Now that the dslr tidal wave is over, all I can do is look at what was done in the past. Most people who wanted to record their travel and family used the simplest gear that they could that would give them a half usable picture. Has that really changed?
While there will always be a percentage of folks who want to do something a little better or want to be seen with a flashy camera, what was the percentage in the past? What's your memory of of this? I recall that narrow angle shots were not the norm.
I completely agree about the equipment needs of the most common mode of photography, what I call "casual" photography, mostly to preserve memories of family, friends, travels and such. What I am rejecting is Vincent Laforet's far more extreme claim, the false dichotomy that there will soon be only the two extremes of photographic equipment (a) camera-phones for this "casual photography, and (b) "professional photographic equipment". Because in between these two type of photography, there has for a long time been a substantial number of photographers who want and use things like more telephoto reach or wider angle lens options or macro lenses, but do it with gear of distinctly less that "professional" grade and pricing; gear like 70-300/3.5-5.6 zoom lenses, super-zoom fixed lens digital cameras, and so on. This middle group is far smaller than the "casuals", but still far more numerous than the professionals (plus amateurs who use "professional" equipment) so it puzzles me when I read so many people effectively ignoring their existence in this discussion, or of all the gear that they buy. Just look at all the moderately priced "non-professional grade" telephoto lenses and super-zoom digital cameras, which do things that no phone can come close to.
This is no different than the pattern for a century or so, such as the eras when a preponderance of Brownies or Instamatics or compact 35mm film cameras with 3x or 4x zoom lenses coexisted alongside a smaller but healthy market for a higher levels of non-professional gear.
P. S. Can we also drop the inaccurate and sexist stereotype of entry level DSLR users as being mostly "soccer moms"? I see roughly equal numbers of men and women using DSLRs at tourist locations where a more pocketable camera would probably serve them just as well, and in the college town where I live, I also plenty of young people enjoying photography with inexpensive DSLRs and clearly taking more care in the activity than casual snap-shooters or Instagramographers.
