When you’re buying a camera lens secondhand, there’s a lot to keep in mind. Lenses are expensive and you’ll want to make sure that you’re getting a good deal. Luckily, they’re easy to inspect and there are a few key things you should always look for.
Look for Scratches and Dents
The first thing to do is examine the exterior of the lens. A few dings and scratches are normal, but if there are lots of them it could be an indicator that the lens was dropped or handled roughly. You should also check for fungus inside the lens. This isn’t something that can be easily repaired and should be a deal breaker if you see it.
While you’re doing this, shine a light through the lens to check for dust and other imperfections. If there are any small specks or clumps of dust it may not be a big deal but larger ones could ruin image quality. If you can, try mounting the lens to a body and switch it around to check for smoothness and focusing. If it doesn’t work well or is making weird noises, it should be returned.중고렌즈
It’s also worth looking at the rubber pieces that hold the lens together and make sure that they’re in good condition. This can be an indication of how the lens was treated and is important as the rubber often acts as a seal between the glass elements and the outside world.
Also make sure that the lens mount is in good condition and not cracked or otherwise damaged. This is the point of contact between the lens and the camera that lets it pass information to the lens for auto focus and aperture control. If this is broken it can be extremely difficult and costly to fix so it’s worth being extra careful when inspecting lenses for this problem.
Lastly, be sure to ask the seller what type of filter thread the lens has and what size it is. This is important because it’s possible for the thread to be cross-threaded, which can cause a number of problems that can be difficult and expensive to fix.강변테크노마트카메라
If you’re not able to examine the lens yourself, it’s a good idea to ask for plenty of photos and to make sure that the seller is honest and trustworthy. Unfortunately, there are some people who don’t do a thorough examination and may hide problems in the hope that you won’t notice them. If you’re willing to take the time to properly assess a used lens, you’ll find that there are many excellent options available for a fraction of the price of new ones. So take the time to do it right, and you’ll be rewarded with great images and a valuable addition to your collection. Happy shooting!
