Multiply by ten

A week and change later, I find myself on an airplane again. Hello from 34,000 feet!

Last time I typed, it was about moving away from the A-mount and making an investment in the E-mount. I decided to trade a whole bunch of A-mount stuff for a smaller amount of E-mount stuff on the A7s body.

I arrived at my house last Friday night, late, after flying home from Minneapolis and then picking up my equipment at a friend’s house. I had it shipped to his office as my typical delivery people are less than vigilant about requiring signatures. I drove back to my house quickly and unboxed everything.  My first surprise: The A7s package came with two batteries.      : )

And I could not get the batteries to charge fast enough. I got one battery to about 25%, dialed in my typical settings, and took my first shot. Here is the first jpeg from the RAW+JPEG combo.

ILCE-A7S, FE 55mm f/1.8 ZA  @ f/1.8, ISO 102400, 1/60s

The room was not nearly that bright. Here is a crop of my first swing at it in LR and the NIK Suite.


I put the RAW file through NIK DFine, with default settings, and dropped the exposure a stop and a half, and the shot is still brighter than the room. So I need to figure that stuff out, clearly. But ISO 102400!! The ISO speed in the default Windows 8.1 properties maxes out at 65535.


This tells me no one thought it could go higher. It also tells me there is another EXIF attribute ISO is stored in as Lightroom sees 102400. I think it is “Recommended Exposure Index” If you’re curious, this is what the unedited RAW looks like.


Also keep in mind, the 55mm f/1.8 Zeiss is wide open here.

I only shot two shots the first night. I let the batteries charge and fired a few more the next day. I set Auto ISO to 100-102400 and just let it ride. Here is one of the more impressive shots.

ILCE-A7S, FE 70-200 f/4 G OSS @ 177mm f/5, ISO 5000, 1/200s

You read it correctly. ISO 5000. Five thousand. Here is a closer look, unedited.


I’d say there’s a lot of detail in the ISO 5000 shot. All I did here is remove a little bit of white and brightness.


Again. Five Thousand. Here is a full-size unedited crop of a shot from my A99 at ISO 500.

SLT-A99V, 50mm f/1.4 SSM ZA @ f.4, ISO 500, 1/200s

So it appears ISO 5000 on the A7s has less noise than ISO 500 on the A99. I have more testing and shooting to do. But the preliminary results are promising. And I am not used to the balance yet and have yet to explore all of the new features.

ILCE-A7s, FE 70-200 f/4 OSS G @ 200mm f/5, ISO 1000, 1/250s

So far, I like the manual focus zoom feature the most. When you go to manual focus or use DMF, and spin the focus ring, your specified focus point is magnified 10x in the EVF. I still need to get a feel for it. There are a couple things I miss. I don’t think I am getting a geo tag anymore. And the LCD doesn’t oscillate like the A99. It is always exposed. I need to buy a cover for it. Finally, I am having a hard time getting used to using zoom lenses. I may have to force myself to use the zooms.

I’m being asked to put my tray table up. I guess this is a good stopping point. Have a good weekend!
