OK, I figure I must be doing something wrong. Using FW4, wide tracking mode and AF-C with a 35mm lens. When I half press and hold the shutter release the camera just hunts back and forth and never locks on to the subject - even if it is static and fills the focus points.

 

So what am I doing wrong ?

MD5 and SHA-256 checksums are different between the early "beta" version and the official "fuji" version.   I'm also noticing performance differences in low light AF capability. I was having some pr

^^ not sure if this helps, but I personally use the front custom button to change focus mode...

I'm impressed with FW 4.0 - understatement! Will be doing more testing later today. However, I'm interested in hearing about performance with FW 4.0 compared with your DSLR or some of the other mirrorless systems said to have superior focusing abilities. So, if you have access to say, a Sony A6000 for example, could you tell us about how the X-T1's performance compared both before and after the 4.0 update? 

 

I'm convinced that there is a significant improvement over previous firmware AF performance. No argument with that, since I was often frustrated with AF with previous FW. And, Fuji has provided incremental improvements since 1.0. I was far less frustrated by the time 3.0 came around. 4.0 so far seems more like a 6.0 release in terms of the increase in AF performance when compared to previous updates. That is really cool. But, has Fuji closed the AF performance gap with competing systems. If not, what do you think Fuji needs to do to achieve parity?

 

I have access to both a D3S with mostly primes lenses (35mm F1.8 and 50mm F1.8 among others) and a D800 with 24-70mm F2.8 and while the X-T1 with new upgrade is certainly good, it still can't compete against those 2 old monsters DSLR, specially the D800 with 24-70mm, that body lens combo is just insanly fast, you hardly need to do any half press for the focus to lock on.

 

Now, the closest competitor I have in house is my lil' Nikon1 AW1 with almost all lenses aside the 10-100mm and 70-300mm. 

In good light condition, the AW1 is really close of the D3S in term of focusing speed, we have to leave it to Nikon, they are awesomely good on the AF for their bodies.

 

So how does it match up ? Well, my AW1 with the 18.5mm F1.8 (50mm eq.) against my 35mm F1.4 on X-T1, the AW1 wins up with a good margin in good light condition, the update did good on the body but the lens could really use some update(s ?), but as soon as we start hitting the low light and the ISO shoots up, the X-T1 is catching up really good, around 3200 ISO the AW1 pretty much lost the battle, it can still grab a lock but with a bit more hunting and IQ goes down the drain.

 

In overall, the 35mm F1.4 is a really pretty lens, but it does shows its age, I could be tempted by the 35mm F2 WR that is going to be released end of this year but I love the bokeh and "spirit" of this 35mm too much to just replace it because it's not as fast other 50mm equivalent.

 

While I do not own a Sony A6000, I guess that depending on the lens, the X-T1 could be up to par with it, give or take 10-15% for error margin.

 

 

OK, I figure I must be doing something wrong. Using FW4, wide tracking mode and AF-C with a 35mm lens. When I half press and hold the shutter release the camera just hunts back and forth and never locks on to the subject - even if it is static and fills the focus points.

 

So what am I doing wrong ?

 

 

Don't use the AF-C on static subjects, the AF-C is expecting to have a moving subject, if everything is static, it tries to compensate for something that doesn't move.

Thanks for the response Darknj. I think you misunderstood my point.....Its not locking on to anything moving or static.

 

If I set drive mode to CH, then it behaves more or less as I would expect. But in CL and S drive modes the AF just judders and does not lock. The viewfinder display is different too between CH and the other two.

Humm... Weird behavior, in all honesty I couldn't say what could be causing it since I haven't toyed with with the wide tracking in AF-C yet.

Quick question tho, are you using only MS or a mix of MS + ES ? I recall reading something about the AF-C wide zone tracking not playing nicely with any shutter mode beside MS.

Since I've installed FW 4.0, I've noticed that the eye sensor IR spot remains lit (red glow) when I switch off the camera. It's weird.

This happens only if "performance mode" is activated. In normal mode, it still behaves normally.

Have you noticed the same thing or am I the only one?

Thanks guy for your feebacks.

It is weird indeed, but not new at all, as I've been observing the same behavior since FW3. Consider it a standby light.

Thank you for your feedback. I guess I've never noticed it before (it's been only 2 weeks hat I bought the camera). I was afraid that it could drain the battery even more with this "standby light" on... Why is it only lit when performance mode is enabled? It's a mystery.

Sounds like a harmless bug. But don't worry, it will take at least a few months to drain your battery with such "powerful" infrared LED alone. Other standby circuits combined with battery's own self discharge will finish the job much faster.

