| I thought an EVF should be showing you exactly whatever is hitting (and will be captured by) the sensor. If a lens casts only a part of its image onto the sensor, that's what you should see in the EVF. That's why, in addition to previewing the exposure, they have some advantage over the older style OVF, which could not show the exact framing. |

The a7 cameras have an automatic mode that adjusts to crop-sensor lenses by cropping ON the sensor and showing the cropped image in the viewfinder. I understand Neil's question to be about whether the cropped image is displayed at the full resolution of the viewfinder, or whether the already small viewfinder also has some of its pixels cropped off, making it grainier than it is at full frame. And I don't know the answer.
There IS, of course, an option to turn off the auto-crop, in which case you'd see the full effect of the vignetting, but the image would be quite small in the finder... |

Could someone please explain the difference between all the models:
A7
A7s
A7r
A7II |

Pretty much sensor size. The A7R has a huge 36m or something sensor and no AA filter, similar to the Nikon D800e. more geared towards landscapes perhaps. The A7S is at the other end, still Full Frame but only a 12m sensor, which sounds small these days but it has been designed for amazing low light, high ISO, to an amazing level. It also has very high end video capabilities. The cheaper A7 is kind of inbetween, with a 24m sensor. It also has a slightly lesser build quality. What Sony has done has come out with three cameras designed for different uses. I wouldn't want to use a A7R for a wedding, that big sensor effects lots of things. The A7S would be perfect for a wedding though. |

All have full-frame sensors, so they are all the same size in that regard. What's different is the type, and number, of photoreceptors ON the sensors as described by Rooum in the previous quote. In practical terms, the a7r is a VERY high-definition, extremely detailed sensor. It doesn't perform as well in the lower-light situations at higher ISO ratings. The a7 is middle of the road in that regard. The a7s is a new idea, geared towards stunning video performance and outrageously good low-light adaptability. The a7ii is yet to reach the market, but they are taking orders; like the a7, it combines "standard" autofocus with "phase-detection" autofocus, which the a7r does not. It's an evolution of the a7 that includes a 5-axis, in-camera image stabilization system. |

Say, in which five dimensions are those axes oriented? |

"The innovative 5-axis image stabilization on the new α7II detects and corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) that tends to occur with a telephoto lens, shift shake (X and Y axes) which becomes noticeable as magnification increases, and rotational shake (roll) that often affects shots at night or when recording video. The 24.3 MP full frame sensor moves to accommodate all of these types of shake, with stabilization equivalent to up to 4.5 steps faster shutter speed of correction2." |

Thanks for that. I had read all of page 1 and page 3. Should have read page 2 ;)

It seems that rather than explain degrees of freedom, the marketing group at Sony has decided to redefine the term "axis". |

Indeed, I was hoping that one axis would be time .... |

They're not the first ones. Canon played a bit fast and loose with the term as well when they introduced the 100mm IS Macro...

Congratulations on your new baby and how fun that is, it is always exciting to see new toys.
I tried them out in the stores too and the stabilization they have for that camera is just crazy and insane
but after searching the lenses I would need and want for it, it was just out of budget for me.. maybe when I win the lotto.
Wish you all the fun!

Well, I sold a lot of redundant gear and am the proud new owner of the latest and greatest from Sony.
Not yet had time to use it, but let's just say, I'm excited.
I opted for the A7s II over the A7r II as I'm more interested in having something with low light capabilities. I still have the D800 and won't get rid of that in the near future.

Congrats on your new stunning gear. I prefer A7RII (I guess it's the perfect camera now) but still you got a superb photo/videocamera! |
