Test Results


Art. –Nr. RE-SWA-10

Super Wide Angle 10mm



Very good at the center, but drops towards the edges

x-axis: distance from optical axis in °, y-axis: resolution in arc minutes


Apparent Field of View:

Our measurement gives 69° - close to the manufacturer data.



Very good.



Noticeable cushion distortion as well as field curvature.


Eye Relief:

Very short eye relief. To have a view of the complete apparent field you may prefer to remove the rubber eye cap.


Mechanical Quality:

Good quality with rubber eye guard, grip coated body. Fully multicoated and well blackened inside.



You can not use the full apparent field of view in good optical quality. However, as the field is much larger than for Plossl eyepieces, there is an advantage at a more or less equal price. Edge quality is enhanced remarkably when combining this eyepiece with a Barlow lens.
