GFX 100S II "Performance Boost"

[mujana]

I received my GFX 100S II this last week and have completed most all of my setup and customization.

There are six Performance Boost modes and the Fuji manual has no specific information quantifying what they really do, other than a general description. Can anyone, here, provide any further performance information or advice concerning these modes?

Thanks!

Also, I like this camera more than I thought I would. I knew I would love the output files, but didn't expect to like the camera as much as I do! The only thing I did not like is the lack of battery charger, which I just remedied, ordering a dual battery charger. The camera gets hot charging the batteries, internally - video shooters must really like that, starting off with an already hot camera.

Does page 367 in the GFX100II manual answer your question?

I have always assumed that if I had it on, it would improve my image fidelity to soar even higher beyond the norm of FF....

It is always on, and I have no clue what it is.

What does the manual say? I have never in 5 years ever once looked at a Fuji manual.

If you do not read the manual of a complex camera like Fuji or at least study Rico's book, you are probably using your camera below its capabilities.

I'm kidding.. There is not much about that camera I'm not very familiar with.

BTW, Rico writes that Boost mode helps AF-C.

It should help AF, when “boost” is set to AF priority, I guess.

I did a bunch of testing on this when I got my GFX100S and also didn’t find a huge difference except in edge cases. Think of the boost or performance mode as how many image samples you want to provide to the two sub-systems: 1. Autofocus and 2. EVF.

Your setting helps tell the camera where to prioritize sending the most image samples to. If you choose AF priority, the camera gives the AF system more image samples to work with. If you choose EVF, it gives more sample to the EVF for a smoother viewing experience.

I’m not clear on what the AF low light priority does but it’s likely similar, in that it gives more samples and perhaps does some image processing to boost the brightness before the AF system does its work.

In practical usage, I was only able to discern a difference in EVF refresh rate, less smearing and the AF low light. The AF priority mode didn’t seem to make any difference. There’s likely something else in the AF pipeline that’s a bottleneck.

This video provides some good insight from Fujifilm:

I’ve never been able to see any difference. I thought all it did was increase the EVF refresh rate.

Here is what I think, and I have thought this for years.... This Fuji performance boost stuff is a bunch of nonsense.

However, if I ever decide to shoot a moving subject and use any type of AF C focus tracking or subject detection, I'll turn on AF Performance Boost just in case.

But what illogical nonsense! GFX gets criticized for focus tracking and they want you to turn on another setting to make it work better? Crazy. It should always be maxed out when you use AF C if any type.

Are they doing all of this crappola to save battery life? Crazy! That is what extra batteries are in the bag for.

I never mind changing a battery.

Who wants to diminish any type of performance to keep from carrying an extra battery?

And that stupid Fuji video Farz posted? I saw that years ago and that Fuji guy talked to us like we are morons - equating the power saving features to our human bodies for half the video so that we could understand it.

The "standard" setting seems to be there, to get higher number of images on a single battery charge, according to CIPA ratings. The higher, the better ofcourse;-).

Advertises well.

The difference in battery use is considerable, and it would be bad PR if their battery consumption were much lower than the competition or if somehow AF-C would consume more battery.

A brave move would be removing the Boost option and many other unnecessary options. However, only Leica dares to remove stuff and can survive the indignation.

Hassy, too.

Porsche has figured out how to get the user to pay for leaving stuff out, which is a neat trick.

Informative! So, do you keep the camera in boost mode (AF)?

I keep it in AF-Priority mode because Fujifilm AF needs all the help it can get Since I rarely run out of battery, I don't mind using up some of the stored energy to "help" the AF sub-system. It's very hard to conduct repeatable testing of the AF-C system, but I subjectively feel that it's stickier in AF-Priority mode, but I don't have objective evidence to prove it.

By the way…I like your website!

Many thanks! I came very, very close to shutting it down this year. Google made an algo change in March that reduced traffic by 80% overnight. Since it’s a hobby blog, the fulfillment comes from reader interaction.

With nobody finding the site, it got a bit boring. Thankfully, I stuck it out and Google put a new algo out a few days ago which has returned some of that lost traffic. I’m now getting comments posted and messages from readers again.

What does this mean?



When they say "monitor" do they mean the rear tilt screen, the EVF, or both? This statement would seem to imply that BOOST - AF PRIORITY is always on while focusing.

I think I read that sentence four times and was still shaking my head.

Where did you get that screenshot from? In the GFX100 II (p367) and GFX100S II (p340) manuals, it says the following, which is clear:

Don’t shut it down. I find it informative and well written in understandable language!

They both say the same thing. Are you able to answer my question about what they mean by "monitor"?

My version differentiates between AF Priority Normal and Low Light, while your version does not make sense. Where did you get it? The term "monitor" is used throughout the manual for the rear LCD:

So AF-Priority Normal only works when using the rear LCD screen and not the EVF? That seems super strange.

I am now officially confused and have no idea how any of that weird power boost mode stuff works. I thought I did until this thread....

Ditto. The options are very confusing.
