Hoya EVO Antistatic Filters Help Keep Dust Off Your Glass and Out of Your Shots

hoyaevo

Sick of wiping and blowing dust off your lens filter? Check out Hoya’s new line of EVO Antistatic lens filters, which actively repel dust particles to keep them from sticking to the glass.

The image above is a side-by-side comparison showing what happens when an EVO filter and an ordinary filter are placed into a container with static-y packing materials. The charged pieces stick onto the lens filter on the right, but ignore the EVO filter on the left.

Each filter features a new antistatic coating developed by Hoya engineers that acts as a “force field” around the filter to keep dust from clinging. For photographers working in dusty and dirty environments, these filters should greatly cut down on how often you need to wipe down the front of your lenses.

In addition to being static-resistant, the filters are also water repellant (drops bead up on the surface instead of clinging), stain resistant, scratch resistant, and can be easily wiped of smudges and fingerprints.

Hoya also claims that the filters have an excellent 99.8% light transmission rate, which helps make the filter “invisible” to your final shots.

The EVO line is available in Protector, UV, and Circular Polarizer models in sizes ranging from 37mm to 82mm. They’re available through various photo gear retailers starting at $28 (for a 49mm UV filter).

    They need this for sensors ;)

    . I agree that Marjorie `s story is exceptional, I just purchased a new
    Infiniti when I got my cheque for $7677 this-past/month an would you believe
    10/k lass month . this is certainly the most comfortable work Ive ever had .
    I began this five months/ago and almost immediately made myself more than
    $81, per hour . go right here

    Hmm, I’m SURE I saw this posted about a year ago. Well anyway, I think if the surface is superhydrophobic, that’s by far the most radical feature, assuming it’s good enough to then shoot in the rain/spray/snow without constantly wiping the lens!

  • BuckCash

    Show a shot without dust, then the same shot with dust, so we can see what a big difference it makes. Be sure to show how much dust it takes to make a difference.

  • OtterMatt

    Seems pretty obvious to me, especially for a sub-$30 filter. Less dust is better than more dust. Dust can scratch your lens when you wipe it if you’re unlucky. Less wiping is better than more wiping.
    Go ahead and post some test shots of your own to see how much dust makes a difference if you need to.

  • BuckCash

    I did those kinds of tests for about 30 years, and my experience led me to stop using filters altogether, other than ND and Polarized. They cause more trouble than they prevent, leading to unwanted ghosting, reflections, and other such artifacts. They put an unnecessary piece of glass between my expensive glass and my subjects.

    Meanwhile, simple dust doesn’t show up in photos or become a real issue unless it’s in VERY large amounts that are caked on like mud.

    As for the potential of scratches, if you don’t know how to properly clean your lenses so that you don’t’ scratch them all up, then you have much bigger issues you should be working on. The lens on my very first SLR harkens back to 1963, never wore a filter, and isn’t scratched up at all, so it’s not something I buy into when people warn me about it.

  • 1000nunsandorphans

    Agreed! I wish more people understood this. Flat glass put in front of a sophisticated computer designed lens can only degrade the image, with the exception of a polarizer. And I would like for anyone to tell me what lens out there can actually focus on dust particles a few millimeters in front of the front element. Also, front elements are usually (always) made of very hard glass. Cleaning it with ‘dust’ on it will not harm the lens. Decades old lenses which have undoubtedly been cleaned dozens (hundreds) of times, are not scratched. This is just a marketing scheme. Go out there and take photographs. Stop worrying about everything they tell you to worry about.

  • Kyle Sanders

    As you say, dust is not a big deal unless it’s large and you are shooting at F/22+.

    Scratches, on the other hand, are something I am more fearful about from impacts and damage rather than cleaning. If you are in a controlled environment, it’s less of a concern – but more of a legitimate consideration if you are doing something involving risk.

    Ghosting is another matter altogether – ditch the filter for long exposures!

  • Kelly Padgett

    You saw something about this a year sure. I use to work in a camera shop, and saw these when the rep was introducing them to us.

  • OtterMatt

    Interesting. I’ll admit, I use a clear UV filter at pretty much all times, not because I’m worried about dust, but because I’m more worried about impacts to the lens than anything else. I’d still like to see a photo as to what kind of dust finally starts to make a difference, though, even if only for my own knowledge.

  • Pickle

    I have never seen the outer limit of a lens get scratched during cleaning. That is a thick hunk of glass with fancy coatings. What I have seen many times is lens flaring and degradation of an image because someone put a filter in front of their precious kit lens to prevent the boogyman scratch that doesn’t exist. using a filter to prevent dust when there is no imminent danger (in the way of a beach or one of those stupid color powder parties) is even more dumb.

  • Pickle

    If you really want to do this, rub some fabric softner on your current filter and be done with it. Why would you want a filter in the first place however? You paid $2000 to get the best f/2.8 lens in the market with the fanciest glass and coating so you can get every bit of image quality you can get out of it on your fancy camera with the latest sensor that can get every pixel of quality, and you’re going to put a $30 filter over it and get flares? And for what? to prevent dust that MIGHT fall on the lens?

    It has been established that filters don’t protect lenses in falls and can even end up damaging the lens more so that ain’t it. It’s just a way for the dealer to make a little more money. Call it rust-proofing for the ignorant camera buyer.

  • Claude

    I am definitely more afraid about shattered filter silvers in front of my lens then about my hardcore made glass. My lens hood is my bodyguard. And that’s it. Btw – I think its kind of meditation to clean my gear. So, no I don’t put a 28 $ piece of glass in front of my x-K lens.

  • OtterMatt

    okay we get it. but before you talk down to us trying to care for kit lenses, you might remember that for most of us, replacing even a kit lens would be a financial stretch that can’t really be justified. And if you can tell image degradation from a UV filter on sight alone, then your eyes are orders of magnitude better than mine.

  • Pickle

    You’re not getting it. The $100 kit lens still has real lens glass on it that won’t get scratched unless you try to scratch it. You put a $30 filter on a $100 glass, you’re already spending 30% of that lens to protect it. Save that money in the bank and then use it to upgrade to an f/2.8 Sigma zoom in a year.

  • Kaybee

    I’ve been wanting something like this. Very soon, we’ll have the entire lens made of such technology.

    Start working at home with Google! It’s by-far the best job I’ve had. Last Wednesday I got a brand new BMW since getting a check for $6474 this – 4 weeks past. I began this 8-months ago and immediately was bringing home at least $77 per hour. I work through this link, go to tech tab for work detail

    Pickle, sir, there are other types of filters out there ya know. Not just the “protect my front element” type filters.

    e.g. Polarizers and ND filters

    I agree with you for the Skylight, UV, etc. versions. After doing some personal testing, off they came, as they did not work for me. Too many reflections and ghosting.

    Some L lenses specifically state that they’re only weather sealed with a filter on. Good enough reason for me.
