Strictly speaking, "Boost ISO" means nearly as much as "HD" written on the objective. It is a buzzword without formal definition and may be misused as such. Consequently, it is not possible to give precise answer about it's usage. Neither 2 nor 1 is completely correct. the pixel does not send the number of photons (it is read as a voltage, not an integer ...

You're getting a little confused. Un-boosted ISO Or what you're calling "native range." There's a native ISO setting, which is what the sensor uses without any amplification, and you can consider this the "base" ISO setting of the camera. All of the unboosted other ISO settings are achieved by amplifying the gain on this native signal. Boosted ISO ...

The answer is 2, hardware amplification only for native ISO, hardware with additional software amplifications/reduction for extended ISO. Extended ISO is like taking a RAW image and then changing ISO in Lightroom, only it's done is camera. Extended ISO also only works in jpeg, not raw for obvious reasons. Meaning physical exposure is done in native ISO and ...

Native ISO is the camera ISO sensitivity that requires the least amplification to be read by the A/D. It's a precise attribute of the design of the camera, does not have to match the standard ISO values (and often it doesn't) and doesn't imply the absence of any amplification -the A/D converter needs a readable signal, after all. The camera knows internally ...

I would start by using a different memory card.

What sort of features does this typically include? For Canon cameras (or the 6D at least), the camera can connect to an existing network or create a network of its own. You can then transfer photos from the camera or use Canon's software to control the camera. Does this mean if I input my username and password into the camera, it will automatically ...

What sort of features does this typically include? Typically, any camera with wi-fi capability can basically be a wifi hotspot, so you can use an ad hoc network between the camera and a smart phone or tablet to transfer photos from the camera to the device, use the device's GPS positioning to geotag photos, or to establish a remote control path to the ...

Viewfinder "vignetting"/"tunnel view" My vote is that the type of screen on the back of the camera is the culprit causing the darker corners of the view. The size of the screen is large and the angle of view of the corners is more oblique than through the centre, which appears brightest. The corners are darker due to increased corner illumination "falloff" ...

The Sony A6000 is $500. Show me a full frame for that price, and I will accept your argument that even the body, let alone the lenses, are the same for a full frame dSLR as they are for an APS-C compact mirrorless. The only full frame camera I know of that matches even the A6300 or Fuji X-T10 in price is the A7(which is showing its age!), which is also ...

People get very hung up on "quality". I think Internet review sites are partly to blame, because they get traffic by analyzing the minutia of this vs. that measurement. Keep in mind, though, that the baseline for quality is very, very high, and every modern camera with a 1" sensor or large is capable of stellar results. We're not talking "C" vs "A", here — ...

Looks like a common case of lens vignetting. Here is a link to help you do some further research on understanding what causes this issue. https://support.nikonusa.com/app/answers/detail/a_id/14467/~/what-is-vignetting%3F

If the camera you have is a Nikon then a search for "c mount to nikon f" would turn up something that ought to let you attach the camera to the microscope. If not Nikon then substitute manufacturer & lens mount type as necessary...

The adapter you listed is made for doing the opposite of what you wish to do: It is made for using C-mount cameras with DSLR lenses. There are a couple of issue with doing what you want that make it problematic: The C-mount registration distance (a/k/a flange focal distance a/k/a distance from the film/sensor to the lens mounting flange) is 17.526mm. The ...

Whether this is where you found it or not, the definition you give for "Unity Gain ISO" comes from the Clarkvision web site's section on digital sensor performance. As an updated version of that page explains, it's a silly concept. To quote: The fundamental reason Unity Gain is not relevant is because the sensor in a digital camera is an analog system, ...

Unity gain is such ISO number at which camera outputs pixel values roughly equal to numbers of electrons in cells. Native ISO is such ISO value at which the maximum number of electrons in cell is matched to saturation point. It is almost always division instead of multiplication for sensors with big enough electron capacity per cell. Native ISO is as unique ...
