And we now synonymous know how we can unlock the! Wow! I've bought in any case ever seen a 5 liter cans red color at the hardware store and make myself afterwards a.Capable work. \u003cbr /\u003e\u003cbr /\u003e I would be interested by the way, if you by the width of the red slash may not be synonymous can raise the focal length of the lens. So why not from the small 50mm, 250mm 1:1.8 make one with this Lichtstaerke? \u003cbr /\u003e\u003cbr /\u003e The weekend will be saved ...

The real secret is transparent varnish. Since then more light falls through the ring and the light is stronger Objectively. \u003cbr /\u003e\u003cbr /\u003e I did so with all my Canon lenses (synonymous with those who had had this weird red rings) to win again at least half an f-stop. \u003cbr /\u003e\u003cbr /\u003e\u003cbr /\u003e But ATTENTION, two references before you make it yourselves: \u003cbr /\u003e\u003cbr /\u003e First nacher is no longer the aperture ring label. But you can easily handlen with an app that converts an aperture values. \u003cbr /\u003e\u003cbr /\u003e And secondly, do not use any no-name paint, but only with a UV filter.

Listens to maybe stupid, but agrees with the radioactivity of the bright lens? I've already found several video sites and synonymous to it. That would be yes, to put it mildly, a disaster.

This is not allowed by the rules, but it has occurred. When the Eye in the vicinity of a thorium-eyepiece is positioned, the dose may be significant to the eye of the outside fabric. Casarett et al assumed that an individual used an eyepiece with 16% thorium for 20 hours per week, is estimated to a dose of 44 rad at a depth of 50 microns and 18 rad to a depth of 60th With a goodness of 20, it would at 880 and 360 rem rem per year, or equated. Similar calculations of McMillan and Horne were in general agreement with these figures. A measurement, a theoretical calculation showed a contrast dose of about 1 mrad / h A.The surface an eyepiece with 18% thorium. \u003cbr /\u003e\u003cbr/> NUREG-1717 estimated that the dose for the operator of a television camera with thoriated lenses could as much as 60 mrem per year. This assumes that the three-Camera Lenses contain 30 wt% thorium and that the camera is positioned behind the camera man for 1000 hours per year. Nevertheless, there are noHinweise that are frequently used in thoriated Lenses TV cameras. \u003cbr /\u003e\u003cbr /\u003e Measurements have shown that the radiation exposure in a depth of 10 cm in the body of an individual carries a camera with 0.36 uCi of thorium about 0.01 mrem / h would be. This value is calculated based on NUREG-1717, that a serious photographer could a yearly load of 2 mrem received. This assumes that the photographer's camera carried out 30 days per year and for 6 hours per day. Beyond
