A lot, too, depends upon what it is one is shooting, as some images will require more card space than others, depending upon the amount detail, etc., in the scene.
Yes, the Sony Tough memory cards are not inexpensive, but they are definitely worth it.
There have been times when I've shot as many as 400-450 images in one go -- usually when Alfred has been the subject or other birds such as the hooded mergansers or the geese involved in some interesting action. When shooting in Continuous High it doesn't take long to run through and fill up an entire card's memory! One reason I always carry a small ouch with an extra memory card even when walking around the neighborhood -- just in case I do run into a situation where I'm shooting much more than usual. Of course it is a lot more fun shooting than it is viewing and sorting through that many image files later!
I love my little Sony RX100 M7 but I have to admit I haven't given her much exercise lately; I tend to reach for one of the other two cameras (RX10 M4, A7R IV) most of the time. I have been buying the RX100 series cameras through the years as my travel camera, primarily, but of course this past year there hasn't been any traveling! Each time I would trade in the older one on the current version, but there have been times I wish I'd hung on to the one with the faster lens..... I do love that longer zoom, though, and the popup VF -- wouldn't want to give either of those up now!
