Focus Error!

Are you using a UV filter with an adapter? If so, putting this on backward will restrict the lens from breathing in and out thus it was unable to focus freely, causing this error. message. This happened to me and I had to keep powering off/on the camera until I figured it out. Good Luck!

Marry me! Yes, I do use a UV filter. Plus I have an adapter attached to it to use a hood. Just taken all of them off. And ... we are go again. Screwed UV on in reverse. Still OK. Added adapter & hood. Still OK.

HUGE THANKS (especially as I have $100 repair bill for an XPro2 and I also live in Thailand, where communications with Fuji Thailand in Bangkok are ‘problematic’ and drink-inducing.)

Thanks for kicking off 2019 on a high note.

This is the #1 cause of lens error ever since the original x100 came out. I'm glad everything worked out.

What about the adapter ring I use to attach my JJC lens hood? Does this affect lens movement too? Presumably the official Fuji lens hood also requires an adapter ring. If so Fuji are (knowingly?) contributing to the problem.

i used to have a u/v filter + hood adapter ring’sttached. I had further Focus Error! problems so I’ve removed the filter. Let’s see what happens now.

As mentioned before, it’s a pity Fuji haven’t put out an advisory note on this. I did ask for clarification on several Fuji Twitter sites. Still waiting.

The solution is using a threaded spacing ring that just puts a space between a too thick filter mount or lens hood. I have been successfully doing this with an extra thin B&W filter on a 60mm macro which displayed a focus error when used on infinite (or thereabouts).

 

This is an example of a spacing ring which has the same thread back/front and thin mount in between (you need to find the right thickness)

yes, a spacer,  not an adapter, there are special spacers, this serves the purpose to allow focusing without impeding the movement of the lens (which is causing the error) of course the spacer has to be thin.

I had this problem when I used my 60mm with a different lens hood than the gigantic original one. I used UV filter by B&W which was thin enough not to jam the focusing movement when focusing at infinity or longer distances.

I have an adapter, UV filter, and hood combo on my X100F and have never had the error come up. I've used the trio on my X100S and X100T also with no problems. The key is to use filters that are thin enough not to block the path of the lens movement. FYI, I've always used B+W filters on my X100's.

Hello StephenPG

Thanks for the advice. I was doing that: JJC adapter ring + u/v  filter + JJC hood. Focus issues disappeared after I removed the filter!

I traded in the X100F for a 100V. A YouTuber recommended using a B+W filter to sandwich between the JJC adapter and lens hood, which I’ve done. No focus issues to date. So same system as before, just different filter. I’m not sure if the B+W is thicker or thinner than the previous one (just cheap, off the shelf). The lens on the 100V has been tweaked, so maybe it doesn’t travel out as far as the one on the 100F. Excuse my lack of technical geekery.

If I meet an 100V owner who has ‘weather sealed’ the lens using Fuji’s pricey official adapter, it may be worth doing a thickness comparison.

Sorry: can’t remember what I did with the 100F. With 100V: removed the lens adapter ring (that came with the camera); replaced it with the JJC ring (came with hood); screwed B+W filter into it; attached hood to it.

With the 100F, I may have added a spacer ring before adding the JJC ring. Instead of screwing this in clockwise, it was turned around (ie backwards) and the inner ring screwed in anti-clockwise. Try a Google search for better help.

      How to turn OFF the wifi antenna

      By jerryy · Posted

      It is really easy to find out if the wifi is on. Your computer or tablet or cell phone will have a network settings dealing with wifi, bluetooth, ethernet or “other”. Open that up and go into the section for wifi, and take note of which networks are listed. Turn on the camera and keep watching the list of networks. If your camera’s wifi is turned on, a new network should suddenly show up in your computer/tablet/phone’s network listings. Now go into the camera’s menus and start a wireless connection (the x-app or camera remote app can help you with this). You should see a network show up now. It is not hidden because it has to be visible so that your computer/tablet/phone can join the camera’s network to transfer images. Turn the camera off and that network should disappear. Turn the camera back on and see what happens.

      Sigma 500mm F4 + XH2S?

      By Stogursey · Posted

      I think my Fuji 150-600 F8 is a brilliant wildlife lens in terms of sharpness, portability and value but the small aperture does cause issues at the start and end of the day - even pushing the ISO as far as I dare, I can see shutter speed down to 1/25s - stabilisation isn't an issue but asking a deer to stand still for that is too much! In the same situation, an F4 would give 1/100s so the difference to the success rate would be phenomenal... and that's without the other improvements like shallower depth of field. I also find that the Fuji's subject detect AF gets pretty iffy in low light - I keep updating to the latest firmware but it doesn't seem to get any better. I was originally looking at the Nikon 500mm F4 E but good examples secondhand are still reasonably expensive but like-for-like Sigma lenses are around half the price. Reviews I have read suggest that they are as good optically, AF performance and IS-wise but you gain a few hundred grams of weight (but less than the older Nikon model). For a couple of grand, I can live with that. Does anyone have any experience mounting one on an XH2S? What about with the 1.4 teleconverter? It feels like that is pushing it anyway - hefty lens + TC + Fringer all sounds a bit...wobbly? It is on the Fringer approved list but I am wary about AF speed in particular. I had also considered looking for a used Nikon 400mm F2.8, which would be even faster (and heavier) and could couple with a TC to give 560mm F4 but again, it is that lens+TC+Fringer combination that worries me as being just too many links in the chain. Of course, what I really want is a native Fuji prime but that doesn't seem to be on the horizon - and if you look at what Nikon and Sony are doing, if Fuji do ever bring out a 500mm prime, it will probably be a small, light and cheapish F5.6, which is only 2/3 stop better than my zoom at the same focal length. Any thoughts anyone?

      How to turn OFF the wifi antenna

      By Greybeard · Posted

      The Amazon link is an annoying feature of this forum - its automatic and is applied to every post for advertising purposes. My question was - how do you know the camera wi-fi is on and requires turning off? I would have thought this would just use up the battery for no purpose if you aren't specifically using a function that requires wi-fi.
