There's really not much point to this comparison unless you do so. Since colour is merely reflected light, unless the lighting is the same for all four shots it's a waste of time.

My original shots were not to compare the four lenses. One pair of shots was to compare Canon vs. Tamron, the other pair were to compare L vs non-L Canon. I have reshot all lenses, and added a fifth one to the series. In the shots you can see a bit of fence behind the MacBeth card, so that you have a real world object to see if subtle color is more apparent in better color reproduction via the L.

Here is the process I followed...I shot all lenses per gray card reading (all shot at 1/320 f/4), as rapidly as possible to keep light conditions as identical as possible. I read the RAW files into Lightroom, I put LF into grayscale mode to establish identical density of the 18% gray patch on the MacBeth card and then reverted to color mode. One of the shots (it obvious which one) is warmer than the others, so I took that shot and neutralized it in color balance with the post processing WB tool and added it to the series to see if people could figure out which shot is the WB corrected shot vs what comes out of all the lenses.

What's the difference between a L and an non L lens?
Is it sharpness, speed, AF speed, build quality or all of the above?

You really do not need neither 24-70 nor 70-200 in a studio. You are not going to use that 2.8 on an aspiring model under strobes so keep your money. Almost any lens will do just fine. You need highest end lenses for challanging situations such as low light, extra demand for speed etc.

It is the red band on the end of the lens.

I dunno which is which, but the third one has the most contrast. The first one seems to have the least contrast and softest edges. Second is middling in contrast..second best? The last two are from the same lens, and has a contrast in the middle as well. Best edge sharpness goes to the second or the last.

Gawd, I hate it when my own laziness comes back to haunt me! I set that outdoors and the shooting angle wasn't sufficiently consistent from shot to shot to to elevation differences of my standing position, causing a bit of surface sheen to arise. I'll shoot this once again, this time indoors, and this time include some flowers in the hopes that subtleties of color could also be perceived, where the MacBeth card alone might not reveal differences. The shots will be posted in the same sequence as previously, and inserted into the prior post.

L ? Who is that L you're talking about? I sold my 70-200L ages ago, and only own one ultrawide L, which I find nothing special, but drag it along when I'm going on trips. Except for a few highly expensive and gorgeous L primes, I would not bother with the price, weight and size of a zoom, be it red-ringed or nay.

Shooting models using lights? Shooting flowers and insects ? What do a 24-70 or 70-200 zoom have to do with that, except looking impressive ? :)

Canon 85mm f/1.8 wide open, Canon 100mm f/2.8 Macro wide open on the second.

Wow, I was trying to decide if I needed a prime and now I'm sold. I wanted either the 85 or the 100 but those two images make it near impossible to decide.

Personally, I have the Tamron 28-75mm and I love it. Here are some example images shot yesterday with the Tammy....

There are a lot of young, impressionable photographers on this forum that have not used brands other than Canon and who are greatly influenced by what they read online, etc.

It's a fact of life that people on forums parrot what they have read, or are very influenced by well-orchestrated marketing campaigns.

Aside from sometimes dubiously better "build quality", you don't need expensive "L" lenses to get excellent photographs.

In a controlled blind test, I don't think anyone could tell the difference between many cheaper lenses and "L" lenses.

The claims of "higher color saturation" and all these other fanciful qualities of "L" lenses is basically nonsense.

If you don't need specific features of certain L lenses, such as aperture speed or zoom range, just buy something cheaper.

Spending thousands of dollars on expensive lenses won't improve your pictures.

I have noticed that my L glass is a bit faster on the AF then my non "L" glass and hunts a lot less in low light (though to be fair the only non L glass I have is a 50 1.8 and a tammy 17-50 2.8)

Disagree there. Color is where I see the biggest difference outside of build quality.

All true.

In a controlled blind test, I don't think anyone could tell the difference between many cheaper lenses and "L" lenses.

You can when shooting at apertures of F/2.8 or faster, images not processed beyond "faithful", and viewed or printed at large enough sizes.

The claims of "higher color saturation" and all these other fanciful qualities of "L" lenses is basically nonsense.

See above.

If you don't need specific features of certain L lenses, such as aperture speed or zoom range, just buy something cheaper.

All true again.

Kind regards, Wim

In Wilt's test (which I took blind) I preferred the 70-200 and the 17-55.

I'd have to say, L lenses do seem to have a colour advantage. IMHO the colours from my 200 2.8L and 24-105L seem richer and just nicer most of the non-L lenses I've owned/tried (17-55 is the exception, though generally I prefer the 24-105 colours...)

Maybe it's just my imagination though...
