Good day Tannin, thank you for the insight.
I have a Tamron 18-400, all things considered it does offer fairly good quality shots. However it does have reach limitations that I now understand can’t be overcome with a converter. I am confined to a less expensive lens than the Canon prime lenses.
Not to give up, my thoughts are moving to a better camera or a Sigma 150-600.
As you say biting the bullet for a more expensive lens right off may work out cheaper in the long run. With photography one is never bored, things change quickly.
Kind regards,
Dennis (Journeyman)
