I'm looking to buy my first pro camera but don't have the budget for a new lens. I have an amazing EF mount lens for my eos rebel t2i. I'm thinking of getting a black magic pocket but since the lens has a digitally controlled aperture I'm worried that if I use it on a different brand I won't be able to adjust the exposure without changing ISO or shutter speed.
All EF Mount lenses use an electronic aperture control. Never a mechanical aperture control. In fact the EF Mount is 100% electronic. There is no mechanical interface that includes autofocus. If the camera has an EF Mount the lens will work. I am NOT sure about EF-S lenses. On the Black Magic Cinema cameras. I think that there Full Frame not APS-C. Thus making EF-S lenses incompatible.
Having said that, what specific lens do you have? If it's EF, it would work. If it's EF-S, it may work. The blackmagicdesign gear that has an EF mount are both using a Super 35 sensor which is very close (but not exactly the same) as APS-C like your T2i uses. So it's possible that an EF-S lens could lead to strong vignetting in the corners.

But which is the best model for you? There's certainly a big price disparity between them, with the 6K Pro cost around $1,000 / 1,000 more than the 4K version. But there's also plenty to differentiate the two and, in the case of the 6K Pro, potentially justify that extra cost.
The Blackmagic Pocket Cinema Camera line may never have actually been pocketable, but it's always represented exceptional value for prosumer videographers looking to capture cinematic footage without spending the earth.
At the heart of the Pocket Cinema Camera experience is an exceptional array of ports, including a mini XLR for audio (one on the 4K, two on the 6K Pro), a full-sized HDMI port, 3.5mm line-in, headphone out, and support for high-speed (and high-cost) CFast 2.0 cards, or more affordable SD cards.
The two cameras also share many of the same shortcomings. Neither, for example, deliver battery life that can hold a candle to the Sony A7S III or Sony FX3. Additionally, no Blackmagic Pocket Cinema Camera has a fully articulating screen, something that will put off vloggers instantly. Need continuous autofocus? Then you need to look elsewhere. For everything the Blackmagic Pocket 4K and 6K Pro can do, they can't lock onto a subject or elegantly focus mid-capture.
From a practical specs and usability point of view, though, there are seven key differences between the Blackmagic Pocket Cinema Camera 4K and 6K Pro other than price which will dictate which is right for you...
Neither the Pocket Cinema Camera 4K or 6K Pro are compact, but if you want the more convenient option, the 4K is it. Hardly surprising, given the fact it sports a smaller sensor, fewer mechanical features, a fixed screen, and one less port. The size difference between the 4K and 6K Pro mean accessories for one won't fit the other, and cases and bags might also not fit both cameras either.
Getting into specifics, the 4K weighs a light 722g, while the 6K Pro comes in at 1.24kg. Neither camera is weather-sealed, and both sport plastic bodies, so could have been significantly heavier, but the 6K Pro is the weightier option. It's also over 2.5cm taller at 12.3cm, and almost 3cm deeper, than its sibling. That said, the two cameras are roughly the same width, so if you have a horizontal open-top cage, it could be compatible with both.
This sensor size difference also results in a different crop-factor, with the Blackmagic Pocket Cinema Camera 4K giving you a 1.9x crop, while the 6K delivers a wider 1.56x crop. Depending on what you love to shoot, this will affect you differently; wide-angle lovers who will want maximum information in-frame will prefer the 6K Pro, whereas anyone who needs maximum reach at 4K could be well-served with the more affordable Pocket Cinema Camera 4K.
Both the Blackmagic Pocket Cinema Camera 4K and 6K support 2,000mAh Canon LP-E6 batteries, which have been keeping DSLRs alive in excess of 15 years. The official battery life quoted by Blackmagic for the 4K is 60 minutes on a single charge when shooting at 24fps, however, we found real-world use was significantly less with our preferred settings, nearer 40 minutes.
The Blackmagic 6K Pro has been created to be kitted out a bit more than the 4K or vanilla 6K from the offset. In addition to a more elegant battery grip solution, which connects with pogo pins rather than a dummy battery, you can grab an OLED electronic viewfinder (EVF) for it too.
There's something to be said for buying a camera that plays nicely with your existing lens collection, and if you're anything like us, a big deciding-factor between the Blackmagic Pocket Cinema Camera 4K and 6K Pro will be the glass you own.
