p.2 #17D: The bottom line
I don't own a 7D, but from all the owners' comments I have read, the vast majority are impressed with the IQ and AF, and have no problems with noise.

To me, that suggests the minority of complaints are user faults, rather than the camera's.

p.2 #27D: The bottom line
1. Heavy cropping is not a problem. I shoot a lot of aviation and even with a 500mm + 1.4TC I sometimes still need to crop. The detail is impressive.

2. Low ISO noise hasn't been an issue for me. I will use some NR from ISO 400 up, but the files are way better than any other crop camera that has come out. Even at high ISO the grain is tightly packed and easy to remove.

3. Better than 40D from what I have seen.

4. Haven't used the 1DII but the Servo is much better than the 40D.

5. I haven't tested this, but I will soon.

For me the 7D was a great upgrade from the 40D. I thought long and hard about a used 1DIII for around the same price, but the 7D does the job better for me.

Petkal, buy the damn camera.

It's awesome, and the people tat don't like them are just whining.

Unfortunately I can not make head nor tail out of different feedbacks posted here and elsewhere.....there are conflicting and discrepant views and opinions.
So I'd like to get a brief bottom line from experienced 7D users.

You see, I don't need another fancy camera with tepid performance, however, I could always use a reasonably priced tool which will help me get my images, such as they are, in the following ways:

(1) Detail recorded and cropping depth. I think that one
...Show more →

1- great amount o detail
2-I only get to shoot this aroun 800-4000 and it looks great. Some "still life" shots I've done at 100-400 look great and in print, 0 noise.
3-yes the periph points are better than those cameras, and are very good in their own right. I recently shot the circus here in town, and I used periphery points so I wouldn't have to crop the image later, and the shots were in focus on ACTION shots. Can only image how great in a controlled situation.
4-The servo performance is better than a 30, 40 and 50D combined shooting. It's been said that the servo performance is on par with a functioning 1d3. Some folks say 1d3 has the edge, but it's also said a 1d3 that's functioning is better than 1dmk2n, and if the 7D is on par with the 1d3...you get the picture
5-the low light FPS drop is true, but considering I don't shoot the back of my stupid lens cap, I don't have any issue. I cannot think of a situation where the extra 4 fps would help me, if there was only enough light to make it go to 4fps. I forget the exposure reading it needs for this, but I think it's equiv to like 1 second f/1.0 iso 3760701357 billion. It came up one time for me and it didn't matter because almost all of the shots that night sucked anyway (not from the camera, but trying to shoot a band at 1/15, f/2.8 ISO 6400.

I read that and I think they had to have a few defective ones, because I report none of those problems, and I've put 15-20K on one.

Looks like he has a problem with his 7D. It's not my experience at all. Even at 100% it can be scary sharp if you nail the focus.

just a little sample .... simple shot - really.
ISO 400, 24-70mm L with flash bounced of wall/ceiling behind me.
processed to bring out the blues - my standard portrait sharpening - all in LR3beta2.

used off center AF point in expanded spot - to get the bird cage netting.

while not addressing the OP specific questions .... i don't find the low iso images to be bad at all.
No cropping do to 100% VF - love this feature.

I believe that (5) has been found to be "solved" by holding down the * button while shooting. Kludge, sure, but better than a bullet in your head. I didn't 1st hand verify it, though.

Art Morris is shooting a 7D with a 70-200 for close-in birds and a 1DMKIV with 500 or 800 for distance. He loves the camera, pic quality, AF, etc. He's written some reviews in his newsletters.

I have the camera and love it: best user interface of any Canon DSLR I've owned, though it takes a while to really get comfortable with and exploit all the customization the camera is capable of.

Peter, i know you like the silky IQ in low light. Your JPG best bet is 1D(s)3. Under the bright sun, there is no constraint for most canon bodies anyway.

Yes: in Tv mode, but not in M mode.

That is ... absurd. Such a ridiculous bug should be fixed by Canon... quite shocked they still didn't do it.

and now the doubters know why I returned mine and picked up another 1D2

WOW, it actually worked, tv mode, * pressed and fire away in low light 8FPS!. Thanks guys.

I'd still like to know how Canon pulled off a 'miracle' and added 3 million pixels to the 50D sensor and came up with less noise - or did they?

And apart from the obvious improvement in focusing and assuming I don't want video (which I certainly don't), what is *really* better about the 7D?

What features are *really* important and improved rather than just clever ideas that you won't use?

(1) Detail recorded and cropping depth. I think that one
...Show more →

It has more reach than the 5D2 which itself has more than the 1Ds2, so yes.

As far as more detail when not distance limited, I doubt it unless you are using a lens that fades at the edges on FF.


(2) Low ISO noise. When I view an image on my 19" screen, and crop a bit, say 30%, I'd like to see no objectionable noise at ISO 100, 200 and 400.
High image croppability does little for me if I end up having to do NR on low ISO captures.


it does start giving losing reach due to noise, even by ISO800 and certainly by ISO1600
and very largely by ISO3200

that said it won't look worse than a FFeven at ISO2000 when you re distance limited, it might nab a trace hair more detail and have a trace less capture artifacting and noise if you viewed it at the smaller size of the FF captured bird but it will never be worse (given reasonably similar sensor technology) than a FF or anything else when it comes to reach photos but at ISO3200 you certainly won't see a ton of more actual reach by any means, the reach really does seem to drop off starting above ISO800. And you certainly need proper technique to get all the reach at lower ISO, those are very small photosites you need to resolve crisply, the area of micro-DOF that renders the photosites is thin so you must absolutely nail the focus and have a very high shutter to avoid all sorts of blur, if you do that you can get very much noticeably more reach than with a 1Ds2 though.


(3) Peripheral AF sensor sensitivity and accuracy. Is it better than 40/50D ?


i think so although i have used the center point a lot more with all the bodies i've used

they are for sure way better than the 5D2 (speed, way less likely to hunt and miss) and especially 20D (in every way known to man) outer points


(4) Servo AF. Is it more like 40/50D or closer to 1DMkII(N) ? Or perhaps better than any of those ? (Honestly, I haven't used a Canon camera yet that would floor me with its Servo AF performance. That's where I need help more than anywhere else.)


not sure yet but it appears to be better than the 40D/50D

one shot is better, about on par with the 5D2 center point

haven't really given it the same sort of top level sports ai servo test yet

it will still have its missed shots though, especially when shooting 420mm and f/4 and DOF is razor thin and it's controlling a TC


(5) Low light FPS. What's the real scoop here ? If FPS is exposure sensitive, where does it kick back to a lower FPS and what would that FPS be ?


not sure

that seems almost weird on the face of it

the 7D has more reach and the 1D4 bigger frame to capture more light and crisper detail for birds that fill the frame

maybe the 7D AF doesnt handle distant birds as well?
he shoots mostly at the longer end so wants the better body used there?
