I am having issues wit the sharpness of my 70D. I have yet to be able to take a truly sharp photo

Hello there,

I was hoping someone could help me with a problem that I am having with my 70D. I have had my camera for almost 6 months now and I have yet to be able to take a truly sharp photo with my camera in ANY kind of automatic mode. The ones I would consider passable where ones that I had to manually focus and even then there is only a 50/50 chace that I'll get any that I truely like.

My lens of choice is the 100-400L IS and yes I do know that with this lens I have to contend with camera shake. I almost always shoot hand held and I do know that  shooting this way it is much harder to get  shots that are in focus and I almost always shoot in Manual.

I have set the camera up to use the Center Point Focus and I have noticed that it will very rarely focus on that point. For example I will focus on the eye of a bird and the back of the head will be in moderate focus and the eye will be soft or blurry.

I previously had a T2i and I was getting wonderful results with that camera and I was so excited to get the 70D and see what I could accomplish with it. I have been really disappointed in the results so far.

I have no idea what I'm doing wrong with this camera and any help would be appreciated.

Examples below:

Image below was take with my T2i a few years ago and I'm very happy with this image.  400m at 1/1600 f/10  ISO 400. Slightly cropped. Taken on a bright, very sunny day. I was sitting on the ground and had the lens stabalized on my knees.

Image below was taken with my 70D yesterday. Not so happy with this one. This image is an example of the image quality I get with this camera. Taken on a very bright, sunny day. This bird was slightly closer to me me than the one above. I was also sitting on the ground and had the lens stabalized on my knees. Not cropped. Straight out of the camera. 400m at 1/1000  f/7.1 with ISO 200.

Any help on what I am doing wrong would be most appreciated. I really am having quite a time trying to get good phots with this camera. I wanted something better than just snapshot quality.

If anything, I like the 70D image better. The other one looks a bit oversharpened to me.

 

Unlike the T2i, your 70D has autofocus microadjustment capability. Be sure to calibrate your lens if you haven't already done so.

Thank you very much for your reply.

The first image with the T2i is straight out of the camera. There was no sharpining done on the image, only a slight cropping. If you were to blow up the image you can see that the eye and feathers are in perfect sharpness and makes for a beautiful large image.

The one out of the 70D looks fine in the small image that they let me upload but, if you were to blow it up there really isn't any sharpness at all in eye area and feathers. Very soft and blurry and I would not be able to print this in anything larger than an 8 x 10. This is very distressing to me as large images are my staple.

As to calibrating my lens to the camera I have done so and this doesn't seem to help.

Thank you again for your help.

 

First and foremost, you can never compare two photos taken with different settings and cameras.  Even if the same lens is used on each. You will have to do a controlled test that eliminates all the varibles, including yourself.

I notice on photo was at f7 and the other at f10.  That alone makes a legitmate comparison impossibile.  The fact you were hand holding also makes it impossible.  And you said the distance wasn't the same.  See a pattern here?  No, becuae there isn't one.

 

Whether you do your sharpening in post or in the camera, it is done.  You should switch to RAW and do all sharpening in post. Leave the jpg for your cell phone.

 

I realize you can't make a good judgement the way you are trying to, but I undestand you can get a notion that something is wrong.  The camera can't misfocus from the center point by itself.  (Unless there is a malfunction that is.)

That has to be you.  When you pressed the shutter button, that is where you had it.

 

Do you controlled test and convince yourself, right or wrong but "correctly"!  The two cameras should produce very similar results.  They are very close to each other spec wise.

The 70D photo was using AI Servo; possibly not the best choice for a seemingly static bird (or at least moving across frame).

 

Also. focus point was basically off the subject.

Thank you so very much Mr. Hoffman!

That was the information that I was looking for. Thank you so very much for your time in looking into my problem and answering my question.

Now I know what the answer is and can fix it!

Indeed, the AF point is on the background, which is extremely unsharp. Doesn't this suggest that a manual adjustment was made after focus was achieved?

He does catch the edge of the bird. I tried with my camera and it doesn't take much of the subject in the focus rectangle to get a lock.  Focus mode was AI Servo. I tried to manual focus with AI-S to change where sharp focus was and the lens goes crazy since it is always trying to focus using the selected point.

 

I consider the right side of the bird to be OK. I think if the focus was Single Shot and the focus point was on the eye it would be a fine shot.

Thank you again Mr Hoffman for your comments.

 

I'm having a similar issue with my camera. ... Curious, using the bird photo as an example, what if you wanted the entire photo to be sharp, (the bird and the background). What would you change in settings? ... I tend to shoot everything in Auto, I'm still learning. Normally I take pictures of my kids, but even when they are standing still it seems like something is out of focus. I took a picture the other day of a bunch of girls at a table for a birthday party, the girls in front were in focus and the girls in back were very blurry. I took numerous pictures trying to capture the best shot, but someone was always blurry.
