Sony A6000 Replaces NEX-6

Image
Hands On with the Sony A6000


Sony A6000 Available for Pre-order
Here is a quick look at the newly announce Sony A6000 camera. It replaces the Sony NEX-6 but keeps the same form factor. The big improvement is the 24 megapixel sensor up from 16 mp on the NEX-6. It also boasts the fastest AF for an APS-C mirrorless camera with focus lock in 0.06 seconds. The speed burst is bumped up to 11 fps. All this while keeping the same NEX-6 price for the A6000 body at $648.

The silver looks a bit like champagne and looks handsome with the black grip. This announcement has us excited for the NEX-7 replacement.

Zeiss Touit 12mm f/2.8 in Cape May

Image
We thoroughly enjoyed the Zeiss Touit 12mm f/2.8 Distagon on a recent trip. We spent a few days in Cape May, NJ with the Touit 12mm glued onto the NEX-7.

We are still learning this ultra wide angle lens, at 18mm efov on the NEX, most everything will be in frame. We are somewhat addicted to the NEX-7's level feature which helps minimize converging vertical lines with such a wide lens. We also depended on the NEX-7's autofocus mode while using focus-recompose to frame. Here are a few shots from the trip. They are all RAW converted shots.













Sony A7 Hybrid vs Contrast Detect Autofocus

Image
Sony A7 Hybrid Autofocus
It may not be obvious to us but the hybrid autofocus, phase + contrast detection, of the Sony A7 is faster than the contrast detect only focus. The A7r does not have hybrid autofocus, more from this previous post.

Sony A7r Eye AF in Action
Here's a new feature included in the Sony A7 cameras. It's called Eye AF and it helps one capture that perfect focus for portraits with the camera locked onto the eye of the subject. We can't wait to test this out ourselves. Will it work with manual focus cameras?

Sony A7r and A7 Focus Speeds

Image

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.

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 moirĂ© and colour artefacts. The enthusiast-oriented RX1R removes this low-pass filte…

Sony NEX-7 Rear Button Focus

Figure 1. Rear Button aka AF/MF Button Controls Autofocus.
Here's a way to autofocus using the rear AF/MF button instead of the shutter button. You can then separate focus from locking exposure with the shutter button half press. This will also prevent the lens from prefocusing when in AF or DMF mode.

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 Explained by Dr. Pollmann

Compact Lens for a Compact NEX System
Dr. Michael Pollmann Carl Zeiss Program Manager discusses the Touit Lens Line.
Here is Dr. Pollmann of Carl Zeiss discussing the Touit lens concept. The Touit autofocus lenses are designed for NEX cameras as was the Zeiss 24mm Sonnar. With the introduction of the Touit line, NEX owners have access to Zeiss' legendary lens designs, Distagon, Planar, and Sonnar. The first Touit lenses will be available around June.

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.

NEX-7 with Speed Booster vs Nikon D600

Sony NEX-7 with Speed Booster vs Nikon D600
TheCameraStoreTV posted their hands on video with the Metabone Speed Booster for NEX cameras. They used the Canon EOS to NEX Speed Booster lens adapter on the NEX-7.

In the video they compare the NEX-7 and the Nikon D600, a full frame camera, to see if there are perceptible differences. They used a Sigma 35mm f/1.4 DG HSM lens on both cameras. The exposures were set to be equal at ISO 200 and aperture set at f/8. The NEX-7 with the Speed Booster registered and aperture of f/5.6 due to the full stop of light from the adapter. The D600 registered f/8. The image above is a side by side comparison at 400% enlargement. Would you be able to tell the difference?

Check out the full hands on video with the Speed Booster below.

MxCamera posted their video of a Leica 35mm f/2 Summicron lens from 1960 on the Sony NEX-6 from 2012. The 52 year gap is bridged by a Contax G 28mm lens housing which has been modified to allow autofocus on NEX cameras. If only Dr. Mandler can see what his Summicron can do now.

Thanks MXcamera HK!
