That's the good part albeit to long.

Still I took a number of shots as the aircraft was taxying towards me, and only two were really sharp.
One of the slow speed problems is the Aperture and with the 100-400 smaller then F16 you are not likely to make many sharp frames even with 2 feet anchored in Icelandic lava
|Quoting TimdeGroot (Reply 3):|
at low speeds like that you just shoot a lot of images and hope one comes out sharp.
Tell that to the one who pays the fuel bill and you have flown your last mission.
A2A is like any form of photography based on knowledge and expirience(lots of it), hope is best left inside the church but surely no part in any kind of aviation.
|Quoting INNflight (Reply 7):|
It also largely depends on your photo ship. It's a whole different thing shooting from a Cessna 172 leaning out into the propwash than from a B-25's tailgunner position, where you have no wind to deal with at all.
That makes indeed a huge difference although even a big and stable platform can be very shaky.
I would say not effective at all, in fact it makes the problem only bigger.
Which is logical, in lens IS
is designed to counter human shake which is measured in mm.
Turbulence shake is measured in cm ..............on a good day.
Even on the perfect day you still move the camera by cm at the time just to keep focus lock and the IS
is simply not designed to cope with that.
For sure the ones without a mode switch like the 24-105/4 are a pain the the a.......
Another thing is that I found out(after almost screwing up a complete session) the especially the 24-105 IS
can't take any form of G-loading(which btw includes turbulence).
Baldur in general.
- Use the shortest lens possible, the shorter the lens the easier you can get slow shutter speeds.
From all glass used over the years my personal favorite is still the Sigma 24-70/2.8, sturdy as a tank and pretty good stopped down.
- Try to get some technical data before the session which will enable you to calculate the required exposure.
Ask the crew during the brief to use the finest pitch possible in order to increase prop rpm(if the a/c in question can of course.....DC3, F.27 etc).
Small a/c useally can't but they have a high prop speed anyway which makes the matter easier.
You can also ask the crew of the object a/c to use a bit flap which enables them to increase power a bit.
- I personally like to shoot short burst of 3 rather then machine gunning the object.
If the conditions aren't good enough to make a good shot in 1 out of 3 you are not gonna make it with 1 out of 10 either.
- Go high if possible, at 6000ft things are a lot quieter then at 1000 to 1500ft.
I imagine that the skies above Iceland are like the Dutch turbulent most of the time albeit due to different reasons in which case one has to accept the way things are.
In 8 year A2A I got 2 opportunities to go really slow and those opportunities didn't last for more then 20 seconds
I'll write you an email about the Neptune.
Take care and good luck,
