These are still just early results but I am happy to say that the tracking and eye autofocus does work with the motorless A-Mount lenses.\u00a0 The limitations of these lenses is the speed of the autofocus.\u00a0 In other words for a slow moving target like a walking human or a relatively slow moving target like a hummingbird moving in a small area around a food source like a feeder or a flower bush the camera will track the target quite well.<\/p>\n

\"\"<\/a><\/p>\n

But when I had Camera Girl throw a ball to Larold across the lawn I couldn’t even come close to keeping him in the viewfinder.\u00a0 That of course is my own fault.\u00a0 I lack the tracking skill to keep the running dog in front of me.\u00a0 He’s just too damn fast for me.<\/p>\n

\"\"<\/a><\/p>\n

But I’ll think up some better scenario to test the tracking algorithm.\u00a0 The other part of the test is to see whether the lens could autofocus fast enough to keep the target in focus.\u00a0 This has yet to be answered.\u00a0 I’ll look at the results today and see what I find.<\/p>\n","protected":false},"excerpt":{"rendered":"
