I've been working with a Blackmagic Pocket Cinema 6K camera for several months now. It's hands down the best camera I've ever used, video or still. Its 19-megapixel sensor can capture stills or 6K video (hence the name) that's up to broadcast standards. It has a large touchscreen which makes adjustments easy and quick. And boy is it customizable. It has a wide variety of automatic and manual settings that I'm still learning to use. It also has a full-sized HDMI port and a USB port for an external hard drive.

There's only one thing it doesn't have when you buy it: a lens.

That's right, it doesn't come with a lens.

That may seem kind of weird if you're an amateur photographer. Blackmagic Design is selling something that doesn't come with everything it needs right out of the box. But, if you're a photography or video buff, this likely doesn't surprise you. Camera bodies have been sold without lenses for at least as long as I've been alive. This lets the user choose the right lens from a bewildering array of choices. Since getting this camera, I've purchase three lenses which I've used for different purposes.

Which lens should you pick?

The first question is, of course, what do you want to do with the camera? For most users, a zoom lens is the right choice, but if you want the absolute best quality you might want to choose a "prime" lens. (That's the proper term for a "non-zoom" lens.) Prime lenses are less versatile but often provide a level of sharpness and sensitivity that you can't get with a zoom lens.

The next choice you'll want to make is the focal length of the lens. This doesn't always refer to the physical length since a lens can have several elements within it that allow it to be more compact. The "longer" the lens is, the more you can zoom in. A 35mm lens basically gives you a field of view similar to what your eyes see. Anything "shorter" like 18mm will capture a wider area but the edges may be distorted. With a very long lens, you can capture distant things as if you were right next to them. There are other benefits of different-sized lenses, but this isn't an in-depth photography course. If you're curious about that, there are plenty of other sites to read.

You should also consider the way the lens attaches to the camera. Blackmagic cameras use Canon's EF-mount. Lenses for other Canon mounts or for Nikon cameras won't work without an adapter, and those adapters can create problems that you want to avoid.

Simple answer: choose the biggest and most expensive lens you can.

There really is a difference between a cheap lens and an expensive one. You'll want to look for these features:

Big front lens

A lens that's got a big chunk of glass on the edge will perform better than one with a smaller front lens. Ideally you want the part of the lens your camera actually uses to be as flat as possible, so you want a lens that's large enough that the part that slopes inward is far from the center.

Actual physical size

As I said above, some lenses have many different elements in them. Having multiple pieces of glass essentially allows the lens to fold in on itself, reducing its physical size. However, the more glass you put in a lens, the more distortion you get and the less light reaches the sensor. An 80mm lens that's 10 inches long will always give you better performance than one that's 5 inches long.

Cost generally equals quality

When you compare the price of any two lenses, the more expensive one will generally have better construction and better optics. You can buy used and refurbished lenses instead of new ones, which will allow you to get a better lens at a lower price. But in the end, the lens is an incredibly important part of your camera. The same camera will give radically different results when used with a $50 lens compared to a $500 lens.

I get it, the camera itself wasn't cheap. But if you want something that will really show that camera off, choose a lens that's up to the task.

SUPER IMPORTANT: Choose a Canon-brand lens

The Blackmagic line of cameras use Canon's EF-mount lenses. This opens up a whole world of possibilities for you to choose from. However, in the summer of 2023 the company rolled out Firmware Version 8 for its cameras. This update takes away the ability for non-Canon lenses to set auto exposure and auto focus. The company acknowledges the problem but has not committed to a timeline for fixing the issue.

The problem seems to have something to do with the way non-Canon lenses actually interact with Canon cameras. From what I understand, Canon does not publish the technical specs of their lens "communication protocol." This means that camera and lens makers like Blackmagic are left to try to figure out how motorized lenses actually talk to the camera. It's not super clear why, but Blackmagic's latest update doesn't talk to non-Canon-brand lenses very well.

There are some excellent third-party lenses for Canon EF mount, but for now I would stay away from them.
