Do anyone know whether the e1 wrist strap will fit the eos7d. If not, is there any accessory wrist strap available? I want to know before deciding... as I usually carry my cameras one-handed

something to share about the AF characteristics of the 7D that i have noticed after using it for about a month.
![]()
the AF points of the 7D cover a wider area than the square shows on the 7D (no AF point expension and no spot AF used).
The 7D also tends to focus on whatever is nearest to the camera. Hence, i have noticed that sometimes, even if one of the AF spots lights up as a positive confirmation, the area in focus can be somewhere slightly in front of the AF point (covered by the wider area).
to get around this, I use only the spot AF mode, not the regular square AF points. I will only use the zone AF/auto multi AF/AF expansion which only uses the normal square AF points when i am tracking moving items.
To be honest, the larger than usual AF coverage of each AF point irritates the hell out of me. but at least i can select spot AF for all the 19 points, so i can still use the 7D in the same way i use my 5D and have more "accurate" AF points.
This is where i miss the D700/300 number of AF points. although we may not need/use all 51 AF points, at least it means that each AF point will only AF within its specific square, not an area wider than the AF point.
Unpleasant is subjective; what if it was a very old person, the wrinkles and what have you might show more character in your subject.am i right to say sometimes it is not wise to hv an image that is too sharp??
if is too sharp for especially portrait shots, too many dark spots, marks and
wrinklers will be exposed and it would make the subject very unpleasant.
do you all agree? :think:

I suggest 7D owners with "problems" should give this a good read. It might help.
yup, which is why is why i suggest that most people with the so called "problems" just don't understand their equipment well enough before they start whining on the internet forums kekeke.
To verify single shot AF accuracy, one can activate the center SPOT AF point, mount camera on tripod, point camera at a target with high contrast (black/white) and carry out a series of half-presses.
If the distance scale on the lens moves all over the place, AF is inconsistent and this is unacceptable.
If AF is consistent, one can verify if contrast based live view focusing results in the same AF position as normal phase based AF. If they disagree consistently, one has a front or back focus.
There is NOTHING complicated about this. If one finds this hard to understand, then one shouldn't be using a DSLR in the first place.

Ok, I've gotten my 7D back and now they are working fine it seems. A senior technician called me up and we spoke on the phone with regards to my AF problem.
Apparently, they found nothing to be out of order with the camera. He admitted that the camera and its AF system is new, and his findings were according to a set of testing as prescribed by Canon, and there may be more things that they have yet to discover with regards to how the AF would function and behave under different condition.
We had a discussion on how my own 'test' was carried out, and what could have influenced the AF to behave the way it behaved, eg. low/high light, flickers of flourescent tubes, contrast of subjects, plane of focus, etc.
Anyway, to cut the long story short, they did some 'electrical adjustment' and updated my firmware to 1.10 for me, and I took the camera and lenses home. I've been shooting with it during a conference trip, and the AF seemed to be more accurate.
I repeated the same test with the same parameters and lighting condition, and found that I'd still get 1-2/10 shots slightly out of focus, but this time round, they appeared soft rather than a complete miss.
I'm quite happy with the results so far. I told them, I'd rather the problem be a user's one, rather than a manufacturing defect. The technician also laughingly said that more firmware updates and tweaks may still be on the way, and i'm not sure if he was joking or not....
Hi doodah, btw have canon fix your problem yet? what did they say about your AF problems? Maybe you can post what they told you to help some of the members having problems with their 7d.
Tested with 17-55 f/2.8 IS lens which works perfectly on my 450D body.
Initial problem was AF inconsistency + front focusing.
AF is now consistent and accurate at 55 mm. But it gets progressively inconsistent towards the wide end.
AF tests were carried out in the presence of technician himself. It's a straightforward, valid procedure that is consistent with Canon's specs.
Camera + lenses still at service center. Sigh. I will rather have a working camera than a rush job. But it MUST work accurately and consistently.
anyone exprienced a "freeze/busy" problem with their 7D? i just did last night when i turned it on and couldn't release the shutter and the lcd panel says busy... i had to remove the battery and put it back in to solve the problem. anybody knows what the cause of this problem?
