A new camera lens is an expensive purchase, but secondhand lenses offer the potential to cut your costs. However, when buying a used camera lens, you need to be careful. There are a lot of problems that can befall a used lens, from dust to scratches to fungus, and these can degrade your image quality. The good news is that a few simple tests can help you avoid some of these issues and get a great lens for less.
Before you buy a used camera lens, check its focus and zoom rings. They shouldn’t be wobbly and should offer some resistance, even on lenses that have been used a lot. If they’re loose or easily turned, it may indicate that the bearings have worn out. Listen for grinding sounds, which can also indicate a problem.강변테크노마트카메라
Next, make sure that the aperture ring is smooth to turn and doesn’t have any oil stains on it. Then, test the lens for accuracy by shooting photos of distant subjects such as mountains or oceans. A sloppy focus can cause your images to be blurry and reduce the sharpness of your images.
You should also check the back of the lens for any signs of wear. If the rubber has cracked or peeled it’s a bad sign, as this can affect the lens’ ability to attach securely to a camera body. The contacts on the back of the lens should also be clean and free from any rust or corrosion.
Finally, ask the seller about any previous issues with the lens. If the lens has a history of fungus, for example, it will be very difficult to fix, so you should avoid this type of lens if possible.중고카메라
Lastly, if possible, try to buy your lens locally from a seller that you know. This can dramatically increase your odds of a good, honest transaction and ensure that the lens you’re purchasing is free of damage or defects. In-person purchases allow you to visually inspect the lens and even test it on a camera.
In addition, most major photography retailers have very clear return policies if you’re not satisfied with your purchase. Online purchases are riskier, so stick to established sellers with good reputations and return policies if you’re planning on buying something online.
