kye Posted February 29 Share Posted February 29 The only reason you might not be able to is if the optics in the speed booster protrude too much and will interfere with the lenses you're planning on using. I have a vague recollection this was the case for some of those BM-specific speed boosters, but couldn't tell you which ones. Quote Link to comment Share on other sites More sharing options...
Tim Sewell Posted February 29 Share Posted February 29 I have an EF to E speedbooster and an EF to E smart adapter. In turn, I have M42 to EF adapters on all my M42 lenses and OM to EF adapters on all my Zuiko lenses and they generally work fine on both. The only issues you might find would generally be with infinity focus due to slight inaccuracies in adapter depth (which can quite often be remedied by shimming with tin-foil!). A lot of people report issues with Minolta MD/MC adapters and Canon FD adapters, but specialist ones are available. At the end of the day, it's a case of 'order the kit from somewhere with a good returns policy and see if it works', but the chances are that it will!

I did some digging and I found this article using xl speedboster EF to m43 with adapter Here’s a 2021 Update: You don’t have to do this for modern speedboosters like ULTRA and XL, mine fitted perfectly on the viltrox EF to MFT with cheap ebay CY adapter (Except I had to turn the glass of speedbooster to fix infinity focus) but that’s a seperate issue. On the Metabones some lenses might scratch the velvet side only slightly so maybe if you don’t want that you can trim the pins just slightly but not the whole way using a professional or at home with metal cutting plier. I think author uses old gen speedboosters since it’s 2016 but I also read this post while my lens is arriving by post and I panicked a lot and this post made me panic even more having to do this to a rare lens.
