went out this morning with the 200-400. God I'm tired! It sure does work fine with the 1.4x on it. this guy was far away, and even at 550mm this is cropped. This shot would have been easier with a tripod: NIKON D2H    ---    550mm    f/5.6    1/640s    ISO 320 NIKON D2H    ---    550mm    f/7.1    1/500s    ISO 320 someone told me about an osprey nest in Port St. Lucie, and I found this osprey building a nest. Too bad I overexposed by 1/2-3/4 a stop NIKON D2H    ---    550mm    f/9.0    1/200s    ISO 320 I printed an 8x10 of this for my dad: NIKON D2H    ---    550mm    f/5.6    1/2000s    ISO 320 I'll go back in the afternoon, it was getting too hot to lug that big rig around. I need a nap.
