Hi, I've been having a focus issue for quite a while, I primarily photograph birds using a 7Dmk2 and a Tamron 150-600. Focus seems to miss a lot randomly and I've no idea if it's down to me, the lens or the body.
I think these two pictures demonstrate the issue, taken less than a second apart, http://imgur.com/a/KXLnd I've not done any post process on either apart from cropping, I focused on the bird, fired off a few shots and refocused, fired off a few more. You can see the first image is quite soft, where the second one you can see a lot of the detail in the feathers...that's generally the sort of sharpness I've come to expect at 600 when I'm fairly close to the subject.
I've got the lens micro-adjusted by -10 at the telephoto end. I'm using the center focus point, on one shot, I generally focus and recompose which usually works great for me.
Surely the focus shouldn't be that inconsistent? I've no idea why this keeps happening, it's very frustrating. I hope someone can give me some advice.
