I believe an Imagic in various guises has been a mainstay of the Opticron catalogue for around 20 years. It is possibly the most common model of any make I see at our local reserve. Not surprisingly the new VHD incarnation has sparked quite a lot of interest on the forum, especially as it’s close relative, the Tract Toric x42s in the US has received so much attention as well.
While the last BGA Imagic SE x42s morphed into the Verano HD for a while, the 8.5 and 10x50 featured unchanged in the Opticron catalogue for 10 years. Last year, together with it’s smaller siblings, they got revised as the VHD. Outwardly It looks like nothing had changed. Indeed the spec sheet was unaltered as well. There is some rewording in the product features, but I think you might be forgiven for missing that there was anything new on offer there as well, other than the VHD label. So what is new? The Opticron strapline is “Smaller, Lighter, Brighter Sharper". The old model ticked the first two boxes nicely. These x50s tick all four.
Visiting various retailers over the past year I’ve managed to check out most of the new products from Opticron, but the Imagic VHD x50s had eluded me. I particularly need to thank Pete Gamby for lending me these two binoculars.

The binoculars come with strapless case, which I found a good fit. Fine for travelling, but best left in the car. The press over stud fastening worked fine while I had them, but I’m not sure how secure it would be in the long term. The rain guard is the usual, fairly stiff, Opticron design, which I find a bit fiddly to put on with narrow IPDs, but stays put and easily removed for use. I didn’t fit the strap or anchored objective covers for the time I had them.
The “Smaller, Lighter” part of the tag seems particularly apt for these models. They may be 76mm/6.9” long but they sit in the hand like a fairly compact x42s. Indeed the top half is very much like the x42 Imagics, only flaring out to accommodate the 50mm objective gradually. This obviously makes it much more manageable for smaller hands. The armour compound appears fairly smooth at first glance, but is in fact finely textured and quite grippy. The compound seems more flexible, or perhaps it’s just thinner than some, which would help to keep the diameter and weight down but perhaps a little less protection? I’ve recently learned that binoculars can be miscollimated very easily by a over excited three year old? There is a temptation to just hold these binoculars at the narrow end, but that makes them a bit nose heavy and unbalanced I feel. I find the steadier grip is to have one hand near the top for focus and the other and the other nearer the objective.
At under 800g/28oz they must be amongst the lightest x50s on the market. It’s more than 260g/9oz lighter than the last x50 I reviewed and 35% lighter than another I own. While more weight can mean a steadier view in the short term, these would be much less tiring and easier on the neck over the course of a day. In fact these these are pretty much the same weight as the x42s I normally use.
There is a difference in the focus tension between these two samples. The 8.5x50 is the slightly stiffer of the two and perhaps less likely to overshoot the mark than the 10x50, but I personally prefer the faster action of the latter. I don’t imagine these are design differences, just sample variation. The focus action is very fast with close focus to 5m taking about 60° anticlockwise, and from 5m to infinity about 220°. The spec sheet lists 3.5m/11.5ft for close focus, but the 10x50 did better better at 3.05m/10ft. The speed, particularly when combined with the light focus of the 10x gives it fingertip control that I prefer. The dioptre adjustment is on the right eyepiece and is simply held by friction. Again there is a difference in the turning resistance, this time the 8.5x seems a little on the low side to be totally secure. The zero position was also a long way out on the 8.5x50. The IPD range is listed as 58-74mm but was just 0.5 wider on my ruler.
I know some of those that wear glasses will note the listed 23mm eye relief with some interest and those who don’t might despair. I actually measured it at a still generous 21mm which is more in keeping with the lens dimensions and field of view. The measurement from the rim of the fully collapsed eye cup to the ER was 17mm, and 6.5mm fully extended. There are two ratcheted intermediate eye cup positions at 2.5 and 7mm extended. As is usually the case, none of these positions worked particularly well for me. I would need to source some O-rings for an intermediate position with glasses or hold the binocular slightly away from my face without. I’m sure others will be luckier.
In order to keep the barrels slim and the weight down, it seems that Opticron have opted for a smallish prism size which has a consequence for the field of view. The focus cap of the 8.5x50 is labelled 6° and the 10x50 5.8°. In fact my estimate for both was identical at 5.87° which would be 102m@1000m or 306ft at 100yds. The 58° AFOV of the 10x50 may not compete the widest views on the market but I found it quite acceptable. The 8.5x50 with 50° on the other hand, is definitely on the narrow side. Of course the view is a bit steadier than the 10x, and the quality of the view might still be quite persuasive.
