Hey, I know, another "is that lens right for me thread". But there is a specific question some of you might know an answer to. So here it goes: In August I am lucky enough to go on a RV and hiking trip through Alaska. Of course I am going to bring my camera with me for some nice landscape and wildlife pictures. The question is, would the 75 (which I do not have right now) be ok for wildlife shots? Of course, a longer lens would be even preferable but the 75 is the longest native lens (while still having a wide aperture) as one can get right now. I do have the 75-300 but am afraid that quite often it will be to dark for the lens. That's why I am leaning towards the 75. The plan would be to sap pictures and crop in post. As for the significant price of the lens: I would of course use the lens later on for other opportunities but those would probably not justify the investment. So, any thoughts on the 75 for wildlife (e.g., moos, grizzlies, ...) as well as the occasional landscape and portrait shot (mind you, I also have the 60mm).
