I'm taking D700 14-24 28-70 maybe 135 f/2 Should I pick up a cheapo 70-300 (non VR) for like $150 for some longer landscape pictures? I figure I'll be stopped down to f/8 or so on most of them and it may come in handy. It's a pretty lightweight lens, I think I may grab it and then sell it when I get back... Thoughts on this lens or lenses of this type? Quality should be decent at f/8-f/11 right?
