7D has manual control 1080p 24/25/30p and 720p 50/60p

I doubt I'll be pissed at all about any of the new VDSLRS, IMHO all of these cameras are 'transitional,' I just want a moderately priced, feature packed camera to get me through the next two years before the truly groundbreaking VDSLRs come out. Then I'll really break open my wallet. I think the 7D is the perfect fit for the time being.. I repeat, IMHO.
 
If I can get anything close to the 2 Canon samples out there so far I'll be more than happy before the "truly groundbreaking VDSLR comes out". Whatever that means.

Hey Kholi, you ready for another round?

Phase 1: "OH MY GOSH HAVE YOU SEEN THE SPECS?!?!? THIS IS THE GREATEST THING EVER!"

Phase 2: "Are you frickin' kidding me? No autofocus in HD mode?!?!"

:D Heh. Happens every time, with every new camera release...

my second fav sport after poking sticks at GH1 users

btw Barry it's 18mp not 14

I haven't read half the posts yet and I gotta leave for red school, now I'm thinkin "why am I goin to red school?"

Don't get me wrong, I'll be more than happy with the 7D, but there is PLENTY of room for improvement that I'm sure we'll see within the next few years. Off the top of my head: XLR inputs, HD/SDI out, advanced compression algorithms, >12 mins of recording time... This is what I meant by "transitional VDSLRs." As always, IMHO.
 
I think you're spot-on, hermmermferm. These will be transitional, but then again so's everything. I usually buy Canon still cameras, and I still have my little PowerShot SD500 because it had VGA res video at 640x480. Now, just a few years later we're looking at 1080/24p and 1080/30p and 720/60p in a "still" camera.

So they'll continue to transition, but for TODAY, the GH1 and 7D look pretty darn good.
 
Barry (or other experts) -- can you give a guestimate in regards to the aliasing? Do you think that the 7D (with a smaller sensor) will produce less aliasing than the 5d?

No possible way to know at this time. If I was forced to guess, I'd guess that it would be comparable to the 5D, assuming that they're employing similar technologies in the image processing section. But there's been a year of technological advancement between the 5D and the 7D, so who knows, it might be significantly better. Or the same. Or worse. We won't know until it gets in users' hands.

The sensor size is not important. Every camera has an antialias filter designed for a specific pixel size. Since this is a dSLR, the filter is designed for its native 4.3um pixel because they don't want a serious blur on their full resolution stills. In order to get 1920 horizontal pixels, you need to skip lines/coloumns from what could be a cropped size of 3840*2160 and get a bayer 1920x1080 image with an 1.35x crop factor vs the full sensor width. That image would be small enough for the DSP engine to debayer and process in realtime. The camera specs are 8fps at full res, so it will easily do 30fps on a 1080p bayer subsampling. The antialias filter is not effective when you skip pixels because it's designed for 4.3um pixel size not the effective 8.6um of a 1:2 subsampled output.

There is a way to do it without alias. Read the full frame size and downsample in realtime but that's a very heavy job at this pixelrate for the DSP and the sensor has to support the very fast readout. For 16bit 16:9, it would be 250 to 450mpixels/sec CMOS readout and realtime downsampling depending on width (5184 or 3840 pixels). I don't know if they attempt to do this and how fast their chips are. If they do, it will look wonderful at 1080p. It will also have no horizontal crop factor in video mode.

The pixel area of the 5DII is 6.41*6.41=41.09 sq. um.
The pixel area of the 7D is 4.3*4.3=18.49 sq. um, so it will get 41.09/18.49=2.22 times less light. More than a stop of difference in low light performance probably assuming similar technology.
 
Quick questions, will the DOF on the 7D be easier to pull than the 5DM2? I have worked with the 5D and boy, if your talent miss their mark by couple of inches you are screwed... Not owning a GH1 I have read its DOF its more forgiving

Since it's a smaller sensor I would assume...yes.
 
Okay... so those who are unfamiliar will know...

the 7D is pretty much right on with the Sensor Size of say, the RED. And RED is around S35mm size, the same size frame that nearly everything is shot on that you watch in theaters. Full Frame is not the current acquisition standard in Cinematography.

By acuiring images with 7D's image sensor you will be immediately within range of reproducing the same cinematic characteristics that everyone has been striving toward for so many years. Pulling focus @ Stops of 2.8 will be simple for the practiced focus puller. And even wide open at 1.4 it's not too difficult at all.

DOF, Angle of View, Field of View will be plenty good for this stuff. It's a very happy medium between everything, and works very well.
 
Thanks Ian-T, Mr. Hicks. Now I need to do a careful selection of prospective lenses... I know you had experience using the Tokina 11-16 2.8, any thoughts on the 16-50 2.8?
 
You know, you can get the Tokina 11-16, 16-50, and 50-135 with the 7D (pre-ordered through TigerDirect using the Bing cashback) for less total than the MSRP of the 5D Mark II kit. Isn't that crazy?
 
 
Thanks for the links ydgmdlu, I think I'll just stick with the Tokina 16-50 2.8 as an option instead of the stock lens, the rest will be primes
