Just got the Z last week and had a chance to go out and take some shots today. I was using an FA 45-85 on a tripod, except for the dog portrait which was done on an A 35mm. Didn't really plan that one; it just sort of happened. He hates getting his picture taken so you have to be fast.
Coming from a Nikon D850, the Z is pretty easy to use, except for getting used to the nuances of medium format. I had a little trouble getting sharp front-to-back focus and where I would normally shoot f/11 I found myself shooting f/13 or even f/16. And even at that I wasn't seeing the sharpness I expected, but it wasn't too bad. I'm sure it's just the learning curve. I also think this camera needs a good sensor cleaning as I had to do a lot of spot removal in Lightroom.
These were taken at Sloan Canyon Natl. Recreation Area, just up the road about 5 minutes from the house. The lighting was terrible -- bright sky, no clouds, and with a rookie pushing the buttons, well.... they didn't come out too bad for the first time out. They are, for the most part, what I thought medium format would look like. The portrait of Cooper (the dog) came out pretty nice, too, for a spur of the moment shot. Two of them are shameless shots of my Camaro, which I've shot a thousand times, and the one side shot came out awesome.
