Hey Jeffrey, mine is my favorite lens, even with a scratched front element. Good choice for a Canon lens, sorry I am not selling mine. With people switching to mirrorless, you might find some price drops.
I have a clean 24-70mm F/2.8L but it's the first version w/o stabilization. Heavy lens but incredibly sharp. I tend to use my 24-105mm to get full overlap with my 100-400mm so the 24-70mm is not an active lens for me.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
