Re: Macro focusing.

I normally focus on it.

For example - If I photo some bug - I normally aim to get the eye in focus. So I aim at that. Greater F stops will allow more DOF slightly to front and more to rear as normal, but I always aim for the point I want.

If you're using a tripod setup, then if you have LiveView you can get a rough idea of the focus. Otherwise shoot and check the results. Don't forget if you're hand-holding then a small movement in taking the shot may move the focus.

Post some images and we might be able to see where you're going wrong.

Re: Macro focusing.

Yup, as Chris says, focus on where you want the sharpest focius - for bugs that's usually the eye

Depending on the aperture, the DOF will then determine how much (or how little!) is then in focus

Here's an example where you can actually see the line of focus running across the wood, crossing the wasp on it's head (should've been a touch deeper to get the whole head in focus! )

Re: Macro focusing.

Another shot of another wasp (a queen European Wasp this time) with the same line of focus. As the front of the wasp's head is aligned with the plane of focus, there appears to be more DOF but there's actually less!

Re: Macro focusing.

As far as I recall, focus does not start exactly where you fix it at. With big apertures it grows farther away and also nearer to the camera (I don't remember exactly by how much on each side). According to this, it makes more sense not to focus exactly on the point you want, but a tad farther away. Hopefully someone who knows this exactly will post and give more precision to the statement.

Re: Macro focusing.

Focus will be where you focus!

But it will extend for a third of it's distance in front and two thirds behind. So if the macro "in focus" was 9mm then it would extend 3mm in front of focus point and 6mm behind - if you see what I mean! So yes, if you wanted to get a whole flower in sharp focus, you might focus 1/3rd of the way into the flower!

Yes indeed; I was talking about where focus starts.
