Metabones IV No Autofocus Bug?

I've been using my Sony A7R2 + Metabones IV with Sigma 35A and 50A as well as the Canon 16-35L for 2 months now. It's been working great, until last wedding the camera would not let me autofocus. I checked the switch -it was correctly set to AF, and the Focus Mode was greyed out in the Function Menu.

 

I checked online and there was a quick fix to unmount the lens, hold the button on the metabones adapter, and reattach the lens and it would enable autofocus again.

 

I had to do this about 4-5 times for the rest of the day. Anyone have this problem before and/or a solution to this? Is it firmware issues? I haven't updated it since I bought it from Amazon.

 

Thanks.

It appears that the button on the adapter might be stuck in a permanently ON state. If you are stuck in Advanced mode because of this you will get a focal length display on the LCD when you zoom the lens and you will get a distance readout on the LCD as you turn the focusing ring but you will have no AF.

      Bokeh?

      By Mr. Lips · Posted

      Like Cameratose, I usually go for as much depth of field as I can, but sometimes there is no getting around out of focus areas, such as a closeup of a cactus flower.  I guess, everything else being equal, I might be concerned about a lenses bokeh, but everything else is seldom equal.  At this point in my photography I think I have bigger problems than unattractive bokeh.

      Sony A1 ii Focusing Challenge

      By MDEMM · Posted

      I elected to upgrade from Sony A1 to the A1 ii and am seeing some significant focusing challenges in the little time I've spent with it so far. Less than 10% of photos appear to be in focus when photographing small birds in subject mode birds with seemingly no improvement when subject mode is changed to birds/animals/people. Scenario: Sony A1 ii, 200-600 G lens @ 600mm, F6.3, shutter speed on male cardinal (in-focus mostly) at 1/250 ISO 125 and female cardinal (nothing in focus) at 1/1600 ISO 100; AF-C set with eye supposedly in focus in both shots. Lens has AF on, OSS on, Mode 1. I've tried switching out lenses using 100-400 with and without 1.4X converter and used handheld and used tripod. Photos are at a distance of 20-25 yards. The photos below are within a couple yards of one another. There is seemingly no improvement in AF performance despite the combinations of lens, tripod and focus zones attempted. Birds are stationary. Many of the photos will have everything in the frame seemingly out of focus and some may have the head in focus and rest of body out of focus and immediate area around bird slightly out of focus at F9-F11. I considered that I was cropping too much and had pixel peeping / expectations problem, but some photos are wildly out of focus when supposedly focusing on eye or body. Neither photo below is cropped. Ideas are welcome!

      Bokeh?

      Agreed, but it's ancient thinking. Any modern forum lets you edit whenever. It's simply a setting they could click to turn off. It's one reason I won't post many photos here. After 10 minutes I lose complete control over my own property.
