First Impressions: Metabones Speed Booster: Digital Photography Review

"There's a lot to be excited about with a product that so transforms lens behavior and addresses such a long-standing issue for photographers who long for the wide-angle and light-gathering performance of their older full frame lenses on their newer APS-C body. Image quality is very impressive, with results that compare exceptionally well against a full frame sensor. You do pay a small price in terms of corner softness and CA.

The biggest remaining challenge, however, with the Canon EF to Sony NEX mount is AF speed, a direct consequence of pairing a PDAF-optimized lens on a CDAF sensor. And to their credit, Metabones makes it very clear that AF performance is going to lag far behind what you'd get by using the Sony NEX's conventional AF system.

This does effectively make the Speed Booster an even more niche product, as it's best suited for manual-focus shooters. We'd be keen to see a camera manufacturer license this now-proven technology and offer this optical quality and near-full-frame performance mated with an effective AF system. But for now, we tip our hats to Metabones for releasing a product that accomplishes what many had thought nearly impossible."

I pocieszające informacje

From an FAQ section the MB product site:
“Will there be Speed Boosters™ for Canon FD, Minolta MD and Sony Alpha lenses?

We will be looking into Canon FD, Minolta MD and Sony Alpha in the future. We do not have an estimated date yet. Disclaimer: this shall not be construed as a commitment to ship – we are not done prototyping any of these yet but we will conduct testing to decide if these lenses are free of interference issues with the optics of the Speed Boosters™ before we will be able to turn them into actual products.”

Z sampli wniosek nasuwa się jeden: poprawy jakości obrazka w stosunku do matrycy FF nie ma.
Trudno się było zresztą tego spodziewać.
MZ wartość tego typu konwertera przesadzona przynajmniej czterokrotnie.

Ale jest jaśniej i... szerzej???

Dla aparatów z mniejszą minimalną odległością od bagnetu - owszem.

"I think it was pretty obvious that I came armed for battle, ready to slam this product as some marketing overhype. I was wrong less correct than I might have been. The Speed Booster does what they claimed it would do, much to my shock and surprise.

(...) And this is going to be a very useful tool. "



Metabones Speed Booster adapter – full review | EOSHD.com


"Pros

1 stop increase in low light performance
Full frame look – wider field of view, shallower DOF, attractive vignette and light fall off towards corners
Extremely good value for money (look at the saving over buying alternative full frame video solution like Canon 1D X / 1D C)
Protects investment in existing glass
Match glass between full frame camera and Sony E-mount camera on multi-camera shoots
Corrects some optical defects in centre of the frame such as purple fringing and coma
In-camera electronic aperture control for Canon lenses on Sony body
Micro Four Thirds support in pipeline for March (and electronic adapter in June)
Turns Blackmagic Cinema Camera into Super 35mm (matching Alexa)
Every lens now has dual focal length and aperture (use with or without adapter to change crop)
More creative possibilities
Excellent build quality
Very small and light
Tripod mount
Infinity focus tuning built into the adapter and straight forward to use

Cons

Corner and edge sharpness a bit of a struggle with most legacy glass at fast apertures
Soft corners and edges most noticeable at infinity focus with fast apertures or wide open
Speed of auto-focus in need of improvement (painfully slow compared to same lens on a Canon body)
Some lenses are not yet fully supported by the electronics"

ROTFL. Jak generalnie szanuję opinie lensrentals, to tutaj pojechali...
To może być alternatywa co najwyżej dla korpusu typu 5D MkII, nie 1DX.
To tak, jakby maluch po tuningu miał być alternatywą dla Subaru Imprezy :-)
