Many photography beginners quickly develop an enthusiasm for the creative possibilities opened up by the addition of lenses. But purchasing a lens new is expensive. So it’s not uncommon for photographers to look into used camera lenses to help them get started at a more affordable price. Often, these lenses are purchased directly from sellers they meet through classified sites such as Craigslist and Facebook Marketplace. These trades are “as-is” sales that don’t offer the protection of store returns or manufacturer warranties. That means that buyers must carefully inspect a used lens before making a purchase.
The obvious first thing to check is the condition of the glass elements in a lens. Examine the glass for scratches, dents, or other signs of abuse. Dents merit particular attention, as they may indicate a forceful impact that could potentially knock the precision optics out of alignment, reducing optical performance. A few minor scratches on the front element may not be a big deal, especially if they’re not easily detectable in photos.
If the seller is willing to let you try the lens on your camera body, that’s a great opportunity to examine its overall condition and give it a good workout. Focus and zoom the lens to make sure that they operate smoothly.강변테크노마트카메라 If you hear a scratchy sound within the lens, that’s a bad sign, as it indicates sand or other debris is stuck in the zoom and focus mechanisms.
Also, pay special attention to the rubber parts on a lens. Even if the glass is in great shape, worn rubber will cause the lens to have more friction when operating, which can be a sign of wear and tear that isn’t going to be addressed by replacing it. A rattling sound in the lens should also be of concern, as it could indicate that there’s a loose part inside the lens.
Finally, look at the lens mount and its contacts. The electronic contact points on the back of a modern lens facilitate communication between the lens and your camera, so it’s important that they remain in good condition.중고카메라 Check that they are free of corrosion and not bent or worn, as a bad mount can severely damage your camera.
It’s also a good idea to look at the back of the lens, where you can find information about the lens such as whether it is a U.S. or “gray market” model, which may affect its repairability if something goes wrong with it. If the lens is a gray market model, it’s unlikely that you will be able to send it overseas for repair.
