For many it's not about having all the F/Ls only the one or ones that work with the way the see.
I do agree with this. But the thing is, not all of us see in any given focal length.
Sometimes I "see" in 173mm. A moment later, I may see in 164mm. A minute or two after that, I may "see" a different way to capture the same scene, and that capture may best be accomplished by using a focal length of 522mm. Then later that day I may see something else that would best be captured at 300mm. Then I reposition myself to get a bit different angle, and the best way to capture the subject from that position might be 455mm. Then I see another way to shoot that subject, and it would most effectively be done at 118mm. This is typically how any day of photography goes for me. Gazillions of different types of images, all best made at different focal lengths.
I have trouble understanding the concept of "seeing" at just one focal length. I do not doubt that there are those who see that way, it's just that I cannot understand how that would not limit the total number of quality, marketable images one is able to create in any given time period.
When I am shooting subjects that allow me to position and reposition myself as much as I want, and really "work" the composition, I will often end up with many images, and those images typically cover a great range of focal lengths.
If one "sees" in dozens (if not hundreds) of different focal lengths, I just don't see how the use of prime lenses will not at some point, lead to some compromises, and put limitations on the way the photographer is able to capture his/her compositions.
, and i don't stay stuck from just one point of view ...
