Thanks.
I don't want a handheld mic on the picture, so that is not an option.
A cheap wired lav was already on my buying list. It can also be use for outdoor interviews, am I right?
Most of the time I won't have someone to boom. I thought I could mount the shotgun on camera, I know that's not the best, but would I loose all the sound quality of it? Could I use a stand support when I can? I wanted a shotgun to select sounds in noisy environments, but also to record ambience sounds like a waterfall, street protest, bird colonies. Are there other type of mics for that? Does a small diaphragm condenser would be better than the shotgun? Something like the LineAudio CM3 or this https://www.amazon.ca/gp/product/B012OHZJ8O/?tag=8013063-20
I had heard that in camera recording, particularly in DSLR's, was very poor quality, that's why I wanted an external recorder. If using a preamp does a good job, that would save me from sync problems!
It might also be good to precise I would like to have good audio, not just a one step better quality than the built in mic (I don't like to buy a lot, I prefer long term investments instead having to upgrade in a year or two).
I don't know a lot about audio gears, but if we make a comparison with cameras, I would like to have something similar in quality as a canon 7d or a BMPCC, and not my nikon d5100.
Does anything I mentioned might change your answer?
Thanks
