Dust
Jan 28, 2020 06:12:27 #
A little bit of dust inside the lens will not have any effect on the images. A lot of dust merits cleaning but since I never had that problem I cannot make any comments regarding the price a technician could charge.

Any point on an image is derived from a point in the subject and passes through points all across a lens. A speck of dust interferes with a minute amount of those points. The interference is minimal.

I looked in this subject in the "Search" box but did not find anything yet that treated with this problem. I have an opportunity to buy a lens I have been seeking and the seller says there is a little dust in it and I am curious as to how dust impacts an image.
The link below gives some outstanding examples of dust and other insults that a lens may suffer through and still perform well.

It is an older link found here on the UHH site and could either affect or affect your outlook, grin.
Starting out, be sure to read the small print and scroll down for various examples regarding your question.
At any rate thanks for letting us show our collective stuff, both good and bad.

Generally speaking, a small amount of dust in the lens does not effect the final image. I have had several old Minolta AF lenses that I use on my current Sony's with varying amounts of dust inside the lens, I have never noticed any difference in image quality when compared to newer Sony dust free lenses.

This usage of "impact" is acceptable. Please take note of the definition under
"transitive verb." (If you don't know who Noah Webster is, I do suggest you look it up.)

Getting dust in the lens is quite normal. Lenses are not air tight. They have to breathe. Every lens I've had had dust and it never affected the image at all.

A few specks of dust in a lens will not affect overall quality. A lot of dust, or MOLD, or FUNGUS, will cause problems, reducing contrast and sharpness.
If you're buying the lens from a seller with a money-back guarantee, you can check the lens visually and with a camera test to see whether it's worth keeping...

WOW!!! That was the second rude and unnecessary comment I have heard in two days. I am someone who occasionally corrects grammar but I always try to do it with a smile and not be insulting about it. You however are way beyond the norm in this case with regard to rude and insulting behavior.
Actually I think the OP can use the word, impact, in his sentence because dust in the lens may impact the quality of the photograph.
By the way, when you use quotation marks there should be a comma before and after the quoted speech. Don't thank me now. Save it for the next time you make a fool of yourself when calling someone else a grammatical moron.

Here is an experiment I encourage my students to try: tear a small piece, say 1/4 inch across, from the sticky part of a post-it note. Stick it on the front of your lens. Take a picture. Notice, no effect. Or impact. ;-)

The owner of Lensrentals has a podcast and I had chance to listen to one on this very subject yesterday. As you point out, the fee for cleaning is somewhat dependent on the lens design. Some manufacturers actually consider ease of disassembly and maintenance. Others not so much. Additionally, modular design has become more and more popular with some lens, so it may become more difficult to access components for repair or cleaning, not mention the need to replace assemblies rather than individual parts. They also discussed turnaround for a few manufacturers, which is largely dependent on lens design, number of authorized repair centers, and part availability. From Lensrentals, Canon and Sony received the highest marks and strive for less than a two week turnaround. Nikon 2-3 times as long, and a lower volume manufacturer like Leica, who knows how long, especially a repair that requires parts not in stock.

It doesn't make much of a difference.
