I'm a bit hesitating to post a link to my testshots with the Sigma as I'm a total newbie with lenses > 200 mm. But maybe there a re other newbies as well, so from newbie to newbie: https://sojujo.smugmug.com/Testshots/Sig...600-Sports

 

Most of them are crops, as 600 mm might be enough for experienced birders (where I'm also a newbie). But I do see them in a distance...  :mellow:

 

Jo, have you thought about the 70-300mm CX?

 

I had a good look at your link and I have to say that the 70-300mm CX on a V1 gives better results. I just got a J5 so I can't quite tell yet how much better it is to the V1.

 

The 70-300mm CX is a very serious lens. It is good for head and shoulder portraits as well as distance objects like the moon.

 

One thing that not too many people talk about is how good it is for macros. I put on a 4T attachment and got something like 3:1 magnification. On its own it's about 1:3 at 300mm (810mm field of view).

 

It's sharp at every focal lenght execept maybe wide-open at 300mm when viewed at 100%.
