EF refers to the condition or grading of the coin, it means "Extremely Fine".
An "Extremely Fine" coin should show some slight signs of wear that are barely noticeable to the naked, unassisted eye.
EF=0 means when the net force on something is 0 (zero).
i have a ef&ef green lamp #502. how much is it worth
No, EF-M lenses are not compatible with EF mounts. EF-M lenses are specifically designed for Canon's mirrorless cameras, while EF lenses are designed for Canon's DSLR cameras with EF mounts.
No, an EF lens will not fit an EF-S camera body.
EF (or XF) stands for Extra Fine (sometimes also called Extremely Fine), one of the higher grades for a circulated coin. An EF coin will have very slight wear on the high points of the design but no other evidence.
Jai ho! ef ef ef
Gee-ef-ef.
I assume you mean ejection fraction and yes it is 0-100% however in many years of testing for EF i have never seen anyone with an EF over 80% and an EF of 100% might be techincally though not necessarily theoretically impossible.
My EE EF lamp is marked Chicago if that is any help.yes
The best EF-M lenses compatible with the EF mount are the Canon EF-M 22mm f/2 STM, Canon EF-M 32mm f/1.4 STM, and Canon EF-M 11-22mm f/4-5.6 IS STM.
The main difference between Canon EF and EF-S lenses is their compatibility with different camera bodies. EF lenses are compatible with both full-frame and APS-C sensor cameras, while EF-S lenses are specifically designed for APS-C sensor cameras. EF-S lenses are generally smaller and lighter than EF lenses, but EF lenses offer a wider range of focal lengths.
EF Concepción was created in 1976.
