I’ve been pretty happy with the Sigma 17-70 F2.8 It works for most of what I shoot except extreme telephoto and extreme wide angle. .

TOTALLY correct. The 4×4 filters would have been several thousand additional dollars. I work with some directors now who just want everything recorded crisp and clean so that digital filters can be added later as desired. The rails and cage were budgeted separately because they came from different sources.

Any difference in quality should be indistinguishable when both are using full frame lenses. But you probably will need a shorter lens with the 2K Cinema Camera.

As I understand it EF-S lenses don’t work on FUll frame sensors. Full frame EF series lenses should be downwardly compatible with APS-C sensors that are in the Blackmagic 2K cinema camera.

Well… it all is a balancing act. Higher quality means larger file sizes. FYI… even though the C100 has a full frame sensor it does not record in 4K. And you will still have some of the same issues with the C100. And there are serious compromises in the way the C100 handles color. The C100 has a 4:2:0 colorspace versus the Blackmagic which is a 4:2:2 colorspace. That makes the Blackmagic a huge advantage. And the way the C100 gets those small file sizes is by using AVCHD which can be pretty compressed.
Here is comparison as to how much compression each camera has:
Canon C100 at 24MBS – 1 hour of record time = 12GB
Blackmagic Cinema Camera ProRes HQ – 1 hour record time= 120GBSo you can see how much compression each camera has. The C100 is literally 10 times more compressed. Compression = digital artifacts and a loss in color resolution.
I don’t actually edit the prores HQ files. I convert them to much smaller proxy files and edit the proxys. Then when I’m satisfied with the edit, I reconnect all my files to the Prores hq files and output the final file.
But all that is relative. And if you need convenience features then the C100 is the obvious choice.

While you can buy compatible EF or ZE lenses for both cameras, the BIG issue will be achieving the desired composition at a given subject distance. And for that you usually want a variety of lenses of different focal lengths to give you flexibility when you are shooting. The BMCC with it’s APS-C sensor really benefits from shorter lenses. The 4K Production camera..not so much.

The two questions / comments you had:
What is the size of the 4K files?This is pretty easy to figure out. 2K files generally record about 2 milion pixels and that translates to about 120 GB per hour at 29.97 frame rate.
The 4 K files are basically 4 times 2K or about 8 million pixels. So you should be going through about 480GB per hour if you shoot prores
“i know the internal battery life is poor in the blackmagic but because of the low price tag means i can easily afford all the extras, especially compared with the price of the C100”
Blackmagic was VERY forthright in identifying the battery life as being a maximum of 90 minutes. The ACTUAL life of the internal battery depends on several factors. If you set the brightness up to 100% the battery will not last as long because extra energy will be expended in the form of light being displayed on the viewfinder. Additionally different SSD drives have different power consumption rates. So unless you are only going to shoot for a few minutes doing some extremely portable hand-held work, you will probably need a battery system that will last for 8 hours or more. That will mean at least 2 batteries for most shooters.
The BMCC camera consumes on average 16-22 watts of power at 12VDC (14.4 volts, nominal). So I always have four BRIKPOWER batteries when I shoot in the field. I can run for the better part of two days with only four batteries without recharging. You can buy these on ebay at a fraction of the cost of some other batteries.
We don’t really know what the exact real-world power consumption rate on the 4K cameras will be yet because there are so fe wof them out there. (I know of none in my area). We think they should be comparable to the BMCC though.
As you know most PROFESSIONAL cameras do not have “internal” batteries. Most pro cameras come equipped with the ability to accept either “shore power” or a traditional block-style battery. When you connect the batteries to the Blackmagic Cinema Camera what happens is a bit different from their Pro counterpart cams. Any time you connect power to the BMC Camera (AC adaptor or Battery) it begins first by charging the internal battery. This happens whether or not the camera is turned on. And it happens with the AC adaptor or if you use an external battery. So even if you are not aware of it, the battery you connect could be partially drained off by silently charging the internal battery.
The BRIKPOWER batteries i mentioned earlier have a switch and a bright red indicator light to help preserve your options in this regard. You can simply switch off the battery to avoid having it drained off to maintain the internal battery.
You can buy BRIKPOWER batteries and chargers on ebay. https://www.ebay.com/itm/BrikPower-BMCC1A-Battery-for-Blackmagic-Cinema-Came...
SO…The battery on the BMCC should be probably thought of as a convenience rather than a primary battery and reliable source of legit power.

If you have not found a battery system yet, check out this one from BrikPower: https://www.ebay.com/itm/221337096470?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
I developed the battery and it is incredible. One battery will last WHILE RECORDING with viewfinder at 100% will last for 4 hours. And they are mounted in a cast aluminum case – NO PLASTIC.
Our BRIKPOWER Battery comes with one, 3 foot long BMCC power cable AND a 12 foot extension cable to place the battery power somewhere other than at the camera head (using a teleprompter or placing the BMCC on a jib arm).
I’m a Cinematographer. When I began to investigate what battery I wanted to use with my own BMCC camera I discovered that I wanted more from my battery. Our battery is intended to be mounted behind and below the camera for an unobstructed view of the BMCC viewfinder. BRIKPOWER is tough. We skimped on nothing. This battery system is ready to be mounted on 15mm rails and comes with TWO integrated Aluminum rail blocks for that purpose. Having dual rail blocks distributes the battery weight with 4 locking points so that the battery is secure. Each battery has it’s own set of rail blocks so changing the battery is a fast, painless process.
BRIKPOWER – Battery Power for Blackmagic Cinema Camera.
CAST ALUMINUM HOUSING 3″ x 4″ x 5.5″ to fit perfectly with a rail mount
15mm RAIL BLOCKS FOR MOUNTING ON CINEMA RAILS ARE INCLUDED
LED INDICATOR LIGHT AND DISCONNECT SWITCH
LASTS UP TO 4 HOURS WITH BMCC
3′ BMCC CABLE AND A 12′ EXTENSION CABLE ARE INCLUDED
DESIGNED specifically TO WORK WITH BMCC

I’ve been following these audio issues with a keen interest. I’m wondering why Blackmagic would release a camera with all these audio issues. I only began investigating what I should do to solve my own audio problems with the BMCC and was assuming I was doing something wrong. Would anyone like to join in a class action lawsuit? I’m meeting with my attorney tomorrow.
