Does the dust on the clear aperture of the SLR lens affect the use?

SLR lenses in normal use have different degrees of ash ingres.

Even if the inside of the lens is not dusted, the surface may be stained.

It's inevitable.

Generally speaking, when shooting at full aperture, the effect of dust is negligible because the aperture is relatively large.

However, when shooting with a small aperture, dust will appear, and small patches of dark shadow ...... can be seen on the **

At this point, it's time to take steps to clean up the dust.

Dust on the surface of the lens can be blown off with an air blower.

However, for the dust inside the lens, there is no way for the average user to clean up the ......It can only be dealt with after sale. This is a more troublesome thing.

So for many photography players, the lens is in the dust, and the ...... is ignored directlyAs long as it doesn't have much impact on the effect of the film, ignore it......aqui te amo。

A small amount of small particles of dust has a negligible effect on the imaging effect! If the amount is large, it is best to use a professional lens cleaning tool and cleaning solution to clean. If there are stubborn large particles of dust, you can spray the cleaning solution and wrap the lens with plastic wrap after a while, and then clean it with lens polish.

Do not wipe vigorously.

There is no effect on image quality, but it will diminish the light, reduce the shutter speed or be forced to use a wide aperture, but the effect will be weak.

What to do if dust gets into the eyepiece of the DSLR camera:

1. First of all, make sure that the shadow does not affect the imaging, and if it does not affect it, try not to wipe it. When there is an unknown gray spot, it should be cleaned up.

2. If you really want to wipe it, you can determine the location of the ash, it may not be on the lens, maybe on the CCD or on the mirror or viewfinder. If it's really just gray on the lens, take the lens down, twist the zoom ring to the maximum, blow it with an air blower and then wipe the front and back with a lens cloth, be sure to use a special non-lint wiping cloth, otherwise it is better not to wipe it, and never use lens paper. Blow it again after wiping.

3. The lens is a very sophisticated digital product, and it is generally not possible to clean it by itself, unless it is a professional maintenance specialist. If it does not affect the photographic image, it can be cleaned without cleaning. If you must clean, you can go to the designated maintenance station for free cleaning, and you must correct it after dismantling the lens for cleaning, if the correction is not good, it is very likely that you will not be in focus.

4. If the sand is not gray, it will be very troublesome, not to mention the impact on the image quality, if the focus ring is blocked for a long time, once the zoom ring is broken, it will be very expensive to repair it. It's best to take it to a regular store and let someone handle it.

Of course, you'll have to blow it clean with a balloon. Balloons can be purchased at tool shops that repair clocks and watches.

It doesn't matter if the film doesn't affect it, but it's best to clean it up, first make sure it's not on the viewfinder, wipe the viewfinder clean and it's on the reflector, take off the lens flashlight and you should be able to see where the dust is, blow it with a rubber blow first, if it still doesn't work, gently brush it off with a soft brush.

Clean it with a jelly pen and it works great!

It's normal to have ash inside the lens, please ignore it. OCD has to be cleaned up estimated, and in cases that do not involve disassembling the lens set you can clean it yourself, ready with clocks, tic-tac-toe wrenches and screw fluid, lens paper and lens cleaning fluid. Finally, it is necessary to note that there is a risk in removing the lens, so you need to be cautious.
