Sony A7s First Impressions by Luminous Landscapes

sony a7s first impression luminous landscape

Sony A7s with Zeiss 24-70mm FE ZA



Luminous Landscapes gives us their first impressions with the new low-light king, the Sony A7s. Read their A7s first impression here. They provide samples between the Sony A7s and the A7r to test the A7s' low light capability. Video capability is also discussed.

Here are some interesting quotes that we found.

  • Sony is producing more new and interesting cameras, in more categories, and with more new technology than the two market leaders combined.
  • a 12MP file from the A7s can be printed at a size of 16 X 24" when upressed to 360ppi.
  • There is something to the look of A7s files that reminds me of medium format,
  • At ISO 51,200 the A7s is quite usable with some moderate noise reduction
  • My only complaint is that the interface team at Sony forgot to add this feature (Electronic Shutter) to the twelve position Function menu.
    • Why not just keep Electronic Shutter as the default?

Sony NEX-5N Footage at 24 FPS 1080p

NEX-5N Low Light Footage and Touchscreen Demo



Here's a couple of videos from jpac83 showing NEX-5N footage at 1080p and 24 frames per second. The video above shows footage at ISOs from 100 to 3200 to demonstrate the NEX-5N's low light capability. The video below was shot at 24 frames per second for that cinematic feel. The NEX-5N is the first NEX camera that allows for 24 fps video.

Sony NEX SLR Magic Noktor 50mm Lens

slr magic noktor 50mm sony nex


Here is the SLR Magic x Noktor HyperPrime 50mm F0.95 for the Sony NEX E-mounhttp://www.blogger.com/img/blank.gift. That is correct the maximum aperture is 0.95 similar to that of the very rare Leica 50mm Noctilux-M priced at $10,495. The Noktor is priced at $1000 which is very close to the Voigtlander 50mm f/1.1 Nokton. This fully manual lens, with an FOV of 75mm on the NEX, will allow plenty of light onto the sensor for low light shooting.

We are waiting for sample photos to see how this lens from the new Noktor company performs, recently acquired by SLR Magic.

For more information check out Noktor.com.

Take a ride with the Sony NEX-5



OneBikeGuy takes us around on his bike via the Sony NEX-5 and the 16mm f/2.8 lens. The video looks great even with the low light from the streets of Shibuya, Tokyo, Japan.

Check out what the NEX-5 looks like mounted on the bicycle.

Sony NEX-5 Sensor Beats Canon 7d - DxOMark

sony nex sensor vs canon 7d
DxOMark tested the Sony NEX-5 and NEX-3 and found both to be more than capable. DxOMark found that the sensors showed excellent color depth, dynamic range, and low-light ISO performance. The NEX-5 topped the Canon EOS 7d dslr (by a slight margin), Olympus PEN E-P2, Panasonic Lumix GH1, and the Sony Alpha 450.

Here is DxOMark's disclaimer:
Disclaimer: This dxomark review evaluates only the selected camera’s RAW sensor performance metrics (i.e., Color Depth, Dynamic Range, and Low-Light ISO), and should not be construed as a review of the camera’s overall performance, as it does not address such other important criteria as image signal processing, mechanical robustness, ease of use, flexibility, optics, value for money, etc. While RAW sensor performance is critically important, it is not the only factor that should be taken into consideration when choosing a digital camera.

Sony Nex 5 in Low Light

Here is a video using the Sony Nex 5 in a very dimly lit subway in order to test it's low light capability.
