lens help for a new royal from a kenco compare

[CKSCUBA 0]

I have one of those keneco lens . 5 multi crapp lens. it fogs up terrible and is dark image.

i changed to a cheap .5 sony lens and the lens is much clearer is still get a bit of fog but only when i open my parachute and then it stays fogged but the free fall is clear.

i have to fly exactly 2 ft back when i fly with my sony. th kenco lens i could grap the tandems hand and all that and get a great picture. the .5 sony i cant do that and i have to fly 2 ft back then when i fly with the kenco lens.

did you say the diamond lens was best the .5???

my question is if i get the royal lens which size do i get to be comparable to my kenco flying distance is there a way to calculate this??

i fly a sony hc 40

thank you very much

Well...the width of the lens adapter is based in part on the camera you fly, because different cams have different focal lengths at wide. The Royal (or any other lens) .5 will be the closest in angle of view to another .5, but .5 lenses are not all the same. You can easily find 15% of difference in various 180 degree/.5 lenses.

Of the low-cost lenses, I found the Royal to have slighly better resolution than any of the other cheepies. I did not test the Cookie; I'd asked for a lens to test, but a lens was not forthcoming. Next spring when the new trade season hits, I'll likely again test various adapters.
Back to point...you'll need to do at least one skydive to test your distance after changing lenses, unless you've got a measurement plate on your wall (unlikely?)
