Burris Fullfield

Burris is an American based firm catering mainly to the hunter or outdoors person.  Their Fullfield line of binoculars feature a combination of a moderately wide field of view and long eye relief.  The thinly rubber coated binocular bodies are said to be nitrogen filled and water/fogproof.  The models shown below have rubber fold down eyecups, but I believe later versions have screw down plastic eyecups.  Also, the focus wheel is lockable by a sliding action.  The optical performance of all three models share common characteristics.  Some lateral color and field curvature is noticeable.   Also noticeable are some light leakage and spurious reflections.  Although the optics are said to be multicoated, I don't believe every single surface is - the image isn't quite as bright as on the best models and the reflection from the prisms is brighter than on true fully multicoated optics.   Despite the imperfections noted, I still like the Burris Fullfields for their very comfortable viewing and good quality construction.

Mfr: Unknown, no J-B marks

Date: 1990's

AFOV: ~65 degrees

Eye Relief: ~19mm

Prisms: high index

7x35

TFOV: ~9.3 degrees

A previous owner of this 7x35 attached a Baker style rubber eyeshield and cut down the eyecups, making it like a mini version of the B&L Mark 41.  The image through this is comparable to the Jason GlassesOn but with warmer colors.

8x40

TFOV: ~8.2 degrees

The 8x40 is a nice all around binocular if you don't like the bulk of the 10x50.

10x50

TFOV: ~6.5 degrees

The optics in the Burris 10x50 Fullfield appear to be the same as in the Orion Ultraview 10x50, but with different coatings.  The Orion is advertised as truly fully multicoated, and it does appear slightly brighter.  The Orion, though is not waterproof and its quality control does not seem to be as high in my opinion (though it is about half the price).
