A "creation" by me? You give me too much credit.

I've steered clear of posting in this thread because I've already made my opinion of why you even started this thread. I've simply elected to not further fuel this nonsense. I would hope that someone who has actually read through everything (up to when I stopped posting) can see that I didn't "create" the 2ms.

I think that we are all starting to see the truth behind what is going on here. I guess that we can only hope that the thread will be locked soon.

Edit: As for pre-focus, isn't that the point?

Please reread my post. I wrote, "the idea of 2mS being noticed ". (I should have written "noticable'). The idea that one can tell the difference between two cameras that are 2ms apart is all yours. I never wrote about that, except to tell people that that wasn't what I wrote. Sorry, but it's true.

One thing you are right about is that this thread has become nonsense - due mostly to people who have limited experience with Canon camera bodies and who can't comprehend the effect of shutter lag, people who seem to be able to ignore the sage words of those who do have the experience. I find it amazing that a simple comment about the 7D could bring out the worst in so many. It seems I have somehow offend the truly righteous Canon fans. So be it. I'm done with this thread.

This has nothing to do with "righteous Canon fans." Never was an issue and never will be. This issue simply came down to one statement, deliberately noting only 1 set of data (the pre-focused shutter lag), to cite a particular camera manufacturer has taken a step backwards. It could've been Nikon, Sony, Olympus, Pentax, Leica (you get the point).

And when a set of data was looked up, 0.062s vs. 0.063s vs. 0.064s (as posted from Imaging-Resource.com), it was determined that indeed, the 7D pre-focus shutter-lag was slower. But by 0.002s (compared to the other APS-C cameras in ITS line-up). I didn't create the numbers. I simply looked up what the fuss was about. Looking for rhyme/reason why someone, who used to quote himself in his signature (as I see no longer), would claim any manufacturer taking a step backwards with their latest camera model.

From where I sit, sifting through your posts in this thread, it is clear to *me* (and probably me only) that you enjoy being controversial. This is nothing but a mere game that you like to play. You could've simply acknowledge the fact looking at the overall 7D package, this particular camera has taken huge steps (relatively speaking) in the right direction --- improvements. And although I'm sure other things will surface (likely more noise-reduction blurring, red channel issues, etc...), overall, the 7D is an improvement over existing APS-C line-up for Canon.

Yet, for your own entertainment and playing your own game, you wanted to focus on "0.064s" as "a bit of a step backwards for action shooters".

I didn't create the numbers. I merely made it known for other readers in this thread. IMO, you got exactly what you were looking for by posting this thread (not meant as a bad comment). You got your excitement, your own personal mental/psychological thrill. Kudos.

At this point, I think that what you said is pretty clear to everyone following this thread.

When I find such a disagreeable forum member, what I like to do is go back and look through the last page or so of topics that they've started. Sometimes, I think that you will find that a particular user is generally someone good to talk to who may just be having a bad day. Other times, however, I'm afraid that you find that a particular user seldom, if ever, posts anything worthwhile, and seemingly lives to post for their own amusement and gratification.

I believe that it is these people for whom the ignore list was created. ;)

Haha, it's quite possible then that I've made a few ignore lists myself.

That said, there comes a time that I draw the line and simply accept the fact that we're all different individuals and have different opinions. It's the beauty of being human. Even though I feel that a difference of 0.002s is negligible for camera shutter-lag, I have to accept the possibility that someone might view that as completely unacceptable. And in such an instance, my opinion differs from theirs but it doesn't make me wrong and them right.

It's the reason why I stayed away from further postings in this thread until Ian had brought up my name 2x recently. I don't think ill of him, and from the responses I've read from him, I believe him to be highly intelligent. We just differ in opinion and that's fine by me. :)

To paraphrase a good friend of mine:-

By design, POTN is one of the friendliest photography forums on the internet. This is no accident; we work very hard at.

Unfortunately, there appears to be an inherent lack of civility in some people that precludes them from discussing things without doing their best to introduce friction into the conversation. After all these years, I've never figured out what makes them do that, but whatever their reasons, it is distracting, unnecessary, and downright rude.

Sarcasm and verbal gotchas serve no purpose but to make people look pathetic. .

Some of you need to get a life.

The subject of this thread is extremely tight, and to many people, it's largely irrelevant.

If you have something constructive to add to the discussion, then do so. If you have nothing to add except for personal attacks or derision, then it's probably best if you simply say nothing and leave the thread alone.

XterraJohn, this wasn't aimed at you alone. If people persist in these negative comments, then they may find their posting ability severely hampered.

My apologies. I don't think that I intended to come across as posting negative comments with no constructive value.

.064s

That puts it about even with the 30D in terms of shutter responsiveness and slower than the 40/50D. So, a bit of a step backwards for action shooters in this respect.

Note: D300 shutter lag time = .045s, which puts it in the same league as the 1DmkII/1DmkIIn...

The Digital Picture's table currently states a different spec:

59ms for the 7d - this is the same spec as the 40 and 50d, and much faster than the 5D Mark II at 73ms.

http://www.the-digital-picture.com …al-SLR-Camera-Review.aspx (external link)

You will have to scroll down almost halfway down the page to find this comparison table.

The only canon cameras that beat it are the 1D series, which are, according to this table, 40-55 - meaning that potentially, the 1D series as well might not be a huge magnitude faster than the 7D in this regard, and certainly, that the 7D has the fastest shutter lag time out of an EOS camera other than the 1D Series cameras.

These, of course, are raw specs. I know you were citing the Imaging Resource as the source of this info, but they also stated that the 50D's was a (practically) equal .63 ms vs the 7D's .65ms. It's worth noting that the D300 test also states the shutter lag as being slower than your claim @ 57ms, and the 1D Mark III is coming in at 54ms.

I don't think this camera will perform out of spec compared to other Canon's. Maybe not up to Nikons as you state, but certainly very good.

Well, after owning a 7d (for over a year) and putting up with the shutter lag, I finally sold it and bought a 1DmkIII. Much better. :)
