GH4 Lens Help

[franklin]

I am working on a side project and looking to pick up a GH4 to get 4k recording. I am out of touch with the compact video cameras and in need of some lens recommendations.

Need to do 2 things. Lots of green screen head shots and some basic self defense demonstrations shot in a workout area. The 4k is perfect for the demonstrations because the final outputs are 1080p so I can crop to close-ups without do multiple takes.

Don't need auto-focus so I am open to anything. For the green screen stuff a fixed focal would be fine and I don't need a fast lens. Did check the back posts but not sure.

Thanks in advance.

Why the GH4?

[franklin]

Because I can get the body for less than $1000. This is a one off project so I don't want to invest too much money. With that said I am open to suggestions.

Thanks

So basically, you've got a zillion choices, since the number of slow manual and AF primes is unlimited. What's your budget like?

There will be as many answers as there are forum members, but if you're on a budget, the Samyang 12mm f/2 is a low-priced wide angle if you can get in close enough to the action. The Panasonic 42.5mm f/1.7 is an excellent focal length for portraiture, and is priced under $400 new. Another option for head and shoulder shots might be the Sigma 30mm f/1.4 DC DN, which sells for a fraction over $300.

10 bit GH5 is very handy for the greenscreen. Pana 25mm 1.7 is very good (there's a 1.4 version that's a bit pricier), as is the 42.5 1.7 that Jon mentioned. Samyang sometimes sell as Rokinon.
