"But please, Dan and Craig, do point to something factual I can read that tells me why I'm all wrong."
To be honest, I don't have the documentation I can share with you. I don't blame you for not trusting me. I know that you don't know me and don't know my experience in optics, still and motion film imaging, and video production. I've been as factual as I can be based on my experience with lenses costing $50 to $35K and intermixing them with imagers they were not designed for. I suppose that I have not taken enough time to carefully detail all the exact lens qualities that are involved, nor the scientific reasons behind them and probably should not chime in when I am not prepared to do so. Since I am perceived as unknowledgeable in this area and I do not have the time to write lengthy replies to prove so, I will reserve myself at this time. I do look forward to better lenses for a cheaper price and have no doubt that they will happen. They can't come soon enough for me!
