The Canon T2i or the Panasonic GH2 are about the cheapest used cameras you can buy today that can produce a good video image.
If you can afford it, I would look for a used Panasonic G7 camera that you should be able to buy used for about $400. It can shoot 4K video which gives you a lot more options in post when delivering a finished 1080p video.
The Shogun Inferno is the only other Atomos monitor-recorder that can handle 4K 60p 10-bit 4:2:2 format, but it costs a lot more.
If you buy the GH5 and want to shoot 4K 60p 10-bit 4:2:2, then only the Ninja Inferno can record at this frame rate. ( if you don't need 60p recording in this format then the Shogun Flame would work just fine )

The three lenses that Michael owns are the best of the Voightlander lenses, the 10.5mm has some imaging problems so it's a lens I would pass on.
If you can't afford them now, then buy what you can, and look for good deals on used lenses. ( I do see used Voightlanders from time to time )
Also, these lenses will keep their value, so if you need to sell them you can get most of your investment back.
>>>Arri Alexas are so popular because they have 8.6uM wide pixels, which is the reason it has almost the latitude film does.
The Alexa's 8.6uM pixels allow for it's low-light performance, where it's wide film-like latitude comes from it's Dual Gain sensor architecture, that is simultaneously combining high and low gain 14-bit images to create a single 16-bit HDR image. The process is similar to HDR photography, but both Alexa images are derived from the same exposure.
