Lens for aerial photography
I have only shot them from the ground up. From what I have been told they vibrate a bit so if using a long lens you might get camera shake! I'd go with the 18-250 then you have best of both worlds.
At the beggining there was nothing....

I have been fortunate enough to be offered the chance to go up in a helicopter to take some aerial shots of London and now have the dilemma as to what lens to use. I have the DA 18-250 which I think will be okay or should I use my recently aquired DA* 60-250? Having said that I think that lens may be slightly too big and heavy
If you're shooting through the canopy, you certainly don't want to worry about ultimate sharpness, since it's not achievable. 60mm as a minimum is a restriction I would not want, so I see no advantage in using the 60-250. You probably won't be very high at all if you're over London, so you may well not need the extreme long end either.
Shake reduction is just as useful shooting from an aircraft as it is anywhere else, since the apparent movement is not great, and camera shake is just as present as ever. This is especially true, since holding the camera and pointing it in the direction you want is often quite awkward, given the restrictions of the safety belt.
Personally I'd go for the 18-250. It's likely to be a half-way decent day if you're flying at all, so there'll probably be enough light for such a relatively slow lens.
The most serious problem you'll have to contend with is reflections from the canopy. In practice, a polariser is quite difficult to manage from inside a small aircraft, since even without it, you'll have very little time to frame and shoot as you go past whatever catches your interest. If you're not accustomed to it, faffing with the polariser will simply take too much time, and in any case I don't find it as effective at eliminating reflections from the canopy as I might think it should be. Unless it's an extremely bright day, the two stops you lose, coupled with the slowness of the 18-250, are not worth the additional effort.
One thing you must avoid at all costs is bracing the end of the lens against the canopy, since the high-frequency vibration through the aircraft structure will vibrate the camera beyond the SR's ability to correct.
In my experience, the wider the angle, the more likely you are to catch unwanted reflections, or include unwanted bits of the aircraft, so it may be that you don't need as wide as 18mm.
I don't have an 18-250, but I do have the FA 28-200, and it does quite well...
I took this, this, and this with the K10D and 28-200. You'll probably do better with both hands on the camera.
Edit: and this, which was from a heli, that I wasn't flying.
Edit2: I'd be interested in Dirk's views on this one, since he also has quite a bit of experience taking pictures from an aeroplane.
