Sharp photo by 7D?


hakhtar

Recommended Posts

Perhaps those who promoted 7D would like to post any unprocessed photos to prove the 7D 'sharpness' - I have not

seen so much internet discussion about the focus problems related to one camera i.e. 7D.

 

I think 7D has focus problem by design and it does not need lab test conditions to prove this since other Canon

cameras don't need these sophisticated tests to prove that the photographers are at fault!

 

Without updating my camera habits or photo taking techniques or going through do this or do that, I had no focus

problem with my 500D and have no problems with 5Dll either!

<p><em>No, it does not.</em> It's capable of<em> fantastically</em> sharp images, used properly.</p>

<p>Husain, this nonsense has been bounced around the internet since the camera was released more than three years ago - do we<em> really</em> have to go over it all, all over again?</p>

<p>Maybe <em>yours </em>needs AFMA; maybe <em>yours </em>has a fault; maybe <em>you</em> need to understand that by definition, densely-packed, small-pixel sensors may need a different sharpening approach; and maybe <em>your</em> approach to evaluating sharpness is flawed.</p>

<p>But the 7D <em>does not</em> have a "focus problem" - it wouldn't be the world's most popular APS-C sport/wildlife camera if it couldn't focus and couldn't produce amazing sharpness.</p>

<p>I have to try really hard to get a out of focus image from my 7D. It's almost impossible unless I let the camera decide what it thinks the subject is (auto AF point selection). Love the spot AF feature for tele and macro. Here's a few where it "managed" to lock focus:</p>

David, why are so worked up and defensive - after all it is a camera forum.

 

Yes, I'm disappointed with 7D which I added to my 5Dll after reading so much about it here and believing in it simply to find that perhaps it was all promotional stuff - I have simply wasted my money and this forum is partly responsible for it! This is precisely why I'm here!

<p>I must say I greatly prefer my 5D2 over my 7D, but mainly because I love the huge VF and silky smooth images. However, save for the 5D2's center pt, 7D AF is a lot better, especially off-center, AI servo and low light. I recall struggling with 7D AF at first mainly because there were so many modes, sensitivity tweaks and, mostly, because it was so different than my prior cameras. Once I got used it, it was hard to not focus well. I assigned spot AF to the DOF button and can invoke it on the run without diddling the modes. Someday, when I grow up, I might buy a 5D3 as it sorta combines the best of the 5D2 and 7D into one camera.</p>

Puppy, this helps - frankly speaking I was hoping for guidance e.g. the best techniques to achieve good focus on 7D rather than being abused!

 

Still if there are some fair-minded users of 7D who could give me the benefit of their experiences regarding this matter, I will appreciate!

Husain,

 

It will help if you could provide a few samples of images you've taken and are dissatisfied with. Ideally, you'll want to

include the shutter speed, aperture, ISO setting, lens and focal length, whether you were using a tripod, whether it was

shot in jpg or raw, AF settings, and a description of any post-processing you've performed.

 

The good news is that, unless something odd happened to your camera, there almost assuredly is nothing wrong with it. Every time you change cameras you have to adapt. Sometimes the changes are small, sometimes they are quite large. For example, I had some issues when I moved from a 350D to a 40D, and it took me a few months to adapt. Similarly, I recently added a 5Dmkii to the stables, and had to modify my post-processing to include some additional tweaks my other cameras didn't need.

 

To quote Douglas Adams: "Don't Panic." There is a lot of experience in this forum, I'm sure we can get you an answer.

<p>If you are hoping for some guidance, and technique with a piece of equipment, it may be best to actually ask for some help & guidance. Your OP (in a nutshell) said: The 7D is a flawed camera, could somebody post some images to prove that it is capable of making sharp images? and "I have two other cameras with <em>completely different</em> AF systems and they work fine." implying you feel there is no flaw in your technique.</p>

<p>Frankly, you kind of asked for it. And all those whom would have given that advice freely are now offended because you bashed their equipment of choice</p>

<p>Perhaps, since the AF on your 5D2, and 500D works so well, you should get rid of your 7D, and buy a 50D. It's very nearly as fast, a bit noisier, and you won't have to adjust your technique at all, since it's AF is nearly identical to the 5D2 and 500D. You won't have to learn anything new!</p>

<p>If you wan't help and guidance on your 7D (OTOH), I would start by reading the manual - specifically the AF section, and then, perhaps the Magic Lantern guide on it.<br>

<p>Husain, why would anyone want to help you now. They give advise and you respond with</p>

<p>Puppy gives you what you asked for and you aren't satisfied. It must suck to be you- to be proven wrong, yet you still blame others<br>

<p>This is typical, Husain.</p>

<p>Some people populate the forums as their own social network. I won't say any more than its disappointing that you cop all this dismissive stuff.</p>

<p>Go onto the DPreview.com forum and ask the same question. There are three reasons why you get soft images: Technique, camera focus off, lens focus off. If you are unsure, send it in to Nikon to be checked with a image to illustrate your problem. There are variations in manufacturing QA.</p>

<p>You nmight want to familiarise yourself with what has gone before on this subject with Husain before pontificating in such a self-righteous manner, Francisco - I don't know why people like you feel the need to defend trolling, but I'd appreciate it if you would at least not do it from a position of ignorance. </p>

I posted a similar thing a little while back. The end result is i am still very happy with my setup but there are those that have definitely had issues.<br>

Within those 2 are links to other places for more opinions on the subject and for checking properly if there is an issue, also for fixes (like reseting the system, micro adjusting for a lens and conducting proper tests). You issue may be unrelated and due to factors other kind folks have mentioned, but if you still have some issues those links may be worth a whirl.</p>

<p>--- the links from within those links:</p>

<p>My problem with 7D's AF is in AI Servo mode with fast moving subjects. It has absolutely no problems with static subjects in single-shot mode. In AI Servo mode, shooting bursts, the AF will hunt around the focus. Shooting using 700mm of glass, this becomes and issue.</p>

<p>I bought a 5D MkIII a few months ago and its superior AF tripled my keeper rate. It's AF is quicker, more consistent and more accurate.</p>

<p>If you take enough images with the 7D, you'll get some really, really sharp ones, but the proportion is not as high as you'd want. The 1DX, 1D MkIV and 5D MkIII are all superior to the 7D in this regard by a wide margin.</p>

Dear Hussain, 7d is a master piece and

you should not be going wrong with it

check out your lenses they may be out of

calibration. I am using old nikon 50 mm

f1.2 on 7d and the focus pattern works

nice with me even I am doing it manually.

7d has all the features that we were

dreaming for long time.

<p>Keith,<br>

Keith, with respect, you betray your lack of impartiality. Yes, the 7D is a great camera and your portfolio is very impressive, but please be gentle with people who ask simple questions. You were one yourself once.<br>

The forum is not about you, nor is it a place to throw around your weight. And to use the word "troll" about our OP is offensive and betrays a lack of respect for your fellow man. You may or may not understand that legally, posting on a forum is akin to putting comments on the front page of the newspaper and exposes one to the relevant libel laws.<br>

Please be positive and informative. I detect some envy coming through your words when someone mentions the 5D3 and you immediately jump down peoples throats. Curious really.</p>

<p>Husain, there are others in this forum who are giving you valuable advice. Read their comments and if you need to have your camera checked, do so. It may only be a minor adjustment that's required.</p>

<p> </p>
