400 f2.8 for sure!

Mine does. I would love an aps-h sensor'd 1dx.

Definitely.

Yes, the 400 f/2.8 is awesome on both a crop and full frame.

I have no doubt that the 400mm is exceptional lens. But if 400mm is sufficient on a full frame for these sports, then 300mm should be sufficient on a 1.3 crop. And isn't the 300mm lighter by 3 lbs and cheaper by $4000?

Now that I am usually shooting with a 1dx, I spend more time with the 1.4x extender on the 400 when the light is good. Or when the light isn't so good, I am moving with the action more than before.

I recently re-acquired one of my old 1d iv's and may use that some outdoors during the day.

400mm f/2.8

out of curiosity since most are recommending the 400 2.8, for what situation would you recommend the 300?

the 300 2.8 is better for basketball. Otherwise, 400 all the way

Yup, smaller courts/fields. 300 would probably work well for Tennis too.

It's really hard to make the decision without testing out both lenses.
I started with a 300/2.8, moved up to a 400/2.8 & then moved back down to the 300mm.
I found the 400/2.8 too big & heavy for me, i preferred being able to handhold the 300/2.8 (this is for field sports - rugby,soccer etc.).
It also depends what level you'll be shooting. I can see why a 400/2.8 would be good for pro's as they often shoot night games and have limited capability to move around and get closer to the field.
Whereas if you're shooting amateur games a 300/2.8 could suffice as there are less restrictions, and day games are more common (meaning you could use a 1.4x TC).

But if price wasn't a factor, i'd choose the 400/2.8

thanks for the input. Alot of great advice
