about 5 ft. the only way you can get closer is with a extension tube or close up lens. it would be hard to find 77mm close up lens so you might have to get step down ring say from 77 to 72mm. you might check into an close-up lens nikon 5t or any other brand they screw into the front of the lens which won`t have any lightloss. extension tubes install between camera and lens get the mount for your camera.you will have light loss with extension tubes 1-2 stops. also with the close up lens or extenstion tubes you will not be able to focus out to infinity.

minimum focus is less than 5 feet, seems about 57 inches or maybe as little as 52, I cannot remember. I have occasionally used it for closeups of flowers quite well

The tube makes your depth of field incredibly pronounce. You might want to remove all but the smallest ring. The actual focal length of your lens is fairly close to the actually lens. If you hold an object very close to the lens, you will be able to get the object in focus. For instance, lie the camera down in some grass. It makes the DOF so shallow, that only one or two blades will remain in focus.

Actually it will focus down to 20 ft which is better than 10 meters. Hope this helps.

It has good center sharpness down to about one foot. It still gets a focus down to about 7 inches, and you have to look very closely to realize that the sharpness is falling off a bit. Any closer than 7 inches, it does not focus at all, as far as I can tell.

Yes. You can focus very close, probably about an inch or so from the subject.

Looks like focus down to 4 to 5 feet. Has diopter adjustment. I can focus without my glasses on if i adjust diopterveyepiece. That said, i would not buy that model again. Prefer the green screened nightvision. IR works but not at great distance. Price is good, though.

Minimum focus distance is about 11 inches for the stock Nikon lens if I remember right so if you get any closer you wont get a clear shot. If you want to shoot closer look into a micro/macro lense lens.

You probably mean using extension tubes, which would give you a much closer minimum focusing distance....

I use this 500 mm lens with a Nikon D600. The range of focus is from about 7 feet to infinity.

2.8 is the maximum aperture at minimum zoom. I no longer own thing lens. But I believe it goes to f22. It is either 16 or 22.

This lenses is meant for distance - I believe min is 12'. If you're looking for everyday photos in the home or close distance you don't need this lens. This lens is great for landscape, wildlife etc...

Depends on the lens not camera. Typically a lens like this can focus as close as 10 inches and has maximum magnification of .3x meaning an object must be at least 3x the size of the sensor to fill up the entire screen.

you have focal/focus point,which is what it says.depth of focus is what you can use for average focal/focus. too little makes it hard to stay in focus,too much is all blur.

I've not used them from much more than 30' away. I'm pretty sure you can't get much farther away than that. And that's straight on from the lens. From an angle it's even less

Focus wise it can be as close as less than 6 feet for my eyes (I think it depends on viewer's eyesight). However, the real problem is the images from two eyes don't over lap very well when the object is this close. If you want to observe something that close, Pentax Papilio is designed for that purpose and has very good reputation.

Yes, But because you are using a camera with a smaller sensor your focal range will be approximately 42- 450 mm
