What do you think about the 150-600 Sigma? Ive only got the 50 1.4 for my D610 still and I need me some telephoto!
The 150-600 Contemporary is really good. I don't know how it compares to the Tamron, but based on reading lots of reviews (and handling my own 150-600), it seems to perform just as good at 600mm. The selling point for the Sigma 150-600 over the Tamron was the dock (so I can customize focus limiting, and if the focus ever shifts a bit over time I can re-calibrate without calling in warranty). I haven't had to calibrate my 150-600 at all though. You can build two different custom profiles as well to customize the way the optical stabilization works, and you can also modify your focus limitations more (so if you want one for sports and you know you won't be going to infinity, and only up to say a certain number of feet, you can limit that). Or, if you're doing wildlife and you want a custom setting to 25 feet and beyond, you can do that. Both the Tamron and Sigma come with built-in switches to focus 15 feet and beyond (something like that), but the custom profile can let you set limitations to something further or a more specific confined range.
If you've used the 70-300 VR, the performance of the 150-600 Contemporary is just slightly better at 600mm than the 70-300 VR at 300mm.
On full frame I like it a fair bit better. If you think about the way a crop sensor gets more "detail", it simply collects data onto smaller (but more) pixels which focus on the center-most portion of the lens. If the center-most portion of the lens is only capable of producing say... 6 perception megapixels of sharpness, then a full frame sensor is going to get the same amount of sharpness when cropped in on the exact same shot for the exact same end result (since you won't need those 24 megapixels). The full frame will make use of all of the glass across the lens (and the Sigma has better corner-to-corner sharpness than the Tamron), so if you manage to fill your frame without needing to crop at all, you get an even sharper image off of full frame. Furthermore, that ISO performance on full frame (up to 2 stops worth over equivalent crop sensors) provides so much more in the way of being able to get a usable image, or a croppable image.
Just some things to mention about why the 150-600 is pretty sweet on ff.

Congrats!
(told you to go full frame from the start ;) )
Hah. Yes, you did. But it seemed too steep then. It still seems too steep now!!! I really want a Tamron 15-30 f2.8 VC and Tamron 24-70 f2.8 VC though, and if I were to do some pro work (probably won't) but if I did I'd love to have a 70-200 f2.8!!!!
Honestly though just enjoying 50mm wide open most of the time, really fun. Just missing a fast wide for some landscapes from sunset to night.
