Apart from the obvious difference in aperture, can anyone speak to the differences (if any) between the f/3.8 and f/4.5 Triotars? Does anyone think they can see any discernible differences in how they render images? The difference in speed seems slight -- why did F+H offer both lenses? Is there any advantage to one over the other?
