Dr., you have some decisions to make! . . . As far as CF vs SD, I have no real preference. CF is a little larger and easier to keep track of & handle. I do not see the reason to hate them.
I do for sure have some decisions to make and think that I am closing in on them. As you pointed out, cost is a major factor. I don't like having a lot of $$$ wrapped up in equipment that overnight become dinosaurs. I am reminded of my HVX200's that I had and all those terribly expensive P2 cards, why I had nearly 20 grand in that bundle with cases and lens attachments only to learn that it was all my BIG commercial dual xeon HP units could do to edit that stuff let alone multi cam was virtually impossible. But fortunately i thought ahead, perhaps like now, and within the first two years of ownership unloaded them on other new "wanna be" hi def'ers and recovered at least 80% of my capital. Now just the other day, for the heck of it mind you, I looked on ebay and a camera with multiple p2 cards and hard panny case like i had sold for under a $1000. Geez! Just one P2 card was more than that. Yikes!!
SD vs CF isn't easy. I love the robust look and feel of the CF. I especially like that when inserting into a camera it feels like a tiny film canister as opposed to the tiny flimsy feel of an SD card. However, in defense of the SD card matter, it is much easer to slip into a camera in a rush, a hard metal enclosure water proof case with six to eight cards in it fits comfortably in my pocket, virtually every consumer and prosumer and more and more pro gear now use it, the price is easy pocket change for excellent quality ones, and finally (perhaps as important as all the above) there is a slot in my mac that just loves the things. Moreover, I have actually edited video footage and photo images right from the card including keeping Premier Pro and/or Lightroom project files on the card. In fact, the price of the card has gotten so low that one can almost consider them a "floppy drive" concept and at less than a buck a gig now for SanDisc's, the floppy idea is certainly conceivable. I only know of one photographer who bent a pin on a CF and I dare say I would never want that to be me. At my suggestion he found a solution in CA that was able to resolve.
On the SDOF issue, positioning-framing and lens choices help a lot in that area. Moreover, I think my video work with a 5D M3 would be limited to movie style shoots and/or good $$$ docs. Otherwise I'd just use the easy to run XA20's. The latter positioned far away and zoomed in make some pretty amazing SDOF look/feel.
Lastly, I think I owe it to myself to examine this 6D a little closer, get more behind the lens time with it (yuck) and see how it's video looks in my hands and on my computer. Watching comparisons online just don't really work for me because by the time YouTube gets through compressing all the digits out of a video it often looks like garbage regardless of whether the source was a cinema or an iPhone. I think I need to MAKE some samples of my own and just make/see if I'm happy with it. After all, it uses SD cards AND I don't need all the extra bells and whistles … like a zillion AF points, I either manual or use center only even when picking outside the center for focus, therein I merely point at the bg or fg subject, push half way to AF, then move the camera carefully to frame the picture. I mean on the 5D M2 I moved the AF point once or twice at the most and even then just to say I did and that I knew how if I ever needed it. The former method was my go to process.
The thing I don't like about the 6D coming from the 5D2 (and Im sure 5D3) is the positioning of buttons and the zoom in/out features that are both uncomfy locations and not responsive to my desire. The 60D button configuration would be much more to my liking but I've already considered it and don't want to give up my FF imager.
No, I think I've concluded that for now, I'll stick with what I have unless I am ok with giving up my FF and moving to a 60D for stills, opting to collect off the difference and then some to get a C100 since that will give me something better.
QUESTION: One question I do have though about the C100, since it appears to be a crop imager, is there a FACTOR to consider with lenses like the 1.6x crop factor on the Canon crop cameras? Or is a 50mm lens a 50mm lens to the C100 or is it an 80mm or the like?
