>I want to use it for both portraits and landscapes.For head and shoulders portraits, you won't be satisfied with any RF, an SLR is much better for this. The GW690 (not the wideangle version) is barely able to do that, but not practical. Because of minimum focusing distance. And secondly because of parallax if you're shooting at minimum distance.
If it's your *only* purchase, you'll find an SLR more versarsatile, as a system, and also much cheaper to get the classic 50mm, 80mm, 150mm trifecta (slightly different for 6x7).
