Hello, I wonder if someone can help me choose the best option, narrow these two binoculars. ( Nikon Monarch 5 16x56 Vs Vortex 15x56mm HD kaibab ) Thanks. . .:t:
I realise you chose the Nikon but hope the following review is of interest to anyone else thinking of going big...
We have a truck with a ‘wildlife viewing’ hatch in the roof that lends itself particularly well to binocular use. Additionally, we often use bicycles to explore areas – or walk for miles. Our choice of optics is influenced heavily by these particular styles of use. For the best part of a couple of decades, in spite of troublesome portability, I stuck with a scope for long-distance viewing before finally succumbing to the reality that persisting with a large scope and tripod, in our circumstances, was at best inconvenient. At worst I found myself ever-increasingly just not being bothered to use it. I sold it and started the quest for a high-power binocular to fill the long-distance / fine-detail work gap.
I have settled with the Monarch 5 16x56 and I’m impressed. I’ve used the 16x56 for about two weeks now in various landscapes including estuarine, coastal, woodland, and open moorland. I’ve also used it in varying light conditions from bright and clear sunny days to dull grey days, and well into twilight. In all cases the image is bright and the resolution is good. Colour fidelity seems faithful and the level of detail and 3 dimensional advantage that comes with the benefit of binocular vision is very rewarding when compared to ‘one-eyeing’ it through a scope. Colour fringing is generally well controlled; however, if looking at high contrast targets (today a cormorant in a dead tree backed by open grey sky), and if purposefully trying, I can pick out some aberration towards the periphery the image. I haven’t been aware of ‘shadows’ (unlike in a Duovid I briefly tried) and rolling ball and engineered distortion do not, to my eyes, present as an issue.
The field of view is claimed at 72x/1000x (4.1°) but given the limitation imposed by the 16x56 spec I find this perfectly acceptable. I have been able to lock straight on to wildfowl in flight without any trouble. In use, I find I am not even slightly aware of a restricted field; such is the intoxication of marvelling at the extraordinary detail. The field of view is better than a 15x45 Zeiss Conquest I tried which (as a deal breaker) also suffered from serious glare/flare issues.
Image with the Monarch 5 is sharp, but careful focus is critical. I find this necessarily-very-precise-focus ‘issue’ the same with our Monarch 7 10x30, one barely discernible turn of the focus knob is the difference between a good image and something altogether too fuzzy to be fun: depth of field is not that great. Fortunately the focus knob is very smooth and is utterly free of stickiness and slack. Dioptre control is on the right eyepiece and though not lockable takes some shifting – so accidental adjustment is not an issue.
Eyepieces are multi position-able twist out affairs with good solid detents. Here’s a weird thing; they are so big that even when fully twisted in, their perimeter interferes with the bony parts of my nose and brow (when the IPD is set correctly for me) and thereby holds the eyepiece lenses at just about the perfect distance to accommodate the (claimed 16.4mm) eye relief. It would require a user with a very narrow nose bridge coupled with a very wide IPD to need to wind the eyepieces fully out, or even out past the first detent.
A consequence of this is that if there is any bright source of light perpendicular with, or towards the rear of the viewer, a bit of errant reflection in the eyepieces can crop up. This is because the eyecups, unless you are a Bigfoot, can not be deployed and therefore can not shield out problematic light. The issue is no worse than what happens when using binoculars with glasses, but it is something to be aware of. Speaking of glasses, I can use this binocular with my readers on – a full field of view is easily obtainable.
Grip is good thanks to nicely tactile rubber armour and – unlike with the 10x30 Monarch 7s we have – the strap mounting lug ‘flares’ and associated contours make far more ergonomic sense. They are huge and accommodate my preferred grip well. Weight is not as troublesome as might be expected and a couple of days ago I wore and used the instrument for 5 hours straight without any problems (I do participate in endurance sports mind, and keep pretty fit). Helping with this is the neoprene strap which has a bit of ‘give’ and so effectively adds a suspension element and stops a good deal of the bumping and jarring that can occur, especially when walking quickly.
Our main intended use for this binocular is for gazing out of the top of the truck where bracing by resting elbows on the roof is quite straightforward. It’s a hugely pleasant surprise, then, to learn that free-handing is also a very viable proposition. The Monarch’s balance is nice and the aforementioned tactile armour and flares mean that a good solid grip is possible which lends itself to reasonable stability. I can hold the binocular still enough for long enough to mean that I haven’t yet encountered any wildlife viewing challenges where I have missed detail for the want of the stability of a 7x-8x. Of course, it would be crass to claim that a 16x is jiggle free, it isn’t, but it is much better than I had imagined and in all seriousness I am OK with this binocular for a long day out in a variety of habitats. It is, incidentally, awesome to watch small, traditionally shy birds, rendered bigger than your own head! For anyone who knows they will be sedentary for a while, there is also a tripod adapter supplied as standard which is a nice piece of kit and which screws neatly into the front of the bridge hinge.
In terms of handling, as a comparison, the Duovid that I mentioned above was not that well balanced, had barrel contours that worked against my preferred grip, and was altogether just awkward to hold without a fight. Of course, this is a very subjective view and others may find the balance and ergonomics of the Leica far more preferable.
The 16x magnification coupled with 56mm objective lenses and decent quality optics of the Monarch 5 mean that in spite of a small exit pupil this binocular is also pretty good in poor light. For example, I looked out over some arable land with the naked eye and couldn’t see any wildlife interest. Pulling up the Monarch 5 revealed good detail on two roe deer and enough detail of a lagomorph to identify it as a brown hare. Reverting to naked sight I once again could see absolutely nothing, not even dark spots where I then knew the animals were. The 3.5mm exit pupil is never going to make a night-vision instrument, but once again I’ve been pleasantly surprised.
The M5 16x56 is not a direct replacement for a high-powered scope and it isn’t without some compromise. It is, though, definitely a very useful and eminently portable instrument that will get far more use than I had even optimistically envisioned.
As a PS. The binocular we have was the second 16x56 I tried. The first (as delivered from Amazon) had a few faults. The bridge hinge was loose, there was a tiny foreign object in the left barrel, there was a slight burr on one of the objective lens fixing and I had to set the (right eye) dioptre to a positive value where every other instrument I’ve ever had / tried has to be set to a negative. I have no idea if this was just a one off or if it speaks of a more general quality control issue.
