decided to see if I could beat that.\u00a0 Granted my lens has a fixed aperature of about f8.0 and can&#8217;t actually be focused\u00a0and it&#8217;s 55mmish focal length works out to about 82mm on an APSc camera.\u00a0 So let me just recap here it&#8217;s an 82mm equivelent f8.0 fixed focus lens, but it is <strong><em>really<\/em><\/strong> thin.<\/p>\n<p><span class=\"frame-outer  alignnone

tell you that taking pictures with a cracker is ridiculous (I will have to try that though) and that it does indeed work.\u00a0\u00a0Keep in mind this is the\u00a0Mark I version and by the time I get to the Mark\u00a0IV it will be amazing with all the latest technology (we&#8217;re still on the Internet right?)\u00a0\u00a0 That or I will just build something else entirely which seems more
