If you are mounting this behind a glass window, how far away from the glass should the lens be?

I did not try doing that. I'm assuming this is a special glass which will not reflect back at the lens or cause any distortion. If this glass is meant to be like a protective cover in front of the projector, just maintain (in my opinion) around 10-12 inches of distance. The lamp cooling fans are in front so you'd like to leave space for efficient air flow.

Are you referring to the wide angle and telephoto lens? those should be mounted on the front of the 18-55mm lens not on the camera.

You should be at least 15 ft from your home and not under any windows. Make sure that your exhuast is pointed away from your home. Hope that this helps

Hi, The focusing distance is always measured from the sensor. Therefore, subtract the distance from the sensor to the front of the lens barrel (approximately 3 inches), and you are left with actual "working distance" of about an inch. Hope that helps.

YES, Minimum Focusing Distance: 1yds. YES, IF YOU CAN USE IT WITH GLASSES.YES, YOU CAN USE IT WITHOUT GLASSES.

I'll have to measure my lights, but that sounds pretty close to the overall distance from lens to lamp socket so depth would be determined by how for you want them to stick out past the mounting flange.

Depends on a lot of factorsHow far away, point of position to the objectU have always distortions ! There is no lens w/o

Not sure what you are asking. The projector is attached to the lens. Are you asking the distance from the mount to the lens?

I don't have one on my camera, so I can't be completely sure. But there is some extra room in the case in front if the lense. I would say probably 4-6mm of extra space maybe.

Just opened it and installed a battery (not included). I find it focuses best at about 4" and is clear enough about the entire window. It should work well for your purposes.

Well heck I guess you could put it anywhere really, within range of the sensor. I had it in a window for several days before putting it up and it went off every time I walked by, a distance of a good 3-4 feet or so with a ~45 degree cone. Once I put it on the shed I mounted it directly above the door, and it goes off every time I reach the doors. That height is about 7 feet.

It would need to be close to a window for ventilation. Its suggested to be no more then 4 feet away from the vent source.

The lens is not glass. You should be able to very carefully remove the lenses.

I used it with a 150mm lens but it still had some shadowing so I would say anything under 150mm is not going to work well.

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

I'm using this lens for long range stills... like a shot of a full moon I have it mounted on a Nikon D3100 with a doubler 2X making it a 1000mm Zoom lens. The first thing I noticed was that I couldn't hold it still enough to take a picture without some sort of stabilizer (recommend a tripod), the second thing is the light was really low, which for my purpose was perfect. I haven't tried it for any moving objects.

The distance from the center of the 15mm rod to the center of the lens opening is adjustable between about 3.75 inches to 4.5 in. You just need to take a ruler to your rig and see if this your distance falls within that range. I got my matte box out and measured it. I just hell up a ruler so I could be off a little.
