Focus Stack Test with the Leica 60mm Elmarit-R

8 Images Blended Together.


Here is the Lysudamuloa Red Jewel in full bloom. We wanted to try out focus stacking with the Leica 60mm Macro Elmarit-R. The aperture was set at f/5.6 which we assumed was optimal. The image above at 45˚ was a stack of 8 shots aligned and blended together with Photoshop.

Sony A7r at Mardi Gras World New Orleans

Face to face.


We took a break from eating oysters in New Orleans and took a quick tour of Mardi Gras World. Mardi Gras World supports a third of the floats that are paraded on the days leading to Fat Tuesday in February. They are responsible for the design and upkeep of all the decorations on the floats.

The tools at hand were the Sony A7r and the 40mm M-Rokkor. We shot in Aperture mode, seemingly stuck at f/2.4. Sharpness at f/2.4 is substantially better than wide open at f/2.0 on the Minolta CLE lens.

Hands On with Zeiss 35mm Distagon on Sony a7r at Photo Plus

sony a7r zeiss 35mm distagon leica samples

Zeiss 35mm f/1.4 Distagon on the a7r


Here is the newest Zeiss lens for the Leica M system. It is a Distagon 1.4/35mm ZM lens - Carl Zeiss' fastest lens for rangefinder cameras. We stopped by the Zeiss booth at Photo Plus and tried it out on the Sony a7r with a close-focus adapter. Voigtlander makes a better version of the adapter but this one works for us.

The 35mm Distagon ZM feels like a fine piece of machinery. The aperture from f/1.4 to f/18 have soft click stops. The focus ring is smooth, well damped, and pleasing to use - we prefer it to the Otus' ring. The lens is dense and heavy for such a small size thanks to the all metal construction. The 35mm Distagon ZM is deceptively heavy as the 85mm Otus ZE is deceptively light.

Zeiss 35mm Distagon ZM Announced

Mockup of Zeiss 35mm f/1.4 ZM on Sony A7r


Carl Zeiss announced their fastest ZM, Leica M mount, lens at Photokina 2014. The new Distagon T* 1,4/35mm ZM is designed for the Leica M digital sensor but we are hopeful that it will work well on the Sony A7 cameras with the appropriate lens adapter. Above is a mockup of what the Zeiss 35mm f/1.4 lens would look on a Sony A7. The Zeiss 35 f/1.4 will provide subject isolation through shallow depth of field.

Will replacing the standard Sony A7R's ifrared cut-off filter with a clear filter improve rangefinder lens performance? Compare the images above from genotypewritings to see what your conclusion is. Read more about the full spectrum Sony A7R at genotypewritings.

Voigtlander 12mm Ultra Wide Heliar Sony A7r Samples

Here are some shots of Brooklyn produced by the Sony A7r and the Voigtlander 12mm f/5.6 Ultra Wide Heliar. This is the 1st version of the 12mm lens in Leica M mount.  You can see the color shift but it's not intrusive for these snaps.  The Voigtlander 12mm is compact and looks great on the A7r.

Trainspotting with the 40mm M-Rokkor and Sony A7r

sony a7r 40mm m-rokkor leica

Here are some test shots with the Minolta 40mm f/2 M-Rokkor for the Minolta CLE. This is the multicoated version of the Leica 40mm Summicron-C. We used the very compact 40mm M-Rokkor walking around a local train museum with the Sony A7r via a Leica M lens adapter. The shots up to the handcart are all done at maximum aperture of f/2. Manual focus was very easy with using the viewfinder magnification of the A7r even in the mid-day sun. The mid-day sun also guaranteed high shutter speeds at ISO 100 and f/2. All the shots are handheld.

The shots below are at f/5.6 up to f/11. We need to test this lens more but the sweet spot is definitely at f/5.6.

Sony A7r with a Minolta 40mm f/2 M-Rokkor via Leica M Adapter


The lens has been great on the Minolta CLE and NEX-7 and it performs well on the full-frame A7r. The lightweight and compact 40mm M-Rokkor with a fairly fast f/2 aperture should always be considered for the A7 if you want to try Leica M lenses.

Sony A7r with Konica Hexanon 57mm f1.2

sony a7r konica hexanon 57mm 1.2

Sony A7r with Konica Hexanon 57mm f/1.2 shot by NEX-7 with a Leica 60mm Macro-Elmarit-R


Here are some of our test shots from the Sony A7r and the Konica Hexanon 57mm f/1.2 lens. The lens was mounted on the A7r using a Konica AR lens adapter. We wanted to test out the lens at f/1.2 the whole time and it was fitted with a 4X ND filter to battle the sun. The 1/8000 shutter speed and 50 ISO of the Sony A7r helped at times as well.

The Konica 57mm played very well with the A7r per our standards. All the shots were handheld as we rarely use a tripod. The focusing, at such a shallow depth of field from the large f/1.2 aperture of the lens, was manageable on the A7r. The weight of the lens would make us think twice of walking around with it but the results are hard to argue with. The details shown at f/1.2 is remarkable even at the outer edges of the shots.

It was our first time playing with RAW files from the Sony A7r. We used Raw Photo Process to process the 36 MB RAW files to 218 MB tiff files - our laptop was straining a bit. The files were then finished off in Aperture. We need to tweak our workflow since we are still using our NEX-7 processing.

P.S. The shot of the A7r and the Konica 57mm was taken by the NEX-7 using wireless flash with the F20AM as the controller and the F43AM as the slave. Experimenting with wireless flash was fun.
