It depends on what your using them for. The Steiners are great little binoculars for the money. The small objectives don' t pick up much light, but they' re clear and waterproof. For bowhunting in the woods, the 8x22s work fine for me, but I still plan to get a pair of the 8x30s. I' ve never used the Pentax, so I can' t comment on them.
