I would like to trade or sell my 300 L f/4 is for your 70 200L f/4 or 70 200L f/2.8 and money on either side depending on the lens. If you want to buy I will sell for $1000.00 The 300 is in perfect mint condition. I am photographing my kids baseball game and the 300 is to long. I have field access and the 300 is very limiting. Let me know what you have and the deal you want to make. I can email some pics.
