The GH4 is an awesome camera by itself but adding a Metabones speedbooster with the Sigma 18-35mm f1.8 lens turns the GH4 into a full frame equivalent of a f2.8 zoom offering shallow depth of field as well as great low light performance from this smaller sensor camera. Take a look to see how it is done and if it is worth it.
Purchase the Metabones:
Nikon G to Micro 43
Canon EF to Micro 43
Both the A7s and 5D are a combination of photography and video cameras, but Sony definitively launched the A7s to appeal more to video while the 5D is still largely a photographer's camera. So in one sense it’s a bit unfair to go with this comparison because the 5D Mark III is a phenomenal still camera and is definitely the camera I’ll take for my wedding photography jobs, that said, there are quite a few videographers using the 5D Mark III for video, including me and so this comparison is for us.
Two brand new video cameras with different strengths going head to head is always a ton of fun. Not quite as fun as having to make the decision of which one of these cameras to purchase. We all know by now that nothing beats the A7s in low light and the 4k in camera shooting of the GH4 definitely has it’s advantages. So which one of these cameras should take its place in your camera bag, let’s find out in this review.
The Sony A7s brings the awesome capabilities of the original A7 and combines them with a new 12mp sensor making it a low light king, a ton of video features such as zebras and peaking, and records it all internally at up to 60fps @ 1080p internally or 4k and 30fps using an external recorder through the HDMI port. But is that enough to keep it alive as the competition increases in this video segment? Check out the full review after the break.
Purchase the Sony A7S
Either way this is a great video camera especially when you need tons of dynamic range for one crazy price! Better snap these up quick.
The new Sony A7s has a special trick up its sleeve....it can record a custom picture profile called s-log2. While not quite RAW, it does open up the dynamic range of the video file to better allow for grading and coloring in post. Check out the video past the break for a detailed look at how to enable the S-log2 profile in your Sony A7s (it's not labeled), how to edit the file, and what the results were. There are also some huge ISO limitations as well so check it out.
The Cameras are in so let the testing begin! Stay tuned as we put the Panasonic GH4 vs the Sony A7s vs the Canon 5D mark III. From low light results, camera features, and 4k, we will be going indepth with these cameras over the next few days. For updates on all the action, stay tuned!
If wedding or landscape photography gets too boring for you, we now have the solution. This story about a USAF Thunderbirds photographer, Sergeant Larry Reid Jr. will definitely wake you up, inspire you, and give you something to dream about. This has got to be one of the most amazing photography jobs around.
