I have a Swarovski ATS 80 High Definition and absolutely love it. As Jeepkid said I beleive it's personal preference when it come to a straight or angled eye piece.My opinion is thatthe angled models offer a bit for versatility over the straight. I use mine for hunting here in Texas and out west and can attest that the better glass is well worth the price when scanning the vast areas, dark timber, mountain sidesetc. I havean adaptor for a camera but have not used it yet.

Look atgetting aspotter as an investment, buy the best that you can afford. Nikon makes a spotter/camera unit as does Zeiss and Swarovski.
