Red Dot = Refurb
Jun 30, 2016 16:13:41 #
I'm in a discussion with a guy that offered to buy my Canon 70-200 2.8. He informs me that it is a refurbished lens and how he knows is because there is a small hole next to a screw on the face of the rear mount and it has been painted red. "Dead give away" he says.
Well, I purchased the lens new from B & H several years ago as new, came in a red, white and black box and nothing else that would indicate it is anything but new.
Canon tells me the red dot does NOT indicate refurb however they have not said what it does mean. I do not believe there is someone running around the factory just painting in the hole red because they have nothing better to do.
Anyone shed any factual , (not opinion) light on this?
Thanks in advance.

Could it be something like "Locktite" on an adjustment screw that has been calibrated?

Sounds like this buyer is trying to feed you a pile of S*** to get you to lower the price with some fairy-tale. If you were to sell it to him he'd probably later claim the lens is defective with some mystery ailment. I smell a crook. Move-on, find another buyer. Yes, there are various variations of Canon mounts and lenses with incompatibilities that are marked in various ways, circles, squares. I've seen friends cameras and lenses. Take care, good luck.

I'm not sure what that means. As far as I know, and I've been using them for years, the Canon EOS camera system has 2 types of lens mount, EF for all EOS SLR cameras and EF-S for crop frame SLR cameras. EF lenses (red dot) will fit a crop frame body and a full frame body but EF-S lenses (white dot) will only mount to crop frame bodies. I know nothing about EF-M since I don't have an EOS mirrorless.

Manufacturers of High Value equipment will put secret colored dots and may change the product in a very minor way .. to say what country is was exported to etc.
This is usually for Customs at Borders to know if it was bought in the arriving country or not ..
EG .. a person may leave Australia go to a Country where cameras are Cheaper ( and possibly duty free ) and bring it back ,but when challenged
by customs to pay import taxes on the Camera .. the traveler may say .. ' oh but i got it in Australia and been traveling with it ' .. The customs with
their knowledge of which Dots are for which countries will call his Bluff .

I've seen a splash of red paint on all sorts of fasteners as a product comes from the factory. As you said, it probably indicates that someone made sure it was tight or calibrated. I've never seen red paint on a lens or camera screw, though.

Canon sells refurbished lenses in a white box with red "Canon" name underlined with 7 black lines. I have a 70-300 f4-5.6 IS (USM) that I bought direct from Canon in this box. There is a RED dot in the "locking hole" on the base. It is a good lens for the price.

Just took a quick look at my Canon lenses. There IS a red dot on the mounting surface of the one refurbished lens I recently bought from Canon USA (probably loctite or glyptol). There are no dots on any of the other lenses.

There is one thing I can tell you, be careful with the buying practices of your friend.
If you bought from B&H and they sold the lens as new it is not refurb. B&H is a company with an excellent reputation and they are very serious about their business practices.
I have nothing against a refurb item and as a matter of fact I have bought refurb in the past with entire satisfaction of the products I bought. A refurb camera or lens is in the majority of the cases an open item that is returned to the importer who puts the item through the same tests as if the product has been out of the assembly line and released to re-sell only when it meets their specifications. Cameta sells refurb products and adds a one year warranty. Highly recommended.
I am not familiar with Canon products so I cannot issue an opinion about the red dot you mentioned.

I, too, checked my Canon lens and on one of my refurbished lens (70-200mm f/4 IS USM) there is red magic marker ink in the hole where the pin from the camera fits into.

In the manual for one of my older caneras it said to align the white dot on the lens to the white dot on the camera body when attaching the lens. I noted that where the lens had a flange the camera body had an opening. The two flanges were unequal in size. Aligning the dots helped get it right the first time. After a couple of lens changes one got used to not needing that helper much. Perhaps the red dot is that manufactures way.
