Most people around me who like shooting pictures are using DSLR cameras. They also seems like the mainstream of the Japanese photography world. I have never used any of those kind of cameras for many reasons.
Before I start complaining about DSLRs, I want to clarify that I know they are still efficient tools for photography, especially for capturing sports. Canon and Nikon built an almost perfect lens system. DSLRs are stable and reliable, which can definitely help professionals to get the job done.
However, for me they are no more than ugly heavy blocks. The design of most DSLRs were a disaster. They completely looked like tools without any philosophy. In addition, they are also heavy, requiring people to carry a big bag to carry their DSLR around if they want to have two or more lenses at the same time.
Besides, I can say that DSLR is becoming obsolete after Sony’s new lineup of full frame mirrorless cameras. If a far compact camera has the same sensor size as a DSLR, why do people need DSLRs anymore? Not to mention the DSLRs many people own are just APS-C sensor cameras. At the APS-C level, there are even more choices besides Sony. For example, Fujifilm is producing nice solid APS-C cameras.
The point is only if you have a big sensor and proper lens, you will get the image quality you want theoretically. However, the mobility of a camera means more to me. I’m carrying a tiny Sigma compact camera with me when I go out. It has a unique Foveon APS-C size sensor and a 28mm lens. The image quality is really decent, at least better than the iPhone. If I want a changeable lens camera, mirroless and rangefinder would be my option. Again, for their compact size. By adding the mount adapter, I can even use SLR lenses on those cameras.
