Steiner’s smallest “Ultrasharp” model unfortunately isn’t – ultra sharp! This is an entry level pocket binocular with a modest optical performance and mechanical drawbacks (focusing via moving objective block, i.e. prone to letting dust and water in). Steiner makes some very good binoculars (see various examples in this collection), but this is not one of them; there are various competing pocket models with better performance at a lower price (e.g. the fully waterproof Nikon Sportstar EX 8×25, see separate post https://binocular.ch/nikon-sportstar-ex-8×25/).
