The Canon’s L lenses are manufactured in one of three factories in Japan; Utsunomiya, Fukushima, and Oita. As high quality the L lenses are, sometimes there are variations in the reliability and image quality from one lens to another. I see comments all the time; “hope I get a good copy”. Does anyone know if one factory turns out better lenses than the others? Does the year of manufacture make a difference? Are L lenses like fine wine that depends on the vineyard and year to produce a good batch?

I sense that someone is getting carried away with all the hype.

Inquiring minds want to know. :)

Well there is 2 sides of the street you can look at on this subject. Just like anything that is manufactured sure there are some WHAT i call factory freaks. Just like cars ,Guns,etc etc. There are a few that just perform better than the other 100000 made.Or maybe it just the few people that know how to try to squeak every last bit of performance out of 100000 people that have it . Something to think about

Not quite, but there are differences.

Have a read of this (external link) and its earlier linked artice.

Basicaly camera bodies and lenses are built to quite exacting tolerances for consumer devices, but this isnt quite enough to provide perfect images in every combination. A few microns here and there between body and lens and you have 'a poor copy', though prehaps not for someone else.

Having worked in a couple of factories, I can say that the person/people making the product (or operating the machines that make it) would easily have as much to do with it as the location that it was made.

I have made CDs at Sony and also a FDA regulated medical device for a company in Colorado. All it takes is one employee to "look away" or sign off on a bad product. My guess is, this happens everywhere. Especially if you are talking about microns here and there. I suppose if the QC department was superior at one location, they might be more likely to catch the poor copies before release and thus be more likely to "make good copies".

Just a thought though.

Thanks for the link to the article, this helps explain the variations.

Now L lenses I always like to hear about, its such an investment. Although I have some incite on the EF-S 18-55mm IS which might apply to other EF-S if not all canon lenses....

There were two sources for this lens, Taiwan & Japan. After some google research you will see Japan is the favored of the two. They say faster AF. So I got my hands on a 18-55mm IS made in Japan. Did video comparison of the AF & took some photos in RAW to compare.

I felt that the Taiwan focused faster & the photo results were comparable if not better than the Japanese lens. I even kept the Taiwan lens over the Japanese. So I guess that goes to show a good lens could come from any source. Maybe different with L, maybe not.

Given modern multi-factory production environments in just about EVERY industry, when several factories exist, rarely, as in NEXT TO NEVER will the same product be produced in more than 1 of them. By having multiple plants they have have multiple production lines, one for each model (either forever or for a set period of time). Given that fact, its unlikely you'll have the same 70-200 f/2.8 II built in several plants, just 1 of them... There's another reason they do this, they have to train less experts on a given model. Its much harder to train a team for EACH facility to properly produce a given model than just ONE such team.

But, I'd love to know how to find out which plant makes which.

I tell you what; someone I know bought a lens while he was on holiday in Hong Kong! Proper Canon lens but it didn't fit any Canon Body that we tried!
Obviously it was not a read Canon Lens!

frankly speaking, i never saw any lens without the leading U code..
i think all L-lenses are made there.
a mere opinion.
