Did what I intended it to do, haven't actually used the lens much since buying this adapter but overall seems fairly solid.

Does the job well

Well maid, fits perfectly, need to see how it fares over the long term though

I'm using this with a Tamron 55-300 zoom lens on an A7RII. It's a big long lens, but connects solidly with the adapter and it feels like a single piece. Focuses fine at the macro, close and infinity ends.

Excelente adaptador, se conecta firmemente tanto a la cámara como al lente, cuenta con un swich que al ser girado habilita la posibilidad de cambiar la apertura del diafragma de manera manual, el adaptador no tinen ningun elemento dentro por lo que la imagen pasa con claridad directo del lente a sensor. PRO: - Usal lentes viejos en camaras nuevas sin espejo. - Permite el control completo del lente conectado a la camara. - Hace justo lo que se anuncia. CON - No tiene soporte para tripie

The screw that holds in the locking clip and spring in place broke off 4 days after the return window closed. I appreciate the refund when I contacted support as I didn't have faith that a replacement would do the job. A disappointing purchase but well handled by Amazon.

I'm 💯 Satisfied

This adapter works perfectly for old Canon FD lenses. The aperture ring has worked on all the lenses I’ve tried (extension tubes also worked). Some lenses don’t require the adapter’s “lock” ring to be turned, like the 50mm f/1.4 SSC with the breech lock, but the ones that do need to be locked work as expected. Of course, make sure to turn the lock ring to “open” before changing lenses. This adapter does NOT come with any front or rear caps. (If you plan on leaving this adapter attached to one lens, you’ll want that rear lens cap to keep it sealed, and clearly you can’t use your FD rear cap unless you detach the adapter between uses.) It’s made of what seems to be good quality metal, not very heavy. It attaches to my A7 IV solidly without any slack. Lenses also do not have any slack. And for extra clarity, this adapter has no need for glass because the flange distance on the E mount is shorter than the FD mount. Also, there are no electronics here so don’t expect that “A” mode on your FD aperture ring to work. Usually when you use stuff like this or switch to manual focus, Sony bodies will automatically turn on focus peaking. You’ll definitely want that feature enabled so you can focus accurately. So far I’ve had no problems with focus at all. I was originally looking at a more expensive FD to E adapter, but honestly this one has worked perfectly and intuitively so far.
