Hi everyone,

Anyone have a hands on with the above spped booster adapter that gives your M series cam with a full frame viewing and a 1 stop aperture advantage.

Sold in amazon and viltrox homepage for USD 156.

Thanks.

Hi I have it. Work like a charm and I have another extra(cos people were saying the Amazon seller was a fake and so I shopped around for another.

If you are keen to transact I can let go at $250.

Can I ask if iyou have tried it with any APS-C (EF-S) mount lenses? Any vignetting?

According to spec, only FF EF lenses. EF-S, EF-M won't work.

Bought my Viltrox sppedbooster.

Great for STM lenses.like my 40mm pancake. However, not so great on old micro motor lenses.

Anyone tried using adapted FF manual lenses like M42 or nikkors on it?

It will only mount EF lenses, not EF-s, so cropp 3rd party lenses can be mounted like sigma 18-35mm f1.8

The focusing spped is slightly slower. but fine with me.
