If you watched Part One of our video series, you know that Fujifilm produces a full line of binoculars boasting high optical performance and reliability for a vast range of applications. To help you further determine what kind of binoculars fit your needs, today we’re going to talk about the two main types of binoculars: Roof Prism and Porro Prism.

FINALLY A GOOD EXPLINATION OF THE DIFFERENCE
Glad you thought so!

i got frustrated watching these yahoos on here explain porro and roof and all they could say is that one was slimmer and more compact than the other......but i wanted to know which one gives the best quality picture, so after seeing this i think porro is the way to go in the lower cost models
Such a beautiful presentation comming from someone who is doing optics for a living. Thank you for explaining these two technologies so well. Now i am beginning to see why some binoculars cost $20 and others cost $1000. Thanks
Very good information.
Yes indeed - a really helpful video - thanks very much
So,which one is better ?
Mid range Porro gives you the same image quality as a higher range (more expensive) roof binocular.
On the other hand porro is bulkier and heavier.
Therefore roof binoculars are a better choice for tourists, hikers who prefere lower weight and low light performance is not the priority.
Porro is better for hunters who do need a good low light performance and don't mind a little more weight to carry.
However porro binoculars are really sensitive to drops and hits as their prisms can misalign pretty easily - than you'll end up with double vision.
Poro prism binoculars are much more durable and rugged than the roof prism binoculars. I disagree with you.
They can be. Certainly, it is much easier to build a tough porro than a tough roof prism binocular. However, there are phenomenally durable roof prism binoculars. Good examples would be Fraser's M25s. You can literally run over those with a truck and they'll work fine-gyroscope and all. They do, however, cost $4000.
Fujinon's stabiscope is still a porro. I'm pretty sure you could also run those over with a truck.
I own very tough roofs and very tough porros. These days, it really does just come down to how they're put together.
