Thank you for the great advice!!
I do have a question, about using the ipod/iphone....that adapter from kvconnection...looks like it would plug into the iPhone where the earphones go, I don't think that plug also adapts to a microphone..??
I was wondering if you meant to put some kind of link on there for a iPod/Iphone dock connector to mic adapter? Is there such a thing? I've not come across it yet with my searches.
I saw the Blue Fire app. and they appear to want you to pair it with their iPhone/iPod mic, which is just a normal style mike and I didn't see a lavalier option on the "mikey" they sell....
But these are great ideas and wondered if you had a little more info on that lavalier to iPhone/iPod adapter...which looks to require some type of dock to mic adapter...
The pinout on the iPhone headphone jack has an extra connection for the microphone; that is one of the reasons you need an adapter. That is why you see iPhone headsets that have a built in mic for talking on the phone with the earbuds in. The adapter from KVConnection uses only the microphone input on the headphone jack. They also make adapters that add a headphone jack, so you don't have to unplug the adapter to listen to the recording, as well as adapters with a standard professional microphone input (XLR)http://www.kvconnection.com/product-p/km-iphone-43f35f.htmhttp://www.kvconnection.com/product-p/km-iphone-xtrs.htm
There are options that use the dock connector, but they are generally more expensive and bulky, with most being in the $100-$200 range. I've never used any of them, but here is an examplehttp://www.amazon.com/gp/product/B005DNAB12/ref=pd_lpo_k2_dp_sr_2?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0064RMV9G&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1JRCQQZT5TV1ZWMS5X4A
Blue fire works fine with any microphone. It can even use the built in microphone of the iPhone. There are other apps as well, but I found Blue FiRe to be the best free option.
I have made several videos using this method. It's especially useful when I make videos with my 50D, as that camera doesn't have any audio capabilities. I just grab the lav, my iPhone, and the adapter and I'm set.
