lens-accessories Auto Focus Important Guide

I got this set for a gift and I’m fairly well pleased. You really can take some great close ups and capture incredible detail. My only complaints are that it feels cheap and that the auto-focus is hit or miss.

When I say it feels cheap, I mean that it’s very light-weight, clearly plastic, and you can hear parts rattle a bit. The fit to the lens and the camera body isn’t as smooth as I’d like. I often feel like something’s going to snap as I try to align the tubes with each other or with the camera/lens. I also don’t have a ton of confidence that my 200mm lens is entirely safe when I have more than the smallest tube on. I definitely take the them off if I’m going to move from one spot to another. Even the little bounce from walking around seems like it might be too much for the plastic on this set to handle. The last thing I want is for my expensive lens to fall off because it’s too heavy for the extension tubes to support. There’s definitely some sag when I have a long lens and all three sections of the set on.

Speaking of having all three sections on… if you do, forget about auto-focus. With one section on, you can get it to autofocus about 1/3 of the time. With two sections on, it’s about 1/8 or so, and with all three, it’s virtually never. I know that the depth of focus is very narrow, so you have to have the distance between you and your subject just right, but I still can rarely get the autofocus to work, even if I use a tripod and keep everything just so…

Still, I’ve taken some great shots, and my expectations weren’t super high, so I’m pleased.
