Here’s a fun patent from Canon – a lens that sucks. And I mean this quite literally. This lens incorporates a mini vacuum cleaner that cleans your camera sensor from dust.
Canon patent application 2019-191432 shows this interesting lens design. As we all know, our sensors collect dust particles over time as we change lenses. If there are too large particles, they interfere with your photos. With this patent, Canon wants to solve this problem and let you remove large dust particles without having to remove the lens and clean the sensor.
Basically, this lens has an airflow circuit around the optical elements. It pulls air from the outside, it hits the sensor, and dust gets sucked away and flows out. In other words, this airflow creates a negative pressure around the image sensor. This way dust and other particles don’t stick to the sensor.
If you think you saw this before, that’s because you did. A few years ago, Fujin Mark II was introduced, and it’s a “lens” that’s actually a vacuum cleaner for your sensor. However, from what I can understand, Canon wants to bring the “vacuum cleaner” and the lens together. So it will be like the Fujin Mark II on steroids. If it ever gets produced, though.

Just more evidence that Canon truly does “suck”. This is a horrible idea…you’re just going to suck in more dust particles etc….which will get on the sensor with any that may be on it already and it’s going to fuck up this it’s an actual lens by getting dust and dirt on it. The best way to clean a sensor is send it in to get it cleaned or if you do it yourself, go do it in your bathroom after running your shower as hot as it can go to have a sterile clean environment.
I’d definitely rather go that way, too! :)
I use a sensor cleaning kit I bought at Henry’s Camera and I do my sensor cleaning (when it needs it) in the bathroom with the shower on full heat and steam to make sure the bathroom is dust free and sterile
You can get a similar effect by running the shower on cold, just with the water mist cleaning the air. That way you can turn it off once the air is clean enough, and there is no leftover steam to get into the camera.
yeah, every camera loves a warm, super humid environment with the lens off…
They can be this innovative but can’t give us 4k without a crop?
I had to check the date….its November, not April 1st !! hahaha
It’s gonna really suck lol ?
Yep, I’ll use it. Right after I take it out of the dishwasher. ?. Top rack of course.
Dyson Optics.
Ive used a low powered car lighter vacuum put on just one edge of the back of the lens. Worked great. Had loads of dust from a truck 4×4 weekend of shooting.
What could go wrong?
Isnt that their 100-400mm already? Or is this an automated one? ?
One for female photographers, I think.
It probably sucks.
