There's been plenty of discussion and audio tests with the Rode VideoMic vs. the Rode VideoMic 'Pro', so here i'm just showing the size difference between what I would normally be carrying around to the new smaller form factor of the Rode VideoMic Pro - Compact Shotgun Microphone. Huge difference in size, weight, and build quality make it all worth the price difference. I'm not sure where I put my OEM Foam cover for the regular VideoMic, so i'm showing my Aftermarket MiCover Dead Cat.
Sure there's a bit of a price difference, but at least you get a FREE Rode Dead Cat with the new Rode VideoMic Pro (with online registration) shaving the difference down another $40.00 dollars. Otherwise with the normal VideoMic you would need to purchase this optional Dead Cat: https://www.bhphotovideo.com/c/product/392861-REG/Rode_DEAD_CAT_Dead_Cat_Wind_Muff.html/. The build on the shock mount is a nice touch over the other design in the lower end VideoMic. Aside from design, the switches are much more accessible (finally usable) and comes with the new +20db feature which should work well with DSLR's that have manual audio level controls.
