm f1.2 L USM and the Canon EOS R5. Thoughts you, I even have stopped utilizing lens hoods for probably the most half and have moved again to solely utilizing lens filters. With this in thoughts, the STC Optics sapphire filter shrugged off any precipitation. Once I say that, I actually imply that nothing received on the entrance coating, at the same time as I attempted to wipe it off and see.
The Longest Second of My Life
At one level, although, when cleansing the filter, I unintentionally dropped one from round 4 and a half toes away from the ground. For a second, my coronary heart seemingly skipped a beat as I proceeded to dwell by the longest second of my life. I imply, I’d simply spent all that cash on the filter, and I used to be certain that it might break. However to my shock, it was completely high quality. Think about the shock on my face!
How Does It Have an effect on Picture High quality?
The parable for years has been that lens filters have an effect on picture high quality negatively. And by that, we imply that it degrades the standard of the picture by softening probably the most minute particulars. However in the event you’re not pixel-peeping, this usually doesn’t matter. The perfect safety is a mix of high-quality lens filters and a lens hood. Discover there how we stated high-quality lens filters. Many manufacturers promote absolute trash, and plenty of photographers need to go for the most cost effective ones. However like all issues in life, there’s a cause why the dearer filters are so dear. On this case, the aluminum filter doesn’t get caught to the lens. Additional, the glass is engineered to be skinny and tremendous protecting.
Is the picture high quality affected? Properly, right here’s some token Chris Gampat brutal honesty. Should you’re going to edit your images or spend extra time in post-production than you’re capturing, it received’t matter. You’re in all probability going to crank the readability slider or sharpness slider as you eyeball what appears to be like good and what doesn’t. However if you need photos that don’t actually want modifying, the STC Optics sapphire filters do a unbelievable job. Right here I’m speaking particularly to Leica, Fujifilm, Panasonic, and Canon customers. Sony cameras typically set you up for desirous to do a ton of post-production. However with different manufacturers, you’re often set as much as get it proper in-camera within the first place. And when strolling round with STC Optics sapphire filters mounted to my Canon cameras and lenses, I did no modifying apart from lens corrections and an publicity adjustment right here and there.
Once I used the filters on my Tamron 35-150mm f2-2.8 on my Sony a7r III, I completely did modifying to my images. However I’m extra prone to blame that on Sony than I’m on Tamron.
Closing Ideas
I’ve been transferring away from utilizing lens hoods as lenses, cameras, and lens hoods have grow to be so massive that I don’t need to carry them round anymore for enjoyable. My former co-worker at B&H Picture, Zevi, used to do that and referred to as lens hoods obnoxious. That was over 10 years in the past, and I began out in images utilizing lens hoods and filters collectively. As of late I exploit one or the opposite relying on whether or not or not I’ve purchased a filter for that lens.
And if I’m utilizing a higher-end lens that I actually care about, I’ll most definitely purchase STC Optics sapphire filters within the close to future, offering they cowl the filter dimension. In any other case, I’ve at all times discovered good manufacturing with merchandise from Urth.
