I've got an upcoming safari planned, and still have a few months left to experiment and practice with various settings using the Tamron 150-600 (Sony version without VC) lens mounted to the LA-EA4 adapter on my A7ii. The goal, of course, is to get some fantastic wildlife shots while on safari. After hand held shooting a number of photos today with various settings, I think I've concluded I'm getting the best results using the single shot auto-focus mode with center focus. Using the wide focus setting resulted in the camera not consistently focusing on the intended focus area. I'd definitely like to hear from others that have alternative suggestions on how to best take these long range shots on an adapted zoom. I'm posting two test shots. The first was shot at 150mm, with "wide" focus setting. I hand-held the camera (the lens has some heft) and was attempting to focus on the label of the propane tank. With wide focus mode, it seems like the focus locked on the chair instead of the label. In the second shot from the same position, at 600mm, using single shot AF, the focus clearly locked in on its intended target. Even better, given the shot was taken hand-held with the just over 5 lbs. of lens and adapter attached to the front of the camera, it's obvious that the IBIS does an excellent job. Great to know this lens can be used without a tripod if need be.
