Overview of Micro Four Thirds adapters for Canon Lenses 

It's not as good as native lenses ever, it's a compromise when you want to use older lens, or not spend money on new lens. Often enough, the results are very acceptable. If you're going after a specific look these can certainly achieve that. But if you're going after absolute quality, go native.

Unlikely because the image projected wouldn't cover the whole sensor. Unless the adapter includes some "magnifying" correction lens

Yes

NO. Canon EF lenses only, per Metabones. EF-S lenses like the 18-55, designed for Canon APS-C DSLRs, will not work.

Vertix, I'm sorry. I didn't read your question carefully enough before first answering, and I can't delete or edit my answer now. You were not asking about the Metabones Speed Booster; you were asking about a different adapter. I don't know the answer to that question, but like you, I suspect the image might not fit the sensor correctly, because EF-S lenses are designed to hit an APS-C sensor, not a full-frame sensor. You'd best explore that on the website of the company making the adapter you're asking about. They may make a different manual adapter for Canon EF-S lenses.

Sounder Davis I just read that the Viltrox M1 is made for Canon efs lens for micro 4/3.

The Best one is the Metabones, but it's expensive. The simple ones are not that good. I'd go with some brand named ones that don't have lenses.

@@SLRTom Great, thanks Tom!

Yes of course, they share the same mount.

Sadly, no.

@@ilusoriob that I tried with om50mm 1.4 the light gathering was the same as with Lumix 25mm f1.4 depth of field became 2.8, so it does retain the same light on both lenses without a speed booster, try it out ta

Wow get a fucking grip dude....go panhandle or just go old skool and give hand jobs if you need money 4 gear that bad

Schwellenzaehler45 there isn’t a camera body under $700 on earth that I’d want to use, with the exception of maybe Canon 1D Mark I!

@@spi-fi_media , okay .... it seems you are a poser ; -)

Schwellenzaehler45 the 90’s called, they wanted you to know they want their burns back! Heheh
