Porro prism binoculars are bigger and heavier in size than roof prism but it is very much popular in traditional days still in the modern era it is equally necessary.
Which is better roof prism or porro prism.
Porro binoculars are usually waterproof and fogproof if you choose a pair from well known manufacturers listed above.
Roof prism bino sets are often much more expensive than porro designs of the same magnification.
Ideally suited to use during a picnic or gathering they are known for their good ergonomics and holding stability.
But inside they had a more complex light path and required much greater optical precision in manufacturing.
So if you re on a tight budget go ahead and look for a porro set sporting bak 4 prisms.
These binoculars are less durable because of these factors such as bulkier and wider in size as well as very difficult to find waterproof quality in these binoculars.
However as manufacturing costs have reduced and techniques for coating the prisms got better you now can often get what i would call a low cost roof prism binocular that comes with silver mirror coatings and phase correction coatings that to my eyes perform as well as any low cost porro prism.
There is a legitimate price difference between the two as well.

So it is for this reason that in theory a cheap porro prism should perform better than an equally costing roof prism.
Porro prism binocular is heavier than roof prism binocular.
As a result they cost more to make.
The porro prism design was simpler and more light efficient and its images showed better contrast.
Good roof prism binoculars demand a more complicated binoculars design and are usually used in more expensive binoculars.
They ll provide just as vibrant an image as a corresponding roof set at a fraction of the cost.
If porro prisms had the same amount of labor and engineering efforts as roof prism binos porro prisms would always be superior.
This makes the binoculars lighter and easier to carry.
