Yes, for landscape use the bag bellows will easily accomodate the 150, even to moderate close focus (15 feet or so). You can even get away with infinity focusing a 210 with the bag bellows. I would not store the camera with the bag bellows on it however. The bag bellows don't fold well inside the camera when closed for transport. Get the bag bellows- for the Shen Hao, it's cheap - $100. It is also very well made, of thick, pliable leather. It will open up possibilities for using other wide lenses as well... I have a 75mm I shoot from time to time on the Shen Hao and it works quite well with the bag bellows, but ironically, I don't need it that much for the 75, since I seldom need any movements with the 75 for landscape purposes, it's so wide, and the standard bellows will compress enough to get infinity focus. If you go any wider than 75, you'll want the bag again so that you can get the lens close enough to the GG without using a recessed board.
