Jul 18, 2009 - What kind of leses are produced here? Anyway...some steps in the process remind me of the middle ages and i understand why 3 samples of the 950€ Canon 17-55 2.8 i tested all looked different but suffered from extremly soft edges and corners while the press says that this lens is sharp from corner to corner and i have seen samples that are much better than my copy....

They'll probably force-vaccinate many with toxic garbage in Fall, start WW3, implement internet 2 Codex Alimentarius and stage an alien invasion to go a world government with you microchipped, so resist! Support Oracle Broadcasting, Dr. Deagle, David Icke Project Camelot!

Aug 14, 2009 - you should find how they make canon lenses, it's on youtube it's a lot better than this one

mtranda Says:

Aug 19, 2009 - Well, I'm pretty sure you can read about the technological process. However, seeing that it's just a block of glass, I'm pretty sure it's less "interesting", seeing that it will mostly involve a couple of chemical and thermal treatments rather than distinctly different processes.

Sep 1, 2009 - jesus there's got to be a better way

TheCrudMan Says:

Sep 8, 2009 - And yet all lenses, new, used, whatever, typically have dust in the optics that doesn't effect the image.

Oct 16, 2009 - I suspect if the particles were large enough they would affect the image?

gonepishing Says:

Oct 30, 2009 - soooo much manual labour

wlolold Says:

Nov 7, 2009 - Six weeks for one lens?!!! That can't be how major manufacturers operate! Impressive as it looks, it doesn't seem very modern and efficient! Like gwhoosh said, the process today must be much more automated with less room for human error.
