what is the maximum magnification of the Neo-Lucida?

The size of the image depends on the distance between the Neo-Lucida and the drawing surface; the further the paper from the lens, the larger the image will be. In practical terms, this is limited by the distance you can reach while looking through the viewer. Since that varies with the length of the user's arm, It's difficult to give a more exact answer.

Eye relief is unlimited due to being 1x. Even at indirect view. As long as the dot is on target Use mine at about 8 inches.

I can't give a technical answer, but I believe it's magnifies at about a 2X. That is, an object in a normal 35mm picture would get twice as large. Not much of a zoom; may have most value in framing.

The working area is about 1.5 X 1.5 cm, with 1 cm working distance. If the working area is 17cm, the magnification is little. :-)

3x is the max magnification. It's like a normal magnifying glass. As you move it closer or further from your eyes it will increase and decrease the amount of observed magnification.

While the 71008 may or may not be adjustable the 71012 is from 25x to 100x. My purchase has been a real source of joy, excitement, learning and revealing! My children frequently use them for lunar observing. My wife loves animal watching. One suggestion if I may. Purchase a quality tripod! The glasses are not light and for higher magnifications a good solid mount is a must in order to keep your objective is sight. It's well worth the money! I hope this helps and I hope you enjoy your glasses witchever way you choose to go.

Joyce, there's nothing listed on the magnifier itself. I'm fairly certain it's about 3x magnification, with a "spot"of about 5x. Hope this helps.

The Swi-View has a relatively large loupe. It replaced a cheaper hood/loupe combo, which had a 3X loupe, but it was smaller. I have no trouble seeing the entire 3" screen on my Canon 60Da with the Swi-View. I also like the way it attaches (actually "slides onto") the screen. I use it almost 100% of the time for astroimaging, particularly for focusing the optic, using the 5x or 10x mag feature of the 60Da's screen.

With the lightest magnification I would say 10-12 inches. Using stronger magnification you have to be right on top of it.

The 21061 will not pull in as much light and not match the magifixation the 114 can resulting in a lesser view. The 114 would be about the least focal length and apiture I would go.

Best estimation is that the magnifying glass focuses at between 1 and 1 1/2 inches from the object being magnified.

Authentic camera lucidas (like the NeoLucida) are known for producing fairly small portraits, such as would fit on the page of a sketchbook. That said, if you want to produce a larger image, then (1) move closer to your portrait subject, and (2) extend the eyepiece further away from your drawing surface. The distance between your eye and your pencil-point is the main limit on the size of your drawings. Interestingly, a larger prism wouldn't help -- it just increases the likelihood of errors in your drawing. In fact, the NeoLucida is truly ideal for producing miniatures. Great masters like Jean-Auguste Dominique Ingres used this small size to great effect. In his book "Secret Knowledge", David Hockney expresses his astonishment at the unnaturally small size of Ingres' portraits, which seemed almost magical as a result -- as if they were drawn by elves.

The one I've purchased is not powerful enough to do that. Amazon has some models that have higher magnification, but be prepared to spend more.

I would expect at very low magnification you would see something like a lower 1/3 cowitness possibly but as magnification increases should be minimal if any distraction from it.

It means the magnification is 2 1/2 times greater than what you see with the naked eye. The image is 2 1/2 times bigger than its actual size.

With a reversed 50 mm lensa you'll get a magnification factor of about 0.4X. In other words, the linear dimensions of the sensor image will be about 0.4 times the real dimensions. That's quite enough for coins and such; not so good for small insects.

The minimum focus distance is 0.15m. At that distance the magnification should be at least 1:1.
