All Used Cameras: Page 2

What should I look for when buying used cameras and lenses?

If you’re shopping on a budget, then buying used camera gear is a great idea.

Modern digital cameras are updated on a regular basis, so the used market is full of cameras looking for a new home.

Used cameras are a great way to upgrade your gear without breaking the bank.

Below are some pointers to make sure you get the best bang for your buck when buying used gear.

That way, you can update your cameras, lenses, and accessories for a fraction of the original price!

Here's a little guide for buying used equipment and basically the checklist that we use ourselves when checking in trade-ins. 

Remember, for a hassle free purchase, buying from a shop gives you the peace of mind that you're buying a fully checked and guaranteed product. 

What should I look for when buying used cameras?

Cameras are complex machines, so there are a few key indicators to look for when shopping for a second hand body.

What does the shutter count on a camera mean?

The shutter count of a camera is simply the number of times the shutter has been fired in its lifetime.

(The shutter count is also known as the number of shutter actuations.)

Generally, the shutter count will give you a great indication of the amount of use a camera has seen, similar to checking the mileage on a car. Cameras are rated for shutter durability, with enthusiast models often rated around the 150,000-shot mark, and professional models rated at 300,000 shots or higher.

When browsing, low shutter counts often indicate less heavily-used items. Fewer than 10,000 shots on a camera that is 2-5 years old is very low, with the normal amount being around 30,000-50,000.

If a camera has a very high count of 100,000 or more, it’s probably best avoided, especially because this number will also give you a little insight into the owner’s use of the camera. Higher-count cameras may have seen professional use (and a harder life), while lower counts indicate casual consumer use.

What camera checks should I do when buying a used camera?

When looking at a used camera, there are a few things you can check to get a better understanding of its condition.

First, remove the body cap and inspect the inside of the camera around the mirror, focusing screen, and lens contacts.

Look for any signs of damage, oil, or gunk that has collected in these areas.

Inspect inside the camera, paying special attention to the mirror and focusing screen; look for any sign of oil or residue.

Oil can indicate that the mechanisms of the internal parts are not functioning correctly, sometimes due to the camera being bumped or dropped. Look for any oil around the sides of the internal section. A small flashlight can be a big help here.

Remember to hold the camera face-down as much as possible to reduce the risk of contamination from dust and dirt.

When inspecting a camera, try to hold it face down.

If you have a lens on hand, it’s worth taking a test shot to look for any issues with the sensor.

Set the camera to f/16 to f/22, point it at a bright subject (a white wall or the sky), and shoot a frame. Play the image back and zoom in on the LCD screen to look for any marks and scratches.

Dust spots are not a huge problem, as a simple sensor clean can take care of them. But lines can be evidence of a scratch on the sensor (which means that the camera is best avoided).

What general wear and tear is ok when buying a used camera?

Of course, it’s also important to look for any external signs of damage. Small scratches, scuffs, and marks should be expected, but heavy blemishes can indicate that the camera has been dropped. Rubber grips often start to come off with heavy use, but these can be replaced at a low cost.

Outside grips often become worn and unglued. As long as there are no signs of a drop, these are a simple and cheap fix.

Remove any protective screens or filters to look at the true body and lens in order to assess the damage.

Look externally for any signs of bumps and scrapes. Often, cameras will have a few marks, but major dents may be evidence that the camera has been dropped.

What should I look for when buying used lenses?

Camera lenses are expensive, so secondhand options are a great alternative to buying new.

Once again, however, there are a few things to look for when making a purchase.

What are lens blemishes?

When inspecting a lens, you’ll want to check both the external and internal optics.

Externally, look for any scratches or chips on the glass. Tilting the lens toward the light can help you make sure the optics are in great condition.

Often, lenses will show signs of wear on their focus or zoom ring and the external barrel. Simple rubbing is normal and isn’t usually a concern.

Moving on, inspect internally for dust and mould. Shine a small light inside the lens and look for any particles. Most lenses will have small dust spots, but look for any large patches or seemingly smeared areas, as these will indicate whether the lens has any fogging or other internal issues.

Look through the optics to ensure they are clear of dust and mould.

Heavy dust and mould in a lens are to be avoided. The hundreds of particles inside this lens offer a perfect example of what not to buy.

Using a small flashlight, inspect inside the lens, paying particular attention to the aperture blades. Any evidence of oil may indicate the lens is functioning less than perfectly.

How do I check the aperture blades of a lens?

On the rear of the lens, you’ll find a small lever that you can push to open the aperture blades.

Do this, and check if the blades are snappy and without any stickiness that could be a sign of collected oil.

Using the lever, you can manually operate the aperture for a better sense of the lens’s functionality.

Check that the aperture blades are snappy when they open and close.

Look through the lens with the iris fully open, once again checking for any particles or oil spots.

Open up the lens’s aperture to aid inspection.

How do I check the sharpness of a lens?

Check the lens sharpness using a test chart. These patterned charts are easy to find online, and they can be stuck on a wall and used to quickly evaluate a lens.

Mount the lens on a camera, then put the camera on a tripod. Focus on the test chart, then fire the camera using a remote release or the self-timer (to make sure you don’t create any camera shake).

Check the shots on your camera LCD (or, if you can, on the computer). Zoom into 100% to be sure of focus. Of course, some cameras and lenses will need fine in-camera adjustments for perfection, but any wildly unsharp tests may indicate a lens has been dropped or is out of alignment.

It’s also a good idea to test the full aperture range and look for sharpness from edge to edge. Even at f/2.8, the center of your test image should be relatively sharp.

Additionally, it’s a good idea to look for any external marks or blemishes when performing these tests, turning the focus and zoom rings to check for any stickiness or grating sounds.

With those checks done, you’ll have a good indication of whether the lens is worth purchasing.
