I'm just terrified that if I make one wrong move, a hair or a piece of dust could fall in there, and then the camera will be irreparably damaged and I'll never be able to use it again. Fear not, young Padawan. Those of us who regularly use dSLRs can attest that simply having dust or hair fall into your dSLR body will NOT irreparably damage anything, and you ...

Film negatives are only light-sensitive while in the camera, until they are removed and processed. The processing includes a step to "fix" the image so that the negatives will not be further exposed by light. So once processed, film negatives (and slides) can be handled in daylight.

This might sound like a stupid question, but… is it actually “safe” to change the lens on the camera? Is this likely to destroy it? Changing lenses is quite safe for your camera, less so for your wallet. Once you see what your camera can do with different lenses, you'll want to start a small collection. Some lenses, like a typical 50mm f/1.8, are very ...

My advice would be to take your camera everywhere you might potentially take pictures. Take reasonable precautions to avoid shocks. If it gets damaged have it fixed. You could keep the camera in its box for ten years and at the end of that period you'd have a pristine camera that would still be worth nothing. So you might as well use it as much as possible ...

No, there is no danger. Any EM fields outside the microwave are very weak. There is no danger or risk. Microwaves are like visible light waves, except bigger (the "micro" is in comparison to other radio waves). Both are non-ionizing radiation; they don't have the energy to displace electrons in atoms. And, just like visible light, microwave radiation ...

There are reasons why broadcast studios, commercial film/video production studios, commercial photography studios, etc. have strict "no-smoking" policies and have had them for decades before the more recent trend to ban smoking in most public buildings as a public health issue: long term exposure to the byproducts of burning things can be severely damaging ...

With electrolytic capacitors, disuse can cause slower discharge, and longer recycle times, which can be restored by firing and recycling the flash a few times. If you don't use them for a long period, the non-conducting dialectric can break down to the point they will short circuit. Periodically turning it on will charge the conductive plates and this will ...

Weather Sealing is protection of the internal parts of a camera from external influences such as moisture, dust, and humidity. The degree of this weather sealing varies between manufacturers and also within models by each manufacturer. The protection is provided by both rubber sealing with silicon rings and gaskets as well as design considerations such as ...

The camera interior of an SLR camera is not air tight. However condensation is not generally a problem when changing lenses outdoors. Condensation occurs when moving indoors due to a cold glass surface being in contact with warm moist air. When changing lenses outdoors the cold air is dry and so condensation will not form inside the camera. When taking ...

Like previously stated here by others, the shoe on most camera is pretty stable. However, the bottom of the flash is not as strong and you could very easily break it off. There was a co-work of mine at a paper whose whole bottom of the flash broke off just from holding his camera that way. He was fortunate that his D3 and 80-200/2.8 landed on top of a pad ...

China is huge. China is so huge that two cities can seem to be two different countries. This means Chinese do travel to other cities as "tourists" too. I am from Hong Kong, so I am a Chinese too. So being in China I think I can offer some good insight. Fact is, Chinese who travel to other cities as tourists are often the more wealthy ones, and enjoy a so ...

Most DLSRs with "silent" or "quiet" shutter modes don't change the speed at which the shutter is operated at all. The transit time each curtain takes to traverse the height of the sensor is constant regardless of the exposure time (shutter speed) selected or if a "quiet" mode is selected. Exposure time is determined by the time difference between the ...

The filter doesn't protect against dust getting "into" the lens, it just protects the front element. So the arguments for a filter are equally valid for zooms and primes. Personally I don't use them, as they have a negative impact on image quality. Always keeping you lens hood on is another way to protect the front element. Also, I recently damaged my lens ...

*First I'll say that this is mostly preference and you should take all answers into consideration. Regardless, a proper bag should be used. A proper bag has at least 1/4" padding on the outside and separation for all lenses. The outside should have rigid panels to prevent flexing and distribute force from bumps. It should have strong zippers to prevent ...

