Two cheap digital lups from China.
They do differ quite a bit both in res and focal point.
Tearshape, needs to lay on what you wanna enlarge, and can also record video with a small sdcard, do have some memory on board (without added SD card) but is only valid for a limited amount of pictures.
The other unit got focal point, around 2 cm out, and will only do pictures with an added SDcard.
I like them a lot, very convenient way to enlarge smaller things.
price is around 12 to 15€ (incl. 25% EUVAT)
