Chiaro 99-UVBT72 Overview

  • 1Description

The 72mm 99-UVBT UV Filter is Chiaro’s top-performing protective UV filter offering 99% light transmission. It’s ideal for photographers who demand the highest-quality glass and other essential features for uncompromised image fidelity and premium construction.

To achieve superior 99% light transmission, Chiaro uses highly-polished Schott glass, multi-coating, and additional advanced elements that improve the filter’s light transmission. A scratch-resistant coating minimizes scratching of the glass and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. The durable brass filter ring is designed to screw on and off effortlessly, and it’s thin to prevent vignetting when used with wide-angle lenses.

Image quality is what matters most at Chiaro. The company has tested and combined many features and essentials to achieve superior image quality and the highest light transmission. To help take the confusion out of selecting a filter, Chiaro prominently displays the light transmission levels so that you can choose the perfect filter for your lens and photo session.

99% Light Transmission
Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished Schott glass and advanced coatings, Chiaro can offer a 99% transmission rate, which is the highest possible transmission rate for glass. And the company verifies the ratings with ISO certified lab testing.
Resistance Coating
The layers of advanced resistance coating on the filter are designed to resist moderate scratches, and allows you to easily clean your filter. Water beads up and rolls off your filter, and oil and fingerprints can come off with a gentle wipe. Dust and debris won't adhere to the filter and can be removed with a puff of air.
Polished Schott Glass
Glass that's polished to perfection is essential to achieve a high level of light transmission. The Schott glass in this Chiaro filter is highly-polished for flatness that ensures superior optical clarity.
Multi-coating enhances light transmission to the demanding level we set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images.
UV Protection
The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.
Brass Construction
The durable brass filter ring offers a substantial, premium feel. The unique properties of brass minimize the chance of jamming or binding when you're screwing the filter onto your lens or stacking filters.
Slim Design
Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.
Top Knurling
Top knurling offers a firm grip on the filter when you're attaching or removing it.
Secure Attachment
It takes two full turns to mount the filter on your lens. This feature will securely hold your Chiaro filter through the most demanding photo shoots.
Front Threads
The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.

    Chiaro 99-UVBT72 Reviews

    72mm 99-UVBT UV Filter is rated 4.8 out of 5 by 17.
    Rated 5 out of 5 by from Chiaro UV filter put to the test in Grand Canyon I normally don't use filters. Why put an extra layer of glass over my expensive lenses. But the Grand Canyon is an extreme environment that is tough on cameras and lenses. I put these new UV to the test with the silt, sand, and water in the canyon. The optical quality is superb. And I'd much rather keep cleaning my filters over and over than the front element of my lens. They have earned a place in my filter kit. Thanks B&H! Do great work, @RalphLeeHopkins

    Rated 5 out of 5 by from Protect your glass with Chiaro Everyone should have a UV on all their lenses - just for the simple reason of protecting your expensive lens against dirt, dust, and smudging. Chiaro offers the ultimate in protection without the loss of image quality. The 99-UVBT uses the same Schott glass, multi-coatings, and resistance coatings as the top of the line 99-UVBTS - the only difference is in the knurling. BT is knurled just at the top while the BTS is knurled on the top and sides. I do prefer the BTS for the best grip but if you want to save a little cash ($8 for the 62mm) then the BT will most likely serve you well into the future!

    Rated 5 out of 5 by from Quality filter in harsh conditions I photograph in a variety of conditions, and some of those places can be rough on my gear. Blowing sand and dust, saltwater spray, and rain can make for great images but protecting my lenses from the elements is critical. The Chiaro UVBT UV filter does that job well. It is easy to clean and doesnt bind up on the lens when attaching or removing it. Most of all though, this filter provides reliable protection for my leness without compromising the quality of the resulting images. I would recommend this filter to anyone who is looking to protect their high-end lenses.

    Rated 5 out of 5 by from Keep it clean with Chiaro I love the Chiaro range of filters. They offer premium products at a variety of budget ranges. This is their 2nd best filter but really the only difference between their top of the line 99-UVBTS and the 99-UVBT is the knurling which is only on the top of the filter whereas the BTS has it on the sides and top. You can save yourself $5-$10 with this top only and still get the excellent image quality, coatings, and brass ring. If you aren't stacking a multiple filters this is a great way to save a little cash.

    Rated 5 out of 5 by from Great Filter! Bang for your buck, this is one of the best UV filters on the market. 99% light transmission, polished Schott B270 glass and brass construction that prevents the filter from binding on the lens. The only difference between this filter and the UVBTS is the knurling - or grip - is on the top only, versus the top and the sides. In my opinion, if you are willing to spend an extra $10, it is nice to have the grip on the sides with the UVBTS style - but the UVBT gets five stars for optical quality, build quality and price.

    Rated 5 out of 5 by from Low-profile, Lots of Light Transmission I use a UV filter as a protective filter on all of my lenses because it may take the brunt of a drop or bump, but also because it keeps salt water spray, dust, and sand off of the front element of my lens. But I won't just put any UV filter on my lenses, they need to be clear, without color cast or distortion, and cause no vingetting. This filter fits the bill perfectly.

    Rated 5 out of 5 by from BT vs BTS I'm really digging the Chiaro filter line and I have been investing in their top of the lint 99-UVBTS but I wanted to see what the difference between the BTS and BT were all about. Same brass filter ring, same Schott glass, same 99% light transmission...the difference is in the knurling. To be honest, I haven't experienced knurling with filters before and I absolutely love the top and side knurling on the BTS - incredibly easy to grip at an angle to take on/off. The top knurling on this filter is like teeth on the top of the brass ring. This seems to be better suited for stacking another lens on and making sure it won't stick. You can still use the top knurling to get a grip on the filter to remove or put on - but after testing I prefer the top and side knurling the best. Price difference between the BTS vs BT is $5 so why not get the absolute best?

    Rated 5 out of 5 by from Chiaro UV Filter Most of my filters are B+W because I dont want my lens quality compromised.  I needed a new 67mm UV filter and saw the Chiaro.  Had not heard of this brand, so I checked out their web site - its very informative, and I would recommend having a look.  It certainly appears to be a very good filter.  I have noticed no image degradation, and I do comparison shots.  I would certainly buy Chiaro again if I need another UV filter.
