Fuji X-E2 + Metabones Speed Booster compared to the Sony A7r, 'faux full-frame' or a genuine alternative? Soundimageplus accessory of the year.


I've never had the opportunity before to see just how much of a 'full-frame' view the Metabones speed booster for my Fuji X cameras lets me have. However with the arrival of the Sony A7r and it's ability to accept the same Nikon lenses I use on my Fuji's, I have the opportunity to check this out and share what the same lens produces on each camera, with a Metabones Speed Booster on the X-E2. For this I used my three Nikon G lenses, tripod mounted. I shot all three comparisons wide open to see what the depth of field looked like and just how much the speed booster crops from the frame. Below is what I got. Jpgs. shot at ISO 100 on both cameras.




As you can see, the Fuji with the Speed Booster does crop in a little and there is slightly more vignetting. From the 0.71x crop I get 'equivalents' of 30mm, 53mm and 90mm approximately, but as you can see it's pretty similar framing. The background bokeh looks very close also. 

So is this 'faux full-frame' or a genuine alternative? Well I think it is a genuine alternative, if you are happy to use manually focused lenses that is. And of course this option is available for other APS-C sensor mirrorless cameras, such as Sony NEX. The m4/3 speed booster turns lenses into APS-C approximations so that's something different. But I must say I really do admire the whole Speed Booster idea. There is of course the extra 1 stop of light that you get as well, so all in all it's a pretty great piece of kit.

As I indicated in a previous post, I invented the catergory Soundimageplus Accessory of the Year just for the Speed Booster and it is with great pleasure that I announce that today. (Polite round of applause please!!) So again congratulations to all involved in putting the Speed Boosters together. It's not often something so small makes such a difference, but in this case it really adds something of value and of course makes using legacy lenses on mirrorless cameras less of a 'geeky fetish' and more of a serious faster and higher quality alternative to many native brand lenses. The Nikon 50mm I used above becomes in effect a 53mm f/1 lens and I dread to think how much one of those would cost if Fuji ever made one, even manual focus only. So using the speed booster does actually improve and add to the options for my Fuji cameras. Factor in the terrific high ISO performance and you have a real low-light monster camera that lets you shoot in virtually any light, or even approaching no light at all. So a real innovation and one that should be recognised as such.
