    Product Description

    The compact and lightweight Binocular combines aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a 51° apparent angle of view. The optical elements are also fully multi-coated to provide a high transmission of light. With a 8.5x magnification and 21mm objectives, you obtain a notable magnification, insignificant image jitter due to unsteady hands, and a compact form factor. You can easily spot your targets with a wide 6° angular field of view and quickly bring them into focus with a center focus wheel. In addition to observing distant scenes, birds and game, the minimum focus of 20" allows you to study in detail close objects like butterflies, animal footprints, marks or landscape features. To reduce image jitter while observing distant objects or for prolonged observations, you can connect the binocular to a tripod via an integrated 1/4"-20 socket. The binocular also features a 2.5mm exit pupil, a 15mm eye relief, an interpupillary and a diopter adjustments. Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement The binocular is very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate eye glasses wearers, the binocular offers twist-up rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.

    Reviewed in Brazil on May 1, 2023
    Vindo de um tasco essentials 7x35, esse papilio da um baile, muuuito mais capaz, melhores lentes, melhor mecanismo, roda de foco muito mais leve de girar, ajuste de dioptria com clique e marcações, se emprestar e pegar de volta, na precisa ajustar tudo no olho, so decorar a marcação e pronto (eu fiz um risco pequeno pra marcar), bolsa otima com passador pra cinto, mecanismo de clipe da alça muito rapido e facil de tirar e colocar, olhar coisas a 50cm com 8.5x é INCRÍVEL, abre um imenso novo mundo, alem de passaros, vc se encanta com a vida rasteira, formigas, caramujos, abelhas, pedras, cristais, couro cabeludo, letras miudas em bulas, serio, vale o valor, vc ta comprando um binoculo que serve como lupa tbm. Em comparaçao, o tasco 7x35 foca em aprox 5 metros pra frente, contra meio metro desse, em pe vc consegue foco do seu proprio pé...

    De noite é bom, mas com 2.5 de pupila, nao espere uma claridade top, mas muito capaz pela lente ser de qualidade.

    Ponto negativo, pra mim o alivio de 15cm é insuficiente, se eu encostar nao tenho boa imagem, precisei apoiar proximo a sobrancelha pra ter imagem perfeita, talvez o alivio de 17mm seria melhor. E a curva de aprendizagem pra regular o foco perfeito foi um pouco mais dificil do que o tasco pois nesse a pupila é 5mm e no papilio 2,5.

    Resumo: Ótimo produto, lente clara e cores vividas, dioptria com click, mais facil de regular depois de outro usar, foco 50cm incrivel, leve e portatil. Contras, pupila pequena por ser compacto e alivio faltou uns poucos milimetros pra perfeição. VALE O PREÇO.
