I know there's supposed to be more of a difference when you're using 35mm vs 4x5 when it comes to changes in the look of an image when changing focal lengths, and even if say a 150mm lens is similar to a 50mm lens, and a 210mm is similar to a 70mm lens, somehow it doesn't quite calculate that way or something?

Basically trying to decide if getting a 210mm is the way to go when I already own a 150mm or if I should go straight to a 300mm (or very close to that) which is also something I want for landscapes more than portraits.

For portraits, I rather use a 210mm than a 300mm but that's just me.
