Wednesday or Friday, I'll be going to Cad West, so watch this space.
Ah, let us know how you get on. A key reason for my purchase was to try some aviation shots this year and see how I get on. I like the idea of Duxford's fields, I think I'll try that out.
Your experience with the building sounds very like what I found with my first copy. The second one I've got seems better.
When out yesterday with it I found it tricky to lock on to birds in flight but then a) I'm not used to it, I'm not a 'birder' b) they were seagulls, zipping all over the place c) There were loads of them!
By and large though it performed pretty well with running dogs, running kids, trains going past and things
I'm still experimenting with what it can do, how and what I can use it for and what are it's limits at the boundaries because I'm just not used to a big lens like this.
I got a couple of nice 'slice of life' shots because of the distance between me and the subjects.
Some of the more artistic effect shots like the last one posted above worked out well too. (Been 'explored' today so a shot with the new big Tamron is going to get thousands of hits but I bet they would rather it was a picture of an Elk or something)
I do feel a bit conscious wandering around the place with something that large in my hands though, especially with the hood on but I'm terrified I'm going to whack that large front element on something, some time.
It's not that heavy compared to some other large lenses I've picked up, however I took my dinky 40mm with me in my pocket and when I swapped them over it was a nice feeling of release, the camera now felt lighter than air!
Overall I'm very pleased with it. I could tell the IQ was decent from the first copy, this one is the same but the hit and miss of the AF is improved. It's one of those lenses where the overall rendering of the image just seems 'nice'. One key thing is when I import into LR I haven't then felt the need to put in stacks of PP and when I have done some, I've kinda come round to what the original was like.
