Canon EOS 70D & EOS 7D Mark II Speculation [CR1]

[Marsu42]

In my experience, and on this forum too, there is a minority who shoot slow, thinking that IS keeps the image sharp - and then wonder why their images are soft as they dont understand about motion blur.

And that's the way marketing wants it: You pay money for features and get immediate tack-sharp pictures.

Imho, basically man people don't have in mind that it's just "probabilities" that help to have a good keeper rate like IS, good af, high shutter speed but think that if you've got any single one of these you're bound to have 100% sharp keepers.

Btw, with a bit of training I don't think it's that hard to tell motion blur from out of focus in most cases.

He couldn't have understand how to use it or used cheap lens on it because for me I have had nothing but sharp images.

- keep the shutter speed high and use the factory defaults (except for using the AF expansion point)

Well, maybe not ALL of the reported focus problems you are blaiming on "user error", (which I admitted in a previous post) but I cannot help not notice that your answer to your "soft focus" problem on your own 7D, is to 'keep the shutter speed high'?? ??? And of course, I cannot help but notice that you blamed his "soft focus issue" on his lack of "understanding" of his 7D. Hmmm....

That is not a legitimate answer. That is in fact, a bandage to a problem. I bet if you sent your 7D to Canon they would find a problem. Forgive me but, I cannot always "keep my shutter speed high" to insure sharp images. Sometimes, I have to shoot "old school" and slow things down a bit. 8) And, when I do, I expect, super sharp images. Which of course, is what I get now that my 7D has been fixed by Canon. Don't believe me? Check out the photos I posted in a previous post to this thread.

Yes I do think the previous owner of my 7D did not understand - I have had nothing but sharp pictures from the camera. I have never had a soft focus issue with my 7D which you are now claiming I have - the previous owner did - but that WAS a user error.

So far you have accused me of saying:

- all focus problems can be blaimed on "user error"
- my 7D has a focus error which I am applying bandage to the problem

So two libellous accusations so far - any more?

LOL!!! No, I did not blame you that you said that ALL 7D focus issues are "user" error. Read my previous posts and you will see that for yourself!

And yes, I believe that if you have to shoot "fast shutter speeds" to achieve good photos with your 7D then YES, your camera has a problem. Which of course YOU said you had to DO to get sharp photos. Am I missing something? I simply quoted what you said... did I misunderstand? I am sorry otherwise... Or perhaps something else, or someone is to blame. :-X

My images are fantastic once Canon fixed my AF sensor. See proof above. Any questions? Really?

How about you show us some photos from your 7D before your purchase and then after? (because of your increased "understanding" of the 7D, your photos should be outstanding compared to his!) No? So how do we know for sure? Just wondering....

Yep there you go - missed the point again about shooting fast. Shooting fast means shooting fast enough to avoid motion blur and handshake.

For example with a 7D the rule of thumb for a lens with no IS is 1/ff equivalent focal length. ie for a 50mm lens this would be faster than 1/80th. However for some moving objects 1/80th is not fast enough to avoid motion blur eg dancers so you would have to increase the speed to cater for that - for dancers that might well be 1/250

The previous owner would take pictures like this at 1/50th because he relied on IS of his 18-55 kit lens to stop handshake but forgot the motion blur. The IS in this example would not make the slightest difference because the motion blur would still happen. If you dont 'shoot fast' then you will get blurred images.

Please stop insisting that my 7D has a focus problem - it doesn't

I shoot everything hald-held, in low light and full sun, whatever. It doesn't matter to me what you say without proof with photos, like I provided. Nice chatting with you. Glad you like your 7.

OK, 7D, no flash, ISO 800, 1/664 sec, f8 with Canon EF-s 60mm macro. HAND-HELD, NO IS! Fast? Not hardly for the ISO setting (AND f8!!) and NO flash and NO IS and hand held!

This is after the Canon repair of course.

[briansquibb]

I dont have a 'before' picture because there has never been anything wrong with it.

Here is an example from my last shoot with the 7D.

Camera Model: Canon EOS 7D
Image Date: 2012-05-19 10:49:13 +0100
Focal Length: 200.0mm
Aperture: f/9.0
Exposure Time: 0.0013 s (1/800)
ISO equiv: 250

IS on, panning mode - so shooting fast

Read my definition of shooting fast. IS would have no effect after 1/100 so that is hardly startling

 

[briansquibb]

I only use the 7D for sports so the lens are long so IS is needed - as in the example.

So you have seen my sharp picture are you now convinced my 7D is OK?

So IS is needed for sharp photos? (Now I am really confused) I used my 7 in low light were NO IS is possible (due to lens limitations, I.E. 60mm macro or 100mm macro) so no, I am not convinced, but whatever. My main point was to show the readers here that the focus issue of the 7D is REAL and that they SHOULD send their camera back to Canon if they have a problem and it is not up to you to tell them different. I only offer a second opinion on the matter, let the reader choose for themself what to do.

That's all.

If you had understood my definition of shooting fast you would have seen that shooting with a 200mm lens on a 7D would need a shutter speed of at least 1/320 for no IS. As I was panning and wanted motion blur for the bg then I turned the IS to panning mode so IS allowed motion in the horizontal plane whilst reducing vertical motion. So I was shooting handheld at 1/250 with a 200m lens - no big deal as this is what many sports photographers do

Use of IS does not indicate an error with the 7D. The picture demonstrates that my 7D is very sharp - I am disappointed that you dont accept that.

But I posted a sharp photo (hand-held) without the use of IS. (Attached with a Canon BG-E7 grip mind you...) I am likewise dissapointed that you cannot provide one. Oh well. Goodnight.

So the use of IS for slow pictures masks the 7D AF problem? That is an interesting - is this Canon's official line - use and IS lens anf the problem goes away?

Just curious, did you push the fill light on that file? It looks a little bright and noisy in the BG...

 

[jordanbstead]

When are people going to realize that IS doesn't matter above 1/125 if shooting with a lens 135mm or longer? If you're shooting at 1/800th, how would you even manage to blur a photo with camera shake? It's practically physically impossible.

If you are shooting at 200mm at 1/125 of a second? Yea, I think IS might be a huge help there! Not sure what you are getting at? If you are shooting at 1/8000 of a second, then I don't think IS would make a lick of difference, but under 1/1000 of a second? Depending on the focal length, and weight of the lens, IS can make a huge difference.

The general rule of thumb is your shutter speed should be at LEAST 1/focal length. So if you shoot a 200mm lens, your shutter should be at LEAST 1/200. If you really want to be safe, you should at least double that speed. That is why IS is so important.

Dont forget the crop, so on a crop a 200 it should be a minimum of 1/320.

When will people realize that IS is not only about reducing shutter speed? The main benefit for me is that it stabilizes the viewfinder, helping composition and enabling handheld hdr shots w/o too much difference between shots. And the most important thing at longer focal ranges: it helps tremendously to position the af point where I want it to be, so I'm getting many more keepers.
