Just jumped a 'like new' 5d3 from amazon.. I've bought used/refurb many times before but not for an item this expensive, so I want to test it.

anyway, any tips on what I can do to make sure it's working perfectly? I can easily return it if there is even the smallest thing wrong with it.

I am referring to dead or hot pixels, banding issues, sensor issues, etc. anything really.

Thanks fellas!

I never had a 5d mk3, but when I bought my 7D I shot with it and looked at the photos :)

Drop it to see if they really do bounce.

Open it up and see if the flex wires are intact. Take out the shutter box and hook it up to a 12v source and let it run at least 500 actuations. Take the top LCD off and look for light leaks. Submerge it and check the weather seals.

and do the bounce test

Where did you purchase it from? A reputable dealer? Locally? Internet?

Hi JS - congrats on the purchase.

The best way to test the body is to just go ahead and use it in the same fashion as you'd normally take pictures. I don't own any electronic test gear, so unless you want to pay a repair facility to evaluate it just put it through it's paces. Switch out lenses, shoot under a variety of lighting conditions, use your speedlight, swap CF cards in and out, and while processing the images look for anything significantly out of the ordinary.

Looking at your equipment list I'd suggest that you already have enough gear experience to know if something is amiss. Enjoy your new investment :D. - Stu

It should float in salt water.

Like everyone says, shoot with it awhile. If you bought through the Amazon Warehouse deals, their "like new" are often items that someone bought and returned for some reason. I've heard many stories of the items being basically new and working fine.

There's no magic bullet test to see if something is wrong, just use it.

No, actually it's not. More than likely it's a question too technical/picky for the people that populate this forum. My mark ii has a few hot pixels and always has (i think), it also has faint vertical banding when I mix long exposures with a certain type of post processing. There are plenty of other 'minor' issues that exist out there, and i simply wanted to see if there was a dedicated/easier/exped​ited way to check these things.

maybe you shoot snapshots of dogs or flowers or something, but for my type of work these small flaws can add time to my workflow and can get annoying.
