Lumix GH5-GH5S-G9 Autofocus Guidebook

Lumix GH5-GH5S-G9 Autofocus Guidebook

Gloriosky… as my dear mother likes to say. Panasonic just released a desperately needed Lumix GH5-GH5S-G9 Autofocus Guidebook and you can download the guidebook here.  When LUMIX introduced the GH5, G9, and GH5S, they updated each camera’s menu to include new Custom AF settings. When I became aware of these changes, I was less than enthusiastic due to lots of experience with our  NE Explorers shooting Canon cameras.

Canon started this menu filled maze of autofocus options that are seemingly impossible to figure out. Nikon’s AF menu had one option “Focus Tracking with Lock On” which was very simple, offering AF1 (Short) – AF5 (Long). It was pretty easy and thankfully it typically just worked.

Panasonic should be commended for publishing this new document to help us all achieve better results when using AF-C which is the same as what I refer to as Predictive Autofocus. Fast and accurate AF-C is essential for those who want to shoot sports, race cars, birds in flight, running horses, and lots of other exciting subjects. Things that nature, outdoor, and sports photographers love to shoot.

Action photography for me is a passion and something that is very difficult for even the best photographers. Moving in sync with your subject takes skill, athletic ability, confidence, and coordination. Not everybody can follow a fast moving subject. Those that can have a built-in advantage as long as the camera they’re using can also keep up. If it can’t, your skills as a photographer make no difference.

Back when publishers would pay for quality photography action, pictures could demand a larger payday. The cover image for one of the stories I did for National Geographic is a good example. A great gray owl in flight is captivating, exciting, and pulls people in to read the rest of the magazine. Great AF-C is not just a nice to have, it’s an absolute need to have. And I’m hopeful the recently released AF manual will improve the predictive AF we have in our LUMIX cameras.

I’ll be writing a lot more about the AF-C settings in the G9 in a soon to be finished G9 review. Stay tuned for a lot more input on this very essential feature.

P.S. Even soccer moms want great Predictive AF.

    This is a much more mundane question about auto focus on the G9: I was taking photos with my new Lumix 100-300mm of December’s full “Cold Moon” this morning. I had a heck of a time getting a good focus either in manual or auto. This is obviously a big, stationary subject, but focus was a real bear. Any ideas, technically speaking, on what I was experiencing here with this problem? Thanks.

      Christopher, I need more info like,

      1). what AF pattern were you using?
      2). did you have a polarizer on?
      3). were you on tripod?
      4). were you on AF-C or AF-S?
      5). were you placing the moon in the center of the EVF?
      6). was the AF sensor (which ever one you used) squarely on the moon?

      Get me some more info and I may be able to help.

    Dan – I called the shop in Boseman. I don’t know who it was that answered.

    Thanks very much for the information. Which of the teleconverters would be the most useful? I assume the 1.4 would result in sharper images?

      Yes, the 1.4x teleconverter will give the most premium results but the 2X is also very good.

    Dan, I am not clear on the use of the teleconverters with the 50 – 200 lens. I was told by a camera person at one of the companies that they would only work with the 200 lens.

    Thanks for your help.

      Hi Dorothy, the information you received regarding the teleconverters only working with the 200mm lens is INCORRECT. In fact, the new 1.4X and 2X teleconverters actually work with two lenses, the new Leica 50-200mm, and the Leica 200mm. They don’t work with the 100-400mm. They did that on purpose since you wouldn’t want to use either teleconverter on that lens. Adding the additional glass of either teleconverter would seriously degrade image quality and you would not be happy with our pictures. You mention that you were told this false information by “a camera person at one of the companies”. Can you be more specific. Was this a salesperson behind a camera store counter, a Lumix rep, which company are you referring to?

    I went through the manual but the one thing that is missing is that AF Custom settings is not assignable to a button so you need to go through menus to change it, at least on the G9

    Is anyone at Panasonic actually using the cameras or are they just creating features?

    Dan, I’m going down to the Everglades this month and in the process I’m giving my Olympus 45-150mm (with the teleconverter) to my friend down there who has my old GH-4. I have the 100-400mm but I’ve been eying the 50-200mm and the 200mm as a possible replacement. Without showing your cards (your reviews forthcoming) of those two lenses, above, would you have a preference of one above the other if it came down to nature shooting when you always have a camera hanging off of each shoulder?

  6. Alan StankevitzOn Sep. 26th, 2018 (5 months ago)

    Curious as to why you would leave the 100-400 home? Is the autofocus better with the 200mm even with the 2x? I’ve seen a comparison video and the sharpness is better on the 200mm with the 2x but it’s really, really close. What is your opinion?

      Alan, I’m just in the process of doing some tests with the 200mm and teleconverters. It does seem very sharp, even with the 2X but more importantly, I just don’t need the reach of 800mm on this coming trip. Plus I want to do more work with the 200mm to get additional results to review.I’m hoping a review will be coming by the end of November. Stay tuned and let me know if you have any further questions. Thanks for joining the conversation.

    Thank you for your prompt response!!

  8. douglas smithOn Sep. 23rd, 2018 (5 months ago)

    Dan thanks for the information on the guide. Have you done a review on the Leica 200 mm F2.8 lens?

      Daniel J. CoxOn Sep. 23rd, 2018 (5 months ago)

      Doug, I apologize for not getting a review out on the 200mm yet. It’s been a busy summer. I’m hoping to get to it before December 1. I can tell you that I’ve fallen in love with that lens and will be leaving my 100-400mm home on my coming grips to the Canadian Rockies and Madagascar. I plan to take the new 50-200mm and the new 200mm, using them both with either the 1.4x and 2x teleconvrters. Both new lenses are that good. Thanks for your patience. I’m going to get to it.
