In the photos - CAC Wirraway (Australian development of the same design that led to the Harvard/Texan). Spitfire. P51 Mustang, Gloster Meteor and CAC Sabre (Australian development of the F86 built with a Rolls Royce Avon engine).
All airborne shots taken with a 5dIII and the new Tamron 150-600.
I say many of these planes at Tyabb last Sunday; but I didn't have as much success as you had.
I struggled to hand hold the Tamron at 600mm and keep the planes in the viewfinder - need a bit more practice (and some weight training)
I managed to catch this one (I think it's the Sopwith Pup).
I noticed a bit of CA around the elevator edges on your Spitfire image - did you turn on the CA removal option in LR? I find this works quite well on the Tamron.
Thanks. Spot on with the Spitfire - in my haste to get it out I missed the lens adjustment after resetting the image d'oh! Lovely shot of the Sopwith! Stick with the practice and weight training - you will get plenty of great images from the lens.
