A used camera lens is a great way to get tack sharp glass at a fraction of the cost of a new one. However, it’s important to inspect the lens for wear and tear before handing over any cash. There are some pitfalls to avoid, especially when buying from private sellers through classifieds websites like Craigslist and Facebook Marketplace. When you buy from a used dealer in person, or online, you can rest assured that the lenses have been thoroughly inspected by a professional. However, when you are buying from a private seller on Craigslist or Facebook Marketplace, or even from a camera store in the mall, you’re left with your own inspection skills to determine if you’re getting a quality lens for a fair price.

Before you take the plunge and buy a used lens, start by looking at the pictures on the listing. A good seller will include real images of the lens, not photos taken in a studio and then digitally altered to hide any scratches or blemishes. Look for any significant differences between the pictures on the listing and those on the lens itself to see if there is a discrepancy.

Check the lens for scratches and dents – minor scratches on the front lens element are not uncommon and should be expected, but major damage to the lens coating or evidence of fungus is a big red flag that the lens is damaged or has been disassembled and improperly reassembled. Examine the screws and rubber pieces holding the lens together – marks on them indicate disassembly / reassembling, which could mean that there was a mechanical or electronic problem with the lens in the past.

Look at the back of the lens for the contact points that pass the information to the body for auto focus and aperture control.중고카메라렌즈 These are usually gold and if they haven’t been kept clean by the previous owner, they can build up with dust, dirt and grime. If there are any signs of this, it’s a good idea to replace the lens before using it.강변테크노마트카메라

Next, open up the aperture and shine a light through the lens to inspect for any dust particles or other internal damage. If the lens is a zoom or wide-angle, it may be hard to see this clearly, but if there are any dust specs floating around the inside of the lens you should think twice about buying it.

Finally, test the lens by attaching it to a camera and making sure that there are no looseness or rotation of the lens axis when turning the zoom or focus rings. It’s normal for there to be a little give, but you don’t want the lens to tilt or rotate, and if it does, that could mean that it isn’t aligned properly with the image sensor and could produce distorted or blurry photos.
