In my previous manual focus post I discussed nine reasons to use manual focus. But wait, isn't manual focus slow and inaccurate? Not if you do it correctly.
In this post I will describe six ways to get the perfect (and fastest) manual focus. As will all things photography, practice makes perfect - You may not have your first manual focus pictures right, but as you keep practicing, you'll get better and better, until manual focus becomes a second nature to you.

This is by far the easiest method of them all. If you can measure the distance from the camera to your subject, you can use the Lens's focus ring to manually set focus to that distance.
This method works best if your camera is set on a tripod and your subject is still. It is also great for indoor photography, old lenses that have great focus ring scale printed and close subjects. It does not work well in landscape photography, unless you can run very fast and have a very long piece of string. [image CC by young Young Einstein]
If you look at the view finder, you'll find a small little circle with two small arrows. (My good old Nikon D70 has it on the lower left side of the "view finder strip".
Even when you focus manually, the in-focus indicator will let you know that you are in focus. Sweet, no?
If it does not work, you can try this trick. It is reported to work well.
One of the reasons a lot of photographers are not even trying manual focus is because it is very hard to even see if you are "really" in focus or just almost in focus.
Most modern view finders are dim (at least compared to older "non D" SLRs. To add insult to injury, most modern viewfinders are small. The solution to the viewfinder problem is a focusing screen.
A focusing screen helps you verify that you are in focus. Either by having a split image (see picture on left) that unites only when you are in focus, or by making anything that is not in focus really, really diffused.
Sadly focusing screens are becoming more and more rare nowadays.

If you know what you are going to photograph and you know where it is going to be, you can take advantage on this fact.
You can do one of two things: use a model to stand in and set the focus manually or focus to something very close to where you actually want to focus - for example the pavement on which the model will stand. [image CC by AHMED. (Busy)]
This one is especially effective when shooting landscape, stars or fireworks.
In those cases you can just move to manual focus and set your focus to infinity. If your landscape is indeed far away, it will be in focus. This is because things that are far off can be considered as infinity for any practical reason. [image CC by Timothy K Hamilton]
This method is extremely useful when you have a cluttered scene. You can use the camera autofocus
system to get you in the general focusing zone and then switch to
manual focus and fine tune to a specific point on the scene.
One of the common pitfalls of photographers who use manual focus is that once shooting session is over, they forget to go back to autofocus. This can have an artistic devastating effect on that session.
If you are in the habit of shooting manual focus, make it a habit to change back to autofocus at the end of each session. And also make it a habit to check your focus mode at the beginning of each session.

These tips are awesome -
These tips are awesome - right on point. Love the photos accompanied with the post as well!
very interesting
just read both pages about manual focus :
thank you ; very interesting
makes you feel at ease...
Beware of focusing screen
Just a word about focusing screen :
I've installed one on my Pentax K100D, and experienced exposure problems : sometimes, even whith autofocus lenses or manua focus lenses, when the f/stop is too big (as 5.6 for example), shoots were under-exposed of about 1 stop to 1.5 stops !!!
This was too anoying for me, so I removed this focus screen, since it seemed to be uncompatible with my camera :)
(PS : seen on some forums that the light measurement is done -after- the focus screen, so if the screen diffracts light rays the wrong way, this can cause troubles to light measurement...)
focusing screens
It looks like this is a dying accessory. Old film cameras were coming with split focus screen right out of the factory - even amateur one's. Later, you could buy an install a split focusing screen if you had a high end SLR. now you can not get them at all. sad.
As a result, I think that manufacturers decided to make their cameras less compatible (or invest less in verifying compatibility) with other manufacturer's focusing screens.
Sad.
focusing screen (split prism)
Here's the hot ticket for that:

Hyperfocal distance: not infinity!
ExpoAperture
is the slide-rule you want,
and once you know how good it is,
to be able to *decide* exactly what's going to be in focus,
then the rest all falls into place.
:)
5. Set to Infinity
Great articles!
This tip could be enhanced by explaining how to make use of the depth of field (higher f number means the subject will be in focus over a greater range) and hyperfocal distance.
Hyper focal
I totally agree. In the first article in the manual focus series there are two great references for learning hyper focal:
- Hyper Focal Distance - term
- Hyper Focal Distance tutorial- doing it
