Other than for speed? Color, sharpness, distortion, vignetting, CA etc etc can be corrected/modified in post.
I used to shoot JPG and do a LITTLE post here and there. But now I find myself shooting in RAW and doing post to 99% of my shots. There's ALWAYS something that I want to do to it, whether it be adding a little contrast here, fill light there, sharpening... and it doesnt take long at all to sync the settings to all my other pictures. It was a a daunting task in the past, but now it just takes minutes to edit a batch of files.
I can probably make a $100 lens look better than a $2000 lens with 30 secs of work... so is there really any "optical" advantage of having a L over a bottom of the barrel lens?
Instead of recommending someone a L lens from now on, maybe I'll just tell them to learn how to post process a little better.
The only thing I can deduce from your post is that you are not putting REAL demands on the quality of the work you produce.
If you were, you would not be suggesting that you can introduce sharpness that wasn't there in the first place. Certainly there are very sharp non L lenses for certain applications. the EF-S 17-55 2.8 is, I believe, very sharp, but I can't use it on my FF camera. My 100 macro is very sharp and gets used regularly.
But when I bought the TS-E 17 it made my 17-40L look soft at that focal length and no amount of PP work could change that.
When you are making large prints you do notice these things. Not all L lenses are sharp across their range, but they tend to be the best available, so if one is fussy about quality, specially if you're presenting work to clients, then only the best is good enough.
The "bottom of the barrel" lenses you seem to be extolling are pretty awful when examined closely, and it's all very well saying that all those abberations can be cured in PP, but that just isn't so. It's all a matter of what you're prepared to call quality work I suppose.
Good on you for getting so competent at PP, though. Mind you, with all those L lenses you have, I wonder why you needed to!
