Originally posted by chickentender I'm not certain why you need to take 2 of them. These are all very simliar coverages for the most part...
But that said, what kind of trip are you taking? Will there be hiking? How long/far? Is weight or weather a concern? And (a useful tidbit) what camera?
Those Series 1s are some of my favorites.
The coverages are similar - I was looking more at performance (sharpness stopped down - preferably edge to edge). Aberrations matter somewhat, if they're the type that are hard to correct later.
Several national parks. Let's pretend weight is not a concern. Of course, if two lenses are almost the same, I'll go with the lower weight. The reason I'm asking for 2 recommendations is if I feel I can't handle the heavier one, I'll take the lighter one.
Weather is not a concern - I will not shoot if it is raining.
Camera = Pentax K-30.
