There is the issue of power, some hubs have a "brick" power supply and others are powered by the host port which will quickly drain a camera battery since the camera usb host port would be required to give each port on the hub enough power to meet the USB specs -- the camera battery does not stand a chance.

Also there is the bandwidth issue, each port on the hub is given data speeds that are a portion of the total the camera port can deliver. According to the USB specs, depending on the device you are trying to attach to the hub port, that portion may be even further restricted so that the main port is not overwhelmed trying to handle the possible data transfer requests. In a manner of speaking, you could starve a program you are trying to feed stills and / or video data to from the camera, if you pass the data through a hub instead of directly.

IT's a "suggestion". Have you tried it?  If it doesn't work, it could be a power issue.

 

I haven’t even got the camera yet. I’m trying to understand as much as possible about the idiosyncratic things that aren’t obvious.

I’m hesitant to connect something Fujifilm recommends against. I thought it was electrical as well. Guess I’ll find out...

Thanks for the input Jerry.I’ll make sure of the bandwidth for the connection before disappointment.

BTW, have you used the Bluetooth/WiFi to transfer image files?

i tried it to make sure the thing worked. For me, using a usb / thunderbolt card reader works better and is a lot faster at moving the image data over to the computer.

USB is USB. you don't need Fuji-approved cable. I use cable microUSB from my old mobile phone (which is a rarity now, more modern phones use USB-C connector)

    • Example: I am using a custom recipe, and I then use the film simulation dial to select a simulation. Are values from the custom recipe carried over, such as highlights, shadow, and white balance etc.? After studying the articles in Fuji X Weekly, this appears to be the case If you set a recipe on one of the C slots its settings will be applied to all the film simulations on the dial. The workaround is to use your 'standard' recipe at C1.   Please clarify this for me . I would have thought the film simulation dial would have no input from other camera settings.   Thank you - Very Confuded!
    • Is this on the X-T30 II? Sounds like you have HDR selected in the shooting menu. The other alternative when you see the "storing" message is that the Clarity setting is non-zero but that doesn't cause multiple clicks.
    • My XS10 came with a Capture One license but my PC at the time would barely run it so I stuck with my ancient version of Picasa.  Bought a new PC and my old Capture One has been deprecated and fuji site only talks about a 3 month trial.  Is there a work around or should I be looking for something else?
    • On aperture priority and single shot, camera clicks twice after one shot and then takes several seconds showing "storing" message.  This is a new camera and did not do this at first.  Does not do this on auto.
    • I have the Fuji 80 mm macro and really like it. It's very sharp and I use it for macro but also for general photography. If you find yourself zoomed to 55, this may land in the right spot. Also, this lens is very good with magnification distortion (pincushion or barrel), which is probably important if you're doing product photography and the product has straight lines. It is autofocus. I hear you don't prioritize that, but there's something else you gain when you have autofocus. You can combine multiple photos taken at slightly different focus distances, using stacking software, and autofocus lets the camera automate the process of taking all these, using focus bracketing. It even calculates how much the focus should change between these exposures. This lens, new, is above your stated budget. Maybe you can find it used? In any case, options are always nice to have, and others may like this option too. So, just a thought. One more thing: I've never used the Laowa macro you mention, but I do have their circular fisheye. I love circular fisheyes, and also have two other brands, and comparing them I find the Laowa is considerably better than the other two. That's a vote for Laowa.
