Ignorance is bliss.
For years, I have been happily running around with my Sigma and Tamron lenses, taking pictures and thinking my glass was pretty good. I mean, they're a little soft wide open, but every lens is like that, right? Why pay more for the fancy Canon name brand and the red ring when this aftermarket glass makes perfectly fine pictures? L glass is a waste of money, I say!
Then my wife bought a 100-400L. And I used it a little. And I quickly came to an undeniable conclusion:
L glass kicks ass.
Detail, color, contrast... holy MTF charts, batman! This thing is in a different league than Sigma & Tamron. And image stabilization opens up new possibilities, too.
I went through the process of calibrating all my lenses with the AF microadjustment feature of the 1D Mk III. The Sigma & Tamrons all needed some tweaking (little wonder the Sigma 70-200 rarely focused correctly on my 20D). The 100-400L was bang-on. No tweaking required.
Now recently my wife nagged me until I relented and approved the purchase of a 24-70L (She says it's her lens. She's in for a rude awaking on that.). First thing I did was take some comparison shots using it and my Tamron 28-75. Which confirmed my earlier conclusion:
L glass kicks ass.
So now I'm looking at the picture of the EF 70-200 F2.8L IS on the B&H website, drooling like some kid with his nose pressed against the toy store window, wondering how I'm going to resist the urge to drop another $1,700 and put my Sigma days behind me.
The problem is, that won't be the end of it. Next, I'll "need" a 17-40 too. And God knows what else. Maybe an 85L or the whole blessed holy trinity of primes. Or maybe something long and fast like a 300 f/2.8
Pity me. I have ventured down a path with no return that will suck me dry. I will die broke, and my kin will have to sell my gear to pay for my funeral.
