Canon announces EOS 7D ***Official Discussion thread***

CT said:
Interesting thread on POTN showing ISO performance of the 7D compared to several different cameras - looks excellent actually.

Thanks for that CT. Looks interesting although web resolution is always hard to tell.

I took my decision to pre-order pretty seriously and part of that process was printing the sample shots from Rob Galbraith and The Imaging Resource at A4. The results were certainly interesting.

1. The Galbraith pictures shot at a gig look worse that the studio set-up at Imaging Resource. I would expect that as there is a lot more shadow in the pictures of the gig.
2. I have come to the conclusion that ISO1600 at A4 is pretty good without noise reduction and 3200 with. This is more than enough for what I shoot anyway.
3. Like all EOS cameras, exposing to the right will improve noise response

I agree with all that Paul.

I've been playing with every sample image I can find and I've come the conclusion that I'll probably be able to use 1600 ISO (which I do sometimes now anyway) and it will be markedly better, and 3200 at a push with a bit more processing, and that's taking pretty large cropping into consideration.

It's very noticeable that the quality/nature of the noise is much different too - being more like grain in film and far less objectionable.
 
I hope the "grainy" nature should also be easier for NeatImage/Noise Ninja to process.

Have to say that thread on POTN makes us look like we all get on over here!

Mercifully I can't post on there anyway, but I do have a look occasionally if there's anything interesting.
 
That ISO comparison is certainly very interesting. The D300 @ 6400 looks terrible doesn't it!?

I've just found another sample video from the 7d which has rekindled my interest in that aspect of it... I'm just not sure how usable it will be with no constant focus! :shrug:

I saw that - stunning - not that I know zippo about video stuff. :shrug:

I can't see me using it other than playing about. Like most people, I've toyed with the idea of a video cam at times, but all the people I know with one walk about with it glued to their foreheads for about a fortnight making Steven Speilberg noises, and then they seem to disappear once the novelty has worn off, so this at least saves me from buyiong a whim toy I probably wouldn't use.
 
:bonk:Ahem sorry!!
My excuse is I am at work trying to read this at the same time!!
 
I would wait-If the 7D tracks anything like the 500D and 5DII it will be about 60-70% of its RRP by Christmas(£1150)!!

See my post 202 on page 7 of this thread!!

"The AF mode will be the same as described on pages 138-144/ You can select [Live Mode], [:-) Live Mode], or [Quick Mode]. Note that continuous focusing of a moving subject is not possible."

That rather limits it's appeal for me! :(

Yeah I had read that too. But in Live mode, it does perform contrast based detection ([or at least, my understanding of contrast based detection, determining whether a circle of influence is increasing or decreasing] and face detection). If you look at the links I posted a couple of days ago, you can see that it isn't perfect, [but almost as quick as the camcorder I have anyway. ]

I would like to know whether this was manual, or AF focus. It seems a bit slow for manual, but decent enough for AF (for me)

Do you mean the Phil Bloom short? I can't see any auto focus going on!?

The live view focus mode on the 50d requires you to press the AF-On button every time you want to focus, it doesn't track. I think the 7d works the sme... not that much better than manual focus for shooting video IMO.

No, there was someone playing with one of the cameras at a show (language sounded Germanic), and they video 'd themselves playing with the video (and live-view). I believe there are two ways of focusing, either with pressing the shutter half-way, or with the AF-ON button. The first is a temporary focus, as if you are going to take a photo, the second appears to be a permanent focus, so long as you don't have quick-focus selected.

I think TBH. we are not going to get any clear answer on this, until we get one in our hands.
As for me, I am hoping that the 7d will be a camcorder consolidation, so having to manual focus is not going to be a major problem. It would be nicer if it does auto-focus, as most of the things I did video, I would be watching with my eyes, and pointing the camcorder in the rough direction. If it requires manual focus, it will require a bit more concentration.

Again, depends on what you mean by track. I think it was a single-point focus/face detect, that was tracked going forwards/backwards, not across the screen.

Neither appear to adjust the focus when the subject moves in the frame, or if the camera moves, like you would expect of a dedicated camcorder (and not a DSLR admittedly).

I think you're right, manual focus would be ok and the results that people seem to be getting with it are pretty impressive.... although they may all be seasoned/experienced videographers for all I know!
 
Has this manual been posted? Just had a quick skim through the 11 pages on thread, and can't see it.

This is a PDF of the official 7D manual, not the Canon website info - Should keep you going until it arrives!

When are any proper reviews out for this?
Click to expand...

Not till a final production version is available. The camera doesn't ship to dealers till late September, so I wouldn't expect to see a full review till well into October at the earliest.
 
If the 7D is anything like the 5D Mark II in liveview, which from reading phil bloom's stuff it'd seem so, the autofocus is pretty much as good as not there. Just trying it not on faces but a simple point it at something and then at something else, took 20 secs to hit focus with using contrast detection. Pressing the shutter half down whilst in movie mode does nothing.
 
Perhaps the way around autofocus, is just to shoot on the smallest aperture, largest DOF possible, like the film above!
 
This looks really promising - a field review by the Norwegian wildlife and bird photographer Ole Jorgen Liodden. The English translation is a bit iffy in places, but this guy is clearly very impressed with the 7D - the AF system in particular, which he rates the best he's ever used.

That 100% crop of the goose is impressive. Only 500 ISO, but no noise that I can see really, in the dark of the eye.
Now, if only I could afford the lens he used as well. I think given what this camera is suited for, this is a really good find for a review.
Thumbs up CT
 
Well I don't mind admitting I'm excited - this looks like it could well be the camera I've always wanted Canon to make. :cool:

with you all the way ,just wish the shutter was quieter .
Rob.
 
Oh, ok, I disregarded that type of video. There is no reference for how much amplification there was on the sound source.

Also, surely, it would be quieter with a lens on the front?

Thanks for the link CT - hope to get some UK reviews soon too... Still looking very impressive on paper and in early reviews.

Didn't sound too bad to me. Similar sound to my 1DII at 8fps.

stew1982 said:
does anyone like the new shutter sound?
Click to expand...

Not particularly but its just a sound. I'd rather judge the images...

Anorakus said:
Does it sound like the 5D mk II, i.e. quiet but almost as if there's a motorwind in there? :thinking:

Not to me, sounds more like a 1DII. 5DII shutter is very slow.

crumble said:
would not swop my 50D for one, rather buy glass
Click to expand...

Probably sensible. I know CT and I both have pretty good glass to pop on the end when our 7Ds arrive though. More to the camera than the sensor, also AF, metering etc. If the 50D is good enough for you, no reason to swap.
