p.3 #1 · Mark III blur frustration

What a waste of Fred Miranda...to the OP, David had it 100% correct when he typed "Perhaps a book on digital photography might be in order here."

That really should have been the end of this discussion. Why these discussions turn into personal insults is beyond me...

I agree with David (dhphoto). There is some sort of lack of understanding here.

Take the camera out in the daylight. AV mode F 4.0 - 8.0 Make sure the shutter speed is above the focal length of the lens.

Snap some pictures. You don't need a tripod or remote to do some basic tests.

I know, it's really sad.

This is such a great site and 'people' come along and spoil it for everyone.

Sometimes I react when I shouldn't, but it's hard not to under provocation.

It's depressing what passes for 'professional photography' these days.

I tend to agree with Petkal (let's take a step back) and dhphoto (book on photography).

One other issue that we may be overlooking is that the Op was using AIServo on what looks to be a static subject. Which is not a crime at all, but depending on how it was implemented, ie. back button or shutter button, the focus may have locked on the leaves, the pic slightly recomposed or the subject moved a bit and then ...boom...OOF subject. Frankly, all that points back to being familiar with the equipment.

I have no problem getting tack sharp photos in 2.0- 2.8.

Let's see them then - as David says (and as the physics dictates) you should be getting sharper shots at smaller apertures, not larger apertures, all other things being equal.

What are you disagreeing with me about exactly, it isn't clear.

I think that most of us believe the problem here is with focus point placement rather than with the shutter speed, Alistair...

C'mon Dhphoto,
Let's be nice, and not act like we're at DPreview...
I gotta admit, though I feel I know my 1d Mark III pretty well,
I still have never posted an image in either FM, DPr, etc...
I too am/was quite computer illiterate...
But that doesn't stop me from getting a few good surfpix almost every day...
Try to be nicer Dave,
Thanks,

Tell you what Randy, 10 posts in two years doesn't seem to show you've been helping people out much, so don't throw stones in a glass house, pal.

Tell you what, from now on you guys can help out, I'm done here.

Hi Alyce

I am not going to try to tell you what you did wrong because I am not positive what you actually did from your explanation.

You mentioned a few times that " She was the center of the original photo. I cropped it to thirds on my computer later."

Does this mean you manuallly selected a Focus point that was on the girl her or did you just compose the photo with the her in the middle of the frame? Maybe this is the cause of the confusion.

Some of the folks here have asked the question what were you focused on

Forgive me if you already did this, but did you Manually select the Focus point or did you have the camera figure out what to focus on. If you have the little girl in the center of your frame doesn't mean the camera will automatically select her as the main thing to focus on.

You have different areas of contrast in the photo and the camera will pick out the highest contrast area in most cases. You shouldn't rely on the camera to decide what the best focus point is; you should select your own focus point whenever possible.

Also, since you are shooting a still subject then I would suggest to switch from AI Servo to One Shot mode because you will get a focus lock beep (and focus light indication) that helps as an indicator that the subject is actually in focus.

I wont touch on the 1/50 Shutter speed that will affect getting a sharp photo also. Since there was an area in the photo that was actually more in focus than the actual girl then the issue seems to be more related to the Focus point selection.

This is a MKIII camera? Have you done a proper Auto Focus Micro Adjustment for this lens?. Do that and then see how well it performs.

A little over-reactionary, David, don't you think?

For those having an issue with David's tone, I may be new to FM, but I've been around enough to know that sometimes David can come off as being a little terse, but the guy knows his s**t and does not suffer fools gladly. I really think that is all which needs to be said on that.

Anyways, I took a look at the OP's website, and there are a lot of correctly-focused and exposed shots, but there are a few where is subject is either inside the MFD of the lens, or the focus is simply incorrect.

My inclination on this photo is to say, like others, the leaves in the background are in focus. If this was truly an AF not MF shot like the OP claims, then:

1) There is a horrible "back focus" issue with the camera and/or lens

2) An AF point which is not the center point was selected

As any professional portrait photog would do, I am assuming the OP shot this in RAW, so why don't you open this photo in DPP, enable AF point selection, screen capture that, and post back so we can all concretely and accurately see where the camera truly AF'd?

Gosh Dave,
Don't get so mad...

"Tell you what Randy, 10 posts in two years doesn't seem to show you've been helping people out much, so don't throw stones in a glass house, pal.

Hi Dave,
No reason for the personal attack bro!
FYI, I luv taking surfpix here in Los Angeles. I also run a surfshop in Santa Monica,California at the location where "DogTown" and the old Zephyr surfshop was...It's kinda famous, goggle it, you'll know some of my history...
Anyways, bro, I was just commenting on what I felt was a negative attack on someone who might be a "pro", but a beginning one at that...
Kinda funny, the other day, my longtime neighbor who has his studio here in Santa Monica right next to the surfshop noticed my 600mm lens as I headed to the beach. He comented on the fact that if I was shooting photo's now, I was going to put him outta business!
I had laugh with him, he is a very well known and respected American artist/photographer named John Baldessari and me, though I too am somewhat of a "pro", ok -"a beginning pro", well I pale in comparrision to him, only wanting to keep taking surfpix and have a good time doing it!
I, along with many others I am sure, browse FM, DPreview, Potn,SS.com, etc...
I feel that I learn alot from ALL the many photographers who share their EXPERIENCE with others, it is like one big classroom to learn from. Even though I rarely, if ever post, like you stated some 10 posts over a few years, I read and learn daily, so thanks for posting and contributing, bro...
But can you lay off the personal attacks?
Thanks,
Randy in Los Angeles

I don't know everyone...this post really speaks a lot about the way this forum in general is going...

I think to most it is obvious that the OP's problem is really a problem with not understanding how the equipment works. This was stated by several posters, and others offered some very good advice on alternative theories of what went wrong in the shot.

Why we have all this name calling and personal attacks is really beyond me. Is that what we really want to be discussing?

Let's boil this down...the OP shot a bad picture...the reason...they didn't understand how the AF was going to react given the situation. They are not stupid...we have all done something like it before. Nor is anyone else stupid or mean for pointing it out to the OP

Eveyone else should get along so we can all grow from these experiences...otherwise don't contribute!

Enough of my soapbox...Robbie

Hey David,

Seems like I'm not the only one that noticed. I've always enjoyed your comments and insight, like most of the other folks. Maybe it's just a bad day. Please, no hard feelings.

Never mind, everyone. I believe I've figured out the problem. I had a shoot this morning and the photos are great. Many of you helped me by pointing out possible solutions . As I first suspected, it was a simple matter of something that I had overlooked. My Mark III is new, so I'm guessing there are bound to be a few problems while I get used to it. Unfortunately, I will probably avoid coming here for help in the future. Somehow a photography question turned into a personal war. That is a shame.

Thanks to everyone who truly responded to help.

I did not say that.

I am merely saying that not everyone is sugar and honey on any forum, and each person's personal approach must be taken in context.

We are still waiting for the OP to fill us all in on exactly what the issue was, and given that, some of the more "direct" replies to the OP are not entirely off-base.

With the incredibly vague information the OP has given, this is starting to smack a little of something from "Kanon Kid", if any of you remember that debacle.

So, AlyceNWndrLnd, as wing tong has asked, what exactly was the issue?
