Thanks for the ongoing support and info.

If possible I would like opinions on both the Tamron and Sigma 100-400 lenses. My 18-400 Tamron does not reach 400 on the narrow end. I have read reviews on both and both sound ok with no particular clear advantage to either.

I would like to buy an aftermarket 100-400 that has a true 400.

The other possibility is a bridge camera, I understand the downside of these cameras. I also understand there is an upside. Either Sony RX10 IV (or just a V would be good) or Panasonic FZ. Convenience is the goal.

Thank you and kind regards,
Journeyman
