Hi All


just sharing my personal likes and dislikes about the A9, after using it extensively for 2 weeks , keep in mine I was shooting with the D750 before this.   The fist thing that hits you in the face the AF wow fantastic speed accuracy coverage face and specially eye focus just hats off to Sony for this. the fast fps buffer no black-outs silent-shutter battery life all in a small body what can you ask for more. I haven't done any videos so can't say much about that but was disappointed not having time-lapse and I really liked that feature and used it a lot with Nikon. The AWB doesn't do a great job indoors and in low light conditions also the metering tends to be jumpy a bit but these are not big issues. Skin tones is probably the most frustrating thing for me personally but not in bright natural lights only when shooting indoors and low light conditions which I do a lot I just cant get the colors I want. With the Nikon It was easy to change the colors when they where off but I find it hard with the Sony. Some times the skin tones are over saturated with a orange color-cast that can not be removed easily without messing up the whole image if anyone has tips about this pls share. I wrote to a blogger who was complaining about this issue and he said he's waiting for a firmware up date to correct this but I kind have my doubts that this will be addressed.

Also I found vertical banding in a few shots not in very ISOs just normal conditions and personally think its from the electronic shutter but can't be sure. Very few not too many so not a big issue and maybe it could be addressed by Sony not sure.

If any of you guys has done a comparison between the RAW files with E-shutter and M-shutter high ISO I would love to see that. Too lazy to do it my self :).

So over all a great camera with a fantastic AF system and full of great features and before I forget I shout 3600 Raw files in a day with a single battery and still had around 38% juice left why on earth didn't they do this with the A7s I have no idea. only 2 things that I preferred from the D750 are having times-lapse and the RAW files.

2 examples of banding I (Ironically in the second banding example its and orange line)




Focal length: 200 mm
Shutter speed: 1/1000 sec
Aperture: F2.8
ISO: 1600
Exposure comp.: +0.30




Focal length: 200 mm
Shutter speed: 1/500 sec

Nice little review.

#1 makes me wonder if it's HSS banding? Was there a flash involved?
#2 I'd chalk down to a bad read from the SD card, was it present even when viewing the file on the camera or did it appear once you got the image on the computer?

no flash involved, I never viewed it on the camera I was busy shooting at that time, the SD card is the new Sony SF-G Series UHS-II 128GB SDXC. I see your point in the second image but the first one looks like banding of some sorts but it's not a big issue as I have very few examples in thousands of shots I took. I really it's not and issue for me at all

You moved from Sony/Minolta to Canon to Nikon before, you didn't struggle with skin tones with those switches? Isn't it just a mater of getting familiar with the colour response?

I loved the character of the pictures taken with the A9 you posted here until now - but then, in the past I also loved the way you processed your pictures, so that may be you and not the camera!

That banding is a thing. The word on the street is that it is indeed the E-shutter in some specific situations and it shouldn't be a problem with the mechanical shutter. But that is just hearsay

Mechanical shutter gives you 5fps with shutter sound and black-outs or freezes between frames so I wouldn't pay 1500$ for that let alone 4500$.

seriously I'm not worry about banding at all if it's in rare cases but I do struggle with the colors in doors just can't remove that damn orange without desaturating the whole image or messing up the back ground. I didn't have such problems with the Nikon Canon and the old KM But the old Alpha 700 I remember complaining about this and still they haven't done anything about it . with Nikon I get a yellowish color cast that is simply removed just can't do that with Sony there is no orange color channel to tweak. I know it's kind of hard to explain but I've seen many that have the same complaint

Just wondering if there were any other types of LED lights in the near surrounding which could have interfered here?

That looks like mixed light source situation with sunlight or cooler light in the background and warmer light on the subjects. The image looks balanced to the background light source.

I would try white balancing off a sample of the girl's white dress. The images look fine as is though. They might look worse balanced to the warm light source.

I shoot a lot in such conditions but usually can get the colors/skin tones right in a few steps but not soo much with the Sony RAW files I'm sure I will come up with something though. other then this I have no real issues with it and actually love this Sony camera    .

It seems to me that the white balance is a bit off in the last two pictures? Maybe a tad less yellow can help?

yes it was off about 90% of the shots that day shooting indoors, guess I will have to stop relying on it's AWB and set my own settings maybe.

If fully electronic shutter was used, it may be caused by the sensor clear down time and the mains flickering of artificial light sources. That's what was reported when there was an internet ****storm about it at release.

I am assuming the photos here were taken from raw. TO be honest, the Sony jpegs can give rather odd skin tones some times, depending on light (WB accuracy) and also the creative style used - the "portrait" profile is particular unappealing as it seems to accentuate pinks too much.

Many artificial light sources have high frequency switchers inside and these might give banding, perhaps?
A900, A58, 5d, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .
