Yup, great lens for the outsides. Pretty sharp even wide open, 135mm is long enough for "some" wildlife and AF is still fast enough for tracking dogs apparently

Fgaudet, you have an Australian Blue Heeler ... typically energetic specimen, too, from the shots!

Thanks for sharing the photos. You got some nice ones. It must be fun to shoot the frisbee dogs - I think I'd enjoy that.

Although I suppose it's strange for me to call it "fun," because as much as I like to shoot runners, it's also exhausting. I'm constantly changing the focus point, camera orientation, framing, and myriad other variables as each new runner or group of runners approaches. And then I do it again 2 seconds later for the next group.

As I mentioned, the DA*50-135 is one of my favorite lenses. But it's of little use in the above situation because it's seldom in focus, whereas the FA135 can do it:

When your aperture is f/3.5, the athletes fill the frame, and they're coming right at you full speed, focus accuracy is paramount. The DOF is so shallow it leaves little room for error, and the lens must constantly re-adjust in AF-C mode to remain in focus. If the subject is moving across the frame the focus barely changes, and if the aperture is f/8 you have so much DOF you can hardly miss. But this isn't using a lens to its potential, as I'm sure you know.

So while you can get certain types of action shots with this lens, I wouldn't want to mislead the OP if sports is a primary application for him.
Agreed. I'm sure that if I photographed runners as you do, I'd reach the same conclusion. Your runner images are very good, sharper than mine. As you point out, a subject moving across the frame is very different and that's most of my work.

Dance is a different problem set. To stop motion with constant stage lights, I need wide apertures and high ISO. My baseline exposure is f4 at 1/320 and ISO 3200 and I go up or down on ISO based on lighting cues and costumes. I'm constantly zooming and rotating 90 degrees. The 50-135 from rear of theater is a wonderful lens and I do use it at 2.8.

Unlike you, I have the luxury of learning choreography by watching rehearsals so I know when things are coming, who the dancer is and letting the music give me timing. Early on I started tracking dancers with the rear AF button and now it's the only way I can shoot. Even then, for any of a long list of reasons, I delete most of the images. And yes while I love it, it can be exhausting.

This was pretty bright with a highly reflective costume so at 135mm, it was f4, 1/320 and ISO1600. And as her Mom reminded me, she was hurt, one ankle was strained.

70mm, f4, 1/320, ISO 3200
