Yeah, I know this isn't PFS; however, this is where the shutterbugs are. Without further delay.
I just bought a (another) new Canon 70-200 F2.8 L IS lens and will be offering my 70-200 f4 L for sale. I also will be selling my Canon 100-400 f4.5-5.6 L IS lens. After this weekend I will place ads on the photog sites that I frequent, so, they will be available for a short time only. Lenses move fast there, so if you're interested, speak up quickly. Shoot me an email at firstname.lastname@example.org. PM reviews are hit & miss for me.
70-200 f4 L $500 shipped to lower 48 states
100-400 L IS $1000 shipped to lower 48 states
There's some wiggle room on the price if you want both (or go in with a friend). I'll eat the pay pal fees.
