well the concept is good... but in general, this tutorial is giving bad advice. The golden rule for sensor cleaning is... DO NOT apply air pumps or any other kind of strong air blasts into the mirror box, you run a very high risk of hitting the lubricating compounds from the mirror mechanism and spraying it all over the sensor!!!!
You should apply a very low pressure puff of air, just enough to float loose dust out of the camera... then use a sensor swab to carefully remove dust from the sensor.
I like it. as filtered air goes in, dust and air flows out of the camera. Zoom lenses are the worst, drawing in dust around the outer movable sleeve, possibly migrating into the camera. I found a great way to check for dust, take the highest resolution image you can with the highest Fstop available. of the a clear featureless blue sky, upload it to the PC, then zoom it 100%, then scroll around on it, you'll find any dust or grease. Works quite nicely for a quick check.
$30? Not worth it for a gimmicky filter. You'll be blowing around dust into your camera either way from the surrounding atmosphere, so there really is no reason for a filter. The best bet is to find a place with the least amount of dust possible to clean your sensor.
hey please reply fast have a canon t3i and in the viewfinder the little pice dioptric i think i see a small dot y have spend 80 dollars on cleaning kits for sensors but y went to canon and they told me they don´t know what to do but thy can do nothing about it and i have clean everything amd lens to i don´t have more lenses just a 18-135 kit lens and i have cleand everything and still that point there :( please help
You can not touch the sensor even if you wanted to all you clean is the low pass filter. Scaremongering is made by all who want to sell you expensive cleaning kits
Yeah but the filter side isnt the only side pulling in air... since the filter is blocking some of the flow.... the nozzle will also suck in contaminated air.
Don't worry about cleaning the filter. The Hepa Jet II uses a respirator filter meant to be used for hours at a time. Thus, on a hand blower, it is highly unlikely you will ever need to replace the filter under normal use.
I like the design...yes cleaner air to knock the "loose" dust from the sensor; however, the problem that most often arises is when little specs of dust accumulate on the sensor and the sensor is subject to a decent temperature delta where condensation can occur. When this event happens the dust specs then become specs of mud (well sort-of) that when dries adheres to the sensor making it cleanable "only" via the "web" swab method.
By using the Hepa Jet II instead of conventional blowers, you will introduce less dust and humidity, thus reducing the number of times you will need to perform a wet swab method. The Hepa jet II removes humidity as well as dust so the incident of fused dust spec due to condensation is reduced.
I own this Hepa Jet but I'm not completely convinced : what about the dust which is throw out from the chamber to the prism (particularly with this force on the demo) ?
To be extra cautious, you can blow the dust off the chamber first and then open the mirror to blow dust off the sensor. In any event, it is superior to using an unfiltered blower.
