Mongolia. A country of wide panoramas, vast steppes and, as the country\u2019s slogan says, eternal blue skies. I\u2019m privileged enough to guide a tour for WINGS<\/a> in this amazing country; and, in June 2025, I was lucky enough to be able to travel with a pair of the new Victory SFL 10x50s<\/a> \u2013 perfect for birding in wide, open, Mongolia landscape.<\/p>\n\n\n\n

My own binoculars of choice are the SFL 10x40s \u2013 small enough to slip into a tight corner of my often full-to-the-brim backpack, yet with good enough performance and light-gather capabilities to allow for unrestricted birding from dawn till dusk. Not surprisingly, given my sensitivity to size and weight when travelling, I\u2019ve tended to avoid binoculars with a 50 mm objective lens, which are generally on the larger side.<\/p>\n\n\n\n

Step forward the SLF 50s. Bigger than the SFL 40s? Sure. But certainly no bigger than the SF 42s.<\/strong> They sat comfortably in my hand \u2013 the perfect size and shape for gripping on to. Enough heft that they felt solid and steady, even in the strong winds that occasionally whipped up in Mongolia\u2019s open landscape; but light enough that they didn\u2019t drag when worn almost continuously from dawn till dusk over the three weeks of the tour.<\/p>\n\n\n\n

The extra 10 mm on the objective lens compared to the SFL 40s brought clear (and crisp and bright) advantaged \u2013 the clarity of the image thought the SFL 50s was stunning. Never had a Mongolian Lark looked so good.<\/strong><\/p>\n\n\n\n

That wasn\u2019t the only species in my sights with the new SFL 50s \u2013 the trip list was varied and, for a Palearctic birder, mouth-watering: Black-billed Capercaillie, Saxaul Sparrow, a host of migrant warblers, Pacific Swift and Grey-necked Bunting \u2013 to name just a few.<\/p>\n\n\n\n

All in all, while the SLF 50s add a little extra weight and bulk over their compact 40-mm cousins, the gains were worth it.<\/strong> In the sort of open-terrain birding that\u2019s commonplace in Mongolia, 10x magnification is a must; and the 50 mm objective lens meant no compromises were necessary between the magnification and the brightness of the image. Perhaps I ought to say my own binoculars of choice were<\/em> the SFL 10x40s \u2013 I can very easily see myself switching to the SFL 10x50s.<\/strong><\/p>\n\n\n\n
