Exceptionally good quality and quite large lens. Although the lens is only 10mm dia. larger than its smaller sister (DT120C), that 10mm = 20% larger in area which really makes a difference, just lovely to use.
Personally, I like it not having an extra inset lens, I find them distracting, if you really want an extra closeup lens, select a free pocket magnifier from the list of free gifts.

The Photos
The photos looking through the lens have not been enhanced, this really is the magnification. Because it was broad daylight we forgot to turn the light on, which would have made the image brighter and more spectacular.
Mag, size, WD
Magnification, lens size, working distance.
Be aware that lens size, magnification and working distance are connected. This is due to the laws of physics, it is not a choice, this applies to all simple lenses (i.e. not microscopes and telescopes).
You want the largest lens? A 150mm diameter lens will give a magnification somewhere between about 1.2X and 2X with a working distance somewhere between 250 and 350mm (10 to 14 inches). Ample room to manoeuvre a large object but not very powerful.
You want a powerful lens? 8X magnification will give you a lens of between 15 to 25mm in diameter and a working distance of about 25mm (1 inch).
You want a very large lens with a high magnification? This is not possible with a simple lens. Consider one of the following: a surgeon’s binocular headband magnifier (it uses two small telescopes not ‘simple’ lenses); a low-power bench microscope (but select the lowest magnification) or a video microscope.
