I've been through all the seven pages. Interesting, although, my primary interest in this site, is the very high level of technical knowledge. What do I have to say ? Beside all the thinking that I want simply to keep for myself: First, do not judge or impose what people should do, should buy, should think; if everyone thinks and behave alike, the world would be very boring; I am also not a fan of this type of "socialist paradise" where other people, a community, or a government decides how people should be "happy". Two: equipment; I have always been a tech geek - may be because of my background as an engineer - and "fortunately", I'm often active in a sport / action environment where top of the line equipment is highly desirable, and needed, in case I would have to justify I'm shooting with a D5 and not with a D3200. Three: Aperture: from a light gathering perspective, I need less and less high apertures (the best aperture I have is f/2.5) as high ISO quality has so dramatically improved. The most expensive lens I have is the Nikkor 300mm f/2.8 VR II, which I shoot wide open in most of the cases - why, otherwise invest such an amount of money, to only shoot it at f/8 ? - the real reason is that I have often "polluted" backgrounds which I can easily rub away with high apertures. The latter will also be the reason to have a closer look into some other very high aperture lenses.
