Ths 20x optical zoom/480mm reach does not interest anyone for birding or wildlife. One can get that reach with an APS sensor with any 300mm lens with crop. Or a 500mm lens and out to 750 with a crop. I'm assuming the attraction is the compact size which is great for travel, hiking, etc.
I'd say the appeal is "some widlife" with 480mm, rather than none with <150mm. 300mm+ can capture birds of prey and medium sized mammals decently enough. This type of camera can presumably do a decent job on insects as well (depending on focal distance). The main issues relate to image quality and detail at those focal lengths.
Superzoom cameras had a clear purpose and appeal 15 years ago. Given what modern smartphones and affordable, lightweight, crop sensor ILC cameras and lenses now offer to an amateur photographer (even one on a budget), I'm surprised any big brand is making a superzoom camera in 2025. If the main user of the V3 is using it to capture snapshots, memories, documenting things to share on social media/with family and friends - why not choose a phone? That's the big question, surely, that Canon obviously must feel it has answered.
I like superzoom lenses as walkaround lenses but I also like being able to swap that lens out for something better and more appropriate as and when it's worth it. Obviously, a fixed lens superzoom has to work well at all/most of its focal range without that luxury of swapping lenses. In 2025, I can't believe Canon would release a camera like this if the super telephoto range was rubbish. I think the V3 can do wildlife at 480mm. It's just limited to people who maybe aren't looking to own or use a bigger, heavier, longer wildlife set up. I'm sure there are many people out there to whom that applies.
Incidentally, I still see a fair number of superzoom cameras being used when out in rural settings - mainly middle-aged (40-60ish year old) women but some men as well. I reckon the V1 will probably sell 100 units for every 1 of the V3 but for those existing superzoom users, I'm sure a modern autofocus system and all the rest of it will be very much appreciated (for wildlife especially).
