digital camera sensor size chart.
inspired by rising buzz about micro four thirds, which is just what i was missing so long. it was made first for myself, as long, as other charts, just to make an system in all absorbed information. maybe someone of you will find it useful.

During summer aircraft take off on an almost daily basis. Concordia is a hubbub of activity as researchers from disciplines as diverse as astronomy, seismology, human physiology and glaciology descend to work in this unique location.
For the rest of the year, around 14 crewmembers remain to keep the station running during the cold, dark winter months.
ESA sponsors a research medical doctor in Concordia to study the effects of living in isolation. The extreme cold, sensory deprivation and remoteness make living in Concordia similar to living on another planet.

I wanted to know the usable dynamic range of my dSLRs. Here are the results of my Nikon D70 test. The results for Nikon D50 were pretty much identical. See also discussion in the strobist group.
Executive summary
Never shoot with higher ISO than 200. It is better to take underexposed shots with ISO200 than properly exposed shots at ISO800. The higher ISO will just reduce the dynamic range, whereas the same shadow details can be recovered from the underexposed low ISO shot with more highlight latitude.
The experiment
Here is how I did the test. I placed a camera on tripod and a piece of white tissue paper on the table. I set the exposure of the camera at 1/160 s and f/16, and illuminated the paper with a Nikon SB-800 flash bounced from the ceiling. I altered the light output of the flash to get darker and brighter exposures. The exposure in camera was kept constant, except for the four brightest frames, where I had to open up the aperture to f/2.8 and adjust the flash power accordingly to get every frame one stop brighter than the previous.
After having transferred the RAW images on a computer, I adjusted the brightness of each photo in the dcraw RAW converter so that the brightness of the piece of paper should be same for each exposure. That means the frame marked -1 EV was brightened one stop, -5 EV was brightened five stops and +3 EV was darkened three stops etc. I used the highlight recovery mode of the RAW converter to get the best possible amount of highlight detail from the brightest photos.
The patches shown are 100% crops from the images where the brightness has been adjusted.
Results for ISO200
At ISO200 there is about six stops of dynamic range with very little visible noise. The best dynamic range extends three stops up to +3 EV and three stops down to -3 EV from normal exposure.
Subjects more than three stops brighter than normal exposure will lose details because of clipping (at +4 EV or more). Subjects more than three stops darker than normal exposure will have visible noise. At -4 EV the noise is visible but not very bad. At -5 EV the details of the subject are barely visible because of noise, and at -6 EV the details are almost completely lost.
Results for ISO800
I repeated the same experiment also at ISO800. I was disappointed with the high ISO results.
The shadow details of the ISO800 photos were nearly identical to the shadow details of the ISO200 photos with the same exposure and same amount of light. The only effect of using a higher ISO was that the dynamic range was reduced by two stops.
That means the ISO800 mode is useless. It is better to shoot at ISO200 and underexpose the shots by two stops than switch to ISO800, expose normally and lose two stops of highlight details.

APS-C sensor, X-Trans CMOS III.
Flagship model of Fuji X series. My husband wrote the review in Japanese, I took the photos of the camera, in March.

