The Canon EF to RF Mount Adapter is widely regarded as an essential tool for photographers transitioning to the EOS R mirrorless system. It allows for the seamless use of older EF and EF-S lenses on RF-mount bodies with no loss in image quality or autofocus performance, often making older glass perform better than on native DSLR bodies.

The EF to RF adapter works quite well
Imo the cheap dumb adapters are the way to go, you still get focus peaking and magnification, I've also had problems with an ef adapter with a chip on an RF camera
Also, you need the ef-rf adapter for the R10 for your lenses.
Get an EF-RF adapter and a 55-250mm
The EF-RF adapter works perfectly.
Also keep in mind that the EF-RF adapter allows you to use all EF lenses and there's plenty of good bargains to be found. I'd recommend getting the one with the control ring (it's BF week).
In you opt for this direction, you may also consider including a EF to RF adapter as part of the gift, so he can use his lenses (R cameras use a different RF mount but can very effectively use EF lenses through these adapters).
you get around that by buying an ef-rf adapter with a control ring.
Then get EF-RF adapter. Works flawlessly. About $100.
Parent context: Thank you, do you know how much of an impact the adapters can have? Reply: Not for the lens you have. It is pass thru since it has no optical element in it.
