    Question on the 10x30 IS

    Good test. Henry's assumption does make sense because the Canon 8x25 IS doesn't state it has field flatteners at all and it has a 4 element eyepiece, whereas, the 10x30 IS and 12x36 II IS state they have doublet field flatteners but yet they only have ONE more element in their eyepiece at 5...

    Question on the 10x30 IS

    "and the notion that somebody should take this up with Canon, perhaps in the Courts, is quite ludicrous." The point is Canon has it circulated all over the internet that the 10x30 IS has doublet field flatteners and if it is untrue it is a blatant case of what they call "false advertising"...

    Question on the 10x30 IS

    I can't imagine why Canon would lie about how many doublet field-flatteners they have in their lenses. Plus it is illegal and somebody could report them to the FTC. I don't think they are that stupid! Plus what have they got to gain? I don't think anybody is not going to buy their binoculars...

    Question on the 10x30 IS

    I have had almost all of the Canon IS's over the years and I recently acquired a new 10x30 IS because I value them for their ability to see detail. Even though your 10x42 SE has no doubt better optics concerning CA and contrast and stuff like that the Canon has good optics and with the IS...