This is a crop of the bottom right hand corner of an image taken with a pinhole lens. It shows numerous drops of liquid (probably oil) on the sensor filter.
(I didn't turn the light off-- I just cupped my hand over it.)
A simple, quick, and very cheap circuit to turn on an LED when it gets dark. Read more about this project here.
This is a 5 megapixel image sensor from my old HTC Aria Smart Phone.
This is a little bigger than 1:1 macro since the Nikkor 40mm 2.8G DX can be manually focused a little past 1:1. I used both of my SB-700's for this. They were set to 1/50th power.
To operate safely and accurately, a CNC machine must "know" where all of its components are at any given time. Proximity sensors, such as these, located throughout the machine, provide much of this location information. Haas uses a common sensor across the product line to reduce costs and simplify service.
Muzzle flash and pink nails. Shayla Miller, Product Manager Soldier Maneuver Sensors cost analyst, fires the M4A1 Carbine equipped with the latest in Rapid Target Acquisition technology that wirelessly connects the weapon’s thermal sensor and reticle with the Enhanced Night Vision Goggle III. The thermal sensor, called the Family of Weapon Sights-Individual, mounts in front of the M68 Close Combat Optic. Miller is one of several members of PM SMS who received hands-on familiarization with one of the latest capabilities being developed for Soldiers. The familiarization training was conducted at the Communications-Electronics Research, Development and Engineering Center’s “Night Vision Tunnel” at Fort Belvoir, Virginia. PM SMS is part of Project Manager Soldier Sensors an Lasers within Program Executive Office Soldier.
This photo is taken with a 32 year old lens (!). The Nikon 135mm f/2.8 from 1980. It's the predecessor to the modern portrait lens, 135mm f/2.0 DC.
This lens produces very unique and lovely looking images at 2.8, though it is mildly soft at this aperture. It goes all the way to f/32. Something I've never seen in such an old lens. Those others I've got has maximum of f/22 and f/16. Has not had the chance yet to shoot at max aperture.

Camera is currently being fixed at Nikon's, I hope this will be its last trip.

Cheyenne linemen install sensors on a lattice steel structure on the Ault-to-Hayden 345-kilovolt line. The sensor will measure conductor or static temperature, current, movement along every axis and the speed of the motion. Using this data, maintenance crews and engineers are investigating if spacer dampers on this line need to be replaced and if a different configuration may better prevent the conductors from hitting each other.

I was trying to clean my sensors on a Nikon D600 and D7000. The Bblow bulb i used had a plastic tip that shot out of the end and i was worried i may have cracked the mirror!
Principal investigator Jacques Loui, left, and a firmware developer are part of a team redesigning high-performance radar as a flexible, multipurpose sensor.
Researchers are working to replace legacy analog radars commonly used by the military with a new, digital, software-defined system called Multi-Mission Radio Frequency Architecture. The overhauled design promises U.S. warfighters unprecedented flexibility and performance during intelligence, surveillance and reconnaissance operations, even against sophisticated adversaries.

I came across this interesting comparison on the internet today. I'm toying with the idea of getting another compact camera and at present it's a toss up between the Sony 100 iii (still available though newer models have been released) and the not yet released Panasonic TZ90.
The Sony has a 1" sensor whilst the Panasonic has a 1/2.3" sensor; this is somewhat outweighed by the Panasonic's longer optical zoom range and more flexible screen.
Given the generally poor performance of my Ricoh GR4 (which has a 1/1.7'' sensor) compared with my iPhone 6 (1/3'' sensor) perhaps I don't need another compact camera anyway.
The cam unit provides focused vision. Peripheral vision is provided by sensors behind the translucent red plating on the front.
Agfa Silette LK Sensor, introduced 1970, perhaps one of the last Silettes and an early Agfa with the red shutter release button. The body is based on the Agfa Optima 200 from 1968.
It is a low-budget camera, the lens barrel and the housing are made of plastic, though the top and the bottom look like metal. This camera hasn't a rewind crank, the rewinding is done by the advance lever, when the button "R" is tripped before, so the inner mechanism is complex.
The lens is a Color-Agnar 2.8/45 mm with three elements, the shutter is a Parator with 1/30 to 1/300 s and B. The Selenium exposure meter is coupled and the match needle is displayed in the viewfinder and on top, the ASA range is from 25 to 400 ASA. All settings has to be done manually, like on all Silettes, I think. The LK has a thread for a cable release on the backside and a hot shoe. There is no self-timer, no focussing aid and the frame counter has to be reset manually.
(If you want to remove the top plate: there is a third screw hidden in the hot shoe. The cover in the hot shoe has the most diabolic clip mechanism I've ever experienced.)
