Hi folks new here, and i'm loving taking photos of my garden birds here in the UK for now. But I have a lens question that I need help with

So I have a Nikon D7500
I currently use a Sigma 100-200 F2.8 with a 1.4 Sigma tele and get some nice shots of small birds but any thing further down the garden is a push to get decent quality.

So.. I'm currently looking at the:

Sigma 100-300mm F4 EX HSM which will still allow me to use me 1.4 tele and still get autofocus
or
Sigma 100-400 F5-6.3 DG OS HSM Contemporary - (It would need a different 1.4 tele I know)

Anyone have both that can offer pros n cons?

 
I ended up going with the Nikon 120-300MM F/2.8 FLED myself..
Thanks BuldMogul: I eventually went for a Sigma 120-400mm F4.5-5.6 APO OS DG... and it works a treat for my needs (see pic below). It was very reasonably priced for my budget. The bonus is it will take the same filters as my 7-200mm and I can put either 1.4x or 2.0 tele on it (manual mode) but doubt I will ever need it for that.. I'll just play with them to see what kind of situation and subject my work at that range.

This pic is obs cropped with some sharpening and denoise... not much else.. very well pleased with it..
