Nice video When buying a Canon zoom lens you better test the aperture as follows: - Select Av - Dial in the smallest aperture (like F22) - No look into the lens and keep pressing the aperture-close button on the body to repeatedly open and close the aperture. - While doing this move the lens through the full zoom range a few times. Canon lenses use a small flex cable to control the aperture. If it is unreliable you get a Error 01 on the display. This cable can be fixed at a cost. When you really want the lens get a Euro 150 discount to cover the cost of the repair.

Most comprehensive tutorial on examining used lenses that I've found. Cheers!

Brilliant! I love your tips! Thank you for sharing.

No problem, I'm glad this video helped you out, checking if you're aperture blades work is something a lot of people miss out on

what if the lens that I tested with my camera, the IS function is not doing anything. but when I put the camera on other body it works. then, I find another lens with IS and it work on my camera. what could be the problem? camera: canon 600D lens in question: 18-135 IS other lens tested: 18-55 IS

Nice video good.

Thanks!

why do you recommend using ND filters for landscape photos?

testing a supertelephoto lens that doesn't use front filters (drop in gels)? Focus playback and focus set buttons...I know these are specific to Canon's super telephoto lenses (I'm in the process of buying a used 500mm f4 IS L mark 1).

Thanks for the video.. well done.. In my case, I'm interested in buying a lens on ebay. I'd like to make sure I can get it repaired by an authorized Nikon dealer, if it ever breaks down. Does the serial number help to determine that the lens was intended for USA 🇺🇸... as opposed to an international version?

Only Nikon could tell you this...

💥 No discussion about checking for chromatic aberration.??

Thanks, I have also done well with used lenses. Slightly off subject, I managed to send my lovely Canon EF 24-70mm f/2.8L II USM Lens flying out of my car boot onto the pavement the other day. Now it wont focus, do you think it could be repairable at an economic cost and do you know any companies that may help? Dont want to throw away if I can avoid.

Thanks for the comment! Honestly I'm not sure if that is an easy or hard fix. your best bet is to have a google and see others who might have had similar issues. Hope you get your lens sorted 🙏🏻

Also please tell how to clean lenses so that it will be helpful.

Apparently fungus can even spread from lens to the sensor especially if lens is left on the camera body ....

Good Guide - No. 4 is first for me. this is the biggest nono

Is there any evidence for the lens being around a smoker?

Can a lens with fungus spread across camera sensor?

i have a lens that has some fungus on it. it is a wide range zoom. i leave it on the same camera body permanently. the fungus has not spread to the camera's sensor, nor has the fungus grown in the lens. keeping everything as close to zero humidity as much as possible will arrest any ability to spread.

How bad can a lens be to break a deal? (When cost is also a big limiting factor)

thank you, it's a nightmare. I will just buy new lens.

N°11: If the lens happens to show fungus at least make sure they are comestible.

Seems all used lenses will not pass this test...thanks for the info..

Crazy how a list inflated to 10 fails to mention checking for decentering.

exactly. If you are watching this video and found it to be even remotely helpful, or if you've watched this and called it a comprehensive tutorial DO NOT BUY USED LENSES. It does not even touch on what is actually relevant to watch out for when buying a used lens. Small scratches in the front element are NOT going to affect nor appear on the image. Also, taking a picture at f/22 in the hopes that you're going to see those scratches is preposterous. At f/22 a lot of sharpness is lost and not everything is in focus. Just a word of warning.

Good advice, well done . @frame25_ren
