Originally posted by C_Jones If you go the K-3 III route, it will give you performance improvement with the Sigma 150-500.

Also, it will give you high performance with other lenses for Pentax.
Hey, K3 III plus 150-450mm equals] around 2000$ plus 2000$ that is over 4000$ plus all arounds.
OP seems to have another budget.
I did put mony aside for the K3 III - however that was more than for a K1.
I wanted as OP a entusiast birdie lens as well.
I bougt a Tamron 150-600mm gen. 2 and a Nikon D500 for less. than the K3 III. My first non-pentax since 1974.
No K3 III, however I have the K1 and K3 with a load of lenses. They are as well as when they arived.
For the fun of it I also have a Lumix lx10/15 in the pocket and a Nikon Coollpix P950.
Printer is Epson SC P800.
