Different camera makers' dedicated flash systems are, in fact, incompatible in terms of both the proprietary contact layout and the communication protocol. That said, many current wireless radio triggers for professional studio strobe systems remain a relevant real-world application of the basic ISO 518 hot-shoe design. Their use with Sony and Minolta DSLRs requires either the Minolta FS-1100 adapter, now discontinued, or the Sony FA-HS1AM adapter. Named

At first sight it resembles a standard ISO 518 hotshoe with just the middle contact and chassis and without any vendor-specific extra contacts, but additional contacts are hidden under the front of the hotshoe. The new hotshoe is mechanically incompatible with the iISO hotshoe, but electrically backwards compatible. The first cameras to use the new hotshoe are the

To soften the impact, Minolta had made available a FS-1100 (8825-670) adapter allowing to mount the old flashes and controllers on new bodies, and a FS-1200 (8825-680) to do the reverse. A custom-modified variant of the FS-1100 also featuring a

The use of the button-operated latch, besides facilitating a quick, one-handed flash attachment and detachment, also eliminates the possibility of the flash gradually working itself loose and shifting in the shoe, which on camera systems using the ISO 518 hot-shoe can lead to certain contacts

During its 1988 introduction, the new
Minolta iISO flash shoe presented an inconvenience to users with significant investment in the old, ISO 518 based Minolta flashes and accessories. The fact that Minolta chose to offset the new flash shoe introduction by three years from the 1985
