Sony A7r and A7 Focus Speeds

Image
Sony A7r with Zeiss 35mm f/2.8 Sonnar
One of the major differences between the Sony Alpha 7r (A7r) and the Alpha 7 (A7) is their focusing systems. Both cameras have contrast-detection autofocus but the Sony A7 incorporates phase-detection autofocus for a hybrid system which adds speed and accuracy to locking focus. The videos show a slight difference in locking focus for both cameras. More information below.

The RhinoCam allows us to use NEX E-mount cameras with medium format lenses. The RhinoCam has lens adapters for Pentax 645, Mamiya 645, or Hasselblad V lenses. The NEX is mounted on a shift mount while the lens is fixed. The NEX is then shifted to cover the image circle projected by the medium format lens. Each image is then stitched by an imaging software.

Here's an in-depth video walk through of the RhinoCam.

Sony RX1R Removes Anti-Alias Filter

Sony Cybershot RX1R Full Frame Sensor
Sony RX1R Hands On with Olivia
The Sony Cybershot RX1R, R = resolution, takes away the Sony RX1's optical low pass (anti-alias) filter to improve resolution. Other cameras that offer AA less cameras are Leica, Nikon, and Ricoh. The RX1R and RX1 will co-exist and share the same accessories.

Here is the Sony RX1R press release.

A new sister version of Sony’s acclaimed Cyber-shot™ RX1 full-frame compact camera satisfies the most critical photographer’s hunger for sharper, more detailed pictures.

Building on the awesome imaging power of the RX1, the RX1R takes pixel-perfect picture quality to new heights. The model’s ‘R’ suffix denotes a further improvement in the pocket-sized camera’s already spectacular resolution.

In common with many DSLR cameras, the original Cyber-shot™ RX1 features an optical low-pass filter (OLPF) in front of the sensor to suppress unwanted moiré and colour artefacts. The enthusiast-oriented RX1R removes this low-pass filte…

Carl Zeiss Touit 12mm Distagon and Miami

Image
Delano Hotel South Beach
Here are some shots from the Zeiss Touit 12mm Distagon from Miami. It was a quick trip and the weather did not cooperate. The 12mm Touit is a nice match for the NEX-7 due to its lightweight design yet being so well built. The lens was glued to the NEX-7 for most of the trip. The 18mm FOV will take more practice since it's such a wide perspective.

Zeiss Touit 12mm Lens in Istanbul Not Constantinople

Image
The plan: spend the 5 hr layover in Istanbul Ataturk Airport to visit the Asian side of Istanbul by ferry.

The plan was devised by my friend and I with no planning. Our other companions stayed behind and wished us luck since we needed it. First one needs a $20 visa to enter Turkey, this took 15 minutes. Next was the passport check line, this took 25 minutes - we have 4 hrs and 20 mins left before our plane left to our final destination. The easiest way to get into Istanbul is by the Metro. We had to take the Subway then the tram to the ferry. Luckily we had no map and were depending on strangers to get us to our destination. We arrived at the ferry one hour later with no complications except for the slow and jam packed tram - 3 hrs and 20 mins to go.

And the problems began. We were told that the ferry was free - it was not. We had to scramble to get tokens - where did the Turkish Liras go? We were rushing to catch the next ferry, and did not confirm its destination. We b…

Zeiss Touit Lenses for NEX Cameras

Image
Carl Zeiss Touit 32mm Planar
Touit, pronounced "do it," is the new name of Carl Zeiss autofocus lenses for NEX cameras. There will initially be three Touit lenses, 12mm, 32mm, and 50mm. They are expected to be available by the summer.

From the Carl Zeiss camera lens blog:
Touit is pronounced like the English “do it.” Touit stands for good visibility, agility, mobility and diversity, qualities which also aptly describe the new ZEISS lenses for mirrorless camera systems. The name Touit comes from the band-tailed parrots. This bird is very small and agile, and its plumage is deep green. The Touit parrots live in Latin America and the Caribbean in a wide range of different habitats, from damp-tropical island regions to lowland rainforests to thorn-bush savannas and even high in the Andes Mountains at altitudes of up to over 20,000 feet.
Please check our previous post for details on the three Touit lenses from Carl Zeiss.

Voigtlander 21mm Ultron Aspherical on Sony NEX-7

Image
NEX-7 with Voigtlander 21mm f/1.8 Ultron via Novoflex Leica M to E-mount adapter.
TechTalk with Ron Sheffler tested the new Voigtlander 21mm f/1.8 Aspherical Ultron against three other Leica M 21mm lenses on the Leica M9. He also used the lenses on the Sony NEX-7 and found that the Voigtlander 21mm f/1.8 the best at farther distances and large apertures. The Leica 21 f/3.4 Super Elmar-M came in second, the Zeiss 21mm f/2.8 Biogon in third, and the Leica 21 f/1.4 Summilux at the back of the pack. At f/4 all the lenses performed equally well on the NEX-7's APS-C sensor.

Here are some samples from the NEX-7 and the Voigtlander 21mm wide open at f/1.8. You can see more samples at TechTalk.
