No need for Autofocus when shooting landscape from the plane. I just use a fix setting, a short exposure time and f 11 whenever possible
The problem I find is that most/all modern lenses don’t have the infinity setting at the mechanical stop. It is usually about 1mm away. True; F11 will make that non-critical but F11 or so robs you of a lot of light. Normally I use F8. But whatever I do, I find the focus moves around as the camera is handled. I guess one could, for aerial shots, tape up the focus ring with insulating tape so it can’t move
Lenthamen,
if the Cirrus had a storm window I wouldn’t complain :-))
Actually for photography i use my old Warrior, which has a storm window AND a special photo window.
In 2009 I did a Coffeetable Photo book about Munich, I did all the pictures through the storm window of my Piper …. flying steep turns while looking through the camera …

They are curved.
In that case it should be possible to fit a single-layer optical grade glass in a PA46 cockpit side window – unless it is curved.
PA46 aren’t double glazed either just plastic except for the pilot’s which is heated glass. On the passenger ones there is a light layer of plastic on the inside but as with the citation it is not structural.
Older PA46s have storm windows but they are a major point of structural failure in a pressurised aircraft and will clearly only work when unpressurised. If you have ever seen a cabin pressurised on the ground you will see how much flex there is in the plastic and glass and why photos won’t work well.
Old TB20s have the little opening window, but not in a very useful position.
Incidentally I have found that typical DSLR phase-based focus (which is used in the viewfinder mode) works sub-optimally through any window. The contrast-based focus (which is used in the Live View mode) works through anything (if it works at all).
Thet’s the one thing i don’t ike about the Cirrus, and I don’t even bother to carry the professional camera … makes no sense.
Don’t the Cirrus have storm windows? I always open the side window to take a proper picture.
The windshields and opening side windows in Citations are not double glazed.
No, but around one inch thick curved plastic. I am usually not able to get decent photos through these windows. Often enough, the autofocus of the camera is not even able to lock onto something.
The windshields and opening side windows in Citations are not double glazed. They are plastic. The passenger windows are double glazed for comfort reasons, but only the outer part is the pressure vessel.
The windshields in King Airs are two plies of glass.
But turboprop windows add a whole level of difficulty.
So, Peter, can we infer from that, that the – long overdue! – Jetprop is finally cleared for the approach ?
Btw, these fine folks may be able to point you in the right direction
