|See, I'm just the opposite until I looked closely I never realized there was a 6-4 formula ? I knew about the 6-5 and 7-6 because of the 50 1.4 II which impulsively made me look a while back, what the differences were and that's how I discovered about the 6-5 and 7-6 formulas back then, never really gave any thought or explored further.
Pacific Rim Camera has info on them, not much but pictures of each displayed. I never really used my electronic scale for a lens before, I did weigh it 3 times though with no variance?
It just seems that a 6-4 formula would logically weigh less than a 6-5? Maybe, since Canon does not have the weight for the 6-5 formula listed ...they have it backwards? The missing weight is the 6-4 and 280g is for the 6-5 formula they think is missing? Or.... 30% Thorium Oxide sand in elements creates one dense glass compound considering a 6-5 formula weighs 20 grams less?
It just seems so easy to think again about trivial things such as this, knowing the evil Emperor has been dethroned puts my mind at ease to be trivial again I guess... like a war is over?
