Speedbooster alternative?

[Rawfa]

Is there any quality alternatives out there for the speedbooster for Canon EF lenses? The only I could find was the viltrox and one of the reviewers said it's not very good (Amazon.com : Viltrox Ef-e F/booster Speed Canon EOS Lens to Sony E Mount NEX Auto Focus Af Adapter : Camera & Photo)

I think the only alternative that I know of is to actually go FF.

Oh, come on now. Lets not threadjack and start the old apsc vs ff flames. I aready have an a7ii and now I want to replace my a6000 for an a6300 and be able to use canon glass in apsc an ff.

Not threadjacking or debating. There's a place for both formats. I was simply stating that I don't know of any highly rated speedbooster alternative other than going FF.

I would strongly second what Tre said.

I use the Speedbooster fron Zhongy Leica R to Nex, also have one eos to Nex; only affected if light on top center, can flare purple; but I use for b&w; I understand the newer version is better; and I won't pay 700$'s for Metabones...hope this helps, Takomaru

There are several alternatives. This seems to be one of the better ones:

I have to admit that I tend to agree with HiredArm though. The cost and hassle of more adapters in many ways negate the advantages of the smaller camera. Every time I consider buying a Speed Booster or similar for my m4/3 camera, I end up finding that an A7 body would do a better job in more or less every way.

I have heard good things about Lens Turbo II EF to Emount focus reducer. Although designed for Canon EF lenses, I last remember there was no electronic communication and hence would be more useful for adapting other lenses, like Nikkor, OM, and Leica R.

Sorry, I used the Word Speedbooster instead of Lens Turbo; I use the one for Leica R, but as you mention Mazor, there is no electronic communication; it works great thou for 150 bucks

Couple of hearsays in favor of something that is inferior to the Speedbooster?
