What is the meaning of "L" on Canon lenses?

"L" usually means that the engineers are trying to make glass do things that it is really not meant to do, so then they have to compensate for natural inferior performance by introducing radical designs and superior optical materials. Recently they have had to deploy a two tier system of "L" glass because some of it just gets too expensive to sell to the masses that they do like to sell to. Then you end up with some "L" glass being even better than other "L" glass. Don't forget though too that some slower non-L glass performs better than the faster "L" glass, except of course at the larger apertures that the non-L glass does not have. Perhaps it stands for "L"ots of choices!

L: Large, they're usually bigger than their non-L counterparts, at

approximately same focal and aperture ranges.

 

L: seaLed, usually better isolated from outside dust, water, etc.

 

L: metaL, the outer cover is metal, as opposed to plastic. All L are metal while only some non-L are metal.

 

L: makes sense onLy if font color is red.

'L'ook again, because a year later you can't really tell much difference in your prints from your 'L' lenses, and your 28-135mm or 50mm f1.4. you can't tell your Canon 50mm f1.4 prints from your Summicron 50 f2 either. you feel nauseous when you start to realize how good modern lenses are, all the money you've spent, and in all the years of your photography you can't site a single image that you've made where the lens made a significant change in the emotional and visual impact of your prints.

 

you remember the olde days and fond memories, where you thought having an 'L' lens on your camera elevated your photography somehow. and now, you have that sinking feeling that it might have been part myth .. the 'L' magic and red-ring, a bit of a marketing scheme. still, you know you have a large aperture, better build-quality, higher-resale value, or other redeeming factor to justify the expense.

 

best of all, you realize that you've grown as a photographer, and that you pick the lens, based on what that lens can do or not do, to best serve the image.
