So yeah, mostly it's the red ring and it's like one of our esteemed (or not so much) US congressmen once said about p0rn - you know it when you see it.

Actually, it was Potter Stewart, an Associate Justice of the United States Supreme Court, someone far more esteemed than some unnamed congressman.

Quote
I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["hard-core pornography"]; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that. [Bold added.]
—Justice Potter Stewart, concurring opinion in Jacobellis v. Ohio 378 U.S. 184 (1964)

Justice Stewart also later rued having made the statement. He recanted this view in Miller v. California, in which he accepted that his prior view was simply untenable.

FWIW, I know "it" when I see it too.

And this lens isn't.

Great for many other reasons though.

Don't worry, you are in good company, I can't recall Canons definition of L.

Here you go...

Quote from: Canon, Lens Work III, p.15
The bright red line engraved on the lens barrel. And an L for “luxury.”
The Canon EF lens L series possesses a level of quality sufficiently high to be called professional,
designed to include groundbreaking image performance, outstanding operability, and resistance to weather and aging. “L.” This name is reserved only for those few lenses that can meet stringent standards of performance,
using fluorite (an artificial crystal), a ground and polished aspherical surface,
UD, super UD lenses, or other special optical materials.
Optical design without compromise together with optical theory and precision engineering
technologies that are as steeped in tradition as they are cutting edge.
And the result of our relentless pursuit of these ideals is the L series of Canon EF lens

"L" is for "Luxury" or for "as expensive as 'ell".

Hmmm. 'without compromise' is a bold statement, if that were true then almost none of the 'L' lensed could be afforded by mere mortals ;)

No, you misunderstand. I had actually read that. It doesn't actually say anything.

I'm just wondering which part of the marketing speil we should use as a distinction of 'L quality' as this seems to be benchmark to which all lenses should aspire.

I have L glass, i've owned and sold L glass, and I've loved using them, some have been good, some have been brilliant, but other than the red ring there is no single technical aspect that anybody anywhere can use as a distinctive measure of 'L quality'.

'L quality' is not a measure of anything.  So its pointless to describe or compare the 55-250 to 'L quality' as a generic benchmark.  Compare it to a specific L lens by all means, but 'L quality' is an entirely arbitrary pretext.

That is all.

It's not pointless at all, IMO.  For example, there's no L lens with a plastic mount.  The EF-S 55-250mm has a plastic mount.  Not L quality.  Simple.

Ummm, I'll take a plastic mount for 1/10 of the price if all else is equal

Neuro, I don't know why you are even bothering, they clearly aren't making this lens for somebody like you.  It's too small and light for you not to loose it in those deep pockets of yours.

But I'm glad we are getting to a shortlist of things that make an L lens an L lens.

1. Red ring
2. Metal mount

Although I am aware that there are other lenses also have a metal mount that aren't L lenses..
Maybe I should make the list of things that make an L lens exclusively an L lens.

So I'm back to:

1.  Red ring.

I know you are an educated man, so I know you'll get the difference between me picking holes in the use of the term rather than decrying L lenses as products. 

This 55-250 IS lens looks like a great addition to Canons range, a good value, well performing lens with hopefully a modest price.  I don't know why 'L quality' or not has to come into it.  Mainly because the term 'L quality' means very little, it may allude to a set of expectations (some of which not every L lens will even match) but to a potential buyer of this lens, 'L quality' means nothing.  And it's not marketed as being top end.

I, admittedly, don't know enough about the L line to be able to do this myself, but I think it would be pretty funny/alarming for someone to make a mock marketing campaign about a forthcoming L series lens which said the lens was on par with the very worst of the worst attributes of well known L lenses.  For instance...

The new _______ L has the build quality of the (insert poor build quality L lens here), AF speed and accuracy of the (insert worst offender here), weather sealing and durability of the (insert worst here), etc., and it's only 2x the price of (a fantastic performing 3rd party lens of equal focal range, but faster).

I agree Paul13walnut5, there's no single specific attribute that can be assigned to the L series.

I have no pony in this race, but having deep pockets does not imply willingness to throw one's money away, nor the ability to recognize a bargain.

If the only difference between "L" lenses and others was a plastic mount, and if one could get them at 10% of the cost, one would be foolish not to fill their bag with lenses that have plastic mounts. After all, if the mount breaks, one can throw away the lens (many times over) and still be ahead of the game.

The new _______ L has the push pull design of the 100-400, the extending design of the 70-300 L, the AF speed of the 24mm TS-E and accuracy of the 50mm f1.2, weather sealing of the 70-200 f2.8L corner optical quality of the 17-40 wide open max aperture of the 400mm f5.6 and durability of the (insert worst here), etc., and it's only 2x the price of sigma 18-35 f1.8.

Yeah, I get it...and you're right, there's certainly not 'one technical metric' anyone can point to, that defines a L lens.  It's more of a combination of elements - better build, faster aperture than other lenses of similar focal length(s), constant f/number where another zoom might have a variable aperture, weather sealing in some cases, etc.  You also have to keep the timing factor in mind - weather sealing is a (relatively) newer feature, with the exception of TS-E lenses, all of the more recent L-series lenses have sealing.

I was making a joke.  Neuro has the best of gear. An abundance of the best of gear.  Other than liking to have his say this lens isn't on his radar.

I'm making two points here.

1. The lens is a god send to all the folk buying canon gear within modest means.  Canons ability to make good gear at competitive prices is the key to their success. 

I recall Neuro saying his first DLSR or first Canon DSLR was a 500D.  I'm willing to be corrected on that, but if I'm right, canon pitched their entry level 500D perfectly - it worked well enough to bring folk into the system, and gave folk enough taste to go onto to better more expenisve things.  The 500D was good business for Canon in this case, even though there would be contemporaneous pundits on forums like this going 'aah but it's not a 5D mark 2, is it?'  So much like this lens.  Todays first time DSLR buyer, or person expanding their rebel kit might suddenly have an epiphany using this lens.  They might get the sharpest wildlife or sports shot they've had to date.  They might get the taste to really get into their photography.  Or it might give them a shot of a loved one that wouldn't have been possible with their 18-55.  I'm all for great lenses for little money.

2. 'L Quality' doesn't have any meaning. 

and I suppose ..

3.  The death of APS-C has been vastly over-stated.
