I think this is the crux of what I'm trying to say. Anamorphic adapters ARE horizontal-only speed boosters. Let's compare my 0.71x speed booster (SB) with my Sirui 1.25x anamorphic adapter (AA). Both widen the FOV: If I take a 50mm lens and mount it with my SB, I will have the same Horizontal-FOV as mounting a (50*0.71=35.5) 35.5mm lens. This is why they're called "focal reducers" because they reduce the effective focal length of the lens. If I take a 50mm lens and mount it with my 1.25x AA, I will have the same Horizontal-FOV as mounting a (50/1.25=40) 40mm lens Both cause more light to hit the sensor: If I add the SB to a lens then all the light that would have hit the sensor still hits the sensor (but is concentrated on a smaller part of the sensor) and the parts of the sensor that no longer get that light are illuminated by extra light from outside the original FOV, so there is more light in general hitting the sensor, therefore it's brighter. This is why it's called a "speed booster" because it "boosts" the "speed" (aperture) of the lens. Same for the AA adapter Where they differ is compatibility: My speed booster has very limited compatibility as it is a M42 mount to MFT mount adapter, so it only works on MFT cameras and only lets you mount M42 lenses (or lenses that you adapt to M42, but that's not that many lenses) My Sirui adapter can be mounted to ANY lens, but will potentially not make a quality image for lenses that are too wide / too tele, too fast, if the sensor is too large, if the front element in the lens is too large (although the Sirui adapter is pretty big), and potentially just if the internal lens optics don't seem to work well for some optical-design reason The other advantage of anamorphic adapters is they can be combined with speed boosters: I can mount a 50mm F1.4 M42 lens on my MFT camera with a dumb adapter (just a spacer essentially) and get a FF equivalent of mounting a 100mm F2.8 lens to a FF camera I can mount the same lens on my MFT camera with my SB and get a FF equivalent of mounting a 71mm F2.0 lens to a FF camera I can mount the same lens on my MFT camera with my AA and get a FF equivalent of mounting a 80mm F2.24 lens to a FF camera (but the vertical FOV will be the same as the 100mm lens) I can mount the same lens on my MFT camera with both SB and AA and get a FF equivalent of mounting a 57mm F1.6 lens to a FF camera (but the vertical FOV will be the same as the 71mm lens) So you can mix and match them, and if you use both then the effects compound. In fact, you'll notice that the 50mm lens is only 57mm on MFT, so the crop-factor of MFT is converted to be almost the same as FF. If instead of my 0.71x speed booster and 1.25x adapter, we use the Metabones 0.64x speed booster and a 1.33x anamorphic adapter, that 50mm lens now has the same horizontal FOV as a 48mm lens, so we're actually WIDER than FF. What this means: On MFT you can use MFT lenses and get the FOV / DOF they get on MFT On MFT you can use S35 lenses and get the FOV / DOF they get on S35 (*) On MFT you can use FF lenses and get the FOV / DOF they get on FF (**) On S35 you can use S35 lenses and get the FOV / DOF they get on S35 On S35 you can use FF lenses and get the FOV / DOF they get on FF (*) On S35 you can use MF lenses and get the FOV / DOF they get on MF (**) On FF you can use FF lenses and get the FOV / DOF they get on FF On FF you can use MF+ lenses and get the FOV / DOF they get on MF (***) The items with (*) can be done with speed boosters now, but can also be done with adapters so anamorphic adapters give you more options. The items with (**) were mostly beyond reach with speed boosters, but if you combine speed boosters with anamorphic adapters you can get there and beyond, so this gives you abilities you couldn't do prior. The item with (***) could be done with a speed booster there aren't a lot of speed boosters made for FF mirrorless mounts, so availability of these is patchy, and the ones that are available might have trouble with wide lenses. One example that stands out to me is that you can take an MFT camera, add a speed booster, and use all the S35 EF glass as it was designed (this is very common - the GH5 plus Metabones SB plus Sigma 18-35 was practically a meme) but if you add an AA to that setup it means you can use every EF full-frame lens as it was designed as well. -
I shoot also mostly with available light, and when the sun has set in the light of dim headlamps. So being able to push and pull shadows and highlights is extremely important. In that regard GH7 is no slouch, but it is not quite the same than Z6iii, ZR nor even S5ii was either. If you have a good HDR capable display (and I don’t mean your tiny phones, laptop or medium sized displays, but a 65” or bigger OLED with infinite contrast, or a JVC projector with good contrast and inky blacks) one must be a wooden eye to not notice the difference between SDR and HDR masters. At least with my grading skills the 6 stops of DR in SDR look always worse than what I can get from HDR. -

Probably. I just found it really overbearing. I personally don't bother with diffusion filters at all. The short, lacking detail reason is that I'll just use a vintage lens if I want a vintage look. And yes, your observations align with mine about using diffusion filters. On low-budget sets, they also add headaches on controlled shots as the DP is now complaining that the lights are interacting with their diffusion filter in a bad way, causing time loss due to coddling the darn thing. -

I think you're assigning more capability for logic to my government than they deserve.
