Sony A7r Weather Sealing Test with 28-70mm FE Kit Lens


Kai Wong of DigitalRev Plays with the Sony A7 Cameras


The new Sony A7 and A7r cameras are featured on Digital Rev with Kai Wong. The A7's 28-70mm FE Kit lens was used on the A7r and produced "stellar" shots. The A7 and A7r's focus systems were compared. The water resitance was also tested using the A7r and the 28-70mm kit lens. A Leica 50mm f/0.95 Noctilux-M ASPH was used to show how adaptable the E-mount is. The focus peaking display was nicely featured. In conclusion, Kai was impressed with both cameras, "Sony has created a product of desire."

Sony A7 and A7r Hands On at PhotoPlus Expo

Sony A7r with a Voigtlander 12mm Lens and Viewfinder


It was a very crowded Sony booth at PhotoPlus. The great thing was the Sony representatives were very accommodating to anyone who wanted to play with the new Sony A7 and A7r. We had our bag of lenses and was able to mount them all on the A7 and A7r - check out the 12mm viewfinder on the A7r above. The lenses include the following:

  • Voigtlander 12mm f/5.6 Leica Thread Mount on a helicoid adapter.
  • Voigtlander 35mm f/1.7 Ultron LTM.
  • Minolta 24mm f/2.8 Rokkor MD.
  • Contax G 28mm f/2.8 Biogon.
  • Contax Zeiss 85mm f/1.4 Planar with the Metabones Speedbooster and the standard C/Y adapter.
  • Zeiss 12mm f/2.8 Touit Distagon.
The cameras were pre-production and the use of memory cards to record the images was prohibited. We wanted to see if I could see immediate problems on the rear tilting lcd but none were glaring.  The only noticeable issue was color shift with the Contax G 28mm Biogon.  We're hoping that this can be remedied with the production models.

Below is the Contax 85mm Planar on a Metabones Speedbooster. As you can see it cannot cover the whole sensor but with APS-C mode on the A7 cameras the Speedbooster is still useable.

The Voigtlander 35mm Ultron LTM was a nice surprise.  This lens gives the NEX-7 some problems with color shift but on the A7 this was not the case.  The few snaps that we took looked great on the rear lcd.

The Minolta 24mm f/2.8 MD provide a nice wide angle image on the Sony A7.  It felt nice and balance on the slightly larger frame of the Sony A7.

We were very excited to mount the Zeiss 12mm f/2.8 Touit on the new Sony A7.  We had the A7's APS-C lens detection off to see how much the Touit can cover the full frame sensor.  The lens has a plastic shroud to protect the rear element and this showed up in the shot below.  The Touit works perfectly fine in APS-C mode.

Sony DSC-RX1 vs Leica M Type 240


TheCameraStoreTV posted their review of the Leica M Type 240. They also brought along the Leica M9 and the Sony DSC-RX1 to compare. The Leicas were fitted with the Leica 35mm f/1.4 Summilux, while the RX1 comes with the Zeiss 35mm f/2 Sonnar. The RX1 image had a slight advantage over the M Type 240 in both low and high ISO shooting.

Check out the full review by the Camera Store below.

DxOMark Sony NEX-7 vs Leica M 240

Leica M Type 240 vs Sony NEX-7 Sensor from DxOMark


DxOMark published their analysis of the new Leica M Type 240's sensor and we compared it against the Sony compact heavyweights, the NEX-7 and the Sony DSC-RX1. The NEX-7 is about the same as the new Leica M in the color depth and the dynamic range scores. It just fell short in the low-light ISO score which we can attribute to having an APS-C sensor compared to the Leica M 240's full frame sensor. We are hoping that the upcoming Sony NEX-7N will have ISO 50 to improve that score.

But the full frame sensor of the RX1 is somewhat ahead of the new Leica M Type 240 according to DxOMark's measurements.

Sony NEX-7 with Leica 60mm Macro Elmarit-R

Here are a few shots from Old Sturbridge Village using our newly acquired Leica 60mm f/2.8 Macro Elmarit-R on the Sony NEX-7. The Leica 60mm Macro is said to have "excellent image quality at close-up range..." and "superb results at greater distances" when stopped down. We used the Macro Elmarit-R wide open all day at f/2.8 and only stopped down to f/5.6 when the depth of field was needed. The NEX-7 was set to Aperture Priority and ISO 100 outdoors or Auto ISO indoors. A basic Leica R to E-mount lens adapter was used.

The NEX-7 with the Leica 60mm is a nice match in good light. We had no problem of keeping the shutter speeds up at f/2.8 in snowy New England.

