Check your firmware versions for body and lens. Lumix just updated firmware for the G9 on 11/18/2019. Be sure you install it if you haven’t.

Go here and get an eyeful from a pro who uses your gear (and more).

I like the G9/100-400 combo, but haven’t really used it for BIF. I just did the firmware upgrade and I’m looking forward to trying it out. Also looking forward to testing out my new Wimberly MonoGimbal head.

There is a problem with all auto focus lenses, that is what they focus on, especially where the scene is ambiguous. When it comes down to it, it is the photographers job to determine where the point of focus is and that means using manual focus on those occasions when auto gets it wrong. Back to the old days, I know it is not easy and takes practice. I have a full kit of canon FD lenses I am now able to use since I bought a Sony A7, getting back into real photography again. You can do it.


The problem is not so much with the auto focus as with the photographers who don't know how best to use it. I think spot or single area, and locking focus with a half press is a good option for something like BIF - or perhaps focus tracking.

You both really missed the point. You clearly don’t shoot BIF.

I have yet to be convinced that any mirrorless camera can capture bif as well as a DSLR. The D500 armed with the right lens is an exceptional example for bif photography. If someone could show me a mirrorless camera that could perform as well as the D500 for bif I would buy it tomorrow.

As I said on page 1 "In the D500, you probably already had the best-for-purpose birding camera ever." and I am not a birder, and I am a died in the wool M43 shooter.

You are correct - I don't, but I'd love to know what "the point" is?

The poster you responded to blamed autofocus in general. Manual focus will not improve your keeper rate with BIF. You blamed people for not knowing their autofocus systems and gave bad advice on which settings to use.

I did not suggest using manual focus - autofocus can be locked by half pressing the shutter button. The only other suggestion I made was to try focus tracking. My suggestions were simply suggestions - and not offered as advice. As a non - birder I would not presume to offer advice on birding, which I recognise as a specialist branch of photography.
As an aspiring birder,what positive advice would you give the OP?

The post you quoted suggested manual focus. Tracking was the one thing that is right. You don’t want single spot, you want group. And you don’t want the half shutter press lock. You want to remove focus control from the shutter button and use back button focus. That’s the general info, but that’s not what the OP was about. The OP was referring to a particular body/lens combo, the G9 with the 100-400mm zoom. I both and it’s a great combo, just not great at BIF. I also have the D500 with the Tamron 150-600. That is great for BIF. I’m hopeful that the focus improvements in the firmware update for the G9 will get it close. I’ll find out next time I shoot birds.

It would seem to me that spot focus for a bird in a tree would be as good as anything else. For me half press shutter locking is better than on/off back button, depending on camera probably needing two fingers.
However, there are more than enough photographers capturing birds without me joining in. Not that my present kit would do it.

BIF indicates that the bird won’t be sitting in a tree. And I’m not going to go into a treatise on why BBF is better for BIF. There’s already a treasure trove of info out there.

If you have this combo; I do mostly bird photog. Used Nikon D500 with Nikon 200-500 lens for three years. thousands of birds ( still and flying) with high hit rate. But trying the Pana G9 with their 100-400 lens, having nothing but trouble with both still and flying birds. Focus will not hold (no matter which type of focus used). On stills, if subject is in grass or trees, focus will hit background or nothing. Fluing birds - focus is terrible, about a 5% hit rate. On my Nikon setup hit rate is about 70-80% and I have trouble deciding which to discard. Internet has a few comments about this problem. Any answers?

After what you just said, I find it strange that you're having trouble deciding. To me that's a no brainer, stick to what has proven to you to be working!
