Helios 10x50 AQUILA HR Waterproof Porro Prism Binoculars

The Helios 10x50 AQUILA HR Waterproof Porro Prism Binoculars have a close focus range of about 5 metres and although not quite as close as the 8.5x42's, the 10x magnification and increased objective lens size more than compensate for this lack. The 10x50 AQUILA binoculars boast a 6.0° field of view makes the tracking of birds on the wing easy, even for this powerful magnification and with the 50mm objective the 5mm exit pupil returns bright images whatever the light conditions.
