I was reading this thread about the oly 17mm, and I came across an intereting comment that way like this: "Many people like the 35, 50, 90 progression of focal length, and should be right home with the 17. I prefer myself the 28,40, 75..." And it got me thinking... Which progression do you prefer, which progression do you use and why? What does each have to offer? Thank you *note* It quickly became clear that I forgot to put in "I use a different progression" and "I use zooms"... anyone know how to edit polls?
