I would - but a year later than I did.Now I hope is a good time to send in my D800E to have the left autofocus problem repaired.Regards, K-H.

Hi there,Those are the Sangre de Cristos mountains in the Rockies.Top right is the Santa Fe Ski Area, NM.Straight ahead is Santa Fe Baldy.Way to the left, through the trees, is Truchas Peak,...

Sony NEX-5N + METABONES L/R - E mount Speed Booster + Leica Vario-Elmarit-R 1:2.8-4.5/28-90 ASPH.A useable image? Thanks for your feedback.With best regards, K-H.

Cool!Thanks, K-H.

The following images are from NEX-7 + MSB + Leica Vario-Elmarit-R 1:2.8-4.5/28-90 ASPH.FL is 28 mm, f/2.8, OOC JPG, no post processing. One can clearly see the image quality degradation in the...

So, I finally got a Leica Vario-Elmarit-R 1:2.8-4.5/28-90 ASPH.On the NEX-7 with Firmware Version 1.02, this lens didn't show vignetting to my eyes at any focal length or aperture.  However, it has...

+1 indeed!Not to forget Jono's MM images from China.with best regards, K-H.

Hi Tom,Thanks for the info.I would get in touch with Metabones and have the unit checked out and if necessary replaced.Good luck.With best regards, K-H.

Here is one more example:Sony NEX-7 + Metabones Speed booster + Leica Summicron 1:2/90 @ ISO=100, 5s, f=5.6.  Image processed and vignetting corrected.Best, K-H.

Hi there,What do you have in mind shooting with your camera?  The answer may depend on that.I own both for different reasons.The OM-D E-M5 has several benefits, In-Body-Image-Stabilization IBIS and...

Gianluca,Take care, until then, so long, and good luck.K-H.

Hi Gianluca,Am I mistaken as I only see smiles on the faces of some ladies.Cool shots!  Very moody.  You have done well!  More Please.  Thanks.Best, K-H.

Hi Quercy,From my limited experience I have to conclude that vignetting is more troublesome the longer the lenses are and the wider the aperture used. Stopping down the lens really makes a big...

Here is another shot with the same configuration:Sony NEX-7 + METABONES L/R - E mount Speed Booster + Leica APO-Telyt-R 1:3.4/180Again, shot wide open at nominally f/3.4 but effectively at...

The following images are from this configuration:Sony NEX-7 + METABONES L/R - E mount Speed Booster + Leica APO-Telyt-R 1:3.4/180Shot wide open at nominally f/3.4 but effectively at f/2.4, ISO=800,...

You write:"BTW it is interesting that in Khaw samples, there is no heavy vignetting in the extreme corners. My EF/NEX version shows vignetting at all lenses above 35mm and it is getting worse as...

Here is another set for the same cofiguration:Sony NEX-5N with EVF + METABONES L/R-E mount Speed Booster + Leitz Ring 14127 + Short Focus Mount 16464 + Tele-Elmar lens head 135/4 + Hood 12575Focus...

Here are OOC JPG images, successively being stopped down, starting wide open, for this configuration:Sony NEX-5N with EVF + METABONES L/R-E mount Speed Booster + Leitz Ring 14127 + Short Focus...

So, there is some corner degradation as one can see here:http://www.dpreview.com/articles/2667195592/first-impressions-metabones-speed-booster Having used my Speed Booster for short tele lenses, I...

I am very happy with the Leica R version of the Speed Booster and am looking forward to the Nikon version. As I am used to manual focus lenses poor AF is a non-issue for me.

Vignetting is more...
