EinsteinsGhost: Forgive me for being so bold, but may I ask a question? Do you ever use the histogram function of your camera? I know it has one. Several of the images you've posted recently (and not so recently) have had extreme clipping in the highlights, especially in the red channel. This is not good at all, as once that information is gone it's gone forever.
I'm not sure if your camera's histogram has a color channel view, but if it does it can come in very, very handy, because usually one color channel will clip before the image as a whole does, and for various reasons it's almost always the red channel that goes first. If you already know this and the photographs are the way they are for a reason, then please accept my apologies.
I find the 3 color channel histograms so indespensible when shootiong reds. reds blow out so easy leaving flowers looking like tomato skins.
the one channel histograms are not so good as it is weighted to blue and green and usually will not indicate the reds are gone.

Thank you for the critique. Indeed, you don't want reds to blow out but in this particular case, red and orange dominate and the idea was to catch the glow rather than underexpose it. I shot this in rain (you may see a few rain drops captured mid air in some of these recent images).
Much of this loss of detail is actually in the area where there is less details (blur) as I was also testing speedbooster on a fast lens (55/1.4 lens with the speedbooster has an effective f/1 for aperture). Also, the histogram (luminosity vs RGB) can make a difference. In case of histograms in general the overall scene also plays a signifcant role.

Lunar Delta, even though the question is directed to EinsteinsGhost, I'd like to chime in. As far as I know, live histograms in consumer cameras rely on information extracted from an 8-bit sRGB or AdobeRGB JPG file. Checking histogram is useful especially if you shoot JPG only. Histograms don't reveal the full color/luminance gamut to those who shoot in RAW. The red channel clipping you've pointed out in the tulip shot, may be a result of converting a RAW file from ProPhoto RGB color space to sRGB without color proofing the end result. The information/detail isn't lost for EinsteinsGhost if he shot it in RAW, it's us who don't see it due to a limiting factor of sRGB color space.
And it's a nice shot! SB does miracles to some lenses.
Here's my contribution to the flower thread: Passion Flower
Yes, red channel is slightly blown after conversion to JPG.
