Jason Binoculars - Focus Free

Focus Free Binoculars

Jason Binoculars were popular in the 1970s and 1980s for their auto focusing ability.  Bushnell bought out the Jason brand in 1992 and now offers the auto-focusing binoculars under their PermaFocus series. They are completely automatic and focus free.

The lenses are fully coated and give clear, bright, sharp images that are automatically focused as you view through the lenses. You just bring them up to your eyes, aim them at whatever you want to see focused in the field of view and voila, instant clarity!

Bushnell 7x35 PermaFocus (Jason) Binoculars Jason Binoculars - Bushnell AutFocus 7x35

The 7x set of these will of course have less magnification than any of the others in this series, but is a favorite among those who want smaller and lighter binoculars to carry around. These have a particularly wide field of view at 578 feet.

Specifications:

  • Exit Pupil - 5mm
  • Eye Relief - 12mm
  • Field of View - 578-foot
  • Fixed focus
  • Weight - 1.5 lbs.

A review:
"This was my husband's favorite Christmas gift. He wears glasses and has one eye with partial sight. These binoculars work perfectly for him at sports events and for watching birds in our back garden. He says that he can focus on an object immediately and clearly and can catch the action or object before it disappears. He can also pass the binoculars to a friend who can see what's going on without refocusing. This is a great product!" - Mary from Oviedo, FL

Bushnell 10x50 Jason PermaFocus Binoculars Jason Binoculars - 10x50 Bushell PermaFocus

These Jason binoculars give you more magnification, but a little less field of view than the 7x35s at 393 feet instead of 578 feet. It is one-half pound more heavier in weight than the 7x's as well.

Specifications:

  • Exit Pupil - 5mm
  • Eye Relief - 14mm
  • Field of View - 393 feet
  • Fixed Focus
  • Weight - 2 lbs.

A review:
"I gave these to my husband, an avid bird lover for Christmas. We have taken them out quite a few times in the short time we have had them. I think that price does equate with value. These exceeded my expectations." - LKK from McHenry, Illinois

Bushnell (Jason) 12x50 PermaFocus Binoculars Jason Binoculars 12x50 Bushnell Auto Focus

The 12x50s have less than half the field of view of the 7x35s at 265 feet. The exit pupil is a little smaller than both the 7x's and 10x's at 4.2mm instead of 5mm. The larger the exit pupil, the more light is able to come through the lens. At 9mm eye relief, it may be a problem for those with eyeglasses. Eye relief is the distance you can hold the binoculars from your eyes and still see a complete focused field of view.

I would say these would be best for viewing in far away subjects such as at concerts, perhaps hunting or viewing migrating raptors from an overlook.  I would not want to use these for finding fast moving warblers in trees or on a pelagic bird trip because it is more difficult to steady binoculars at higher magnification.  But it is ultimately up to you and what your preference is.  Lots of people did have positive reviews of these.

Specifications

  • Exit Pupil - 4.2mm
  • Eye Relief - 9mm
  • Field of View - 265-foot
  • Fixed focus
  • Weight - 2 lbs.

A review:
"I bought this pair of binoculars for our recent trip to Mexico. What a fantastic surprise! These focused so quickly on far away wildlife, boats, turtles come up to the water's surface and birds in flight. It was sharp, crisp and clear." - Belle from Vernon, PA

From the reviews of users, it is obvious that these "Jason Binoculars" by Bushnell are one of the best out there. People like their durable construction, lightweight feel and the fact that they really can focus on objects fast and quite easily. People use them for a multitude of purposes including bird watching, sporting events, concerts, golfing, hunting, star gazing and lots more. So if you do not want to mess around with adjusting knobs and want quick, easy viewing, then these are the binoculars for you.

The Bushnell focus free jason binoculars are available in the following sizes and magnifications: Compact 8x25, Mid-size 7x35, Full-size: 7x50, 10x50 and 12x50. They are also available in both wide angle (porro) and roof prism binoculars. The wide objective lens is a great feature for letting in lots of light and wide field of views. For a review of the differences between prism design go here: Porro vs Roof Prism Binocular Design. In general, roof prism binoculars will be a little lighter in weight, slimmer in design and more durable but will generally cost more than porro prism binoculars.

So focus-free Jason binoculars give you the convenience of auto-focusing in a well-made, relatively low-priced binocular. Just aim and your target appears not only magnified closer, but instantly in focus as well. Focus free binoculars that have fully coated optics and rubber armoring at this price, you really cannot beat it. Go and give them a try!
