Great picture. Do you remember how close you were to the subject? I had a look through one on my camera this week, and I liked the feel of it. i went outside the shop and had a play. It focuses quite closely which would be good for my garden etc, but I'm not sure about the maximum distance at which I could get a decent image ; there weren't any suitable distance shots ie birds to enable me to make a meaningful judgement. I think it's a superb lens - I haven't boned up on the bokeh stuff yet so I wouldn't have known what I was looking at.Am I going to get a significant increase  in image size/quality if I go for the Tamron 150-600?
Don’t get too hung up on the bokeh comment….many people didn’t seem as anal I was about it. lol
Don’t get me wrong, I kept the lens for ages and it was only me deciding to try out Sony equipment that caused me to px the d850 and 500pf. If I am being honest ….if I had a magic wand I would try to go back to that combination.:needsahug:


Regarding distance I would say 50feet away.  without going back to the original NEF I don’t know if it’s been cropped ….so it makes size comparison difficult. 

The other thing about the 500pf is the 1.4x teleconverter worked flawlessly with it only losing 1/2stop of light and gave c.750mm. I always believed that using teleconverter should be reserved for fixed prime lenses (like the 500pf) and not zooms, but the Sony 200-600 has been a revelation when coupled with its 1.4x converter. So maybe the Tamron would be ok?  

I believe Jeff (black fox) uses that lens but on a DX body(?)….so his 600mm is probably 840mm equivalent. Send him a PM and get his opinion….he is a very experience wildlife photographer. I cannot believe he would be using an inferior lens!!! For me the decision would be more about cost, weight, features* and need for zoom.

*eg The 500pf has a lock-on feature that enables you to “store” a focus point, while enabling you to then carry on shooting other subjects until you want to return to the stored position/focus point.
