Reddit mentions of Sony ILCE7S/B Alpha a7S Mirrorless Digital Camera

Hi /u/BranFlake5 - Good question. In my view, the principal reason is price.

That said, the GH4 has a few other advantages over the A7s besides price and internal 4K:

• the GH4 records and outputs to real 4096x2160 DCI 4K as opposed to the A7s' 3840x2160 UHD
  
  
• the GH4 outputs 10-bit 4:2:2 4K as opposed to the A7s' 8-bit 4:2:0 UHD
  
  
• the GH4 has a longer-lasting battery
  
  
• the GH4 has several ergonomic advantages, e.g., the ability to use the shutter button to record video
  
  The [$2498 A7s] (http://www.amazon.com/gp/product/B00JIWXTXG/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00JIWXTXG&linkCode=as2&tag=battleforthew-20) is a fabulous camera - but I am very happy that I bought the [$1698 GH4] (http://www.amazon.com/gp/product/B00I9GYG8O/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00I9GYG8O&linkCode=as2&tag=battleforthew-20) and was able to keep the extra $800 in my pocket.

Hi /u/Wizard_Status - there are at least a couple of options you might want to consider [Referral Links]:

• The easy choice would be an [$1800 7D Mark II body] (http://www.amazon.com/gp/product/B00NEWZDRG/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00NEWZDRG&linkCode=as2&tag=battleforthew-20) (for its 1080/60p, reduced moire when compared to the 7D and the addition of a headphone jack).
  
  Here is a low light, slow motion example of what this camera can do:

• If you want the best low light camera you can buy below $3000, you should seriously consider a [$2498 full frame Sony A7s] (http://www.amazon.com/gp/product/B00JIWXTXG/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00JIWXTXG&linkCode=as2&tag=battleforthew-20) with the [$367 Metabones EF to NEX adapter] (http://www.amazon.com/gp/product/B00COIWJKA/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00COIWJKA&linkCode=as2&tag=battleforthew-20).
  
  With this adapter, you'll have video autofocus, auto aperture and image stabilization with your Canon lenses mounted on the A7s.
  
  Here is what this camera can do with Canon EF lenses:

  I left the Canon 5D Mark II and Mark III off the list because neither camera can record at 1080/60p.
  
  Hope this is helpful, good luck with your decision and Happy New Year!
  
  

A used A7s I with your choice of lens.

It says on the video description:

>Filmed with Sony a7s and Canon 5D Mark III RAW

Amazon links: A7S Canon 5d III

Lenses can cost anywhere between $300-$3000 depending on the type. Cine lenses can be a bit cheaper than photography ones since they don't need fancy features like autofocus and image stabilisation. Most video guys prefer to do everything manually.

It's amazing what consumers and amateurs can afford these days as technology progresses!

Congrats!

I started off my career with a T2i and similiar lenses. Besides camera, my first 'big' investment was in this lens. I purchased it over 5 years ago for about $600, and I could sell it today for around the same price.

For this particular shoot, I suspect the interior lighting to be much too dark for your camera and lens selection. The nifty fifty will suffice, but will be very limiting due to crop factor and focal length. You are going to want better low-light lenses such as the Tokina 11-16 f/2.8, or the Sigma 18-35.

Honestly in your situation, I would rent the Sony A7S, Speedbooster, and the 24-105 for this shoot. Conversely, you might be able to use the GH5 with the 12-35 if the lighting isn't too terrible.

You'll be much better equipped with those choices, even though it will cost a lot. But, portfolio may be more important to you now than making a few hundred bucks.... you'll have a much better end product with better gear which will serve your portfolio well.

some say the sony a7sii "makes light", rather it is just great at low light capture and has amazingly clean images/video at a high iso. That combined with a lens with a wide aperture and you get great performance. I would recommend you get a sony a7s mk1 or mk2 or a sony a6300 or a6500, depending on your budgets as all have fairly good low-light performance with the a7sii being the best of them. As for a lens, you could go for an adapter to use your canon lenses but if you do not have a canon lens with a nice wide aperture like f/1.8 or better, it would be good to pick up a lens like that. If you choose to move entirely to sony as so many people have recently, you will want a good all around lens too. Let me know if you need more help!
