BGA T PC Oasis Reviews

Back to BGA T PC Oasis I Product Reviews

Alexander Bardua, - May 2013

BGA T PC Oasis 8x24
Translated and edited from the original review published on, May 13

"This is the quintessential ‘pocket’ binocular. Double-hinged, it folds down to fit in your hand and has a weight of only 240g.

Mechanically, this binocular is very good. The hinges show just the right amount of resistance. The eyepieces are of the twist-out type and click solidly into place. The adjustment of the dioptre is via a ring around the right eyepiece, so no problems here.

Focussing is smooth and free of slack, let down only by a focussing wheel which could be a bit larger in diameter. Its surface is a bit slippery too so don’t expect ultra fast focussing throughout the range.

Optically, the BGA T PC delivers within its physical limitations and price-point. In broad daylight, the BGA T PC shows a brilliant and contrasty picture full of fine detail. It’s very low on chromatic aberration (CA), which is always a pleasant surprise and the colours shown are quite neutral. The sweet spot is about two thrids of the field of view (FOV), outside this coma and some other aberrations appeared. Pincushion was quite pronounced in this outer third of the FOV. I think that’s a good performance for a binocular of this price.

Two deficiencies were quite visible. The first is glare. Very early when watching against the setting sun, the lower third of the picture is seen through sort of a white veil. An Eden XP 8x42 (of the same price-bracket) was much better in this aspect. So using a spare hand to shade the lenses is a must early in the day or in other backlit viewing conditions.

The second is when looking directly up into a tree. Any bird is but a black silhouette. With better binoculars, I can detect lots of details of the bird, but not so with the BGA T PC. It doesn’t handle that amount of contrast so well.

Being such a small binocular, it starts to fail in low light. This is of course no surprise, as it’s has a 24mm objective lens and an exit pupil of only 3mm. But I did some star-gazing with it and even with this binocular, I was able to see stars not visible to the naked eye.

In direct comparison to the Traveller BGA MG 8x32 (which I reviewed at the same time) when watching the landscape there were some shortcomings visible. Having a look at my favourite target, a church tower some 1000m distant, this was very obvious. The BGA T PC showed the structure of the roof with its slate tiles without a problem and also the cross on top. But the clock face was mushy and the hands were visible but not the numerals.

I had the sun in my back, so the tower’s white plaster was gleaming white. The BGA T PC couldn’t pick out detail and highlights were washed-out. By comparison, the Traveller showed the details in the plaster. The tiles on the roof were better defined and more details were visible on the clock face.

The big problem of this compact binocular (and all others as well) are the too-small eyecups. It’s difficult to put such small instruments to your eyes without black-outs appearing. I tried to improve this by adding some self-adhesive foam I had lying around and you know what? It worked! A couple of mm more to the diameter of the eyecups and eye placement was so much easier. It improved the BGA T PC considerably and makes me wonder why a manufacturer couldn’t add some L-shaped shims to fine-adjust the eyepieces.

So what are the advantages of having an BGA T PC at home? Quite simply, it is not a burden to carry and you have a useable binocular at hand whenever it is needed. I wouldn’t use it when planning to go out birding but as a go-everywhere binocular it beats any alpha left at home. Yes, it has its optical shortcomings when compared to more expensive binoculars, as I found out in direct comparison with a Leica Trinovid 8x20 but not everyone is willing or able to pay that much for a binocular.

The Oasis 8x24 BGA T PC 8x24 is a sound package for the money. The fact that I had to modify the eyecups to be able to use it satisfactorily made me use it without the enthusiasm it deserved. But that goes for all compact binoculars - they don’t fit my face very well. If Opticron would do something to the too-narrow diameter of the eyepieces, then for me it would beat other compact binoculars with regard to practical value."

Glenn Morris FRGS - September 2011

Glenn Morris

I have recently returned from the Arctic having kayaked Arctic Canada's fabled Northwest Passage as part of the Arctic Voice Project; a journey of over 3,000 miles. During this time the team used Opticron binoculars for navigation, assessing the terrain ahead and for wildlife observations. They performed faultlessly despite the tough conditions which included temperatures down to -35 C and liberal dousings of salt water.

On my return, when bird watching, a minor fault developed in one of the lenses. I called Opticron, was dealt with politely and efficiently and within two days the binoculars were returned to me, repaired and ready to go. I would therefore highly recommend both the binoculars and the professional service this company offers.

Many thanks. Glenn Morris. FRGS, Leader of the Arctic Voice Expedition.
