A7i - A7Sii - A7Riii

I'm starting a new job & career that focuses on marine biology. I would require to do a lot of photography & video underwater.

*This is to start next summer.

 

Before I start that, I will be working at a scuba shop shooting (mainly) photos and videos for clients as souvenirs.

The underwater housing is for the mk.ii models ONLY.

 

The 7Sii is great for my videos.

The 7Rii is good for the stills. Maybe a bit excessive actually. (And getting pricey)

 

What about the A7ii? I hear nothing about this.

-How does the video mode compare to the A7Sii? (I do not require 4K)

-How does the photo mode compare to the A7Rii & the A7Sii - even though this is more focused on video?

 

 

In the future, I could probably buy two separate cameras as it will work with one housing.

But now, I am very limited on funds and can afford only one.

    • Yes. The display has its own settings and doesn’t necessarily show an accurate preview. You need to watch the exposure meter. 
    • What is the issue? Live display doesn't accurately display actual output raw photo. It could be under or over-exposed. When focusing, sometimes you do get a glimpse of what your final image will be. (I believe this is because apparently on sony mirrorless, to aid the autofocus system, exposure is temporarely increased, this doesn't impact your actual exposure, its only temporary, therefore my theory is that what Im looking at, is my actual exposure + 1 stop maybe) The preview is shown as well-lit, however once you see the raw file it's way underexposed. After taking the picture, it somehow does increase the exposure and the output is more accurate to what is shown on live view, like if the camera took a screenshot or maybe the JPEG is wrongly labeled as .ARW, or somehow metada gets corrupted, since shows it was shot at the same settings, same ISO, same aperture, same exposure time but one picture is darker than the other. After taking the picture in this mode it loops back as taking the picture darker.

      Why I believe is an issue with the adapter? Changed the lens to the 50 mm f1.8 and same cycle repeats. Changed to the kit lens from sony and it work ok. Any help or theories? I know the simplest way would be, just use another adapter or maybe buy a sony lens but, I mean... there are plenty of people with this adapter, so could be an issue with this particular unit of adapter? I haven't seen something similar to my case on the internet.
    • @husnu I'm wondering if you've noticed this problem returned with firmware ver 3.00? I was remote shooting with the Creators app after upgrading and noticed that touch focus didn't work anymore. But it's not just the Creators App. Touch focus is not working with the a7IV camera body by itself. Touch tracking works. I tried turning Pre-AF on and using the camera in shutter/aperture priority but it still won't touch focus. This problem didn't exist in firmware 1.01. I didn't test in 1.05 as I only updated to 1.05 so I could update to 3.00. But touch to focus worked on the a7IV camera body and in the Imaging Edge app remote shooting with ver 1.01.
