Thank you for posting and great shot. It is great that focus can be adjusted in such small increments using the Bluetooth remote. Have you tried to focus stack landscape shots? I assume that you would need a lot of button pushes to move the focus point enough for a landscape stack.

Thanks, I'm not sure it would take too many shots for a landscape but that would really depend on the range of focus required.

One nice thing about this method is you could set up exposure bracketing on the camera and then end up with both exposure and focus bracketing after shooting multiple shots with the focus bracketing.

Can I ask how you came up with 3 button pushes between shots? Are you varying the number of button pushes for different subjects depending on how close you are to them?

I did some empirical testing and was able to determine that the button pushes were tied to the depth of field of the lens at the chosen aperture. In my testing I found that by using 3 clicks I was not loosing detail between focus points. Surely you can't go wrong with 1 or 2 but it would require many more shots to achieve the desired depth of field.

I'd love to hear results other people find.

MikeEvangelist, I thought you were my savior by your finding that manual focus needed to be selected in the menus, not on the lens or via quick switch buttons on the camera body. However, when I tried to do so in the menus, manual focus seemed to be selected but grayed out, and I got a dialog box that said I had to make this change on my lens AF-MF switch. I have a Sony 24-105 that has that switch on lens, and it turns out that it is the only lens I have for this camera. I bought the RMT-P1BT just to use the focus feature for stacking, and it simply does nothing. I've tested it several times and while the shutter switch works, and the - and + buttons light up the red light on the remote, suggesting communications with the camera, the focus does not change. ANY IDEAS?

I have my C2 button set to toggle MF and if I turn on MF with that my 90mm works fine. I also has success with the 135 GM.

That worked!

I really, really appreciate your interest and effort to figure this out for me. Thank you sincerely.

I think I’m going to pick one of these up for macro. Thanks for sharing.

I bought one of these and must be doing something wrong. Every time I try to turn on the blue tooth remote menu item (after turning on bluetooth), I get a message saying "perform Pairing on the connected device"

Device Name ILCE-7RM3

The Cancel button is highlighted and to the lower right it says Enter.

Bottom line is I can't get the menu system to turn on the blue tooth remote. What am I missing? It's probably something trivial but nonetheless I'm not getting it to work.

Thanks for any suggestions.

I assume you are on firmware 3.0 or 3.01. Once paired, the remote has reconnected whenever I’ve powered the camera back on.

Yes on the firmware, but I can't get it to connect the first time. It won't allow me to turn on the bluetooth remote feature. I keep getting the message I posted above.

Never mind... I figured it out. The instructions were a little vague on what the pairing screen looks like.

Has anyone tried the focusing + and - buttons on a non-native lens? For example, I used an MC-11 and an older Canon 100mm macro (non L, non-IS, ultrasonic focus - yup, an oldie but VERY sharp) but the buttons did not work. I hate spending the money on the 90mm Sony with such sharp glass as the Canon, but the Canon is useless for focus stacking at this point unless I do it manually.

I tried setting my af/mf toggle to the AF on button, and my AF on button to the C1 button, and that seemed to work

Just got mine and was trying it out at home.

Was surprised how much smaller it is than what I was expecting. Was smaller and less cumbersome than my previous cheap-o wired controller from Amazon.

I have a question. How do I turn it off?

I basically put it back in my bag once I turned the BT in camera off but how do I turn it off not to waste battery. Would be terrible to depend on it in the field only for the battery to be dead.

Thanks.

There are a lot of used returns of this remote at Amazon, Adorama, and B&H. I just ordered one for about $50 to experiment with.

If you find out that it would be easy to modify the software, let me know. Would love to make the stacking automatic, instead of needing to hit the focus button three times for each item in the bracket. Maybe we need to create a robot finger that is programmed to do the pushing

Does Sony still own a fraction of Olympus? If so, I sure wish they would get permission to include auto focus bracketing in the camera!

I just noticed this comment on YouTube regarding using the focus buttons with this remote. Can anyone confirm this?

"I've purchased this remote in the hope that I'd be able to focus stack without touching the camera. Unfortunately this isn't the case with the Zeiss 16-35mm F4. Focus shifts from 1m to infinity with a single tap of the plus button. Occasionally it will go to 9m, but this will take multiple attempts (going back and forth in the hope of it responding with greater granularity). In stark contrast the 85mm 1.8FE takes an eternity to get from 1m to infinity - with a press being required for every meter up to about 50m. I'm hoping for a firmware update from Sony that will make manual focus control more usable. It's a real shame as the remotes key features simply doesn't seem to work properly with some lenses."

I've had this remote since it came out (I pre-ordered it) for the sole purpose of taking portraits, either self/family or of others. For that purpose, it's perfect. It gives me the ability to mount the camera on a tripod and direct/pose freely without being tied to the camera.

I love the fact that pressing the shutter button enables Eye-AF. That's huge for me. I don't always shoot portraits this way, but when I do, it's very liberating. I love that the remote is small and light, and is Bluetooth. Overall, I think the integration with the Sony camera is seamless.

I can't speak to its use outside of what I described, but for portraits in which you can setup a tripod, I highly recommend.

if sony's done one thing right, it's this remote. Instant trouble free bluetooth connection, doubles as a tally light for video recording. I wish they could have made with a switch for multiple connections, sometimes I use another body, which cant use the remote, and it's bothersome not having said remote.
