Here's a look at two iPhone mic adapter cables I purchased on e-bay. Both work fine. I tested them with one of my Giant Squid mics.

I look at another travel tripod option shipped to me direct from China. So for $138 you can buy direct and get a really compact tripod that IMO is a pretty good value. This tripod comes apart and you can also use it as a monopod.

I look at three affordable cables that are used to hook a Shure SM57 or SM58 to the red mic input (1/8th inch aka 3.5mm) of Sony cameras like the A7r, NEX07 or VG10. I'm sure they will work with other mic/camera combinations. Please share your adapters and other cables used to connect mics to video cameras.

GLS Audio 6ft Cable 1/8" TRS Stereo to XLR Female - 6' Cables
YCS Basics 10 foot xlr female to 3.5mm stereo male cable
What is the best way to get XLR Audio from a mic like a Shure SM57 Into a 3.5mm (1/8th") mini mic Input jack on a camera like a Sony NEX-7 or A7r or other Nikon or Canon DSLR? Is an adapter cable the answer? Should I carry another piece of kit like a Zoom H1 or H4n or a simple interface box like a Beachtek DXA-2T or something with a pre-amp like a JuicedLink RM202 Riggy-Micro Dual-XLR Preamplifier?
PS: I use and like Mogami mic cables. Would this adapter do the trick:

By the way my Giant Squid lav mics work great just plugged direct into the cameras.
Let me know your thoughts.
