Unlike a mirrored camera, there is little likelihood of the sensing system in a mirrorless camera suffering a catastrophic failure so it is really up to your "taste" to determine when a sensor is too old. The primary causes of degradation to a CMOS sensor array are heat, dye neutralization and cosmic rays. Thermal Degradation Normally thermal damage is so ...

The residue left behind when your fingers touch the glass of your lens contains several organic and chemical compounds. Normal skin oil has a pH level of around 4 to 5.5, which is mildly acidic. The longer it is allowed to be in contact with materials reactive with acids, the more reaction will take place. And yes, acid will eat through the coatings on ...

When it is dirty, no more or less often than that. If you can't see any obvious dirt or fingerprints then don't touch the lens surface at all with anything. Every time you touch a lens element it's an opportunity for damage so it's not really worth it unless the dirt is visible in your output.

So, the common idea is that the UV filter helps to protect the lens element from damage. Stores love to push that concept, a lot, and I think it stems from trying to actually get rid of them in the digital age when it didn't really need them. They've now managed to create a sustained market for UV filters despite the fact the UV part of it is meaningless. ...

I would suggest taking your camera into a professional for camera cleaning. Who knows how serious the issue is - plus, I mean....termites...are you sure it isn't some other bug? Either way, I definitely wouldn't use any harsh chemicals or substances on my camera - I would rather spend a little money not to ruin such an expensive device...hence the advice to ...

Nikon cameras and lenses are covered by a 1 year warranty. Lenses have a 4 year extension of that warranty. If you have an issue under warranty it doesn't matter if it's in the 1st year or the 5th, the coverage will be the same. If a lens is repaired under warranty, there will be no charge for the repair - you will have to cover the cost of shipping the ...

It's not really a big deal for two reasons on both sides of the equation. On the one hand, dust on the lens is positioned at a place where it will have negligible impact on the final image. That's because they'll be completely out of focus, and are so tiny to begin with Generally, it's not worth worrying about. On the other hand, lens glass is very hard, ...

The Lens Pen is my favorite first line of lens cleaning. This is a pen-shaped tool with a very light non-abrasive brush on one side and a powdered cleaning agent on the other. Always brush first to remove an particles from the lens surface. If there are marks stuck to the lens then I use the cleaning side to remove it. This is very effective and minimizes ...

It sounds like keeping this printer alive is a burden that you don't even want to put on the shoulders of somebody else. Instead, use the situation to your advantage and the person taking care of your printer. print 1 test page per week Why would you want to print a test page?

The sensor on a digital camera is a solid-state device, and while theoretically degradation is possible, in practice, they last basically forever. Don't worry about it. On the other hand, the mechanical shutter on these cameras does have a finite life, probably normally in the range of 100,000 actuations (although it's not typical for camera makers to give ...

Ensure that the padding is still in good condition and positioned to stop the camera / lens from moving around to much. To clean the outside of the bag a soft brush and some water should do the trick. As for the inside depending on the material type, a damp cloth or a can of compressed air should clear out any dust. If you have a small attachment you ...

Here are answers for your questions based on my YN-465 and all the research I did before getting it: What are most common issues that would require repair of a speedlite? The number one cause of speedlight damage is dropping it - if you drop it and you are unlucky it will break. The "professional" series (models 5xx) are supposedly much better at ...

Clean your lens when it needs it. Not any more complicated than that. The goal is to eliminate the chance that something on the lens will impact your photo. Due to how close the dust is to the lens, and the fact that you are focusing far from the dust, you will be surprised at how much dust makes very little to no impact. If you are concerned about ...

Since neck straps are more or less disposable most people don't mind if they break. Knock-offs can be had on ebay for a few dollars. The stock cannon ones last ages (I've had one for more than 5 years now and no issue aside from cosmetics). If you want to go the way of a 3rd party neck strap i reccomend the unfortunately named 'R-strap' from black-rapid. ...

Even if the front element gets a few scratches on it, the effect on image quality is negligible. This is because light from each part of the scene strikes every part of the front element (unless something is causing vignetting). Although hard to believe, it really takes a LOT of damage for image quality to be noticeably degraded. Check out these pictures ...

