C1, then move left right with the wheel. Closest thing you can do to bbaf is to use the AF-on to disable/enable AF. AF isnt pretty on this camera, probably better off with center focus and recompose.

Thanks Charlie, got it working with the centre button on the rear dial now. I had thought the sony 55 lens was quick to AF? (Not got one yet)

AF is instant especially when you turn on your AF assist. Except for a really no contrast target.

i have my AF/MF button set to AF ON so i can lock focus and metering. Very useful for brenizer effect and pano. That's how i do it with my former 5D Mark III.

Agree with Vinz. The zeiss 55mm is fast. Boy is it sharp too!

I'm tempted by the 55 but I'm more a 35/85 kinda guy so worried about making the purchase, however I'm at the point now with the fuji that if there's a better option that is compact size I'll be selling it on (issues with the way lightroom handles fuji raws and also the IQ is not quite there for me).

I know I can use canon glass on the sony and manual focus with peaking but not sure how realistic that would be to achieve at fast apertures with a quick moving kid

Xpfloyd, search YouTube for "sony a7 menus explained" by Sony Alpha Labs (Jay). He does a good job walking through the menu system.

On #2, I also have that question. I believe it is in the center button of the dial wheel.

This from Colby Brown had some good tips on accessories and a good review on the a7r for landscape shooters.

Im the same as you. I love 35 over 55 but the 55 is so good i picked it up to compliment my sigma 35 art and have native AF.

I recently picked up a Sony A7R. I must say I am very impressed with the 35mm 2.8 Zeiss. It is as sharp as the Sigma 35mm Art, and seems to produce better boken and contrast, making it a top tier 35mm lenses. It is the ideal size for this cameras body.
However I'm certainly not bothering with the 55mm, I've never liked the 50mm focal length. For every situation it seems to be either too long or too short.

I've seen a lot of shots from the A7R at ISO 100. I'm about to purchase an A7R and was hoping someone could clarify this for me...they say the "native ISO" for the A7R is 200. Doesn't that mean that's what the manufacturer recommends for best IQ? If so, why would you use 100 instead of 200?

Sorry for the beginner question.

who says it's 200? that's odd considering 100-6400 being default auto iso range. Usually, default range is non boosted. If native is 200, then 100 is boosted plus one EV and pulled down.

Several of the written reviews and youtube reviews I've read/ watched. I could easily be totally wrong, but everything I've seen so far said the native ISO is 200. I'll try to find specifics.

These guy's review is the first that came to mind...right around 5:55 in the video if you want to skip ahead.

Hmmm...but in Gary Friedman's e-book he says, "The short answer is that this CMOS sensor actually has a native speed of ISO 100". So maybe the sources I've seen quoting 200 are wrong.

Thanks everyone for the help. I think I'm going to give the FE 55 a go.

(Anyone want to buy a lightly used fuji kit? :) )
