    Swift Ultra-Lite 8x42 roof review

    One of the twist-up eyecups of my Swift Ultra-Lite 8x 42 recently started to not twist up and down smoothly. I was warned that this might happen by other members of this forum. I peeled off the rubber eyecup covering (held in place with a small amount of that rubber cement stuff which isn't...

    Swift Ultra-Lite 8x42 roof review

    I still love my Swift Ultralite 8x42 roofs. They are keepers. I've done quite a bit of birdwatching with them now and have never been disappointed. They have even worked out well for casual stargazing. Roofs aren't usually recommended for astronomy, but they give a great view as far as I am...

    Swift Ultra-Lite 8x42 roof review

    I've owned the Swift Ultra-Lite 8x42 roof prism binocular for a couple of weeks now and I think I have finally found The One. It seems to fill all of my birding-optics needs within my budget. Perfect eye relief, low minimum interpupillary distance, fast smooth focussing, sharp bright optics, and...
