How lenses are made

Since everyone here uses lenses, I just want to share this video I found on YouTube to those "Discovery / NatGeo" persons out there like I am. ;D .... but then again, having birds as the subject of our passion, I guess we are all Discovery / NatGeo persons after all. ;D


How camera lenses are made:



Now for those using the Canon lenses, here is how their lenses are made (specifically the EF 500):

Thanks. I must have went "oh so that's why" a couple of times while watching the first video.

Same here. Now I know why those lenses are soooo expensive. ;D

After watching the videos, am now worried about buying lenses. We really need to be careful when choosing not just the lens but also the vendor.

My new rule for buying a lens:
1. Make sure vendor will give full warranty/replacement even if just for a one week coverage.

Reason:
I saw that during the production, there are several chances for the quality to get compromised. I guess there really is a "round robin" thing when it comes to buying lenses. I mean, the firs video started of with a glass block, that cannot guarantee 100% quality, and then the assembly process..

And yes, it's an eye opener when it comes to prices
