I'm in the same boat as you, HMC150, and I'm no expert.
Because with DOF we're adding another lens, the image is going to be flipped upside down. For many cameras, this makes shooting difficult because the image on the LCD monitor is upside down, making framing, pans, etc. difficult. The HMC150, bless it, has an option to flip the LCD. This function can be linked to an easily accessible button. Now we can frame and pan naturally. Granting all that, it would seem the Brevis no-flip is the way to go.
However, the footage is still upside down! We need to know how to flip the video footage. Does this take special software? Does it take a lot of time and/or computer resources? Can this be part of a usual transcoding workflow?
If it is a pain to flip, then a flip Brevis would be the way to go. AVCHD footage doesn't need a lot of additional challenges.
But if it is not a pain, then the no-flip is the ticket.
Let's search the Internet.

User stev warns:
my problem is... if i render a flip-corrected footage and import it into premiere...and then make a slowmotion and render it...
it is not as smooth as
if i use the captured footage ("unflipped"), rotate it, make a slowmotion and render it
in other words....the flip and rendering process destroys something.
Uh oh. But what software is he using to flip? We don't know. We also don't know how bad the flipped footage is. As for slow motion, we don't know whether he's merely slowing the footage down, or doing effects processing in Adobe Premiere. If it's the latter, the problem may not occur in other software. If it's the former, you and I may have a problem, too.

Raylight MXFX can flip the image.
Check this info on how to do it: http://dvfilm.com/MXFX/help.htm
720p DVCProHD footage can be flipped without any quality loss (no decoding/encoding required). 1080p needs recompression, so the quality will suffer.
As HMC150 owners, we'd have to transcode from AVCHD to DVCProHD, then do the flip. And, apparently, we'd lose quality on 1080p (24p, 30p), which are my favorite options.
AVCHD is not supported, but DVCPROHD is. It's about $100.
As for workflow, trez continues:
The simplest option is to get used to working with flipped footage in FCP. If you make the flop one of your favorite filters, you can easily flip multiple clips - just select them on the timeline and choose your favorite filter. Great thing about favorites is that they remember the exact settings of the filter, so you don't have to change the flipping axis to 'both' for each clip (the flop filter defaults to 'horizontal' afair). The only drawback of this method is that the footage is displayed unflipped when triming the transition or cut.
The workaround is to apply the flip to the clips in your browser window, but I haven't been able to figure out how to do it for multiple clips in one pass. If you assign the keyboard shortcut to your favorite filter, it can be done one by one quite quickly, though.
User Noah Kadner replies:
If you're going to transcode- transcode to ProRes- much higher image quality than DVCPROHD.
Does flipping software support ProRes? I assume these flipping functions are either built into the editing suites or plugins that function from them. If an editing suite can read ProRes, it should be able to flip it. (?)
If you're using Eidus editing suite, you click on the little mirror icon to flip the image. Sounds easy!
Flipping the image in Sony Vegas. It involves numbers and minus signs. A little more complicated the first time around.

More Sony Vegas. Adam posted a free image flip plugin. But Is something lost?

I tried Adam Wilts Flip and compared it to shooting same scene with my FX1 upside down. Seems to loose something and appear grainier in the flip. Does that reflect what you seen ?
My conclusion is that either flipping footage is so easy and of such high quality that nobody bothers to post their workflow except nitpicks, or flipping footage is such a pain and results in such low quality that nobody bothers to use a non-flip 35mm adapter. I only wish I knew which was the case!
