Sony RX10 IV Minimum Focus Distance

I have just uploaded to YouTube a short video that illustrates one possibly confusing point about the minimum focus distance of the Sony DSC-RX10 IV camera. Specifically, that minimum distance is longer in the middle of the camera’s zoom range than it is at either the wide-angle or telephoto end of the zoom range. I came across this fact while writing my recent book, Photographer’s Guide to the Sony DSC-RX10 IV, and I thought it was worthwhile to post a video that shows how this fact affects the camera’s focusing behavior.

Here is the link to the video:

Video on Accessories for the Sony RX10 IV Camera

After publishing Photographer’s Guide to the Sony DSC-RX10 IV, I wanted to make a short video showing several of the accessories for the camera that are discussed in that book. You can get a better idea of how they look and how they work with the camera in a video, where you can see the items from different angles, and actually working in some cases. This video is a supplement to my earlier video on accessories for the RX10 III. I did not include any of the accessories from the earlier video in the new one, so, if you want to see a wider range of accessories for the RX10 IV, check out both videos. The video on accessories for the RX10 III camera is available at https://youtu.be/q2kr8CBYDOQ.

Infrared Photography with Sony RX10 IV Camera

I am in the process of finishing my guide book for the Sony DSC-RX10 IV camera, which I hope to have published by mid-December. Today I checked to see how well the camera does at taking infrared photos using a Hoya R72 infrared filter. (The camera uses a 72mm filter, by the way, coincidentally the same number as the filter number.)

Of course, the camera is not designed for infrared photography, so you need to use long shutter speeds to let enough infrared light in through the dark red filter. So, this type of photography is really only suited for stationary subjects such as landscapes. It works best with green trees, grass, and the like, along with blue skies and clouds. But my tests showed that the camera can take this sort of infrared photograph. I am posting an example here, which is also included in my upcoming book. This image was taken in Manual exposure mode with a shutter speed of 4 seconds at f/5.6 and ISO manually set at 1250.