The Leica 60mm Macro Elmarit-R has a long focus throw and focusing indoors takes some practice with moving subjects. The focus ring is well damped and provided nice feedback for critical focus.

We don't shoot Macro too much but that can change with the Leica 60mm with the 1:1 adapter. Here are shots at f/2.8, f/8 and f/22 at minimum focus distance.

Voigtlander 21mm Ultron Aspherical on Sony NEX-7

sony nex-7 voigtlander 21mm 1.8 ultron

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.

NEX-7 with Voigtlander Sigma and Fuji Lenses in Turkey

NEX-7 with Voigtlander 15mm, Sigma 30mm, and Fujinon 50mm lens


Here is a set of pictures by Emmanuel C. taken in Turkey with his Sony NEX-7. He brought along a pair of adapted manual focus lenses: Voigtlander 15mm f/4.5 Super Wide Heliar and the Fujinon 50mm f/1.9 lens. He also used the native E-mount autofocus the Sigma 30mm f/2.8 DN lens. This provides a nice set covering 22.5mm, 45mm, and 75mm equivalent field of view.

Leica M - Target of the NEX System

The new Leica M



This is the new Leica M camera and this is where the NEX system should be headed. The Leica M has technologies proven in NEX cameras such as focus peaking, detachable and tiltable electronic viewfinder, accepting other lenses via adapters, and a movie mode. The Leica M adds the following to the NEX system: a full frame sensor, rangefinder focusing system, a weather proof body, and a GPS accessory. The Leica M will be around $7000, around 6x the cost of the Sony NEX-7. Kudos to Leica.

Voigtlander 21mm Ultron NEX Friendly?

sony nex voigtlander 21mm ultron leica

Voigtlander 21mm f/1.8 Ultron



Here is a new Leica M mount lens from Voigtlander. It is a fast f/1.8, 21mm wide angle lens. This translates to 30mm (effective FOV) for the Sony NEX sensor. The big question is, will it play well with the APS-C sensor? We are hoping that it does and give us a fast, wide angle lens similar to the Zeiss 24mm f/1.8 ZA E. The manual focus and aperture, Leica M mount, Voigtlander 21mm f/1.8 Ultron will cost £1149. It is almost twice the weight of the Zeiss 24mm.



21mm f/1.8 Ultron Specs from Voigtlander Germany:

Due to its large diameter elements, you can shoot with available light even in severe light condition, and also shallow depth of field and super wide angle, this mix of features offers you a chance to emphasize main things with great bokeh.
Any kind of aberration is corrected properly by the construction of 13 elements 11 groups with Aspherical element.

RX1 35mm Sonnar Lens MTF Chart

Sony RX1 35mm Zeiss Sonnar Autoocus Lens

Sony RX1 35mm Sonnar Lens MTF Chart
at f/2 and f/8; 10 and 30 lp/mm



Here is the calculated MTF Chart for the 35mm f/2 Sonnar lens on the Sony DSC-RX1. We will try go give a quick explanation of the RX1 MTF charts above. The red lines show how well contrast will be reproduced by the lens. The green lines show sharpness or resolving power of the lens. The higher on the chart the better. The horizontal axis represents the point from the center of the lens. This tells us the corner performance of the lens.

The Sony's RX1 35mm Zeiss Sonnar lens as described in the press release:
Complementing the full-frame sensor is a fast, bright Carl Zeiss Sonnar T* lens with a fixed focal length of 35mm – a versatile choice for portraits, street photography and everyday shooting. Recordable dynamic range is reduced at sensitivity levels below ISO100. Full-frame Image Sensor APS-C Image Sensor3 Derived from the German word “Sonne” (“sun”), the Sonnar name reflects the ability of the lens to capture as much light as possible. This premium lens features newly designed optics including an Advanced Aspherical (AA) glass element. This contributes to the camera‟s extremely compact palm-sized dimensions while keeping extremely high performance of the lens.

The lens‟s wide F2 maximum aperture and 9-bladed circular aperture enable beautiful "bokeh‟ (defocus) effects. A Macro switching ring on the lens barrel instantly shortens minimum focusing distance to just 20cm (from image plane), making the Cyber-shot RX1 ideal for capturing small close-up subjects with exquisite detail.


Below are actual measured MTF charts for the other 35mm f/2 compact lenses, the Zeiss Biogon and the Leica Summicron. Calculated and measured mtf charts should not be compared but we wanted to see what the Sony and Zeiss engineers were targeting when they designed the 35mm Sonnar lens for the RX1.
