Hi. Sorry to hear you have the same issue. But also good to know it’s not just me as many have suggested! There is definitely an issue with Nisi. I just ordered and received the Nisi square hood and filter adaptor which they have updated their website to say is compatible BUT it’s not! I have now been asked by them to submit video of the error to their WhatsApp customer service number and they are looking into it. If you have WhatsApp and want to do the same so they might actually realise there is a problem their customer service team are on +44 7723 860624 (WhatsApp). Here’s a photo showing their filter thread v other companies filter adaptor. Nisi on the left. Clearly not enough room for the lens to move

It shows a focus error and locks up until switched off and on again. Only happens during or immediately after close focusing and in particular when using optical viewfinder if that helps. But crucially it doesn’t report an error if no hood / filter attached. I have tried with Fuji and Hoage filter adaptors plus a uv and it’s fine. Only does it with the Hoage and Nisi all in one models

Used both the Nisi and Hoage all in one type hood/filters with my X100V without any issues. Kept both when I sold my X100v after my X100Vi arrived. Both seemed fine until I needed to do some shots at the minimum focus distance. Both filters produced the Focus Error and so I tried the same shot without a filter and also using Hoage filter adaptor and fujifilm uv filter without any issue. I’m wondering if the extra thread on the camera lens is to give more space for filter adaptors and filters and if the lens extends slightly further when at min focus distance than the V lens did? So this is just a FYI for anyone with these filters on the Vi. Has anyone else experienced any issues? I’m pretty sure it’s not the camera as I can’t replicate the error without a filter or with a filter adaptor and separate filter.

I think I have found a serious bug / problem with the latest firmware on the X-T4. I have found that the camera locks up when trying to take a photo with any of the advanced filters. When I set the left hand dial to advanced and use for example the "Partial Colour Red" option, the camera locks up immediately after taking the shot. I have tested using different lenses, sd cards etc etc - same result. I tested latest firmware update on my X100v using the partial Colour filter setting and that is fine. This feature is one that I don't use often but it seems to affect all the optional filters under advanced on the dial. All other camera modes work flawlessly. I cannot find anything about this yet online so will reach out to Fuji next. I wanted to post this here as thought its something other X-T4 users may like to test and report on so others don't have the same issue as I suspect that unless users make use of this feature, it won't be spotted very quickly. As an added note, once the camera locks up, simply removing and then replacing the battery gets you back in. Only this time until they fix it with a future update, avoid any of the advanced filter modes!!!!
