dr bob, you have got it. Donald may be correct (it would take a team of experts years and there would probably never be final conclusion) a WELL made condenser may produce a better image - to the collector/potential customer in does not matter one bit.

So, are you making images for yourself or for a market? While I will agree you should make the best image possible, that would mean learn how to use the tools you have decided to use. You don't have to stay with them, but I think it is a mistake to always listen to what authority xxx says and stop using product y because they use product x.

It's like dr bob and Donald have both stated..it really only depends on personal preferences.

Besides, these discussions are always a great way to find out what others are doing.
