Convince me: A7s, GH4 with Nikon Speedbooster, or FS100 with Canon Speedbooster?

Hey guys,

I'm having a lot of trouble deciding what to get for a camera. To start off, I mainly shoot mountain biking in low light environments, and I run a T3i with ML and Cinestyle.
You can see my style of shooting through these two vids:

http://www.pinkbike.com/video/348919/

For lenses I run a Canon 70-200mm f/2.8 non-IS, a Tokina 11-16mm f/2.8, an SMC Takumar 50mm f/1.4, and a Super Takumar 28mm f/3.5.

My budget is a little under 4000$, but I'd rather spend closer to 2500-3500 as then I can get the camera before summer and most of my gigs this year.

Let's run through the options:

Sell my 70-200 and 11-16, and buy a GH4 with a nikon speedbooster. Switch those lenses for their Nikon mount equivalents ( if you have any suggestions, other wise Tokina 11-16 Nikon, and Tamron 70-200 nikon)

Keep my lenses, get an FS100 used with an EF Speedbooster.

Keep my lenses, wait for the A7s, buy an EF to E adapter.

What should I do? I'm leaning towards the GH4 but I love the idea of a future upgrade to an FS700.

By the way, I'm in Canada, so I can sell my lenses for a fair bit more than you USA folks.

Manually-accessed remote locations => GHx

Easily accessible => fs100


Ergonomic practicality notwithstanding, I'd take a GH4 over an fs100 for the 10-bit alone.

Yeah, I would go with a GH4 + Atomos Ninja or Blackmagic Hyperdeck.

10 bit 4:2:2 is a big deal, and recording straight to ProRes is pretty much an ideal work flow. Plus a lot of people get boners over 4K and high frame rates, so it doesn't hurt to have those too.

Switching to Nikon glass is a good call too if you are doing purely video. That way pretty much any camera you need to rent or end up switching to in the future, you already have a set of glass that can easily be used on it.

Honestly, if you're shooting low light a lot, being able to pump up to 1600 or even 3200 ISO is clutch as fuck.


Sent you a PM.

With the A7s it seems as though you could pump it up well past 3200:

Agreed. While all three are great cameras, for low light the a7s looks phenomenal. I also think it depends on your ergonimics preference. I guess we will have to see how the a7s really is.

I'm assuming the A7 and fs100 will both have similar capabilities seeing as they are both sony, similar sensors, etc. (theyre different sizes but same tech)

The A7s is beautiful lowlight that is IMO better than the FS100.

However, that rolling shutter test was terrifiying.

aside from getting a camera solely for low light, is the a7 the next "best" DSLR to upgrade to?

Buying a camera based on its low light capabilities is like buying a car based on how well it drives while ramming against the guard rails.

for me the advantages of the a7s would be, low light, full frame. Gh4 would be, 4k, and lower price. If wide angle work is important to you the gh4 will suffer as it is 4/3 sensor crop.
