It seems to me though that as zoom ranges expand, it becomes technically more difficult to make lenses that don't produce serious distortions, especially at the periphery. Also, the costs go up; the price of the 28-300mm lens is about double that of the 70-300mm lens. So I think your advice is sound.
But with any such lenses, I suspect that really good (read sharp) results depend upon stopping down the lens as much as practicable. In the brilliant light of Antarctica, I don't think that will be an issue. But when I saw your input into a different thread concerning the 70-300mm lens itself, I looked into some of your postings involving that lens. What I learned was that one of your very sharp images was captured at f/13.
What was the f stop that produced the excellent image you've shown here? :confused:
Regardless of what it was, many thanks for your comments here, and best wishes!
