In a video created by Matt Granger a.k.a. “That Nikon Guy” he walks us through the steps necessary for inspecting a used lens before purchasing it. Her they are in order.
1-Look Around The Lens For Signs Of Damage
Start off by inspecting the lens for any signs of wear and tear. Really good lenses especially older ones are built like tanks. So if you see any dents or scratches you can be pretty sure that it’s taken some wear and tear.
2-Check The Element Coating
Next look at the front coating of the lens. Turn it into different angles so that the light reflects off of it. Make sure there is it any trauma or scratches in the coating itself.
3-Look Through The Lens
After inspecting the front element make sure you hold the lens up to the light and look to the barrel of the lens itself. Look for dust. Also if you see hairlines that could be a sign of fungus. Definitely don’t buy a lens you suspect maybe showing signs of fungus.
4- Inspect The Mount & Flex
A little dirt will probably clean right off. What you’re really looking for is any warping. Do not buy a lens that has any warp to it. Also make sure the lens doesn’t have any flex. If the lens is exhibiting flex it may have popped open and then then pop closed again. This way it may not manifest any symptoms exhibited for many of our other tests but is definitely something you want to avoid.

Hello… I was just reading the above article on where to get below market value lens etc… I got a Nikon 18-200mm ED VR digital lens for $20 at a thrift store. I t was in an auction but no one wanted it, there is a minor problem with AF, but very minor… This s a between $600 – $1000 lens and I’ve taken some awesome photos with it so far..

I got my Canon EOS 6D body from a pawn shop for $720.00 And My 24/105 lens from Amazon for $540.00. Both used, but, do the math!!
PS, Both paid for themselves after four wedding gigs!
