If you have $1,000 don't buy a lens you'll sell later like many people have suggested. $1,000 is quite a nice budget to start with so do it right the first time to avoid the hassle of selling lenses later. If you want the 31 get it. I doubt you'll be disappointed.
Originally posted by paperbag846 The quality of the FA limiteds do not make them flexible. The FA 77 might be the best lens I have used, but it's still stuck at 77mm and not exactly a flexible beast. Since it's more expensive than everything else I own, I figure it would be prudent to sell it off and focus on investing my limited funds *wisely* across a *range* of focal lengths.
That is the crux of this issue. Sharpness, colour, contrast, bokeh, all important. The most important thing is focal length.
I politely disagree with your point about length being the most important. The OP mentioned he wanted something less intrusive with nice IQ, so it sounds like "diminutive size and excellent performance " are the most important things to him, not focal length, or he could just buy an 18-135 and 70-300.
If quality is important, any Limited would handle the task, DA or FA. If performance, etc. is required, an FA Limited might be the best option. Also, the thing that makes my FA 77 flexible is my legs. Same thing with my 43. It's a great focal length and my legs help it to be very flexible in many situations.
