Current photographic interests are aviation with some landscapes and general photography. Now I've got some more free time I'm looking to get into bird photography as well.
Current gear is an EOS 40D with 70-200 f4 and 400 f5.6. I'm starting to feel a little restricted by the noise levels above 400 iso and also I'm certain the auto focus in later bodies is much better as will be the higher iso performance. At time's I also find the 400mm fixed focal length restricting for aviation shots e.g it can be too tight compositional for formation or larger aircraft but I do like the sharpness it offers.
So here are my thoughts
1) Keep the 40D but swap my existing lenses for a 100-400 mark 2. Hopefully the zoom is as sharp at the long end as the 400 5.6. I know the mark 1 wasn't
2) Keep my existing lenses but splash out for a 7d2.
3) Swap existing lenses for a Sigma 150-600. Currently this has the least appeal as it's a bit of a beast to haul about for genral photography outings.
So your input appreciated to help with the decision
