Well deserved, great composition, timing, and exposure.

He has not been helping his reputation in the Canon APS-C forum here. Poor timing.

JackM: Mount a 70-200/2.8 to an APC-C camera and you have a 105-300/2.8 or 112-320/2.8 (not quite in terms of DOF, but in terms of shutter speed). This is hugely valuable for youth sports. Try to match that with Full Frame. The only way is with a Sigma 120-300/2.8, for $3600.

for $4000

Fair enough, but 36mp cropped to APS-C is 16mp. We are on to 20-24mp APS-C sensors now. That's significant for wildlife or any time you need more reach.

I tried a 1.4xTC III on my 5D3. AF performance took a nosedive.

The ISO difference between a 5D3 and a 7D2, for example, is less than 2 stops. More like 1 stop, if that. If I'm shooting indoor basketball at ISO 3200 or higher, FF at 12800 is going to look much worse. And a 70-200/2.8 has better AF.

No, I didn't, as you can see I mentioned DOF. You can keep your nerdy equivalence, I'll keep my 2 stops faster shutter speeds.

Also, 70 x 1.5 = 105. 70 x 1.6 = 112.

Funny how I carried my X100S all around Disney in my shorts pocket. I guess I imagined that.

I have a 5D3 and a 24-70, among other lenses. I also have an X100S. I'm just saying a 16-55 constant f/2.8 is going to eliminate the portability of the X-T1, and therefore the biggest real reason to "go mirrorless". I've also tried the EVF on my X100S, I simply don't like the look of it. I feel disconnected from the scene.

In reply to:

JackM: 5D3's AF is behind the times? LOL. I guess the 1DX's is too then.

All I've said is what ozturert said, but you seem to want to misinterpret more meaning where there is none, and then react to that. I did not say subject tracking was useless, and I did not suggest an alternative to not mention these things at all. You imagined that I did.

Pointing out that the 5D3 has no subject recognition/tracking would be fair. Calling the whole AF system behind the times is too much editorializing. The 5D3's AF is still remarkable and to be desired by anyone looking for a FF action camera. You make it sound like it's bad when it's not. Sure, for anyone without an investment in lenses, the D750 is probably the way to go for several reasons, namely price for one, and DR another. But the difference in AF systems is not a reason for a Canon shooter to consider switching, in the slightest.

Typical. I didn't say subject recognition and tracking was useless. I just think saying 5D3 AF is "behind the times" is misleading. Sure it's not bleeding edge, but it's still one of the best on the market. You make it sound like one would have to go to the 1DX in order to get good AF, and that's simply false.

Yet somehow my 5D3 took about 10000 keeper action shots of youth baseball and soccer players this year, and paid for itself, again.

So I guess 15 cross-type points out of 51 is state of the art, hmm.

I use my 5D3 when I'm worried about that stuff. But people need to get real, the pics were practically taken in a cave.
