Hello,

 

I just got a a7s ii . Prior to getting the Camera, I got the Comix adapter, (the cheap one) so that I can use my Sigma 28-70 to work on the camera...

 

The Lens works, I can shoot... But I CANNOT, control the aperture . It cannot read the aperture.. 

 

This is the lens

I dont really care for any "auto focus stuff" I just want to be able to control the aperture as normal.  The cheapest solution is what im looking for.

 

Thanks

That lens appears to have no iris control ring. 

  

There are adapters, cheap but about $20 more 

than the very cheap ones, that have a lever to 

control the iris. You don't get an f/stop scale but 

usually there's a numbered scale from 1 to 8, to  

let you set any specific number of stops away

from wide open [or set wide open, too].   

   

Such iris control adapters move the mechanical 

iris actuator lever just inboard of the lens flange. 

Hopefully your lens has such a lever. I just this

minute checked a modern Nikkor 18-200 which 

lacks any iris ring, and find it still uses the same

old iris actuator lever as Nikon used in 1960 :-)

      Welcome to the FORUM. I'm not familiar with that camera, but I use manual-focus lenses on my Sony DSLR all the time without any problem.  The difference between your camera and mine, is that yours has an electronic viewfinder.  You can get a user manual on-line at Sony's website.  That might explain what type of setting you have to make to brighten up the EVF. In any event, others who use that camera will jump in soon with an explanation.  Despite that, you should download the user manual.  It will take about a week to read and digest it all.  The Sony manuals are good at explaining how to set each feature individually.  What takes longer to grasp is how to use the various features in combination.  This gives the camera a lot more power, but can get pretty complicated at times.  You'll find out what I mean. There are undoubtedly some good books about your specific camera that go into more detail than the Sony User Manual. Happy shooting.

      Sounds like a Live View setting This link will take you to an online searchable manual. Help Guide | Top Have you done a factory reset yet? Always do a factory reset when you buy a used camera, there's no way to tell what oddball settings the old owner put it. You want to start from scratch. Also, check the firmware version and update it if needed.

      Hello All,    Steve here, long time photographer but brand new to this forum and new to Sony a7Rii. I have worked with everything from 35mm, medium format, large format up to including ULF cameras. I purchased the Sony with the hope that I would be able to use my vintage Nikon lenses in a digital format. I have a Novaflex adapter on the camera which fits nicely and works and obviously needs to be stopped down for exposure. What I am finding is that when I go outside in bright light the viewfinder/screen becomes rather dark even with the lens wide open. Works just fine indoors but "grays out" when outdoors. This camera is new to me and did not come with an instruction manual. Any thoughts? Thanks, Steve
