CanonMulti-Function Shoe Adapter AD-E1

It works as well as you would expect, but it is awful that I need to buy this to use speedlites on my Canon R50.

Muy buen producto, súper protegido, muy contento con el producto y la entrega

works good so far. I haven't use it much yet.

Recently got the Canon R50 camera. Have the EF style camera from before, and wanted to get the smaller form factor for travel due to the smaller size and less weight.With this adapter, I am able to use my old Canon flash with the R50 camera, which is important as there are not too many flash options available at this time for the R50. My E-TTL2 flash works perfectly, and it was a smaller investment than buying a new Canon flash.

Makes the other flashes functional on the Canon R series that changed to proprietary hotshoe.

With the update of the EOS R5 to the Mark II release, a new (more advanced) hot shoe now thrones on top of the camera. The manual of mentioned camera specifically says: To "attach [the] GP-E2 to the camera's hot shoe [...] requires a Multi-Function Shoe Adapter AD-E1 (sold separately)." There is no reason given, but the same remark applies to the Speedlite EL-1 as well as the (older) 580EX.Upon receipt, I did the unthinkable. I simply attached the (now discontinued) GPS receiver GP-E2 directly to the EOS R5 Mark II. Looks like it should work, and—to my surprise—it sure does. In fact, it does not work any differently than with the adapter. So why do I need this pricey piece to begin with? The $42 are even slightly above MSRP ($39) because it's also out of stock a lot. Hence, it's not a money grab for Canon if they don't make enough. But there may be some (good) reasons to use the adapter, well about two.1. Weather seal: The new hot shoe has a slightly unique shape and the weather seal of older devices doesn't match that perfectly and may allow water ingress. That's certainly a good reason for the intrepid photographer facing the elements, but my usage is a lot more tame and this is mostly a "nice to have".2. Protection: As the recessed finer contacts of the new hot shoe appear reasonably protected, Canon apparently still believes that it's possible to ram a conventional hot shoe in enough to damage the contacts, especially when locking. I am not brazen enough to jeopardize my $4k body just to prove this concern right or wrong, and therefore, this might be the single reason for the adapter. (If you're careful, however, this is still somewhat optional.)Added functionality from the additional contacts in the new design doesn't matter as it doesn't transfer to the old devices, anyway. Namely, the new Speedlite EL-5 takes advantage of the more capable interface to communicate better with the camera while also sitting where Canon intended (regarding the light output relative to the image area). An older Speedlite 580EXII, for instance, doesn't have this interface and can "understand" only traditional controls. Here it simply allows to use older equipment, maybe until one can upgrade. The new interface allows to tap into the camera's processing power where the traditional interface required that to live in the peripherals (i.e., flash autofocus the 580EX handles itself, whereas the EL-5 relies on the camera.)In a way, that's the situation with the GPS receiver GP-E2, but apparently Canon relies now on getting this information from a smartphone and discontinued those receivers with no new version on the horizon. Ironically, the camera itself already lost the ability to record the shooting direction in the R5 and the Mark II is not different. This was THE major advantage for me of using the GP-E2 with the 5D Mark III. Without that, the results are nearly identical to using a smartphone while keeping the hot shoe available.So, why did I just buy this? Well, mostly because Canon implies it to be mandatory when using older equipment (or third party). For now, the two reasons above serve as my justification for the expense.

Works well. It’s just frustrating that Canon requires you to purchase this is you want to use a flash on an R camera. There is no reason why they couldn’t have designed the shoe to accommodate a flash without this extra piece of equipment.

This adapter works well.My only issue is, why do I need to buy a hotshoe adapter for my camera's hotshoe??Makes no sense. They should make the camera hotshoe universal to all Canon flashes.
