I see the importance of Megapixels for Michael's work, but for my type of photography, I do not need more than 24MP. To me 24MP full-frame sensors strike an excellent balance between reflecting light and detail.
When a new camera or lens is announced I am tempted to buy it, thinking it will improve my photos and photography. Yet, the photos that appeal most to me are photos with a strong emotional value rather than technical excellence. I recently purchased the book "Modern Color" about Fred Herzog's pioneering with color photographs. He started with a Zeiss Tesslar, followed by a Leica M3 and later Nikon F. He used Kodachrome film. Photos lack the contrast of modern photographic systems, but I love the gentle colors and - above all - the careful composition and selection of the scenery.
I now try to adopt a “Less Is More” philosophy to resist constantly switching gear, which is difficult because I suffer from GAS ;-)
