<p>@<a name="00cbO2"></a><a href="/photodb/user?user_id=2403817">Rodeo Joe</a> I especially signed up to respond to your answer, because most parts are so totally wrong and mistaken...<br /> "multi-coating applied was intended to cancel out any slight colouration of the glass used" is complete nonsense, the light reflected is because of the coating thickness<br /> don't believe me but check; <a href="http://rick_oleson.tripod.com/index-166.html">http://rick_oleson.tripod.com/index-166.html</a><br /> and "softer glass" absorbing coating... really? come on man...<br>
ow yes; magnesium fluoride (which has a refractive index of 1.38) because it’s relatively cheap, <strong>easy to apply</strong>, and gives a hard scratch resistant surface. http://www.canonrumors.com/tech-articles/all-about-lens-coatings/<br>
actually ALL the info you provide here is incorrect....</p>
