If you can get referrals and references regarding their good character, all the better (if you’re on eBay, prevent individuals without any feedback from buyers). It’s worth asking the seller why they’re selling the lens- if they do not have a gratifying answer for this question, they may be attempting to offload a faulty lens onto you.

Check out the body

First things initially. This is the most fundamental and essential check you have to do, however it is essential not to overlook it. Analyze the outer body of the lens, search for nicks and scratches. A couple of dings
are great and will not affect the operation of the lens, however be alert for any that look more severe and ask your seller about how they occurred. You actually can’t be too extensive at this point.

Shine a light

Examine the aperture blades

A lens that has actually sat unused for some time, and specifically one that has actually been saved in too warm an environment, can develop oil on the aperture blades, and this does not help them run smoothly.

However, you can also inspect utilizing the depth-of-field preview function, if the lens has it.

Inspect the images (properly)

This is the last, crucial step. Do not settle for checking images on the rear screen. Get them onto a computer with a good monitor, blow them up and examine them. You do not have to be a pixel peeper for this to matter: today’s little speck can quickly become tomorrow’s shot-ruining acne that transforms your lens into a pricey paperweight. Bring a laptop computer along to your purchasing fulfill if you desire, and check them on the spot. You can’t be too careful!
