I had a chance to go to an optics expo at a retail store this year. They had tables set up outside so you could try out different products. Reps from Swarovski, Zeiss, Kowa, Pentax, Nikon, Vortex, Leica, Bushnell,Minox, Meopta. To my eyes the Swarovski had the brightest, clearest image of all the binos I looked through but also had a kind of fishbowl effect when panning with them. The Leica Trinovids also had an excellent image, not quite as bright as the Swaros but the Leica worked better for me when panning with them. What I ended up buying were the Meopta Meostar B1 8x42. For my money they had an image very close to the Leica. If you can, it is best to look with your own eyes through the binoculars you intend to buy.
