Purchasing a used lens is a great way to get an excellent quality lens at a fraction of the price. However, it’s important to do your research before handing over your money. A few simple tests can help you avoid buying a lens that doesn’t perform as intended or is damaged beyond repair. 중고카메라렌즈
The first thing to do is look at the lens carefully. Scratches and a little bit of loss of paint or rubber are to be expected, but if you see dents or dings on the front or rear element then it’s time to move on to another seller. These dents can cause a noticeable reduction in image quality.
Next, use a bright light to check for dust and fungus on the inside of the lens. Fungus can eat away at the glass, making it less clear and reducing image quality. Luckily, most fungus can be removed with a special cleaner that can be purchased at any photoshop. However, if the fungus is widespread then you may have to send the lens back.
Finally, test the lens by using the middle autofocus point in good lighting. Focus the lens on something close up, then off in the distance. If it has trouble transitioning between the two, or if it makes a strange sound as it switches between the focus points, that’s a sign there’s something wrong with it.
These tests are a lot easier to do in person with an in-person sale. Unfortunately, most online and eBay sales don’t offer this opportunity. If a seller isn’t willing to let you mount the lens on your camera and thoroughly test it, then you should probably pass on that sale.
You should also ask the seller why they’re selling the lens. There are plenty of legitimate reasons to do so, such as switching platforms or upgrading – but the lack of a reason could be a sign that there’s something going on behind the scenes.럭키카메라
Lastly, you should always be sure to buy from a reputable source that offers a return policy. This will give you peace of mind knowing that if the lens is defective or doesn’t work properly, you can return it. Most large photography retailers and high-reputation sellers will have this option. If you’re shopping on Craigslist or from a private seller, you should be extra vigilant.
