So... there is a 7D now...

define "useful..."

 

The form factor of being able to do decent follow focus on even one or two lenses in a kit makes this idea worth pursuing. The camera reminds me iin some ways of what used to happen when the ziess super speeds were new - they would out-perform the optics of the eyepiece and so you couldn't really judge just how good your critical focus was. Up until now the 5D mk2 camera couldn't get a good image to a monitor while recording, and without an optical viewfinder you never really knew if you got the focus or not. Now it seems the firmware has been hacked by the Magic Lantern folks to enable the 5Dmk2 to show 1080i via HDMI cable out while recording. The crippled camera just dropped another one of its crutches in the hospital corridor... it may never fly but it is damn sure about to walk a mile... with a big grin on its face.

 

The canon 5D mk2 will shoot a pleasing image in very very dark places and basically outperforms anything else going when it comes to that sort of shooting. 1600 ISO with a 85mm f 1.4 looks great. Of course, it's in 30p.... and a very compressed codec but still it "pushes the envelope" of what's come before it.

 

The 7D is pretty cool, too since it shoots 24p. It's a gadget, sure but dang pick one up and you get HOOKED. I'm convinced there is a niche for these cameras, and it has something to do with the stealth factor and it's ability to work well in low light. For indie film makers, it is affordable and tempting but has various "cripple factors" that are not easy or fun to deal with... but still. As a tool, I am glad people are figuring out how best to exploit it. It's not the ideal verite camera either but it seems great for stealing shots with just a couple of actors and a director, you know, sneaking into the Louvre or something.

Yeah, I thought about that and betting one to use with my longer PL lenses and use normal Canon still glass for wider lenses, but I'm just concerned they wouldn't match at all, besides I would have to find a way to gear the Canon glass so I could have a follow focus.

That's something I always wondered, about stealing shots, specially in famous locations. Is it just a matter of stealing the shot? Meaning if you can get away with it on the day you can get away with it and they can't say anything else? Can't the Louvre direction for example sue you if they see their location in your film and realize you had no permission?

May I get a clarification on a point? Does the 5D and, presumably, 7D take Nikon MF, non-automatic, (AI) lenses with adapter and still be able to control aperture and shutter manually?

Yes, like on the 5D2 the adapted Nikons work. There may be a very few lenses that protude too far in the body and block the mirror, but 95 % of them work. Since the FFD is different they do not focus to infinity. Not tragic for normal use though.

 

The 1,6 crop drives me nuts. Been using FF all my life. 1,6x is way more than i thought...

Thanks loads for an answer. May I ask further: Would replacing the 5D2 or 7D's lens mount (body side) with a custom Nikon cut or modified mount solve the FFD problem and make the Nikon lenses provide an accurate FFD? What complications might I expect?

Nikon FFD is greater than canon therefore infinity can be gained on all nikkors when used on a canon with any $20 adapter

I meant focus with a Nikon adapter is beyond infinity as its barrell mark. They do focus at infinity prior to that mark on most lenses.

 

Forget accurate marks on still camera lenses - Ive never seen any that are right !

 

Best to make your own marks (like on the FF disc)

Is it a little warm in here or is it just me? :rolleyes:

 

Just an FYI: The 7D has an overheating issue ("feature"?), vaguely documented in the user manual, with a related discussion about a month ago:

http://www.dvxuser.com/V6/showthread.php?t=182556

 

... and recently discussed in some detail here now that customers have them in their [hot] hands:

http://www.dvinfo.net/forum/canon-eos-7d-h...mperatures.html

http://www.dvxuser.com/V6/showthread.php?t=185339

 

The initial consensus seems to be that "continuously" shooting more than about 15-20 minutes of 60p or 50p video can cause the camera to issue an overheat warning, even in a moderate temperature environment in the shade. 24p, 25p & 30p shooting doesn't seem to cause similar problems.

 

Subject to further testing. YMMV.

Any news on the rolling shutter thing on the 7D? ... I still have these SD TFT LCDs. Will they take a signal from the 7D and not have to drop the recording format down?

 

Yes, the 7D CMOS sensor has a rolling shutter, but the artifacts it produces seem to be similar to what can be seen with some much more expensive CMOS-based cameras.

 

For example, here's a skew/jello comparison between the 7D and the 5DM2:

http://www.dvxuser.com/V6/showthread.php?t=185392

 

I haven't heard if the 7D exhibits CMOS flash band (partial frame exposure) artifacts, but I suspect it does.

 

Whether or not the 7D's CMOS performance is appropriate for a particular production is up to you.

 

The 7D has HDMI HD and composite SD live preview & playback outputs, including while the cam is in record mode. This topic & related applications have been discussed here:

Thanks for the answers, Peter. I was ambiguous and too brief in my questions. What I could have better asked was:

 

Can I see what I shoot on an SD monitor at the same time as recording to UDMA in HD? Can the 7D squeeze all that HD image down into my SD monitor?

 

Also, Phil had mentioned a difference between the CMOS pausing it's signal thus yielding less rolling shutter or simply slowing it's clock and exhibiting similar rolling shutter as the 5D.

 

Sorry about the vague questions.

FYI: This Vienna, Austria late night & early morning 1080p25 footage looks quite nice for a $1,699 US HD "video" camera body (plus lens, etc.):

There's additional info about this shoot on the Vimeo page.
