A couple reviews mention a narrow field of vision but no one actually defined what the field of vision is. How wide is the field of vision?

I don't know how to determine the field of vision in terms of feet or yards. My impression was that I saw what I expected, both in range and detail. In fact, I was pleased with the range and the details when I first tried it. It took me a few minutes to get my bearings because this is the first night vision device I've tried. Perhaps to put it in perspective, I stood on my back deck and looked into the approx. 2.5 ft wide by 4 ft high window on my shed which is about 20 yards away--I could a rope inside the shed, window panes, and other objects inside the shed. So, at about 12 to 15 yards I could just see the 2.5' by 4' window missing (blocking out) only a few inches on the height.I hope this helps.

We didn't notice a narrow view. We could see a fifty-foot wide section quite clearly while in regular mode. In zoom mode, we could see to the tops of large trees.

I found this specification: 3.6mm Lens with Viewing Angle of 75°. As others have stated, it is wider than what is commonly found. For the cost, I was not disappointed.

I can't specify "field of view," but what I can tell you - that I think is important for you to know - is that when I replace a 10x eyepiece in my low-power binocular microscope (1x objective), the image is greatly magnified from what it would appear through the eyepiece . . . perhaps about 5x as much (50x total?). I really would have liked it to stay the same, but I can understand why it doesn't. If you have a 40 or 50x eyepiece (or so) that you replace with the camera, my guess is you will see about the same picture as you see through the eyepiece. The clarity is good. Of course, it could be better, but probably not for the same price. Now that I understand the limitations, etc., I am quite pleased with it. I built my own lens and stand for it, using the barrel of a cheap flashlight and a double convex lens that just happened to fit the tube perfectly (24mm). I added a diaphragm to increase depth of field, and a baffle between the lens and camera to minimize "splash" within the tube. These are all held in position within the tube by O-rings (from Harbor Freight). The added diaphragm requires an additional light source, which I got from eBay for $3.50 (music stand LED lights on flex arms). Works pretty good!

You can look as far as you want. I've looked at the moon and saw more detail but that is not its purpose. I would say it is most effective when looking at a specific object under a mile. I have used mine while hunting and most objects are within 500 yards. You should ask yourself what is the main reason for buying the monocular. For sporting events or hunting, it is great but not so great for astronomy.

I have no experience with one other than the built in optical finder. I suppose one of the shoe finders in the 50 to 55mm range made for full frame cameras might give an approximate field of view. I think some are sold under the Voightlander brand name, but watch out for size because some can be large for so small a camera. Sorry I can't be of much help. Don.

A common lens of about 50 mm of focal lenght, cover a landscape of around 50º over all surface of the sensor. But a teleobjective of 500 mm cover an angle 10 times minor. That's to say one can see a very far object of 5º extension over all the surface of the same sensor. That is the magnification.

It's the lens, a 2.8mm will give you the widest possible view, 12 being the closest.

Your aperture is a standard no matter what camera you use. 2.8 is 2.8, regardless of focal length. Technically, your depth of field doesn't change either actually. The 2X crop factor means you need to stand twice as far away to get the same Field of view compared to a 35mm equivalent (full frame), which is why your depth of field will be less. Another way of putting it is that you'll get the depth of field of a 25mm lens with a 50mm equivalent.Also, know that if you're looking for a shallow depth of field with great bokeh, this is the only lens you should be considering.

Give a small area of light just wide to see where you are going on a pitch black trail. I have a higher lumens light attached to my helmet for the technical trails down hill. Field of view is about 5 ft low beam and 7 ft high beam 4 ft circumference.

I really don't believe it would be, it has a very narrow field of view. Of course, it is only my opinion

It depends on what your eyeglass prescription is. I spoke to my optometrist to see Whart general range is.

I wear eye glasses. I could comfortably see the entire field of view with my eyeglasses on. I was pleasantly surprised. I have 1.50 D of astigmatism in my eye, and I could see a clear improvement in sharpness with my glasses on.

I don't know what the angle of vision is (I'm sure it's in the specifications), but a real life example: I have this mounted to look at my back garden, and I can see in good detail around 30ft wide field of view, at around 10ft distance. In other words, I can see around 30ft left-to-right of what's around 10ft away from the camera...

I just tried close focus and it didn't focus closer than 2 ft where the field of view is about 3 quarters wide.

The user guide says that the "field of view is fairly small. It is approximately equivalent to the field of view through the telescope when looking through a typical (i.e. not wide-field) 5mm focal length eyepiece." So maybe 200x ?

If you mean does it have a wider field than normal I didnt notice that it did. Has a sharp picture and seems to respond properly to adjustment clicks. I've used it at 100 yds on 6 inch targets, seems OK with a max 9 magnification.

I am not sure, but I wish they did have a wider view. However, after having my vision corrected to mono vision (one eye for long distance/one for reading) these actually can focus to the degree that I can see clearly though both eyes.
