AF-finetune for Subject and Shot - how to get better focus for birds in flight (towards the camera)



I use the AF-finetune to calibrate my lenses and cameras.  Usually this works out pretty well.  Calibration will set the camera to not front-focus or back-focus, the focus will land where you want it - on the spot where focus was attained.

What I have found almost all the time when shooting birds in flight is that focus is harder.  Sure, nothing news worthy there.

But what is most frustrating is when a bird is flying at the camera focus is rarely on the eye.  And it is because the eye is rarely in the center of the frame where the selected focus point is most likely to be.

I've speculated and toyed with changing my AF-finetune specifically to be setup for this type of bird flight shot, but it is rare that I do it.  The setup is to change focus to bias towards front-focus.  With the birds flying at the camera, and the head likely the closest part of the bird, you want focus to be closer than what you will normally get.

So, I rarely do it because how many flight shots towards the camera in a row do you get and if it is just a few is it worth blowing all the other shots?

On this day I was shooting the Herons as they were nest building and they kept flying a similar route.

I got some of the best focus in this setup than I have ever gotten before...  Normally my lens (600mm f/4) is set to about -14AF I think, and I changed it to -18.  I tried a few settings, and the following weekend I tried with my 500mm and experimented more.  I got better results with the 600mm at about -4 on top of my normal calibration.

Have you ever tried this technique?

Or are you already happy with your birds in flight towards the camera shots - so no need to tweak this setting?

Kenilworth Aquatic Gardens Summer 2016

Over the last 8 years I've been to Kenilworth Aquatic Gardens a bunch of times, mostly looking for the Yellow Crowned Night Herons. But also other birds and the great Lotus flowers and water lilies.

This year there weren't any YCNH's that I spotted, so I photographed the Lotus a *lot*.

Sometimes the petals would fall off quickly, in a sort of chain reaction once the first one broke free. I'd never seen that before, it was cool.

The YCNH's were great in 2008. I went multiple times and got some close ups and some feeding photos...

The second to last time I went this year I shot the water lilies in the back, and the light was pretty good. I used a 600mm lens, which I would normally use for birds, and I shot the flowers...

Water Lilies @ KAG

Just prior to this visit I had gone to Kenilworth Aquatic Gardens I think 5 times, and the first few times I took a normal approach and shot the flowers with a long lens, and had hoped to see birds, but still shot the flowers. The images I got were "normal" and looked ok. I was happy with them at the time. But they were like many other images I've taken and seen others take. This one with the Red-Winged Black Bird was a highlight. The birds were in the flowers and I could shoot them for just a few minutes before they flew off.


So this year on visits 4 and 5, I brought some macro gear and shot much closer images of the flowers and got much different and I think better results.







As I reflect on the half a dozen-ish visit I've made to KAG before this year, and then the 6 or 7 visits I made this year I noticed how it took a few visits to shoot through the shots and approach I had in my head already. It took that long to then be able to try to think differently, to see the gardens and flowers differently and to get different images.

On the last few visits I still brought a long lens (600mm) but I also brought a 70-200mm f/2.8 and a 24-120mm f/4 lens, along with the Canon 500D closeup filter for a 77mm lens ring. By using that filter I was able to turn both lenses in to very close focusing lenses that gave drastically different shooting distances and super narrow depth of field.

I'm happy with the results I got this year. It took a bunch of visits to get lucky with the RWBB and then to start to see and shoot the flowers in a new way. In the future I guess I hope to be able to push past what I had planned and the way I was seeing things initially, and start to see in a fresher/different way like I did on visits 4 and 5 with the macro shots.

I've been meditating and practicing mindfulness this year and last year, and as I read what I just wrote above, I think that is a result of this new approach to life. It's all too easy to have a plan, work towards a plan, and then either execute on the plan and be happy, or not execute on the plan and be disappointed. But with a fresh approach and fewer expectations, and a more flexible nature new and unexpected things can happen.

Cape May NJ 2016 - Juv. Osprey Fishing

During the Fall I love to go to Cape May New Jersey. The raptor/bird migration is great. My friend Wayne turned me on to the location a while back, and I've gone every year since.

This year I have been once so far on September 24-25 (2016). It was a little early for big numbers of hawks, and the weather was not great for it either.

The best setup for hawk migration is when a cold front moves through, pushing birds east, and the prevailing winds are out of the Northwest. This pattern pushes birds towards the east coast and the way Cape May and the Delaware Bay are the birds run out of land to fly over, since there's water everywhere else and they tend to stop over on the cape.

But it's Fall and it's Cape May so not great here still has the potential to be good.

On this morning there were a few young osprey flying around over The Meadows and along the shore, over the Atlantic Ocean just at the edge of the beach.

The young osprey aren't very skilled at hunting yet and it takes them a lot of effort to catch fish. Here the osprey has caught 2 small fish, after trying numerous times to get something. I also saw dolphins in this same area and they were hunting as well. I probably saw more than a dozen of the dolphins over the course of a couple of hours.

The ideal time to see hawks migrating is when the weather is right, and during the first couple of weeks in October based on my experience...
