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

OK, had another quick play yesterday. Trying different AF modes and still struggling with the birds head-on, but I think that may be me more than the camera. The mirror blackout is longer than with the 1Ds, which makes tracking during a burst harder and I don't normally shoot in burst mode either so it's not something I'm expert at.

What did impress me was the ability of the camera to keep on the target and not get distracted by obstacles coming in front. Each of these is from 2 consecutive frames.



My normal style of shooting seems to be yielding good results. I think the challenge of birds head on at close range is probably tough for any camera since the lens focus has to move a lot very quickly. Really looking forward to the chance to give it a go on some wild stuff.

That's better Paul - my gut feeling is the AF system will be the nutz. I don't shoot long bursts either - I tend to pick my moment and either take a single shot, or sometimes a burst of 2 or 3 at most. I'll give the longer sequence a try though at the first opportunity.

A couple of shots from this morning...

3200 ISO

800 ISO

No NR run on these and what slight bg noise there is would be very easy to deal with in processing. 3200 ISO looks like it will be very usable.

I'm starting to seriously love this camera already. :love:
 
Darn, these pretzels are making me thirsty! I may have to rethink my waiting until Aperture 2 is updated strategy!

Just waiting for a quote from Stuart on the 7d and some other bits before I make my final decision!
 
Ha ha, I bought the last one in stock from Stuart this morning, will be with me tomorrow.

I'm supposed to be studying for my exam next week, but doubt I will get much studying done tomorrow.

Charging my batteries up today to be good to go when it arrives!

LOL. You'll love it mate and with the 5D2 as well,you'll have all the bases covered. :cool:
 
When I was looking through the pre-release threads and reviews, there were a lot of people (were they Nikon users?) who seemed to think that the 7d would be useless at high ISO because of the noise. There was no discussion about not using all the pixels though.

The following two pictures are 800x600 crops from a 6400 ISO image, and an 12800 ISO image.
6400

12800


For me, if I have to go to a high ISO because there is no light (this is with flash and 'energy saving lightbulbs' at home! energy saving mutter mutter), I could deal with a bit of noise. Also, I would rather get an image than not be able to, so these are set as MRAW (same MP as 40D/400D RAW). There is no noise reduction (either in camera or DPP) set on these.
Ok, so maybe not an A4/A3 print, but is good enough for a screensaver. A shot is better than no shot though.
 
Got mine about 15 minutes ago, a big thank you to Stuart at Digital Depot for the great price and prompt delivery.

Already taken about 30 shots with it around the house having a play and apart from the shutter sound (which is horrible) it seems really good. Took a few minutes to set the custom settings to match as near as possible to my 5DMk2.

Bleddy hell 8fps is fast, never had a camera that went that quickly before.

Nice to have an onboard flash again too!

Af seems quick and precise, but only some further tests will confirm this, I am going to pop down to the flyover bridge over the A38 dual carriageway in a mo (about 800 yards away) and take some piccies of the cars coming towards me and see how it copes with the 300 f2.8 and the converters. Should be a giggle.

I think I will have to invest in some faster CF cards as the buffer fills up really quickly at high speeds.

All looking good so far (well apart from the fact I am supposed to be studying) and looking forward to using it properly at the end of next week when I get back from Bristol.
 
I don't get this shutter noise thing. I genuinely think mine is the quietest shuttered camera I've owned and it sounds more like my old 1DII but quieter! It has to move the mirror quickly so it will have a different sound to many of its predecesors. The 5D sounds like a wet fish flapping around...
 
Hi,

this thread has now become my most hated on the net :razz::'(:eek::shake:

But I can't help coming back to it :bang::gag::lol:

Mike.

140 RAW files on a 4gig CF card is about your lot too!

Thanks!

These were all taken using a Sigma 120-300 f2.8 EX DG HSM, apart from the first two which were taken with a 24-105 f4 L IS.

Maybe I am on the wrong setting (default, not liveview). But I took a shot last night, and had the wife asking what the noise was.
This camera sounds like it is a very heavy/sturdy mirror hitting the stops. It seems to 'last' longer, and sounds lower (it sounds slower), than my previous camera.
 
Well I've been down to the bridge and had a play at shooting moving cars.

