When I got my D300 and the Tamron 17-50/2.8 VC back from repair, I was really awed by the raw speed of focusing and the enormous precision of the autofocus.

Try that one time: use manual focus for a few days, and preferrably do that with a manual focus lens. I have two of them now, the 50/1.2 and the 24/2.8, and both feel so enormously better when focusing than any modern AF lens, it’s a pleasure to use them. Try using such lenses for a few days, then switch to a decent AF lens and feel the awe 😀

But then, oh my, am I slow focusing manually! On the other hand, this is part of the appeal of these lenses. They slow me down. I wouldn’t use them for action, but for subjects like today’s, there is nothing wrong with them.

  1. The speed of the focus depends what kind of focusing screen you have. Most AF cameras have matte screens without split image focusing. It’s hard to do any kind of fast, quality focusing with that.

    • Uhmmmm … well, … , there’s also this green dot … … … duck and away 🙂

    • No, really, that’s exactly what I do. Focusing manually on a DX viewfinder at 50/1.2, that would be insane. Well, I guess even a D3 wouldn’t make much of a difference, and actually that green dot works surprisingly well. Direction indicators like on the D3 and D700 would be even better, but if you know your lens, the dot alone suffices. It’s only not fast 🙂