The hood protects the lens of physical impact from knock and obstacles. It also reduces flare and keeps image quality to what the lens is capable of. A UV filter protects against flying dangers such as sand, salt and other elements. While doing so a UV filter is detrimental to image quality as it adds additional reflections from another glass element in the ...

I wouldn't be concerned much about the camera body; there isn't really anything in it that would be very sensitive to vibrations. The only mechanical parts are the shutter and mirror, and both are in a safe postion when the camera is switched off. Lenses are a different matter: individual lens elements can and do become decentered, which can result in ...

A DSLR doesn't have a cellular or network connection, so there would be no way to have it report it's position. Some DSLRs include the serial number of the camera body in the EXIF meta data on an image, so if someone posted an image online with that meta data intact, there is a chance it might get indexed by something, but that's a long shot at best. It's ...

The best method I've found for general situations is: Turn your back to the wind (if it's raining or extremely windy you should seek additional shelter). Use a neck strap so you can let go of the camera. Select the next lens, remove the back cap and pocket it (choose a clean pocket). With the camera still hanging around your neck, with your free hand, press ...

The safest position for your SLR is in your bank's safety deposit box. Once you decide you want to take pictures, you must accept some non-zero risk of damage to your camera. Camera in bag with lens facing up: - Harder/slower to remove camera from bag. - If bag hits ground, you must ship the body off to repair the screen Camera in bag with lens facing ...

May I hold the DSLR in part by the hotshoe flash? Yes, you may. Your attached photo perfectly demonstrates that you can hold the camera in this way. Will so holding my camera result in any unpleasant consequences? More than likely it will. In most cases the weakest link will be the part of the flash that connects to the camera's hot shoe. It's designed ...

Jay Meisel maintains that it is hard to make good images if you don't take your camera along. So which do you optimize for? Longer lasting equipment you don't use or a possibly shortened lifespan of equipment you use regularly? Here is a quote from one of Jay's students: I haven’t left the house once without a camera and realize it’s impossible to be a ...

A filter offers more protection than a hood alone. I have had a filter save a lens from certain severe damage when a lens hood failed to do so. How much UV filters affects image quality is a much debated subject. I have added a comment on this at the end - mainly pointing to some objective measurements. Here are the test results for the best UV filter in ...

Hallo I have found reverse lens protectors for Canon and Nikon on a german website. The best thing about these are you only have to buy one, and you can use it on all your lenses. you can buy them here: Traumflieger reverse lens protective filter (Canon) Traumflieger reverse lens protective filter (Nikon) The protection ring is attached to the rear of ...

Nikon is puposefully vague about weather sealing. They say resistant to casual humidity in the manual. It doesn't sound likr much but I used their D3S in the rain without problems. The D7000 is one level below but I would expect it to work in the rain and snow. I have a Pentax K-5 and K-7 which the same class of camera and have rinsed both several time ...

The ES-52 works a little differently than most lens hoods we are accustomed to seeing. Instead of blocking off-axis light by extending a cylinder or cone perpendicular to the image plane and centered around the optical axis, The ES-52 blocks extraneous light by placing a smaller circular opening parallel to the image plane. Due to the difference in design, ...

You are confusing weatherproof and freezeproof. Some digital cameras are weatherproof but not freezeproof, although all current freezeproof cameras are weatherproof. Weatherproof generally means that the camera can be splashed with water from any direction without water entering the camera. There are standards to measure this but most camera makers are ...

In some cases, using a hotshoe cover prevents the internal flash from popping up. Many Canon models had (currently have? I don't know) a microswitch in the hotshoe rails, that sensed the presence of a flash. Of course, the hotshoe cover's geometry looks just like the foot of a flash, so the camera thought an external flash was attached, and would not pop up ...

No. It does not. I own currently 7 digital cameras and I have used some after being unused for over two years without any problems. Even the Lithium-Ion battery still had some charge after that period. Those who use AAs will note that rechargeable NiMh ones lose their charge after a month or two unless they are Imedion or Eneloop (low-self-discharge). ...
