Sony A7S-3

Previously, I shared the Sony A7s press conference unveiling and a rudimentary ISO test of the Sony A7s with several sample images at 100% shot on the show floor for NAB 2014.

As you may recall, the Sony A7s was announced alongside a new 28-135mm cinema power zoom lens. Here is what the lens looks like attached to the Sony A7s. [click to continue…]

Sony A7S

Aside from the 4K capability, one thing everyone is talking about on the new Sony A7S is the new 12MP sensor and the ridiculous low light sensitivity that it delivers.

I got some hands-on time with the Sony A7s today and took several shots at various ISO levels. Below, I have assembled 100% crops of the images from the center of the frame from ISO 100-102400. [click to continue…]

I just got my hands on the Fuji X100, and after reading all the praises this APS-C format camera has received for its image quality, I wanted to take a closer look.

Below you will find a chart that covers the sensitivity range of the Fuji X100 for both RAW images exported via Lightroom 3 and in-camera JPEG images. [click to continue…]

Nikon D3s – ISO 3200 – f/2.8 – 1/1000s

One of the three components of exposure of photographs is the sensitivity of your image sensor or film inside your camera.  This measure of sensitivity is expressed as ISO speed – and it’s kind of a big deal when your light is less than ideal. [click to continue…]

Yesterday, I showed off a little of what Lightroom 3′s noise killing prowess could do.  And then, I started looking back at some of my basketball photos from this season, most of which were shot at ISO 3200.  Some of them could use a little help from Lightroom 3′s noise reduction panel; however, some looked just fine, even with a little bit of grain.
