SUMMARY

This discussion focuses on mastering manual camera focusing techniques, particularly for wildlife photography using telephoto lenses. The key advice is to aim the plane of focus on the subject's eyeball to achieve sharp results, as demonstrated through 1:1 crop examples. The importance of practicing with fast lenses and understanding depth of field (DOF) is emphasized, along with the benefits of manual focus over autofocus for greater control and flexibility in composition.

PREREQUISITES
  • Understanding of manual focus techniques
  • Familiarity with depth of field (DOF) concepts
  • Experience with telephoto lenses
  • Basic knowledge of camera settings, including f-stop adjustments
NEXT STEPS
  • Research advanced manual focusing techniques for wildlife photography
  • Learn about depth of field calculations and how to manipulate f-stop settings
  • Explore the use of telephoto lenses for different types of subjects
  • Investigate the significance of EXIF data in evaluating photographic techniques
USEFUL FOR

Photographers, especially wildlife enthusiasts and those interested in improving their manual focusing skills, will benefit from this discussion.

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
