I've been out today experimenting with the pano mode on the A77. What is the secret to getting complete 360 degree pano's in one take? I have it on wide mode but with the CZ 24-70 I am not able to get more than about 150 degree shot. I don't want to stitch in PS if I can do this in one take in camera.

360 degree pano with A77?

you cant do that on camera , not eaven with 8mm. is much better if u shoot 20 separate photos and let microsoft ice to stitch the images for you . Is very simple and much more correct than in camera panorama .

You can't, you'll have to do it yourself in PP.

I have had some success with the Samyang fisheye. Overall, I prefer to do the stitching myself with Hugin.
Thanks for the quick responses. The project I'm working on involves getting pano's of about 87 2 acre lots in a planned development. So each lot is shot individually as it's own pano project. To shoot each of these and then have to do a stitch up for each is a massive amount of work + time. Thought maybe the A77 could cut some of that time down in camera.
I guess I'll look at other options...

Hi,
other than shooting the panos with some overlapping of the individual images with some care at levelling the cam (or using a tripod) the stitiching itself in Microsoft's ICE doesn't require a significant amount of time. Normally it doesn't take more than some seconds for ICE to load the images and stitch them automatically. However for a full 360 degree pano based on 24MP individual shots your machine should have enough RAM. Most probably the width will surpass the critical mark of 30,000 px which still is the limit for JPG files so I'd recommend to export the stitched pano in TIFF format - which is going to be huge (my guess over 1GB) so don't worry when reading from and writing to HD takes some time.

Does it need to be a stills pano? What about a video 360 degree turn?

Perhaps take 2 180 degree (+ overlap) panos with the camera, then stitch the resulting two files together.

Just use a tripod and make sure everything is level.
I agree with this too. ICE is pretty good.
I did once hear that with a wide (10mm) lens on an APS-C sensor was wide enough that the in-camera pano would do a full 360, but I never tried it.

The traditional pano composed of 10-15 individual images is just not gonna work for this project. We're talking about 87 separate pano's consisting of 10-15 shots each. I would have to manually write down the image numbers for each 87 to track shots to each physical lot number and then hope I don't get out of sequence. One image off and everything would fail. Just not practical. So I will look at the video option though I do not own a really smooth pan head so that is going to be marginal.

Not true. I've managed a full 360 degree pano with my Samyang 8mm on my A77 in the vertical orientation.
Virtual 360deg spherical interior marketing shots are typically done as 4 still exposures (maybe with brackets for blend/tone-map) with an 8mm lens on an FF body. Camera is in portrait orientation. Calibrated pano-head would be used.
Here are some techniques explained (using Sony):
For APS-C full 360 spherical, including zenith (above) and nadir (below), you need 6 shots on an 8mm lens - explained from around 02:45 in the video above.
I do not know about the A77 in-camera stitching software for an 8mm shot without zenith and nadir and stitching the two ends, but I would think you can sweep most of your horizontal field-of-view OK. You won't get a 360 spherical though, but I am not sure you actually 100% need spherical for your project if each is just level plot of land and zenith and nadir will not matter, but that also depends on how and in what application you want the images viewed and navigated.
If in-camera stitching cannot do it, you need stitch with software like Hugin, PTGui, or other, and then to navigate a true 360 spherical pano, you need encode it to format others can use (like QT).
If you want to understand the full processing techniques, watch the rest of the above video sequence:
.
If you do not have access to an 8mm, then you cannot do it as efficiently, and will be stitching more shots. 24mm on APS-C is probably not the way to do this kind of project for the reasons you have explained yourself.
Your other choice for efficient 360deg panos might be to use Android 4.3 smartphone and Google Photo Sphere. I only know that exists and am not familiar with it though.
