Dogs and Ultrasonic Motors

A few weeks back, after saving money for a couple months, I bought a 50mm f/1.4 lens. It was my new baby! However, it did come with one suprise.

It was a Saturday when it arrived. R had gone to the White Sox game with my brother, so it was just me and our dog Marty at home. Marty has always been my best subject, so I didn’t hesistate to try out my new lens with him while R was away.

He was laying down on the floor of our living room. I snuck up and got down onto the ground. Then pressed the shutter button halfway to autofocus. Marty got up and ran to the other side of the room. So I went over there, tried to get him to lie down or do something cute or interesting. Just when I thought I was going to get the shot, I autofocused and, yet again, Marty ran away. Now, I was getting frustrated. This went on for about five minutes, to the point where I was “raising my voice” at him, telling him to stay. Finally, I got a decent shot off and decided to leave him alone. I figured he just wasn’t feeling photogenic.

But then, the poor dog stood in our kitchen, tail between his legs, head lowered, body shaking. I couldn’t figure out what was wrong. He stood that way for the next 15 minutes. I took him outside to do his business to see if that was the issue–nope!

To make a long story short, I figured out that it was the ultrasonic autofocusing motor that was causing him to run away and shake uncontrollably. His big beagle ears apparently can’t take the sound. I felt so bad, but also super dissapointed. I conceded that whenever I was taking pictures of Marty or he was in the vicinity when snapping shots, I had to manual focus, something that I hadn’t been very comfortable with. Every now and then I have it set on autofocus and forget to change it. Sure enough, it sends Marty running away to a corner, shaking. The poor thing.

Needless to say, the past couple weeks I’ve manually focused more than I ever have since getting my camera.  I suppose it’s good practice for getting comfortable with manually focusing (or at least I tell myself that).

Has anyone else had this issue with USMs and their dogs running away in fear and pain?

Pretty nice post. I just stumbled upon your blog and wanted to say that I have really enjoyed browsing your blog posts. In any case I’ll be subscribing to your feed and I hope you write again soon!

Thanks so much for stopping by :-) . I’ll definitely write again soon! I’m trying to do a post a day, but we’ll see how long I can keep up with that pace.

When I brought home my dog, I took a few pictures of her and used an Ultrasonic (85mm). She was terrified! She eventually got over it though, and is used to me taking many many pictures of her. Of course, she’s a cairn terrier/pug mix and her hearing is probably not as sensitive as your dog’s!

Glad to know that it’s not just my dog. I’ll keep my fingers crossed that he will get used to noise and I’ll once again be able to take quick shots of him. Manually focusing on a constantly moving creature has been a challenge!
