Roof Prism Vs Bak 4

So if you re on a tight budget go ahead and look for a porro set sporting bak 4 prisms.

Roof prism vs bak 4.

Porros are far easier to build and have an advantage over roofs in optical clarity. They are fully multi coated phase coated bak 4 prisms. However just like roof prisms not all porro prisms are created equal and prisms made form bak 4 glass are usually better than those made from bk7 glass. They are easy to grip with their durable rubber armored coating.

They ll provide just as vibrant an image as a corresponding roof set at a fraction of the cost. However now my wife wants her own binoculars. Roofs use expensive coatings design to match the best porros optical advantage. This doesn t mean binoculars made of bk 7 prisms are not usable or produce a bad image.

Roof prism bino sets are often much more expensive than porro designs of the same magnification. Because the objective lenses are often spaced wider than roof prisms they can also sometimes produce a slightly better stereoscopic image. Bak 4 quality is a lot better. For 140 i think they are great.

But in the optics world that preference will certainly help you in the buying process. You gave them an image quality of 7. If you re a guy or gal who has a type you might be perceived as being shallow. It s just significantly different from bak 4 quality.

And they re much better for overall general use. Bk 7 prisms are also used usually in lower priced binoculars. In the comparisons below i am making the assumption that the quality of glass used to make the prism are of equal quality. Prisms are made of a glass and depending on the type of glass the image produced by binocular can be either sharp clear and bright or vice versa.

Bk7 vs bak4 and porro prism vs roof prism. These are satisfactory but inferior to the bak 4 prisms. Plus they come with turn and slide. Binoculars with bk 7 prisms can be judged by a squared off side to the general roundness of the image.

Refraction and partial reflection. One highlight is they include bak 4 porro prisms which gives them a unique design and shape.
