Hi! Just wanted to share my thoughts/experience regarding "Focus area" settings using A6400/SEL90M28G. I was very excited to test the new "Tracking" mode; however, I have encountered some difficulties regarding the specific mode and close-up/macro photography. In AF-C - When "Focus area" is set to "Tracking" (Expand/Any size of flexible spot), focus locks on subject fine in almost every situation, and keeps tracking it in real time as expected. However, resulting images are confusing. When using this option for taking pictures of any subjects/objects within further distance (1 meter+), images are very sharp and there are no issues at all. Confusion starts with close-ups. I would not call this extreme macro, just images taken close to min. SEL90M28G focusing distance. As mentioned previously, focus locks on the subject/object very well, and keeps tracking it (the square is green) but the outcome is often out of focus/blurry. In comparison, the exact same scene photographed with AF-C/Flexible spot S/M from the same distance results in much better outcome. Well, there are some missed images (naturally) depending on the scene/conditions - but rarely. Therefore, I do not believe there is anything wrong with the camera, lens itself. What confuses me is the fact that "Tracking" in close-ups is locking on subject/object extremely well, and focus is confirmed (green all the time – leading user to believe that everything is fine), but the result is not as expected for macro/more vague if compared to simply AF-C/Flexible spot without tracking. I do understand that the algorithm is new, and I think it is really great feature. Just wanted to share my thoughts/experience. Perhaps, it could be useful for anybody/any thoughts regarding macro photography. P.S. I know all the macro and manual focus should be used thing. There are some situations where I like AF.
