Thanks for those responses. I see what you mean and I do still have Sony HDR SR12e camcorder. I'm assuming the G6 video quality will be noticeably better than my Sony?
Not necessarily. Most cameras can do fine under optimum conditions. It's when they're pushed under less than optimum conditions that you may see a difference. So, instead of buying a new camera, another way to go is to spend the money on equipment (e.g. lights) that will help to create optimum conditions.
One caveat: the SR12e only does 60i, so a keen eye may notice a subtle difference between that footage vs footage shot at 24p (on the G6). The SR12e also maxes out at a lower bit rate, so a keen eye may be able to notice a difference here, too. But again, another way to approach this is to spend your money on other equipment so the CODEC won't be pushed as hard.
BTW the SR12e also captures 10 MP stills/photos.
I was hoping to upgrade my point and shoot Canon at some point anyway so if it fails to perform at a good level on video, I'm sure it will do a very good job at taking pics anyway?
Again, not necessarily. And be sure, again, to take your intended delivery/display method into consideration. e.g. most folks would have a very hard time telling the difference between a photo of a family posing in front of the Grand Canyon in broad daylight when posted on Instagram that was taken with an iPhone 4 vs the same shot taken with a Canon 5D.
I'm also thinking it could be used for a second camera if it becomes impractical to use for the main shot (we sometimes use an additional side camera when recording speeches for a side shot of the speaker or panning on the audience). In that case I would buy a semi-pro video camera for the main camera, something like this http://www.youtube.com/watch?v=T7hHxDh5OcM
(interesting video that compares it with the GH3).
First, you may find this old forum thread on "Formulating DSLR gear from scratch"
Second, note that the AC90 has a tiny sensor which results in really deep DoF. Now, as I noted in my immidiately preceding post, this may not be a bad thing, but be aware that you will be stuck with this. Whereas, you would have other creative options with the G6 (or an AF100 or VG30, for example).
I can't justify spending more on the GH3 for ... the unlimited continuous recording (that's for my purposes).
Where did you hear/read that EU GH3s are not limited to 30 minute takes like all other EU hybrid photo/video cameras? I ask because I've heard the exact opposite.
hionhifi, like your point about low light as most shooting will be indoors (a lot in the evening indoors too).
As I said previously, a better way to approach this issue is to buy some lights. I say "better" because aperture also affects DoF, so without lights, you are allowing a technical limitation to affect creative choices. Yes, there are circumstances (run-and-gun, ENG, events) when setting up lights is not feasible/practical, but the corollary is that these circumstances are not well suited to a hybrid/photo video camera. It's always preferable to use the appropriate tool for the job.
the 14-140mm lens is a lot cheaper if bought as a package http://www.currys.co.uk/gbuk/cameras/di ... 1-pdt.html
Yes, but do note that the price listed there is still 60% more than the £550 figure you initially mentioned. And that was my primary point: make sure you're doing an apples to apples comparison. e.g. instead of comparing the SR12e's 12X zoom to a G6 + 14-42mm (3X), a closer comparison would be the SR12e's 12X zoom to the G6 + 14-140mm (10X).
Again, make sure you're doing an apples to apples comparison. i.e. what if you want to zoom from 30mm to 60mm? You can't with those two lenses.
Oh and any thoughts on how to do a live podcast/broadcast with the G6? - Help appreciated.
Yes, don't. As I said above, it's always preferable to use the appropriate tool for the job. For streaming over the web, that tool would be a webcam. No need to reinvent the wheel. It'll likely cost you more both monetarily and time-wise, and you may even get poorer results.
P.S. if you're interested in what I use, I posted a list of my camera gear
a while back. In addition to that, I have three sets of ND filters (so I don't have to let light levels affect the aperture I use) and I use a TASCAM DR100 Mark II and Zoom H4n to capture audio.
