Canon 15x50 Refurb , is an armor opening supposed to be by the tripod location or is it a crack (defect)? (1 Viewer)

Hi y'all, I just got these and so far tried them without IS. Nice image.

The armor housing seems to have a crack, is this a defect or part of the design? Hard to imagine they can be weather proof with this opening.


What do you think?

In my initial opinion, it is a crack caused by defective molding of the plastic. The molding (or mold design) already looks questionable, with obvious sink marks.

Meanwhile, one of the few images I could find online also had this opening, so now I am doubting if it is a defect or not.

I believe it is supposed to be there because here is a picture of a new pair of Canon 15x59 IS on this eBay ad, and they look the same.

Thanks for sharing that. Well, so far for a sample set n=3 they all have it. Kind of an irregular shape for a seam but so be it. At least it's not a refurb issue!
 
Not the finest craftsman on display, that is for certain. I almost boxed them back up straight away. For this pair it's all about the utility and technology, if they work to their original design I'm fine with it. On the other hand if it were a crack or compromised the weather proof function, that would be a problem.

I would argue that the split is intentional for two purposes. One to aid in manufacture of the covering piece itself. And two, so that it can be installed on the binocular housing. The seam is visible because the edges are not joined together well.

I could see that, and would certainly agree with the conclusion that it is intentional at this point. I was surprised to see it initially, and the non uniformity of the mating edges led me to think it might have been a crack. Preventing cracking at plastic weld lines, especially at boss inserts (tripod mount) is fairly common design challenge.
 
I only noticed it when I was taking pictures of mine for a sale ad. Then came back to my senses and decided to keep it!

I hope you enjoy the 15x50. It's one of the few binoculars that has stayed, while all the others have been sold!

Not sure yet as I haven't fully put them through their paces, but so far so great! Incredible reach as a handheld view.
