I've been using one for years (with A*400/2.8, FA*300/2.8, F*600/4 & DA*300/4) and have been quite pleased.

You do realize that a 22% increase in resolution is the difference between 400mm lens and a 500mm lens?
And do you realize that the difference 1.22 crop factor will only narrow FOV going from 400mm to 488mm, for wildlife photography that sits near the bottom on my concerns when I go out and photograph

Ya right, so you're saying forget that 500mm lens, just buy a 400, it's the same according to you. How do Nikon and Canon sell all those 500mm and 600mm lenses then if all you need is 400mm and it's just as good. You'd think long glass would be extinct by now.

These people don't agree, but hey whatever.


Who's to be believed here? Ian, or all these folks?

Don't go getting stupid on me here Ian. Especially in birding, you never have long enough and 400 is too short. 500 is barely adequate, a 600 ƒ4 with a 1.4 on it is quite nice.I know you like to "win" these discussions that that was pretty lame even for you.

Less than 10% of the wildlife photographs I have taken last 5 year was over 400mm on FF

take this one at 370mm, my regret with this photo is I should have went with 300m for better framing



One of my all time favorites was taken at 290mm on FF



There must be some inherent difficulty to shoot birds from bird feeds because you keep posting photographs as some testament to how hard they are to take, you might be right as I usually don't photograph wildlife around them.

And as far as winning these discussions, I know you can paint the snow yellow way more than I ever could, so you will winning these discussions is a given every time.

What I feel as really really lame is that everyone must photograph, use equipment, and think as how would Norm take this photograph. You must be right as you are the self appointed expert
I guess I'll have to start taking Bird photographs around the feeder to better understand you .
