Reply To: you're not a real photographer because your camera is too small/ not full frame

IHF, the A7r is also a full frame camera, as is the A7s 🙂

Full frame and bigger cameras will have the upper hand when it comes to image quality and iso performance compared to smaller sensored cameras. It boils down to simple physics. A full frame camera will have 1.3 stops better noise performance roughly compared to a 1.6x crop camera simply because of the bigger surface area to collect light (assuming exactly the same tech and same resolution). The lenses will also not need to be as sharp at the same resolutions to get the same useable resolution. However, digital cameras reached a good enough level a long time ago. Good enough for professional use and good enough that most clients won’t tell the difference. A full frame camera will by virtue of having the bigger sensor have the advantage in all areas apart from weight of lenses.
