Tasco 124 7x50

Mfr: J-B22, J-E29

Date: circa 1960's

AFOV: ~77 degrees

TFOV: ~11 degrees

Eye Relief: ~13mm

Prisms: high index

The Tasco 124 is an extra wide angle 7x50 nicely finished with silver trim.  Note the "Extra Wide Angle" engraved around the objectives.  It also has screw-down plastic eyecups. 

The exit pupil on this binocular is nearly round, with some slight vignetting from the body of a prism.  There is some prism leakage noticeable.  The optical field has quite a bit of astigmatism towards the edge, but on the positive side the field stop is easy to see, providing comfortable viewing without glasses.  Though the eye relief is better than average for such a wide angle, it isn't enough to comfortably use with glasses.  On the whole, I much prefer this model to the Tasco 420 which has a similar field of view but less eye relief.
