    G9 + 100-400mm lens: Autofocus Locks on Background

    It would seem that Olympus must be aware of this problem since they allow you to customize the focus distance limits of the lens via their firmware. (At least with the E-M1 II and E-MX cameras.)

    Critters in YOUR Backyard....

    Literally just a few feet from our house, a Timber Rattlesnake paid a visit. We have them here is SE Minnesota. Photographed with the G9 + 100-400mm.

    G9 + 100-400mm lens: Autofocus Locks on Background

    Both G9 and the 100-400 are at Vers. 1.2. I believe this is the most current version. I have also seen a similar problem with Canon DSLR's but typically a second pump of the focus, it will snap in to focus. Thanks.

    G9 + 100-400mm lens: Autofocus Locks on Background

    That is really nice to know on both accounts. I really like the ergonomics of the G9 but this has me thinking. Thanks.

    G9 + 100-400mm lens: Autofocus Locks on Background

    There's no option for that. Good to know Oly has that. Maybe I might try an EM1 II, but will it work with the Panny 100-400mm?

    G9 + 100-400mm lens: Autofocus Locks on Background

    Ok. Thanks. Then it must be Panasonic's software/firmware that for whatever reason seems to overlook this situation. It's interesting that the problem has ported over to their FF cameras.

    G9 + 100-400mm lens: Autofocus Locks on Background

    Olympus is not CD, it has phase detect...at least on the EM1 II and now the EM1X.

    G9 + 100-400mm lens: Autofocus Locks on Background

    That's a good point but the G9 does not offer that feature and focus limiter on the 100-400mm lens is either Full or 5 meters to infinity. In either switch setting, the lens is allowed to go to infinity. If the lens had a third setting that allowed close focus to maybe 15 meters, that would...

    G9 + 100-400mm lens: Autofocus Locks on Background

    Here's a couple of shots taken just last night of a juvenile Eastern Bluebird showing how large the subject appears. It would not unlock from the background. I had to move my focus to the ground to obtain close-focus, then recompose the shot. Luckily, I had a patient subject waiting to eat...

    G9 + 100-400mm lens: Autofocus Locks on Background

    I just saw something here that leads me to believe this is a contrast-detect problem and has nothing to do with the 100-400mm lens nor the G9. I was watching a video from Kai W reviewing the Panasonic S1. In his video at the 6:24 mark, he describes almost the exact same problem using the S1...

    G9 + 100-400mm lens: Autofocus Locks on Background

    Thanks. Using manual focus is a work-around of sorts and does work as long as I have time to get it close to the foreground bird before it takes off. Still a bit time consuming however. Once the lens has gained near-focus, it does lock-on and hold focus. It's the initial focus that is the problem.

    G9 + 100-400mm lens: Autofocus Locks on Background

    I tried MF + AF as well as AF-S and it make no difference. It still cannot pick out the foreground subject. Thanks.

    G9 + 100-400mm lens: Autofocus Locks on Background

    Yes. I actually reduced the size of the one focus point as small as I could make it and it had no effect. Even though the one, small focal point clearly was only on the bird, it would never focus on the foreground bird. Good idea and one that I thought would work.

    G9 + 100-400mm lens: Autofocus Locks on Background

    I'm not talking about BIF settings. I am talking about initial focus of close subjects. They do not need to be in-flight. For example, a bird perched on a thin, metal fence post 30' away. Behind the fence post, there is a tree line. The camera is focused on the trees. Attempting to refocus on...

    G9 + 100-400mm lens: Autofocus Locks on Background

    I've had the combination of the G9 and 100-400 lens for over a year now. Currently at the latest firmware update as far as I know (v 1.2). I still run into a problem when photographing birds at close range...If the G9 grabs focus on the background, it is nearly impossible to refocus on the...

    PL 100-400 experiences and thoughts

    I have been doing bird photography for many years and looking at your test images you are definitely dealing with atmospheric heat waves. Especially with cool temperatures and a warm sun, heat waves can really mess up your images. Having the geese on the ground with direct overhead sun is...

    Long Telephoto Lens?

    Well...I guess I wait and hope that Metabones finally releases an adapter that will allow my Canon lenses to work the the GH3/GH4. They have been promising for YEARS that they are coming out with an adapter that will allow aperture control and image stabilization. I'd be happy with that I guess...

    Long Telephoto Lens?

    That's kinda what I was thinking and I'd really like to use it with the GH3 and with the GH4 once it is available. I wish we could get Panasonic to build a longer lens. Their 100-300 isn't enough. A nice 400mm lens would be great for bird photographers. 500mm would be optimum.

    Long Telephoto Lens?

    Thanks Oz, I have considered the Oly 300mm f2.8 but it's still too short. Is there a teleconverter that will work with that lens? Also, has anyone tried the Oly 300mm on a GH2/GH3? Cheers, Alan

    Long Telephoto Lens?

    Hi, I'm new to the forum, but I've been in the photography business for many years. I primarily do bird photography/videography and use Canon equipment for my photography work and use a GH3 for video. Typically for birds I'm at 840mm (600mm +1.4x TC). Yes, I realize M43 "effectively" doubles...
