Shutter lag is much more of a problem with digital cameras.Here, the delay results from the charging of the charge-coupled device (CCD) image sensor and relatively slow transmission of its capture data to the circuitry of the camera for processing and storage.
Analog wireless is found in three frequencies: 900 MHz, 2.4 GHz, and 5.8 GHz. Currently, the majority of wireless security cameras operate on the 2.4 GHz frequency. Most household routers, cordless phones, video game controllers, and microwaves operate on the 2.4 GHz frequency and may cause interference with a wireless security camera.
The Zorki 4, 1956, is a Zorki 3S with self timer added.The Zorki 4K is identical but used an advance lever instead of the old-style wind knob.

Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...
The Zorki 4 was possibly the most popular of all Zorki cameras, with 1,715,677 cameras made by the KMZ factory in Krasnogorsk, Russia.

An additional lightmeter may be added by the cold shoe.
Lenses produced for 35 mm film cameras may mount well on the digital bodies, but the larger image circle of the 35 mm system lens allows unwanted light into the camera body, and the smaller size of the image sensor compared to 35 mm film format results in cropping of the image. This latter effect is known as field-of-view crop.
