Hey, no trolling ever intended. I like the Rollei and have always been curious as to the advantages of the SWC as I've never had the good fortune to meet one, or shoot with the Biogon. And the original photo is wonderful in its own right. I do shoot my SL66 handheld a good deal of the time, for whatever it is worth, though it is admittedly a load that is well served by a good tripod and head.
