I am interested in the XF150-600, but an important feature for me is the 4 “Focus Control Buttons.” How accurately does the lens return to the preset focus under various conditions? I am a budding astrophotographer. Focusing on stars is always challenging, and nearly impossible with a slow lens. I understand the Focus Control Button on the XF150-600 remembers its focus even when the camera is off or the lens is removed. Ideally, this would be perfect for astrophotography – focus on infinity during the day, save it, then return to the preset at night. So, I think there are a few related issues to discuss: 1) How accurate is the focus when recalled? 2) What happens if you change the zoom after storing the preset focus? 3) How temperature sensitive is the focus? There would often be a significant temperature drop between saving the preset during the day and nighttime recall, so even if the lens is returned to the exact position, temperature changes might change dimensions that could change the actual focus. Does anyone who has used this function have thoughts on this? Thank you in advance, parkerea

Hello Greybeard, That's exactly it! Two minutes after making that post, I discovered I had to set the dial to “C” to solve the problem Thank you so much for your answer. Happy New Year!
