This is going to be a short review. I purchased this Opticron 12 x 50 Porro from Amazon some time ago and only recently opened the package. Unfortunately, when I began looking through it, I quickly realised that the unit was not collimated properly as I was unable to merge the images satisfactorily. A star test after dark confirmed my suspicions. What I can report is my ‘monocular’ impressions only. Like the several other models in the Adventurer T WP series, it offers up nice, contrasty images with good control of glare. Internal reflections were kept at bay too. I only detected a very minor reflection while observing the full Moon. It has a fairly narrow but well-corrected field of view though at 5.4 degrees. The sweet spot is decently large, with mild field curvature and moderate pincushion distortion creeping in near the field stops. Colour correction is very good for this non-ED 12x model but can be picked up on high contrast targets in poor lighting conditions.
It’s a pity the instrument was received with the optics out of alignment as otherwise it seems to be a very decent performer for the modest price paid. With a two-year warranty from Opticron, I will send it back for either a repair or a replacement. It does however, serve to illustrate another general trend in binocular optics: higher power models are more difficult to collimate accurately than those employing lower magnifications.
