canon 5d manual


The DSLR (digital SLR) now represent the bulk of the fleet of SLR on the market. If the advent of digital technology brings many advantages, there are still some drawbacks that all brands have not yet resolved: the cleaning of the sensors because of those pesky dust!

Only Olympus had from the beginning, used a cleaning system integrated with its devices. The others follow ... more timidly than two years! However, the problem remains on many devices, and the canon Canon 5D I use, is just as sensitive to this that his "little brothers" to APS-C sensors. Here's one way (among others) to clean the digital sensor safe.
 
 
 



I of course accept any responsibility for the implementation of the advice given here and their consequences in case of false manipulation: does it work in my carefree, each taking its own responsibilities!
Marketed cleaning solutions

Currently, there are many solutions - more or less effective elsewhere! I refer to some "mini-vacuum cleaners" - sold on the market. For most, it takes at a minimum investment € 70 ... when we should not buy the "refills" (pec pads and other accessories of the kind!) Just as expensive!

Reluctant to invest that much in cleaning materials, and especially not really "hot" to put on my Eclipse fluid sensor (I always hated my tracks by tile !!!), I had to find an easy, easy, knowing that by doing minimal attention, only a handful of dust is likely to come to stick by static electricity (grease stains can not seem to me personally, as it does not change its objectives by cooking butter!)

This solution is called an ionizer!
Why an ionizer?

An ionizer is a device that allows you to send one ion flux to be extremely simple, which neutralizes static electricity "loaded" into an object. The goal, as part of what interests us, is precisely to relieve the sensor (or rather the filter which protects) the static holding our little dust, the better to suck then!

I will not go on making such a device (which can be found on the market in accessories hifi, but sometimes prohibitive tariffs, so that we can make one yourself very easily from ... a gas lighter piezoelectric! see a design method in detail here - the final cost: by counting the purchase of a gas lighter low-end of a soldering iron and a coil of tin, € 12!)
 
There is no risk to use an ionizer on a DSLR sensor is a process used in electronics laboratories routinely.

Demonstration in pictures

Nothing is more convincing as a demonstration (guaranteed without special effects! Please excuse the quality of the images, they were made with the Kodak DC7220's son!) First, the necessary equipment:
Materials required for cleaning the sensor
 
 * Your case (by my Canon  5D) with the manual if you do not know how to position it as "clean sensor"
 * Your ionizer (my lovely gas lighter blue as amended)
 * A medical swab (without fibers and can be found in pharmacies)
 * A small flashlight to see what you are doing
 * A vacuum cleaner (a Rowenta 1500W about me)

It is first necessary to "test" the sensor. For this traditional approach: we photograph a flat, light-colored uniform (ceiling?) By closing the aperture (f/11 at least I personally ... "farm" at the smallest aperture that I am supposed to use: no need close to f/32!) and then we look at the cleaning required ... ;-)

Step 1: Position the camera mode "sensor cleaning"
The EOS, it passes through the device menu, simply:
Menu to access the Canon EOS sensor cleaning
OK, then remove the lens






It is valid, then the act of removing the lens in place unlocks the mirror (if none, the unit will direct cleaning mode) ask the housing up and not touch it!

Step 2: "ionize" the first time the sensor
For this, we will use our super ionizer, in action, however slowly (to avoid a possible accident which would generate an electric arc! You never know ...):
Turn gently ionizer front of the sensor

The ideal distance is about 8/10cm film ... Action Plan the ionizer many times.
Ideal distance: about 8/10cm plan film

Step 3 (optional): Move the swab
This step is NO SUPPORT (it should only scratched the surface) and is especially useful in the corners, if your sensor is very dirty. It is intended to eventually "take off" the biggest dust recalcitrant. We preferred to use cotton swabs medical, non-fibrous (buy at pharmacies). The use of a specific solution can help, dry cleaning is not recommended for contact with a lot ;-)
If necessary, gently pass a medical swab on the sensor

NB: Since I have my EOS 5D, I've never gone through this stage, I want to clarify because I do not need.

Step 4 (optional): iron the ionizer
Back manipulation in step 2, only if you went through step 3.

Step 5: vacuum chamber with a vacuum cleaner
To do this, position the tip about ten inches from the film plane, with the minimum power vacuum (this is not to pull an item from the machine!)

Aspirate the entrance to the room minimum power without getting too close alternative: you can more safely use a suction bulb (such as fly-baby, found in pharmacies) to replace the vacuum cleaner, traveling for example. Moreover, too much air can cause depression deposition of dust suspended in the air, carried by the "current" air caused.

That's it! That's it! The result is rather convincing, here's more:
