Photonic Shunkan

A follow-up to this entry: Proof that the Larger the Camera Format, the Shallower the Depth of Field We previously showed that Canon was correct to state that increasing format size reduces DOF Left: 35mm format Right: APS-C format Image: Canon Japan I thought of the following potential additional experimental setup. It is based on the fact that it makes it much easier when you compare much smaller formats with formats much larger. The problem is that I don't own or have access to a Pentax Q10 camera with the 15-45mm f/2.8 lens. The others I do have access to. I even looked to see how much a Q10 with this lens would cost on eBay...but it seems absurd to spend money on a camera just to prove that our current scientific understanding of optics is correct. Here is the setup: 1. Pentax Q10 camera ( 5.53× crop factor ) with 06 Telephoto Zoom 15-45mm f/2.8 lens (35mmF equivalent of an 83-249mm lens) set at 35mm focal length (35mmF equivalent of 193.5mm focal length) 2. A...

It is a sad fact that today some algorithm ensures the populist proliferation of gross misinformation on the internet. In an age of misinformation being spread like wildfire over the internet, readers are asked to critically evaluate the information they have been presented with: 1. Is the source of information credible? 2. Is it mechanistically plausible (in photography, on the basis of the science of optics)? 3. If objections have been raised, have these objections been adequately dealt with? Sadly, the chances are that the internet will ignore credible sources of information along with science and unquestioningly listen to Suckerberg-type algorithm driven popularisations of egregious falsehoods instead. But despite the chances that all reasoned arguments and scientifically credible evidence will be ignored, proof that the claims made in this YouTube segment are utter nonsense will be shown to the rare thinkers amongst readers: This flies in the face of what Canon st...
