Sony Alpha A7s Sample Photos – Initial Impression and Forum Updates

sony-alpha-a7s-back

I’ve had the Sony Alpha A7s for about two weeks or so now, and I took a lot of sample photos so far using the FE 35mm f/2.8 Zeiss Lens and the Canon EF 135mm f/2 L Lens via the Metabones III Lens Adapter 😉

Talk about killer High ISO performance? Incredible is really the word for it and when you can just Willy nilly use ISO 20000 or even 100,000 and still get usable results, the times have officially changed. Yeah, the A7s is a game changer in the High ISO department by a significant margin.You can now hand hold with very little light in the room, and this has never been possible before at a reasonable price.

Using my older Sony Nex-6 as a base-line, the High ISO performance has not really improved beyond that and it’s been pretty much the same performance on the top end at around ISO 25,600.

The lower resolution A7s sensor (12mp) is much better than my A7r 36mp monster as far as high ISO is concerned and dynamic range. The raw files have more highlight and shadow information from what I can tell, but obviously much less detail due to the lower resolution sensor. If you don’t need gigantic prints, this full frame camera is going to be awesome for landscapes and everything else that needs to be captured.

Clearly a 4k monster, but also a photography camera by nature don’t forget 😉 If you strictly need a 4k all in one video camera, then the newer FDR-AX100 4k Ultra HD Camcorder is worth checking out (Click Here)

I’ve taken some video with the A7s so far and creating slow motion video footage is awesome! I will try and get some more sample footage including what the sLog2 gamma profile looks like on import so you can see what you have to work with.


Sony A7, A7r, or A7s?

Having both the 36mp Sony A7r and the 12mp A7s in hand, I would rather have the Sony A7s at this point personally for a few reasons. One being the insane high ISO abilities. Another being the silent shutter option and killer video capabilities. The build quality is basically the same from the outside and could still use a few slight tweaks. The Menu button for example is awkwardly way left and the lip that creates the inset for the lcd screen makes it harder to push also.

BHPhoto also did a great article comparing all three cameras side by side if you would like to check it out this way >>

 

Sony A7s Real World Sample Photos

Here are a few sample photos that I took so far with the full frame Sony A7s in various lighting conditions using the SEL35F28 lens. For more information on lenses, be sure to check out my E-Mount Lens Guide This Way >>

Starting off with the Z-Scene from my deck I was immediately impressed with the quality of the FE 35mm F/2.8 Zeiss lens. Awesome sharpness and bokeh rendering. The color and contrast is also very good in my opinion as you will see below.

Low Light

Here is a photo of Layla on the couch using just the television light for a source. First the Jpeg photo, then the raw photo so you can compare the on camera processing/ noise reduction. It did a good job in my opinion.

Randoms

The Jpeg images have more sharpening in some cases then I would prefer, but you can play around with those settings in the camera and fine tune them to your liking. I usually shoot raw, but have recently been enjoying the output of Sony’s jpegs on the A7s in particular. Here is another Jpeg image of an old tractor and the colors, contrast, and detail is excellent in my opinion.

Layla and I went to the park the other day and I grabbed a few shots at the playground 😉

The lighting inside the illuminated slide tunnel was a bit confusing for the camera, but I was pretty impressed with this jpeg result. Layla was at peek happy, just look at that face!

Sony A7s w/ Canon 135mm f/2 L Lens

Using the Metabones III electronic lens adapter allows for easy use of my older Canon pro gear that is still laying around the lab 😉

My Dad was cracking up about something we were chatting about and I had the Sony A7s on my Lap with the LCD screen aiming upwards so I could see it clearly. I actually prefer to use manual focus with focus peaking to get really close, and then use the focus magnify (C1 default) to confirm and fine-tune.  This works awesome in my opinion and really rings high on my photography fun factor! I love using killer primes even though they are limiting and harder to use in general, but the results are just worth the trouble always.

    Hey Jay,
    So if the A7R sensor is the D800 sensor, is the A7S sensor the D4 sensor?

    thanks!


  2. Jay! i recently picked up the A7S to see if it really is as good as everybody is saying. And unfortunately it is! Its got me on the fence about selling my A7R but when I do photoshoots the A7R provides a killer amount of detail and cropping potential. You can really make a macro shot out of a snapshot due to how razor sharp it can be if shot properly. Yesterday I did some interior shooting for a realtor. I took the A7S. I couldnt be happier! I used the in-camera HDR processing and the pics were amazing! It really is probably due to the dynamic range and smaller file sizes that in conjunction with internal processing, provided me HDR pics I was finally really happy with. The NEX6 and NEX7 did a fine job. I have never tried the A7R as the files are much to big, but did a test and felt the HDR images were smudgy and noisy. Not so with the A7S. Plus, the camera completes the processing extremely quickly.

    Thats all for now. I have also done some A7R VS. A7S high ISO tests. Seems the A7R hangs till 6400-12800 or so…. but the A7S keeps the dynamic range and color at a different level than the A7R even at those ISOs.

    Love your site and video reviews btw!

      Hi Juan,

      Sorry for the delayed reply and yes I totally hear ya about the A7r as I am in the same exact boat! The 36mp A7r detail and cropping potential is extremely useful at times and hard to give up. Interesting about the A7s Auto HDR compared to the A7r! I read your comment days ago and have since tried auto HDR on the A7s with great results. It seams to work about the same as my Nex-6, but the overall IQ is better because of the full frame sensor. I have some sample photos using all the creative modes and Auto HDR that I was going to post an article later today if I get to it 😉

      High ISO the A7r is really good for a camera of the times. ISO 6400 is high enough for most photography with the appropriate glass. The A7s takes it to an insane level though, where it doesn’t matter how dark it is almost!

      Thanks again for the comments,
      Jay

    Well ive just bought this camera as well and can say the photos are stunning. I have the Zeiss 55mm and its so sharp. Very glad I sold off all my Canon DSLR gear now. The AF I have to say is not as good as the 1DX was but the size and low light that I need for shooting in clubs totally outweigh the cons. Video is just a dream as well. 4.5 stars


  4. Jay

    Thanks for the comments Roland and I really hope that you would not expect the AF to perform as well as the 1DX? This difference is huge between the two cameras as far as price and hardware is concerned. The Sony has no mirror, so it’s really not even comparable to the 1DX in that regard in my opinion.

    I agree the a7s is a killer camera all around 😉