No. It's fine; I can't imagine why there might be a problem. Automatic sensor cleaning generally works by shaking the sensor a small amount at high frequency. This doesn't get anywhere near the lens (at least, not more than the sensor already is). I guess it's mildly possible that some dust might end up transmitted to the rear element of the lens, but that's ...

Dust in a DSLR generally ends up on top of a thin layer of glass(like) above the sensor, usually an anti-alias filter. Even on cameras without AA filters there is still usually a layer of glass (or similar) there. This means the dust is slightly above the sensor. When you expose with a lens set to a high (small) aperture, this near-point-source casts a ...

UV light will kill the fungus, so all you need to do is let the lens be exposed to sunlight for a few days. Be sure to remove any UV filter you might have attached to the front of the lens. Unfortunately, killing the fungus is not removing it. If it does not affect image quality, then that might not be a short-term concern. But you'll likely need to ...

The Nikon scanners do not require regular maintenance. They are however quite prone to dirt and dust. Your best bet keeping the scanner running problem free for a long time is to store it in a clean place (wrapped in a cover) when not in use. Some units are also starting to show signs of age and may e.g. have problems with the lubrication drying out. They ...

The problem is, any clear piece of plastic or glass that is not FLAT to an extremely precise standard is going to act as a lens or prism of some sort, adding distortions and aberrations. Using a polishing wheel is most certainly not going to help making a surface perfectly flat. In addition, if the surface is plastic, most abrasive compounds you would use ...

When you use a high f stop, the light that hits the sensor is highly collimated — the light rays are mostly parallel. The dust isn't actually directly in contact with the sensor; there's a thin filter in front of the actual CMOS or CCD chip, so the spots you see are actually the shadow. When the aperture is small and the light rays mostly parallel, this ...

Force some talcum powder (or better yet, powdered graphite) into the friction surfaces of the head. This works like little ball bearings for the plastic-on-plastic rubbing of a cheap tripod head. Don't use oil, it just makes it worse. I have a $25 Amazon Basics tripod, and this made a big improvement. I drilled a little hole in the panning head to force ...

Ink dries. Small air/ink channels can clog when ink dries. Printer dots (and therefore nozzles) are really small. That's pretty much the reasoning behind having to constantly use an inkjet printer to avoid having the heads clog. You need to keep the ink flowing. You can have someone visit your printer and run a print every week or so. It could be that it ...

The coating was probably already damaged by the fungus, not the alcohol. Though you should consider using a lower concentration (70-90%) like a normal person. PetaPixel: How to Remove Fungus from a Lens describes removing fungus by soaking the affected elements in an aqueous solution containing hydrogen peroxide and ammonia. After the fungus has been ...

As a beginner, you should assume that the professional shop you sent the camera to did their job. Verify that whatever problem you sent it in for is fixed, and then carry on shooting as normal. Because people are more likely to complain about problems then report "everything is fine" on the internet, you may have gotten the impression that repair jobs ...

If it’s specifically undergone sensor cleaning, then test this by photographing a white wall at f/22. Look for dust. Is it better than before you sent it in? If yes, carry on. If no, contact your repair shop for a redo.

A factor not yet mentioned is changing expectations. When you buy a new camera you get the newest thing on the market: higher resolution sensor, better low light performance, better autofocus system, faster processor, and longer battery life than your previous camera. Over years of use your camera will experience wear and tear that might have a small impact ...

A standard plastic lens cover or cap is simply used to protect against scratches, impact, or in the field weather conditions. It is not for any type of seal. For strictly standard plastic lens covers I would say that leaving them on or off is not going to alter the storage potential. This question could be a bit different if you are talking about metal lens ...

In terms of making sure your camera is safe - make sure that when choosing a bag, the camera and any other components you're likely to be carrying fit snugly inside. It's better if it's a tiny bit too tight to begin with, as padding compacts over time. If your bag is made of fabric and you're outdoors a lot, consider going to a hiking/outdoors store and ...