All images were taken above the outside lane from about 600 yards away until they were too close to keep in the viewfinder. The average speed on that stretch is about 75mph but sometimes you get the odd faster one.

these are straight large jpgs from the camera, no sharpening, no nothing!

Hopefully the mods will allow my indulgence as I have a burst of 6 at 300mm 1/2000 sec @ f4, ISO 640, AI Servo Focus, High speed drive!

Guys, please stop saying how good the 7D is, its going to have a very negative impact on my finances!
 
Burst of 8 at 600mm (300mm + 2x Converter) Straight jpgs from camera.

Now I grant that they are not brilliant, but that is probably more down to me than the camera as I have not done anything like this before.

Quite fancy trying to do some Horse racing or speedway shots now!
 
His tax disk is out of date :lol:

The images with the teleconverter dont look as sharp, is that a focusing error or just due to the teleconverter?

I suspect it's subject movement as I forgot about the effect of the teleconverter and didn't take the ISO back up, so it's dropped a stop.

Eight frames a second means that at 75 miles an hour the car travels about 14 ft between every frame.


75 * 1760 = 132000 yards an hour

13200/60 = 2200 yards a minute

2200/60 = 37 yards a second

37/8 = 4.6 yards between frames

4.6 * 3 = 14 ft between frames

I am still probably about 50 yards in front and 30 ft above the vehicle in the last shot.
 
So anyone who can tell yet how the 7D copes with reds and flash?:nuts:
 
That's a good real world test, spot on for a motor sport photogrpaher ;) and it looks like all is well. But as far as spot on accuracy test is concerned, there's too much depth of field at that distance for a critical check ;)
 
EdBray
thats a good test and looks on par with the mk3 too.

Both 'as shot'

3976100201_15ac1870a2_o.jpg


Had to use the pop up flash for this - I've lent the 580EX out for a wedding today. Doesn't look too bad although I suspect you're looking for examples where flash is a bigger percentage of the illumination - indoors probably?
 
There's a discussion over at dvinfo about 7d's overheating when shooting video, has anyone experienced this problem from leaving the camera in live view for a long time?

Thanks for that CT :thumbs::thumbs:

Would like your perspective on whether it faithfully reproduces reds/pinks/purples when flash is used.

I battled for some time to get it near acceptable on my 1Ds and 5D...Nikons seem to cope much better with reds and flash although I would really hope that Canon is getting this on the penny with the new technology in the 7D...

Well that is a problem I know, but hopefully, the new colour based metering system in the 7D should be a lot better.

This is probably a fairer test...

The left shot was taken under ambient artifical room light with the wb set to 2500 degs Kelvin.

The right shot was taken in the same light using AWB and the pop up flash.

3977050049_16d5d5c905_o.jpg


Apart from the flash shot looking a little brighter, which is normally the whole idea, I'm not seeing any nasty colour shifts, and the shots look faithful to the actual box colour, so it looks promising, although you'd need a variety of different hues in the pic to come to any firm conclusions I think.

Not sure I understand this. If the camera is capable of accurate colour, it should be capable of accurate colour with flash. Sure the flash might have a tiny bias (often towards blue) and different guns can vary slightly but if it's really that critical then a custom white balance should sort it. Or post processing :thinking:

Had a quick play with a 7D in Jessops today, with an EF-S 17-55 2.8. Compared to my 40D... Nice viewfinder, though not the night and day improvement Canon seems to be suggesting. Superb LCD. I like the control layout and new buttons. Very fast frame rate and yes it does sound a bit different, but not noticeably louder/quieter or better/worse, just different.

It feels great and has that very fast, responsive feel to the AF and shutter release that I've only noticed on the 1D cameras and top end Nikons. First impressions, albeit very superficial, are that it is just as good as I expected/hoped, and I'll be getting one some time in the new year.

They also had some sample prints, about 10x7in taken in the local square at a range of ISO settings. Only casual snaps, default JPEGs run through the regular processing machine, but that's the kind of test I like. If you can't see any benefit in ordinary pictures, then it's going to be marginal. However, they were very impressive. Just on a visual check of those I would say noise is at least a stop better than my 40D, possibly two. Given that it's almost double the pixel count (10mp to 18mp) that's a sensational performance. The sensor and related image processing are obviously a bit special :)
