I appreciate your comment, the Canon lens you mention is £200 cheaper than the sigma lens I used in the shot at new prices, the reason I uploaded it was to show potentially what's achieveable at reasonable investment.
Plus also to demonstrate settings wise, what was used, you could increase the iso to 200 or 400 or even 800, well within your cameras capabilities to use a similar shutter speed and work at f4 or f5.6 with a lesser lens, given the same conditions. As previously mentioned, back button focusing is a technique worth considering.

This was shot a couple of years ago, on a K5iis with a Sigma 70 - 200 @ 180mm 1/6400 sec F2.8 ISO 200 with spot metering and Continuous AF

All that remains is the K5, sensible offers considered before the weekend otherwise will list on a well known auction site.

I'm based in Gloucester, be happy to meet around half way if you wished to try the kit out first.

Glad to see the shot finally appear! I agree that the 'consumer level' equipment can deliver the goods, although only generally when conditions are good and things are not conspiring against you. I do feel that the Tamron 70-300mm will continue to be a challenging lens for you for this type of photography, and if you have the funds I'd seriously look for good advice for alternatives. There are some very good bird / aircraft / action photographers around here who will know what to look for.
There's two parts to the equation with good IQ for this type of shot ..... there's the autofocus performance, as you've been concerned with here. However fast moving objects will also need a good high shutter speed to be captured sharp, and with your lens you will need to keep a close eye on this, and be ready to increase the ISO to obtain the needed speeds, especially if you're shooting around f8 for example. Certainly this will be a consideration in the dimmer conditions as you've been shooting in.
Do you know what the aperture, ISO and shutter speeds were used for these latest shots?
1. f11 ISO 100 1/800th 300mm.
2. f11 ISO 100 1/500th 300mm.
3. f11 ISO 100 781/50000,( that can't be right) 300mm.
4. f6.3 ISO 100 1/1250 300mm and finally,
5. f5.6 ISO 400 1/1250 300mm. I think they are all correct.
Since these were taken I think that I've learned a little about the ISO and shutter settings to adopt. Unfortunately my camera was being naughty and showing me memory card error and F-- on the rear screen.
It has all gone back to the retailer at their suggestion, so I'll have to make do with my Canon 760D for now. As soon as I get either a replacement or a repair, I'll get going again. I also think the problem may be something that I've done or not done but It is going to be sorted out.
PS BIF with the 760D is a lot easier.
