XF 100-400mm on x-t4

Hello,

I just purchased the XF 100-400mm lens for my x-t4. When I reach a focal length of 300+ it asks my camera to turn off and on. Is this a setting issue, or an issue with the lens? I am relatively new at this level photography and type of camera, so please excuse me.

I have this lens and find that at f11 at full extension and a distance of about 20m there is very little depth of field. Frustrating when there is a bird and some branches. 

I called up a depth of field calculator and there is about 60 cm dof. 

I need to be more careful in my focus settings.

    • HI Rufo, I have changed procedures.  I now use the colors space transform (CST) as my first node.  The CST is set up as follows: - Apply the CST effect to the first node. - Color Space is Rec 2020 - Input gamma is FLog - Output color space is Rec 709 - Output gamma is Gamma 2.4 All other nodes to grade the clip proceed the node that contains the color space transform. Hope this helps. Don

    • Interesting, and a bit subtle. I also think it'd be better to activate on a half press. But there seems to be good reasoning behind a number of other choices, so I wonder if there's a good reason behind this one and we're just not seeing it. To some degree IS goes on and off like AF does, but this is an exception, isn't it?
    • I couldn't find my manual so downloaded a PDF copy and did some searching.  From p146 of the manual, regarding Shooting Only stabilisation: "Image stabilization enabled only when the shutter button is pressed halfway (focus mode C) or the shutter is released." So it appears that the camera is 'working as intended' and that in AF-S the stabilisation mechanism kicks in only as you release the shutter. I think I would prefer it to activate on a half press, like it does in AF-C.
    • Sometime a short break can help to phrase things so that they do not sound annoying, Well that is the hope anyway, so here goes. Having that meter would be nice as well as having the histogram. But having them or not is a minor consideration in terms of what you are wanting to do because the app does not work with intervalometers. The only way you can get a time lapse sequence using the app is to manually click the shutter button, wait then click it again and so on. Even if the meter were there, you would need extremely fast reflexes to see and react to a lighting change by changing the settings and then going back to clicking the shutter button. Doing that for hours would be a feat indeed. The equipment you mention does this by analyzing several past images and predicting what settings to apply to the next incoming image. Right now the app has the live view which will tell you if an area is over or under exposed, but as far as what you are wanting to do without being able to connect the app to an intervalometer, well …