Good news for you. Not anymore ! I just tried it out and it was working on AF-S :D

 

Meaning back-button focusing. I wish I could say the same here. I have the buttons switched: AE-L for back focus and AF-L to lock exposure. I was always used to having the AF-L button in that position. With the camera set to MF: no problem. It all works. But with AF-S or AF-C, neither back button has any effect. I tried swapping their positions to the default -- no change. They function only in manual-focus mode.

 

Bit of a disappointment but perhaps it depends on which lens you're using. Seems like a bug to me.

A moment later ... it is lens-dependent. I replaced the 35 with the 23 -- a clutch lens. I locked the focus ring -- now it's in autofocus mode. With the camera's own focus switch set to either AF-S or AF-C: still no back-button functionality. But when I moved the focus switch on the camera to M, both of the back-buttons started working.

 

I'm going to report it as a bug. Limiting the functionality that severely doesn't seem like much of a feature.

Already posted this as another topic.  Didn't read this topic title correctly, but I get this 'wonderful' message after trying to focus a few times.

The new AF microsite shows the AF+MF settings under the new AF menu on P1 of settings (along with most other AF settings like face detection), however, on my camera, AF+MF is sitting on P5 of the settings, just above AF+AE interlock. Is this the case with everyone else?

 

Also, I've noticed under the new firmware with the 18-135mm, it seems like the IS motors in the lens are running full time, whenever the camera is turned on, regardless of the IS setting 1 or 2. I don't remember this being the case under old firmware. Anyone else finding IS is on full time with any lenses on new firmware? It's absolutely killing the battery life..

Ok, even stranger yet. Egad, am I imagining this?

 

Clutch lens -- in this case the 23, in manual focus mode (focus ring turning):

 

Camera focus setting "M": Shutter release has no effect on focus -- completely expected.

Turning focusing ring focuses lens, activating focus-assist feature as it does so. Also expected.

Camera focus setting "C": Shutter release has no effect on focus -- expected.

Turning focusing ring focuses lens and activates focus-assist feature. Expected.

Camera focus setting "S":  Shutter release activates focus.

Turning focusing ring does not activate focus-assist feature.

And the weirdest thing of all: turning the focusing ring DOES NOT focus the lens.
 

Like the nice lady on TV used to say: what what WHAT?

      pocket wizard and XT5?

      By LBAbrams · Posted

      Has anyone successfully used pocket wizards with an XT5? I cannot get it to fire.  Do Fujis and pocket wizards get along? Thanks in advance for your wisdom on this, kind readers!

      Grzegorz, Go to the Networking Setting in your camera menu (the last one at the bottom - unless you have a My Menu then that is the last one). There, go to Network Setting and choose the SSID (name) of your WiFi network, type in the password, choose "SET". If you have a functioning DHCP server on your network, the camera should get its IP address (and Subnet_Mask and Gateway). If not, you can enter these manually. It is a little tricky, there will be some zeros already here, move the cursor after the zero and use DEL to delete it and make space in the input fields for your own correct values. If you do not know what to enter, have a look at values in the network settings of your computer and use the same except for the IP address, try some fairly higher number, hopefully you hit an unused one. Usually the values would be something like IP: 192.168.1.188, Subnet Mask: 255.255.255.0, Gateway IP: 192.168.1.1  or something like that, take clues from your computer. The camera and computer must be on the same network. Then in Connection Mode on the camera, choose Wireless Tethering Fixed. And half-press the shutter to exit the menu and get in shooting mode. The red LED should be blinking. If you can look at your network devices, e.g. on your router, you should see the camera there. You can see check the camera settings in the camera menu in the INFORMATION item of the Network Setting menu to see the MAC address of your camera and look for it in the list of devices on your network.  Then use the tethering in your software, e.g. in Capture One. The camera may not show immediately, take a shot and then it should show in the list of available cameras. Good luck. Report back how did you fare.  PS If you have a Windows machine, you need to have Bonjour installed and running. Macs have it.

      X-T30 II Eye Sensor + LCD Image Display viewmode not working

      By grizzski · Posted

      Hey all, I just got my first camera. The X-T30 II. It seems the Eye Sensor + LCD Image Display view-mode is doing the exact same thing as just the Eye Sensor view-mode setting. Any ideas why this is or what's supposed to be happening? Firmware Version: 2.04

      Problem with multi exposure on XT5

      By George_P · Posted

      What GordW said. You have to put the drive mode dial to "S" - Single Frame. If you have it on CL, CH, BKT or Panorama (or HDR), the Multiple Exposure option will be greyed out in the shootng menu. On my X-T5 it works in RAW + JPG and also in JPG only. When Multiple Exposure is switched on, the image quality cannot be set to RAW only. If it was set to RAW only before switching Multiple Exposure On, image quality defaults to RAW+Fine. The result is JPG. After each shot press MENU/OK and after the last one press DISP/BACK.
