1. How often do sales occur with Canon? Right now I can get a MK III for 2800 (body only) do you think that will go down in the next month or so? worth waiting or just buy now and be happy?
They go on sale pretty often. Sometime more often than others so it must depend on inventory and launches. You can count on at least 3-4 times a year but probably every other month. You could save 15%-25% on the 5D2 & MAYBE 15-20% on the 5D3 (they don't always put it on sale). Is the 300-500 bucs worth waiting for? Of course the answer to that is totally dependent on your patience & need. Me, I always try to pay less for tech that depreciates fairly quickly with time.
2. I've read a little on CLP but there wasn't a great single post/article I could find as I do not understrand it. I do not have a P&S I just have the 60D (seems like I could get 500-650 for it which would be better than the CLP unless I misunderstand)
DONT CLP your 60D! Do what one of the posters recommended: pick up an old, well used or broken Canon (you can find them at yard sales, craigslist, ebay, etc.) and use that.
Reference selling your 60D-if you're not good at moving things online, try posting a notice on your local camera club website or at their meeting, etc. Fyi I sell all my old equipment online thru e-bay or amazon. You take a hit on their commision but its much easier, & probably safer, than craigslist.
4. Any good articles/videos on creating a low-budget setup for doing run-gun etc. documentary work... I already have:
for audio... do I need wireless mic? lavaliere?
I can't give any input on video other than since it seems to be a crucial reason for your purchase, you need to give the extra $$ for the 5D3 serious consideration. My friends that use Canon for their video, all sold their 2's & bought 3's within 6 months of 5D3 launch. None of them regret it.
My only 2 real suggestions on video are:
1. Download & use magic lantern once you make your purchase and get familiar with your camera. If you aren't already using it on your 60D, you're going to find it very helpful once you get used to it. I like using it for stills & it's really designed for videography. I imagine you'll wonder how you got by w/o it.
2. Condsider getting a battery grip. If you can handle the size, its makes handling & shooting much easier. But it definately adds to the weight & size so test it out with your favorites lens attached and see if you like it.
Most of my video fiend friends also use stablizers, rollers? (looks like a skateboard), special lighting, etc. And they ALL use very good mikes. I can't help on any of that. But they tell me that the camera itself isn't even half the cost of their set up. & when they say "set up" they are not counting all the lens they own. Just their 1-2 main prime lens (they mostly seem to prefer prime lens for video) plus the rest of their video equipment...
Last post for me so good luck on your documentaries. Take care, sk
