Focal Reducer 0.72x with EF mount [m4/3] first impressions

Last time I've presented you a simulation on how a focal reducer (FR) 0.72x might work with Tokina 11-16 mm 1:2.8 on micro 4/3 sensor. Today I decided to present you first impressions on $99 eBay version of FR with EF mount.

Focal Reducer 0.72x with EF mount for Micro Four Thirds (MFT M4/3)

What is Focal Reducer aka Lens Turbo aka Speed Booster?
The simplest answer is that it's the lens that focuses light from a mounted lens reducing focal length by a ratio (in this case 0.72x, which means 100 mm lens becomes 72 mm). It also makes lens faster (in this case by 1 EV step - f2.8 becomes f2.0, f2.0 - f1.4 and so on...).

Yesterday I've finally received my own FR. I must admit it's very well built and quite heavy. It didn't gave me the impression of any cheap materials used. Rather firm and dependable hardware.
All my life I've been an Olympus, then 4/3 and now micro 4/3 person. Obviously I don't possess any Canon lenses, and that's why I ordered EF > M42 adapter with flange (for M42 lenses with aperture pin). It fits perfectly and makes whole unit even heavier.

Here it is. One of my favourites: 85 mm and 1.7 aperture. Isn't that too good to be true?

I've found it in 2008 on Polish auction site and bought it immediately. It was a really lucky shot that time, because price was 1/5 of usual price for that kind of lens. I was pretty anxious if quality will work it, but as it turned out... well, you can see.

All pictures were taken on aperture priority with F1.7, camera Lumix G2.

Mount: M4/3 > 4/3 > M42
