A7s moire?
In: Cameras
This is a frame taken by my Sony A7s with PP4 25p Full frame
Take a look at the tie. The picture speaks for itself.
I thought that the A7s didn't have aliasing and moire, at least not in FF 25p mode!

Andrew, don't you know if the picture from the A7s matches the one from the D750, someway?I was thinking that using for istance the Sony Cine2 PP6, it is less versatile then the S-log2 PP7 but it doesn't need to be graded so much. Maybe it behaves closer to the D750 flat profile then the S-Log.In this way A7s and D750 can work in the same set as camera A and camera B without many postproduction problems.

According to the Al Jazeera reporter Miguel Toran the Viltrox Mark II is better than the Metabones Mark IV. And it's much cheaper.
Has anyone tried it? Can anyone confirm that? -
Good news! Now I'm curious to know which is better between the Metabones Mark IV and the Viltrox Mark II

A7S Adaptors
In: Cameras
But with the Metabones adaptor (EF to E-mount) mark III or IV, how does a OIS lens, such as the Tamron 24-70mm F2.8, performs in terms of stabilization with the A7s? As far as I know the AF is slow. I hope the rest is ok.
-
The E mount is the same regardless. ALL the simple adapters listed as for NEX work with the A7 (maybe not some of the Sony LA-EA# ones though). It is the lenses that may or may not cover the full sensor of FF. Most normal E mount lenses do not fully cover the FF sensor. Some of them do. The Samyang/Rokinon/whatever lenses do cover the full frame sensor as do those labelled FE. Some of the normal E mount Sony lenses cover the FF sensor at least in part.
FF legacy lenses with simple adapters (like most if not all M42) will cover the full sensor. I use m42 lens to Pentax K adapters in a Pentax K to NEX adapter for my A7 (though have recently sold most of my m42 lenses and only have a couple of old oddball lenses left in m42).
Thanks Noone!So I'll buy the cheapest M42/Nex adapter on internet. It should be fine, I think. -
Guys I have many M42 lenses and the A7s is the camera I'd like to buy.
One question: Is there a compatible M42 - E-mount adaptor to cover the A7s full frame sensor?There are many M42/Nex cheap adaptor on internet but I don't know whether or not they work with Nex (Apsc) cameras only.If not with one adaptor, is there a way to fit a M42 lens in an A7s body (maybe with 2 adaptors)?
can someone recommend to me the best way? Thanks! -
Who knows how much time Sony needs before we see a faster rolling shutter in a Sony camera.Maybe one more year. I don't think at Photokina we'll see a new camera with this patent.
Anyway it is a good news! -
Unfortunately there is visible aliasing in the clip
-
Hi David, thank for your experiments!The rolling shutter issue seems drastically reduced. The image looks smoother in APS-C but I think that a little of sharpening in post could solve this problem. I see a little bit (very little) of aliasing sometime (in the handrail 1'24") but I'd say that in APS-c mode the A7s can be handheld with no worryes.
Did you use OIS lenses? -
I don't know which camera has the worst rolling shutter.Sony promised an improvement of that with the definitive firmware but at the moment the A7s rolling shutter takes 30.5ms.I hope in a quick firmware update!

Hi Andrew,
is the HDMI out of the A6000 422 or 420? 10bit or 8bit? would it be great with a Ninja Blade, in your opinion?
A6000 + speedbooster + Ninja Blade would cost approximately like the GH4 and less than a 5dMarkIII.I hope the rolling shutter is not really annoying.

Pocket Cinema Camera (Raw Video)?
-
The Ikonoskop is expensive, it has a smaller sensor and records just at 1080p
-
Is there a chance to get more dynamic range with the new firmware through HDR using the 50p?
A7s moire?
