Know your seller
You do not have to take them out for supper or anything, however it’s a great idea to talk with the individual who’s selling you a lens. 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
This is the tried and tested method to examine if large dust clumps or fungi have got inside a lens- shine a light through it and take a look at exactly what appears. Minor dust specks won’t be a problem, but larger ones can impact operation and image quality. Open the aperture all the way and check thoroughly. If you see any kind of large areas in the light path then the lens is in trouble and you’re finest off keeping your money.
Check the AF
Hook it up to a camera and start focusing. Obviously different lenses will have different autofocus actions, so this is where it’s a great idea to investigate your lens in advance.

Likewise make certain to look for zoom creep: this is when a zoom lens’s zoom action wanders when pointed downwards. A few of this can be anticipated with heavier lenses, however if it happens too quickly and freely then you have a problem.
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. The viscosity produces friction and restrains smooth aperture changes. It needs to be visible on the blades as you change them. 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!
