A used camera lens is a great way to save money and get some of the best lenses on the market. However, it’s important to make sure the lens works properly before you pay for it. Buying from a reputable dealer is probably the safest option, as they will thoroughly inspect the lens to make sure it functions correctly before selling it to you. However, this can be costly, so purchasing from a private seller is often where the best deals are to be found.
Regardless of which method you choose, when buying a used lens it is always a good idea to ask the seller if they will allow you to test it out on your camera. This will give you an opportunity to see if the lens works with your specific system and to check for common problems such as dust, scratches and fungus in the lens element. If the seller is unable or unwilling to let you test the lens on your camera, you should move on to a different seller.
Before you test a used lens, take a close look at it and examine the overall condition. Scratches, dents and dings should not be ignored, as they could indicate that the lens has been dropped or mistreated.
You should also examine the lens mount and focus ring to make sure they are free from dirt, grime and corrosion. A gummy, sticky lens mount will not hold a filter properly and can cause serious damage to the lens itself. Finally, the zoom and focus rings should have some resistance when you turn them. If they are too easy to turn, they will be worn out and may not work well.중고카메라렌즈
Once you have a good look at the lens, shine a light through it to check for any imperfections that might be present. Small scratches and dust particles should not be a big deal, as they can easily be buffed out. If you see any signs of fungus, however, it should be a major red flag – fungus will eat away at the lens element and ruin image quality.
Lastly, you should ask the seller why they are selling the lens. There are plenty of valid reasons for selling a lens, such as switching systems, upgrading to a new camera or simply not using it much anymore. A lack of reason, on the other hand, can be a warning sign that the seller is trying to hide a problem with the lens. If they are hiding a problem, it is unlikely that they will be willing to let you return the lens. If you buy from a private seller, this is even more likely to be the case.
