Suggestions for new kit

[Vautrin]

Hi,

So I've got an olympus E-Volt 510, with the two lenses that came with it (14-40mm f 4 & 40-80mm f4), and the pancake lens (25mm f2).

I'd like to buy another lens or two, but I'm really confused by the offerings. Every focal length combination has three versions -- the normal quality, high quality, and super high quality.

How can I tell what lens is best? Is it better to have one super high quality lens or three normal quality? What is the difference? Can anyone show me?

I like shooting landscapes and cityscapes. Field of view isnt' so much of a concern for me because normally I throw a series of shots into autopano. So should maybe I think of a gigapano head and a zoom lens?

Thanks in advance for any help,

Dan

I don't have olympus camera, but the difference between the glass I'm guessing is, the more cash u shell out the shaper your images will be.

But how dramatic is the difference? Will I need a magnifying glass? Or will the double the price glass just cause an image to pop?
