P3D Re: Hastings triplet for red button

I just tried putting Hastings Triplets in my Kodaslide I, and the centers were very beautifully sharp, but the edges were greatly distorted.  I don't think it would be any different in a red
button.  I ended up sending my lenses back to Edmund Scientific.

Hope this helps,

Grant
