Well I did my first real test at an event with the new Sony Z7. Long story short, the results are as I expected. The event was called Just Desserts and was a fund raiser. I agreed to come in and shoot some video for nothing, as my wife is on the board of directors and it was for a very good cause.
I must say that I cheated a bit and left the camera on auto most of the time, so some will say that this review is not the most relative. I really wanted to check out the auto focus issues, especially in low light. Most of the time the auto focus was fairly fast. I did experience the focus hunting we have been hearing about, mostly when I was slow scanning across a crowded room. The lens did not know what to focus on and I still feel a big part of this issue is due to the low light. But I did see shots very similar to Dave williams example. I think my 170s were guilty of this same issue, but maybe not quite as bad. Once it focused, it stayed there. My thoughts before I did this shoot was that I hoped that this would be at least as good as the PD170 for auto focus, and it was. As for low light, it was on the noisy side, but then the lights were very low and I thought quality was as good as the 170. I realize that I should have taken some time to go full manual, and I am kicking myself now for not doing that, as I had plenty of time for that. Also in the auto mode, the picture was on the saturated side. i did not realize until I got home that I could have put it in manual mode and left everything I did not want to control manually in auto. This is what I should have done, but did not. So I apologize that this test is not as thorough as it should have been. All in all I am satisfied with the very low light footage I took and will post a link to that once I get something edited.
