Optics Viper HD Roof Prism Binoculars 10x42, Green, V201

Met all my expectations, great for Wild Life photography and Bird Spotting.

Ottimo prodotto, un po’ di aberrazione cromatica in condizioni di alto contrasto ma tutto sommato non invasiva. Aggiornamento: ho perso il copri oculare in una uscita naturalistica, contattato il centro assistenza mi hanno spedito senza alcuna spesa un kit completo di pezzi di ricambio dal loro centro UK dopo 1 giorno dalla mia richiesta di comprarli.

So, so good! Clear vision with crystal clarity that is like seeing in 3D. These work superbly from fairly close to distant objects, I absolutely love these bins. They come with a fancy chest harness bag that is very funky and aren’t so heavy that you couldn’t cart them around all day.

Tras darle muchas vueltas me quedé con estos 10x42. La nitidez es excelente y, para mi gusto, apenas se aprecia aberración cromática. No son los más luminosos que he probado, pero me parece que es el sacrificio por la nitidez y la poca AC. Escogí X10 porque frecuento zonas de aves acuáticas y de grandes mamíferos. Si buscas unos prismáticos para bosque o distancias intermedias me quedaría en el 8x42 que me parece que balancea un poco mejor el ángulo de visión y la luminosidad.

The binoculars I purchased are of really good quality, unfortunately once I received them I realised I should have chosen a lower magnification, my fault ! Amazon have been very understanding and set up a return for me and I will receive a full refund when this is done. In the meantime I have already remade my purchase with amazon for a lower magnification pair and looking forward to receiving those.

I bought these to replace a $200 Nikon set. The Nikons were fine but these are extremely good. I used them (10x40) on an African safari and compared them to colleagues' 6x30 and 10x40 Swarowski's. These were better at low light gathering than the smaller Swars, and about equal to the bigger ones. I noticed no colour distortion of edge effects (minimal). Easy to set up and use tracking moving animals. Only complaint is the rather cheap way of attaching the objective lens covers (held in place with a rubber ring). I lost one the first time out, though a friend found it for me. By contrast the Swar's have an attachment built into the objective lens - very nice. However, for the price I believe these are an excellent acquisition.
