Great set of pictures looks like the Sigma is working very well!

BF Your air pix of birds are spot on I wish I could do that! Just been photographing Godwits in E Anglia with my new Nikon 80-400 lens on ground spot on but keep missing focus when they are in air. The D810 locks on very fast but in air I just keep missing the focusing hot spot.

Any tips would be super help please?

That's a 1dmk3 its a 1.3 crop sensor only 10 MP but turns out a good image ,I also have a 70d but prefer the other one .
The other beauty of that lens is that if at any time in the future I do decide to return to the nikon fold then sigma wiill (for a charge) change the mount ,so you don't lose your favourite lens by switching camera brands

Looked into this a while ago.

Changing a mount on new only Sigma lenses can be expensive as they only do it in Japan and you have to pay shipping and insurance both ways + their fee.

Probably better off to sell it used or find someone with a Nikon verson and trade. ;-)

I think that the Tamron Adaptall system was great but I guess with modern AF this wont work well as AF tolerances are pretty small.
Hence the need for micro-adjustment feature even in factory made lenses.
Remember when autofocus first came out - it was promoted as an aid for vision impared photographers. :banghead:

things have actually moved on quiet a bit since my last post ,forgot about this TBH ,although i was getting decent enough shots with the lens i wasn't entirely happy with the end result pictures that much .

so i actually sat down a few weeks back and went through loads over a couple of days trying to see what was wrong ,then i took the plunge and decided to fine tune it with the sigma USB DOCK well what a difference it was like someone had stuck a ferrari engine in a mini .

there are various settings you can change one governs the way the o.s works /reacts and i have now set mine to DYNAMIC this helps to keep the focus point steady on the eye whilst hand holding and actually works ,the next thing i altered was the lens A/F and i changed this from fast focus to MAIN FOCUS POINT PRIORITY the two changes combined have turned this from a extremely good lens into a superior one
a sample since changing is underneath

don't really know what to suggest graham ,if the bird is fairly slow then single point a/f should be o.k if a fast erratic flyer then multi point .the only REAL answer is practise till perfect then practise again .make sure all your settings are configured for b.i.f as well .
i find going to somewhere where seagulls gather is good practise a few slices of bread will provide a hour or mores target practice ,even better if you have someone throw the bread out for you
