What is the magnification factor of this lens?

Not sure what the magnification is. It is used in place of a macro lens, most often on a 70-200mm or 200mm prime lens when traveling so as not to have to carry extra lenses . The same principles apply when using the attachment for a close up shot, a tripod and cable release are essential. A macro rail system would also be helpful but not an absolute necessity. Hope ths helps.

The magnification with my 18 to 55mm zoom lens set at 55mm is 6X. The distance frim the subject is about 4 inches.

The lens is about 5 inches in diameter. I actually bought this for my mother, who crochets and does needlework. She loves it and has no complaints about it.

No lenses do this.An f2.8 lens when racked out from infinity to 1:1 magnification is by definition working at f5.6.The number is the ratio of the distance from the sensor to the aperture divided by the diameter of the aperture.At infinity the aperture is basically 105mm from the sensor (simple lens approximation).At 1:1 the aperture is basically 210mm from the sensor.So the aperture is roughly halved.http://en.wikipedia.org/wiki/F-number#Working_f-number

Cannot tell specifically. If you want large magnification, you need to insert the object inside the clear plastic area. It is not even half of stated zoom otherwise. It does a decent job for the price.

It is a 500mm lens with a 2x adapter. Manual focus and at f/8 really only good with lots of light. But fun to play around with and compact in size, limited uses.

1.75x. Working distance is around 6-12". You'd never do that with a 5x magnification.

2.25X according to the Amazon.com listed description. I got it for my wife. She loves it! To me, it has more than enough magnification.

Yes, it will be affected by the 1.6 magnification factor though. It is now my favorite lens.

Many lenses are described as having "macro" capabilities, but this only refers to their close-focus distance and magnification. A true macro has 1:1 magnification; the 35-70 was 1:5.6, and the 24-70 is a little better at 1:3.7, but neither are true macros.

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.

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.

No magnification and its slightly smaller than an iPad. Hope that helps. I really like it .

This lens can focus down to about 3/4" from the end of the lens, a distance that makes the distance between the subject and the sensor inside the camera about 4 inches. In practical use, one must get very close to their subject to get the maximum magnification, which for some might make this lens impractical. I use this lens not only for macro use, but as the standard lens which stays on my camera most of the time, it does very well in all situations and it is very sharp.

It can focus pretty close at all focal lengths, but it doesn't have a formal "macro" position. There's a discussion of this on cameralabs site, see the review of this lens. He claims a magnification ratio of 1:2.6 is possible. I haven't measured it myself, but it is a good lens for closeups.

650-1300mm f8.0-16.0 86mm diameter lens. Almost 2kg weight. Manual focus. Mount for tripod.

Each of the focal lengths for the 4 lenses are listed below: 1.5x Lens: 19.7 inches 2.0x Lens: 9.8 inches 2.5x Lens: 6.6 inches 3.0x Lens: 4.9 inches Please note that the focal length does not mean that you must hold the magnifier that far away from the object. It just means that's about the distance where the magnifier has its highest magnifying power.
