By an adaptor do you mean an extension tube or a close-up lens for the filter thread? I would say do not use a zoom. The 33mm with an extension tube might be your best bet.

If you have a lens attached it's more likely the lens. The lenses with electromagnetic focusing have a freely moving focus assembly until the camera is turned on. That is normal. If it's in the body there is a problem.

I can say that v4 firmware works fine in my x-t5.

Have you seen it on other pictures since?

You have to shoot in raw and jpeg to see the crops but still get the raw.

Good grief! Is this a joke? I really cannot imagine what is wrong. I have had an X-T5 for over a year. I don't have any focus issues and I have made many exhibition prints up to A2 size. I can say this. No, it will not recognise different objects automatically. You have to set the required object. However, you shouldn't really need that function for general shooting anyway. Assign a button to face detect and set the eye detect to auto. I rarely have an out of focus portrait. Bear in mind that if you are using your zoom at the long end, the depth of field wil, be narrow. What do you want pixel shift for? Unless you want to make billboard size enlargements you don't need it. Also, it only works with the camera locked down on a tripod and a subject that is absolutely still. What body wear problems? I have not experienced any. The X-T5 is not a video centric camera. I have not heard of any overheating problems though.

The x-t5 is certainly an upgrade on the x-t3, not least of which is the bigger battery, but it really is difficult to advise you. The x-s20 is ergonomically a very different camera to the x-t5. It is so important to feel comfortable with a camera. Is there a camera dealer that you could visit to try them out? Another thing is that the x-s20 is 26mp and the x- t5 is 40mp. If you don't want to make big prints it is no advantage in having 40mp.

I have the 23mm f2 and mine doesn't rattle. So unfortunately it does look like something is wrong.

Frankly the difference looks too small to be significant. All lenses are sharper in the image centre.

Of course, some of this is down to marketing. However, Fuji are restricted by what sensors are available to them. Fuji make or specify the filters that are positioned over the sensels but they do not make the silicon. There are very few manufacturers that do, because setting up the fabs is hugely expensive. Fuji use Sony, who are probably making the best available the moment, but that means that Fuji are bound by what Sony make. In any case the difference between 36mp and 40mp is too small to be significant. Finally, the question of resolution. Resolution is an area defined factor. To double the sensor resolution you have to have four times the number of pixels. So you can see that going from 26 to 40 makes sense. I guess that Fuji decided that their target buyers wanted more resolution. They had to do something to make the x-t5 different to the 4. Maybe Fuji could have offered a 26mp version of the x-t5, but because of differences in the electronics that would be expensive for them to do.

Wouldn't that heat shrink tubing mean that you would no longer be able to move the ring? How would you add the necessary o ring to seal the mount? How would you test it without risking it?

In the first photo the camera has focused on the nearest leaf. In the second it has focused somewhere on the background. This sort of random behaviour is definitely not a normal characteristic of the x-t5. When you take the first half pressure on the shutter button, assuming you are set for single focus, you should see a green square in the viewfinder which indicates where the focus will be. Set the focus area to single point and try another test. Personally I never use the touch screen for the reasons that others have written here.

Sorry about my dumb misunderstanding. .

Sorry, I didn't finish that comment. I don't, know what is going on but yes, try a different card. Also, always format the card in the camera. I expect you did, but I thought I would mention. There is no point in not using lossless compression by the way.

Use lossles compression.
