Question to X100T owners

[Przemek]

I just ordered a used X100T on ebay and in aperture priority it behaves somehow odd - at least it's what i think.

When moving between high contrast scenes, the camera needs considerable time to adjust. This manifests itself with the aperture blades moving through their range step by step wise. This take a few seconds to adjust to the new scene. Aperture moving in aperture mode is strange in itself.
This problem is not present with the camera set in full auto mode nor in shutter speed priority.

I made a movie showing this issue

Anyone having the same thing?😕

Normal operation for mirrorless.

I haven't noticed this - I'm often in aperture priority

Why would the camera need to cycle through apertures if the aperture is fixed at a value?

Could it be shutter priority mode?

This is normal behavior to optimize the image in the EVF and the LCD. As the camera is switched on, the camera's CPU selects an aperture value in an attempt to immediately offer a usable EVF image. This is a first approximation and chances are that the initially displayed EVF image is discernible albeit not perfect. Then, the camera starts to measure the environment's actual brightness and will adjust the aperture to the optimum value so that only a minimum of image adjustment need be done electronically. Any electronic image adjustment will quickly impact the quality of the LCD image with blown-out areas or color noise.

I have a Ricoh GR and it doesn't do anything like that. Everything is fast and smooth.

I'm also wondering why it's only in aperture priority and yes I'm sure it's AP mode. Aperture ring set between f2-16, shutter dial on auto.

If this is normal, why does the camera behave differently in other modes? There operation resembles that of my GR.

It should do this in all exposure modes

 

[borge]

It's normal. It stops down gradually to find the correct exposure for the scene.

I have the original x100(first release) and shoot often in Aperture mode and it does not operate as you described "needs considerable time to adjust". Check your metering mode, I do notice that in a high contrast setting and the camera is set to spot metering the aperture is busy adjusting BUT it does not need "considerable" time to adjust. Its in split seconds. If its in a spot meter mode- switch to average or multi. Last, being you have a x100T, thus 2 new versions newer, it should be faster in all respects to mine. Worse case go to a local camera store and ask, they may be friendly and will help you diagnose even though you didn't buy it from them. It may be faulty? good luck- let us know. D

As noted, it is in Av, it shouldn't search for an aperture value. There must be some setting somewhere that is defeating the Av setting.

 

[splitimageview]

It's normal.

Those of you who remember the 35/1.4 Fujinon with the X-Pro1 at release, and the furor over 'aperture chatter.' Fuji ended up releasing new firmware that changed this behavior to reduce the noise level.

Google the phrase for more background.

You may want to go through and check all settings... I normally use the optical finder only, so I don't really notice this.

One thing I have experienced when using ND Graduated filters is "exposure shift". With the camera set to full manual mode, including fixed ISO, the exposure of the shadow area changes as I alter the strength and location of the ND Grads... my only 'guess' is the Dynamic Range setting (??) -or- because I shoot only in-camera JPG. The documentation is poor...

I really like the X100T and will not give it up ; )

 

[Darthfeeble]

This might sound silly but you aren't putting the aperture control on "A" are you?

 

[Przemek]

Aperture chatter describes this quite accurate and looks similar to what is shown in below video

And aperture is not set on "A", please believe me 😉
Maybe I'm paranoid, I'm used to quiet operation with the Ricoh and can't remember anything like that happening with my original x100.
Let's see what Fuji has to say about that.

 

[willie_901]

I have not experienced a this issue.

Do you have all energy saving options disabled?

Are you using the auto LCD/EVF brightness where the camera adjusts the display gain to keep the brightness constant regardless of the real brightness?

Are you using a shutter half press to set the aperture or are you using the AFL/AEL button on the back of the body?

 

[wrenhunter]

You say you received it used -- have you tried putting all settings back to factory default? I agree with others -- I have not seen this with my T, and it does smack of some odd configuration.

Yep.

It's quite normal operation.........

Google the phrase for more.

Do you have pre-af enabled?

Rats! I forgot about pre-af!

This could be important.
