The discussion centers on the importance of mastering manual focus in photography, particularly when using fast lenses. The original poster shares their journey of learning to focus accurately, emphasizing the challenge of placing the plane of focus correctly, especially on moving subjects like birds and squirrels. They highlight a key technique of focusing on the subject's eye to achieve sharpness, noting that this often results in other parts of the subject, like the beak, being out of focus due to shallow depth of field. While acknowledging that autofocus simplifies the process, they advocate for manual focusing as it offers greater control and flexibility, allowing photographers to use more affordable lenses. Additionally, a suggestion is made to increase the f-stop to enhance depth of field, which could help in keeping more of the subject in focus. The discussion also expresses interest in the technical details of the shared bird shots, specifically the EXIF data.

I'd like to share this tip, regarding focusing.

Two of my three lenses are manual focus, so I've had to learn how to focus properly and quickly. When I first got my camera about 4 years ago, my lack of skill in focusing was obvious- at the time, I didn't appreciate how difficult it is to accurately place a plane of focus when using a fast lens, and I've made a few suggestions previously (smoke, fire) to get some practice focusing on objects that move quickly.

Now that the weather has finally warmed up, I've been practicing on birds, squirrels, etc. using my telephoto, and I wanted to share some results (these are all 1:1 crops).

The 'rule' is to place the plane of focus on an eyeball, like this:

Notice that the beak is already out of focus- the depth of field is less than a centimeter. Alternatively, if I 'break the rule' and focus on a nose, the eyes are blurred. This can be pleasing as well:

I suggest taking some time and working on your technique. Even though it's tricky and sometimes frustrating, when I 'hit' focus properly, the results are quite satisfying:

Sure, autofocus makes this much easier. But having the skill to manually focus will give you more flexibility and control when you are composing your shot. Plus, you can use cheaper lenses...

you could up the f-stop a bit and that will increase your DOF, resulting in more of the subject being in focus :)

would be interesting to see the EXIF data for those bird shots


cheers
