My original 24-70/2.8EX fixed in Japan

Here is a 70mm text shootout between the 24-70EX from fStopJojo, my original 24-70EX after "adjustment of 2nd element" in Japan, and my extremely sharp 70-200/2.8L. All squares are 100% crops of completely unprocessed images (of Feininger's excellent book _Total Photography_ propped up at a 60-degree angle and turned to the very well-written page 21, where he sings praises to lens testing ;) ) taken straight from my 20D in Best JPEG mode, Parameter 2, taken indoors under incandescent lighting using AWB, Manual mode (with identical shutter speed and aperture combinations used between the 3 lenses), ISO 200, on tripod, MLU & 2-sec timer, AF'ed for wide-open shot and then kept the same focus for all shots with that lens, shot several runs and picked the best run and runs that had the same exact focus point for all 3 lenses.

I'm interested in buying a 24-70, what should I look out for and how do I test it?
PS. I'm using EOS3 with slide film.

Looks good, Lincoln. As you know I recently picked up a 2470EX and it's excellent. Glad it's worked out for you. You've got yourself good copies of both the EX and L here. Best wishes...Jojo

Well sorry anyone who was interested in an auction for my original 24-70EX that I went through the legwork of ensuring is a sharp copy - rather than succumbing to my curiosity as to how high an auction might take this item, I just sold it directly to fellow member Benchernif for the bargain of $365 shipped. Here's what he had to say today when he received the lens and tried it out: "You were quite right: I want to say that this lens is even sharper than the last one I owned, and a bit sharper than the 24-70L I just got rid of. Amazing. Thanks for the great service and product, I am very pleased." So good luck everyone who orders this lens, hopefully you get a sharp one! If not, you might try Sigma Japan for a tweak.... --Lincoln :)

So who wants to buy a nice sharp 24-70/2.8EX? I think I'm leaning toward letting my original go, not because of any noticeable difference between the two 24-70EX's, but just for "sentimental reasons" because I like knowing my lens is fStopJojo's infamous "L-killer." :) Again, I'm still hoping to do an outdoor shootout with both these, my 70-200L and a friend's 24-70L, but it just hasn't happened yet. Perhaps I should produce that supporting evidence before putting the 24-70EX up on eBay.... --Lincoln :)
