Re: Unless there’s motion, don’t use AI SERVO.

Like I already said, I never take the lens off f2.8. It is shot wide open all the time. My favorite lens for baseball is my 300mm f2.8.  When I do switch to my 70-200 it is a t f2.8 all the time, too.

 

What camera did you say you were using?

 

I  also have never used the DOF button for anything. Not even DOF !  There is plenty of DOF from the first base side line pit.  Even more if you are in the stands.

EOS 1DX and 1D Mk IV and several lenses!

Re: Unless there’s motion, don’t use AI SERVO.

Unless you have the top of the line 1-Series I don't think the viewfinders are good enough to really use DOF preview. It just gets dark. 8^)

 

But it does work in LiveView which might actually be helpful.

"While I do use f/2.8 a lot, and f/4 when I put on the 1.4x extender, I think I'll play with f/5 - 5.6 when I'm framing just the batter.  I'd like to get the catcher a bit sharper.  Although my app for DOF says at 110 ft, f/2.8, and 200mm, that the DOF is 9.3 ft.  Doesn't that mean that if the catcher's plane is less than 9 ft. from the plane of the batter, focusing on the batter should result in the catcher being in-focus?" 

 

I'd say your DOF app pretty much agrees with mine.  Without knowing your shooting location, I have no answer for you about capturing both the batter and the catcher in focus. DOF is pretty subjective, though.  It really depends upon what you consider to be acceptable focus. 

 

Your lens could also have a slight back focus, or front focus, issue, too.  I have used "Dot Tune" on all of my telephoto zooms, and the results have been excellent. 

 

The shot below of a play at thrid base was at 400mm, f6.3, and shot from 30 feet outside of first base.  My calculator says 14 feet, which looks to be just about what I see of the ground in this shot.

But, if you accurately know your distances, then your DOF app should be a good guide.

Re: Unless there’s motion, don’t use AI SERVO.

I don't know who's asking what questions of whom....

 

I'm using a 7D MKII.  I've reassigned the DOF button to switch between wherever the focus point(s) has been moved to, and the center.  I hit it with my right pinkie - and you're right, as a DOF preview, it's worthless.

 

I'm going to do the Dot Tune - thanks.

 

If I can get them to load, these two shots would not have been possible without 10 fps.

Nice shots.  Plus it looks like you know about good composition. Composition is a key aspect of a good photography.  Some don't.

Thanks!

 

FWIW - Using Dot Tune, my 70-200 also comes up needing ZERO adjustment!  Smiley Tongue

You do realize that I had already posted the fact that the shot I posted has been cropped.  Don't you?  Or, have you forgotten?
