I think the A7R AF is super accurate.

I say this as a previous owner of the 5D2 and 5D3.

As mystik610 has alluded - this is due to the A7R's use of contrast detect AF; it's rarely that fast, but it is accurate. Phase detection can/should be much faster, but can be less accurate (hence the existence of AFMA [autofocus micro adjustment] on some DSLR bodies). In theory, a DSLR focussing using LiveView should be just as accurate, but slower (as it'll also be using contrast AF).

There are exceptions - such as the 70D with its dual pixel phase AF system in LiveView. It's faster than contrast detect, and shouldn't suffer from the usual phase problems where the AF sensor is separate to the image sensor.


Camera, some lenses, too little time, too little talent

^Nice; really like those clouds. I do wish the verticals were corrected, though. :)

Thanks x-tan and David. That was shot using the Sony 24-70 @ 35mm. Here's one more at 38mm.

I just found out that the blinkers (highlight warnings) are broken on the A7 and A7R. Another thing that needs a firmware fix. :)

Quote:

Blinkers provide feedback that portions of the image are blown out and have no highlight details. When this happens you’ll notice that the histogram will touch the right side. However on the Sony A7r the camera will display blinkers, but when you look at the histogram its not touching the right side of the graph. There is a noticeable gap between the right end of the graph and the actual data in the histogram. So to determine that the camera is basically lying to us, we took that same image into Lightroom 5 to see where the histogram falls and to see if the highlight warnings show. Low and behold, the A7r histogram is correct and the A7r blinkers were wrong.

From what we gathered the image being displayed in the back of camera review is processed JPG from the Picture Style. The blinkers are based off the JPG while the histogram is reading off the RAW.

After figuring out what was going on, Charles and I don’t like this at all. This legacy functionality that we have been using is now broken! It no longer represents what it has in the years of digital photography. So do we accept this and adjust our train of thought when it comes to the highlight blinkers on the Sony A7r?

is there anyway to configure the A7 so use the Viewfinder only, but when I'm accessing the Menu or looking at the pictures it uses the Monitor?

it annoys me how if I select the VF, then I have to do everything through it.
it makes changing ISO or reviewing pictures a PITA.

I'm pretty sure all bodies do this though - blink highlights according to the jpg processed as per the picture style selected (even if you are shooting raw only, as the raw contains a thumbnail jpg)

I am seeing a number of So Cal CL ads for A7/(r) cameras listed as factory sealed BNIB. To me this is unexpected for such a new camera model. Is this phenomenon peculiar to So Cal or are others seeing is too?
Thanks

My way:

Menu -> Custom Settings -> 6 -> Custom Key Settings -> Custom Button 3 ("The Rubbish Bin"; You CAN choice any of C1, C2 or C3) -> Deactivate Monitor.

Have fun :-)
