What is the depth of field on this. What range is in focus? One of the pictures shows it looking out a window at building that seems to be in focus.

I don't disagree that it is intended for close objects. That being said, the image at distance is remarkably clear.

It's definitely not that far. It's designed to be used in close areas. It works great for inspection type stuff, in wales etc.

What I know is what they do in practice. The focus is fixed, and I have seen clear video as close as two feet, and as far as 40 feet. What I do not know are the exact specs.

You can focus on objects as close as 1.5 feet. For distance viewing, it brings everything 6-8 times closer depending on which model you get.

I'm assuming your referring to beam focus or dispersion. I don't have exact degree but this is more of a narrow focus beam. Probably no more than 20 degrees.

There is focus adjustment on the back end for adjusting ranges ... set it a 50 yards and mid-magnification and adjust if I need to for really close and over 100

I am amazed how clear and sharp the photos are at a distance of 100' plus during day light hours. At night it's a different story. The subject has to be fairly near to get a good picture. I would guess between 25 to 50 feet.

I have found it best at 15 to approx. 40 ft. Up close it seems to blur.But, I am more than pleased with the Moultree D-444.

It had a big depth of field. Everything was in focus from a few inches to a few feet.

My experience is that it adjusts the focal length and this the magnification increased, but you must move the subject closer or farther from the end. You may have to move the small object into the window if it comes into focus. Depth of field gets very tight at higher mag.

They focus very well. They have a focus adjuster that is simple to us. Its on top and moves left and right. I was looking out on the ocean and it focused wherever I wanted it to

It's the lens. If you shoot wide open you get a beautiful effect in the out of focus areas. You just have to be careful to focus carefully on what you want in focus. The depth of field at f1.2 or f1.4 is very shallow.

It's a microscope, so it seems to work best close up; otherwise you don't have magnification. With that said, I can focus in the lower magnification on an object about 1 meter away, but it isn't really magnified. The higher magnification requires me to be almost touching to focus. This isn't very scientific, I don't know enough about lens math to be, so I just tried it out around the room.

Using another spyglass viewing a yardstick and doing a little math I came up with 145' at 1000 ft which would be 450' at 1000 yds. A quick test against my Mom's similar $135 device, including the 10" focus ability, showed no visible difference to me. I do wish it had a rubber eye cup, though.

I think it's very good as long as it is not facing a window. Sunlight coming in distorts the picture but the outside camera works great, I don't really understand that but over all I think the image is good.

There is no focus. It is just a magnifier of your view screen. I love mine. Great for a sunny shoot-bloks out excess light so I can see my screen.

Close focus is 25 feet, a little fuzzy at 20 ft. I use mine to spot bullet holes in a target when shooting with iron sights at 50 yards. Works great!

I'm not sure if I understand your concern of DOF issue with 1.8, but you can always change your aperture to 8~9 and it will show details of your back-ground. But If I were you I would take a 18-200mm instead. covering wide to fairly good zoom unless you are planning to do dark inside building pics. That's just my 2 cents.
