Optics Viper HD Roof Prism Binoculars 10x42

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.

Good glass at half the price of the “big names”

I have had these binnoculars now for around two years and I have to say that I find the optical performance very disappointing. They are certainly not crystal clear as they should be for the price. Within a very short time I found that the focus was not working correctly. I took them back to the agent who told me that it was the sleeve surrounding the focus ring which was slipping and that I should try rebonding it . This I did and the problem was solved by myself. I gues that I should return them to the manufacturer for assessment under the lifetime guarantee. I bought them as I had lost my 8 x 40 Nikons. These I have now found and they are so much better.

I bought these binoculars to replace a pair of Nikon Monarch 7, which I had lost and used them to whilst on a two week birding holiday in the Pyrenees. The image clarity was between 10%-20% less on Viper binoculars (in a range of lighting conditions) in comparison to my old Nikons. Often I had to get within 20m or birds in order be sure of a correct identification.

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.

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.

Heel goed. Tevreden mee. Goede prijs kwaliteit verhouding.

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.

I have been birding for over 15 years, using lots of different glass, I was surprised to find that these binoculars are on par with the big names at nearly half the cost. Would definitely recommend and buy another vortex product in the future.
