How to Avoid Buying Used Camera Lens With Optical Problems

Used camera lens are a great way to save money on high-quality glass. The cost savings can make the difference between a mediocre lens and a stellar one, or even allow you to afford a rare or discontinued lens that wouldn’t be available new. Plus, lenses typically hold their value better than cameras, so you can usually recoup much of the purchase price when you sell the lens later.중고카메라

However, buying a used lens isn’t without risk. There’s a real possibility that you could buy a lens that has serious optical problems, and that can be very expensive to fix or replace. Fortunately, it’s pretty easy to avoid making this mistake, so you can save yourself some headaches and cash.

The first thing to do is check the lens for signs of physical damage. While small scratches and dents on the lens barrel are not a big deal, larger ones may indicate that it has suffered from mechanical damage in the past (like dropping) that will affect its optical performance. Dents near the lens mount are particularly troublesome, as they can cause the lens to focus incorrectly.

If you’re buying the lens in person, ask the seller to let you mount it on your camera and test it thoroughly on-site. If they refuse, they might be hiding something. If you’re shopping online, request a refund if the lens doesn’t work as advertised.

When you inspect the lens physically, look for dust specks and other cosmetic damage. While a few dust specks are no big deal, if the lens has significant blemishes or obvious signs of fungus or mold it should be avoided. Fungus and mold can damage the multicoating of the lens elements, and cleaning might not reverse that damage.

Also pay attention to the condition of the focus and zoom rings. They should rotate smoothly and offer little resistance. Listen carefully for any grinding noises, which could be a sign that there is dust trapped inside the lens.중고카메라매입

Finally, be sure that the lens mount is in good shape – it should have the right threading to accept filters. It’s a good idea to remove any filters that are already attached, as this will give you a more detailed look at the condition of the lens and will show you whether or not the lens has been damaged to the point where it is no longer functional.

Once you’ve done a thorough inspection of the lens, take some photos with it and look at them in detail. If the lens is a premium lens, it should produce sharp, clear images. If you find that the images are too soft, or that the lens focuses incorrectly or has other mechanical issues, it is probably best to walk away. Hopefully, by following these tips you can find a used lens that is a great value and will serve you well for years to come. Happy shooting!
