Do rival manufacturers buy competitor's products and tear em apart for evaluation??

i'll be very very surprised if they don't.... part of competitors' analysis, and reverse engineering...
someone probably hired the other side's product engineer... i won't speculate who, since that would in all likelihood start another flame war... :rbounce:

Hmmm.. does your company do that then? ;p
nikon : hello , is this canon service center?
canon : yes, how may i help you?
Nikon : I'm from Nikon, you see. We wish to rip open one of your model for testing purposes, i wondering if you can loan us a set?
canon : click ................

nikon buys canon cameras and reengineer. thats how they got VR.
i hope no flame intended! :devil:
from what i know from a friend who was working at adaptec, the company with send them rival company products and they will take it apart and see what works and try to make something better. that is their research and development.
Hmm, if you are talking about Nikon or Canon, I seriously doubt they will do reverse engineering. Both Nikon and Canon are too proud to do it anyway.
If you are talking about small timers, well it will be another story.
Regarding the image stabilizer (IS/VR/OS) is not invented by Canon, that's why Canon doesn't have worldwide patent like when they invented USM powered lens. When Canon invented USM in 1986 it really kick Nikon out of water, Nikon catch up with it more than ten years later with AFS version lenses. The world wide patent expired after 10 years, we see first AFS lenses in 1998 or late 1997, if I am not wrong.
I read this in the website in US but I can't recall the address.

I'd love to know what website it was, because they don't know what they are talking about. Ultra Sonic motors, or more correctly Piezo Electric Effect Motors were NOT invented by Canon.
It should be noted that Canon did not develop piezo-electric motor technology, it merely adapted
it for camera use. The original patents are held by Shinsei Kogyo, a smallish Japanese manufacturer who holds the key patents for piezo-electric motors, issued in 1983 (from memory) and who had their technology
lifted (read stolen) by Canon etc though a peculiarity in the Japanese patent laws that allows other companies to copy the technology and apply it to a different field and apply for patent protection.
Nikon actually caught up in the AF speed race in 1992 after the release of the AF-I series of superteles with DC coreless motor drives. These lenses are as fast in AF as SWM/USM lenses when used in the field.
