How to use with modern cameras?

Lenses with mounting thread M42 (M42 X 1 / 45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this it is enough to choose the right adapter (adapter). You do not need to carry out any additional steps to modify the lens.

The cheapest adapters can be found aliexpress.com... There are adapters (adapters) with a chip that provide more convenience during shooting, usually chips are used to confirm focus and / or metering exposure, and form the correct EXIF. The chip does not affect the image quality in any way.

For some SLR cameras (for example, Nikon F) it is necessary to use adapters with a corrective lens, which allows correct focusing at all focusing distances. For any mirrorless camera, such a lens is not needed, and the adapter is a simple decorated hollow metal tube with an appropriate mount.
