There is also a model with a 30x zoom (iE3035W), another with a 40x zoom (iE4038W); and one with a 35x lens.
Sakar president Jeff Saka said: ‘These days, capturing the moment is only part of the story – sharing it with friends and family wherever they are is just as important.
‘With impeccable optics and ultra-high optical zoom capabilities, these new Polaroid models allow you to get even closer to the action for instantly sharable shots.’
There is no word on UK pricing but, in the US, the 50x model will cost $299.
Last year Nikon accused Sakar International, a US firm, of patent infringement and launched a successful legal action forcing Sakar to stop manufacturing and selling the Polaroid iM1836, an interchangeable-lens camera.
Industry watchers had likened the looks of the Polaroid iM1836 to the Nikon 1 J1/J2 cameras.