Having ticked the Smaller and Lighter boxes, it’s the turn of Brighter and Sharper. I’ve not done a direct comparison with the previous model, but it’s very obvious indeed that the coatings have had a major overhaul. The colour rendition is excellent. The blue is quite noticeably stronger than in the past and the transmission seems pretty flat with maybe just a bit of rounding off in the longer red wavelengths. I personally much prefer this to the colour bias of some premium models, and these impressed me more than the Imagic x42s when I tried them, I don’t have any numbers for transmission levels but in the gloomy conditions we’ve had since new year, they have has been perceptually brighter than other binoculars I own. I think this is mostly due to better colour. Unfortunately I was unable to test these by moonlight.
The two binoculars I normally use for comparison when reviewing are no slouch when it comes to sharpness, but both these Imagics are better still…. most of the time. There will always be light conditions that favours one binocular or another. The illuminating light and response of the eye will bring different characteristics into play, but given a little bit of sunshine, these VHDs really do sparkle. The absolute limit of detail will be determined by the users eyesight, but both these binoculars were able to bring out plumage detail and textural patterning I’d missed with the reference binoculars. Add in the improved colour and I’ve found these a real pleasure to use. I should point out that when the conditions were gloomy, I thought the 10x brought out the finest detail a little better than the 8.5x. I’ll probably post a bit more about the resolution and technicalities another time.
I do not have the Imagic VHD x42s for comparison, but the view characteristics of these do seem a little different. It might be due to the narrower FOV, but the field curvature seems more pronounced with these x50s. In lower light levels when the pupil of the eye dilates the sweet spot does shrink a little and the depth of field seem shallower than its smaller siblings. This will probably be less obvious to younger users with better focal accommodation.
It took me a while to make some sense of what’s happening with regard to CA. Most of the time it appeared absent, but then it would suddenly appear and mar the view. It turns sometimes it was my fault. The larger diameter eye cups and profile of the molding meant the binoculars did not always sit squarely against my glasses and I was looking through the edge of the exit pupil. Others with other frame designs and IPDs may not have that issue but it’s worth checking. I won't go into all the details here, but I still found at lower light levels, features tangential to the edge of the field of view can be subject to quite strong lateral colour fringing. We know from the forum that individuals do vary in their sensitivity to CA, and this may be a trivial issue for others.
As I said at the start, both the 8.5 and 10x50 tick all the Smaller, Lighter, Brighter, Sharper boxes. I personally prefer them to the x42s that have been reviewed by others here. But they aren’t perfect. There were a couple minor niggles about the build of the 8.5x50 which were absent on the 10x50 so perhaps I was just unlucky with that sample. Some will find the 50° AFOV on the 8.5x rather narrow, and I would personally wish for a bit better CA control. Obviously others will have their own priorities, but I can forgive all of that when the colour and sharpness is this good. I’ve not been able to make any direct comparisons to other mid priced models, and I’m actually struggling to think of another x50 I’ve seen in this price category. There will be x42s which are smaller, possibly lighter, offering wider views and may have better CA control, but I can't think think of one that betters these for both colour and sharpness.
Of the two, I preferred the 10x50. It was a real pleasure to use both across the lakes of the local nature reserve or tracking along the hedgerows around where I live. The ability to switch from a chaffinch at 20yards to a buzzard at a mile away with just a flick of finger was particularly pleasing. The low sun at can be challenging at this time of the year. These were untroubled even by blinding levels of glare off the water which were a total whiteout with one of my other binoculars. I can’t claim that I could pick out the eye of a tufted duck at greater range than I could with my own binocular, but the yellow gleam was much more obvious and better defined. The complex patterning of the greylag breast feathers at about 70 yards again gave the Imagics another clear advantage. The weather has meant that I haven’t really been able to determine the low light advantage of this 10x50 over my usual 10x42 works in field conditions, but it’s obviously there from backyard viewing.
I have done some further bench test and waiting for answers to a couple of technical questions, so there may be a bit more to add at some point. I returned the binoculars when I picked up my re collimated Classics, but would be happy to answer any questions I can.
