Highest-end OM-D camera based on the E-M1 Mark II, introduced in 2018. Built-in vertical grip. Very ergonomic handling and button layout. Very large EVF magnification. Almost twice as heavy as the E-M1 II. Long battery life. The main difference between them is the ergonomics and the customizability.
4.5 + 4.5: H: 91.3 L: 65.1 W: 52.4 This battery contained two independent 4.5 V batteries, and had a four-pin connector. 9 V with a center tap was available by wiring in series. There were two ⌀3.2 mm negative pins spaced 9.5 mm apart and two ⌀4.0 mm positive pins spaced 14.3 mm apart. Negative and positive pins were spaced 18.1 mm apart.

The term camera is also used, for devices producing images or image sequences from measurements of the physical world, or when the image formation cannot be described as photographic: Acoustic camera which makes sound visible in three dimensions
The name of the system stems from the size of the image sensor used in the cameras, which is commonly referred to as a 4/3" type or 4/3 type sensor. The common inch-based sizing system is derived from vacuum image-sensing video camera tubes, which are now obsolete. The imaging area of a Four Thirds sensor is equal to that of a video camera tube ...
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras.
Looking at the Wheatstone bridge circuit shown, the voltage drop on the lower left hand side is V_rtd + V_lead, and on the lower righthand side is V_R3 + V_lead, therefore the bridge voltage (V_b) is the difference, V_rtd − V_R3. The voltage drop due to the lead resistance has been cancelled out. This always applies if R1=R2, and R1, R2 ...
A feature of the SX-70 film packs was a built-in battery to power the camera motors and exposure control, ensuring that a charged battery would always be available as long as film was in the camera. The "Polapulse" battery was configured as a 6 volt thin flat battery, and used zinc chloride chemistry to provide for the high pulse demand of the ...
