IMHO still the best Bridge Super Zoom camera around after 7 years. Although there are rumors that the unit is going to be discontinued, I am hopeful that this will not be the case - it has an almost unique place with its fabulous Zeiss optic, long focal range, Stacked/BSI 20MP sensor, in a compact package that still offers all the controls of a MILC but without the bulk. However, the controls have always been a challenge for me because:
1. The menu system is very complex and disjointed, especially compared to that of my Canon, Nikon, and Olympus cameras. The manual was not a huge help, so I got a third-party book: Photographer's Guide to the Sony DSC-RX10 IV by Alexander S White. That was a fountain of information.
2. I was frustrated by the lack of a the lack of buttons on the back for both AEL and BBF, which are my long-established methods of getting both. While I realize there is a focus hold button on the base of the lens I just don't like it and in the heat of shooting wildlife want something that will be more compatible with my muscle memory from my other cameras.

I was actually on the Canon support forum when a couple from the US asked about gear for going on Safari for the first time. When asked what their priorities were, they said that a very small and light camera was much preferred and definitely did not want the Canon FF and ASP-C bodies with big, heavy tele zooms. That brought me to recommend the RX-10. Canon did actually make, and for a while I owned, a camera with a similar zoom range, the PowerShot RXIII, but it honestly a bit of f dog, especially since it came with no built-in viewfinder (IMHO absolutely critical in a lens with an equivalent FL of 600mm, and the add-on EVF unit was bulky, easily knocked, expensive, and used up the hot shoe. It was also slow to focus. Anyway, by this time it was no long being sold.

So began a journey to conquer the menus and controls to bend them to my will and needs as these folks decided to get 2 of them. I taught them the principles of metering, exposure control, and composition over about 8 hours via Skype. While they were digesting all that, I was going through the menu system in absolute detail with the reference materials in hand. I finally came up with a configuration that allows me to use the AEL button as the BBF button, and re-assigns AEL to the SET button, disabled focus from the trigger button and set the camera up for spot focus and spot metering, with animal eye tracking. All of that required a rejigging of a bunch of menu items, plus I reconfigured the options in the Fn menu. I went out and tried it myself, making a few modifications, and came up with a configuration that works well for the conditions I experienced, and expected them to encounter. In particular, being able to select and focus on a specific animal's face or eye: either in a group, or behind a lot of clutter - such as branches. Similarly, I wanted to be able to select a point of mid-reflectance in an area where there might be a lot of contrast. Certainly, there is no guarantee that the subject will offer an 18% reflectance.

I also set up custom configurations that could be recorded to deal with completely different scenarios, and had one with the default settings as an alternative to a camera reset
I wrote down the changes I made in every page and published them as an assistance for those who expressed similar needs: Customizing the RX-10IV for wildlife Feel free to use it as is, or as the basis of your own set of modifications if you are so inclined.

The following images were part of that test series and the subjects specifically selected for those challenges I mentioned: low or highly contrasting light, and locking the eye focus within a cluttered environment. They are not meant to be considered as works of art per se.

All images shot in RAW, brought into PS (which seems to have done some AI stuff on import), modified exposure and noise settings as required - note: I have very limited skills in PS, so I don't do layers, for example. Finally, significantly downsized for publishing.

This first image is of a native wood pigeon, the Kereru, taken before the sun had reached the area in which it was sitting, so it was actually rather dim, and there was some back-lighting, and a lot of clutter. I deliberately chose this images because it demonstrated that the spot focus lock still managed to get the almost obscured eye of the bird. I spot metered on the mid-toned leaves.

This next image I chose because it provided a different challenge in terms of lighting. Had I used area or evaluative metering the background would have been brighter and the bird's plumage would have been blown out. So, in order:
I metered and locked on the shadow of the bird's cheek, locked spot focused on its eye, recomposed and shot.

Conclusion:
Overall, I am happy with this configuration for my needs and I just got a letter back from my folks who are still on their safari:
"We actually really love the camera and feel that the settings you helped us with are just great. Any issues have been all related to human error and lack of experience. Honestly I think the excitement of seeing the first animals and the urgency we felt to capture the moment made the first pictures more difficult to take, but now that we are seeing all the animals for a second and third time we are calmer and that allows us to think on how we should take the picture and get better results."

Considering they had never actually used a dedicated camera before we engaged and they had only about a month to learn, I am encouraged by their feedback.

A couple more sample images

This Siamang Gibbon, was severely back-lit and appeared in deep shadow. Challenges to overcome included that backlight, plus the fact that it is black and was often obscured by vegetation - and was quite a mover!
Metering on the branch on which it was sitting.
Focus on the eye on our left.

The next candidate is a female tiger inside a netted enclosure and who was mostly obscured but pacing along the back. The gap in the vegetation allowed barely a second to get the shot as she was glimpsed.

I pre-metered on the grass, and shot as she came into view at 10 fps. This one was the best

Finally, a couple of close-up shots:

These were taken in a very poorly lit enclosure - for the animals' comfort and protection, with most light from above, and through some pretty thick glass.

The Auckland Elegant Green Gecko is only about 100mm (4") long from nose to tail and they blend in beautifully with their natural habitat. It takes a while to learn to find them! This one was a good challenge as it was both tiny, poorly lit and nestled behind a lot of obstacles.
Spot metering on the shadow area under it's white mouth, and focus on the eye.

This American Greek Lizard is not that tiny, but was again shot behind thick glass and in fairly dark conditions. There was actually some clutter but the minimum focusing distance allowed me to make that disappear.

Great set! I am so appreciative of folks who wring the last bit of performance out of seemingly ordinary equipment. Well done!!

I have a few budget lenses that I work at to get the best photos possible. It is an art as well as a science and I so appreciate when others are really good at it!!

I had a popular Canon bridge camera for a while several years ago, one that most of the birders I see around here use. I had some flickr and some real-life friends who got really great images out of the same model, so beyond expectations. They were so impressive.

Me? Nope. Couldn't get a decent image from it no matter what I tried. No idea why. I blamed the dark, hard to see viewfinder. Sold it to a friend who just wanted a birding camera, and she's happy.

PS The last two, the gecko and the iguana, are my favorites. Brilliant!!
 
Sniping through foliage to very contrasty Kereru (native wood pigeon).
Hand-held, available light.

This is where my customization of the camera has come to the fore - I use single-point centre focus, animal eye focus, single point centre exposure in the following order:
1. Find a place in the image with the desired 18% reflectance and press the SET button (customized to Exposure lock)
2. Find the eye and press the AE Lock button (re-assigned to Focus lock)
3. Recompose and shoot.
This configuration makes it very similar to my Canon, Nikon and Fuji cameras with which I use BBF and BBE so, my muscle memory still holds good.
