Focus Issue

Wanna see the original? It's 3.22MB so you'll have to wait for a second.

Lens was a Quantary 28-300 3.5-5.6 AF.

I couldn't see any part of the photo the was really sharp. All the blades of grass see a little soft.

How sharp is your lense? I have a Vivitar manual zoom lense for my film camera that I couldn't get an acceptable sharp image from no matter what I tried.

Test your your lense to make sure it is sharp enough and use a tripod for slow shutter speeds. Some lenses perform better at certain apertures.

The rule of the thumb is to use the fraction of the lense lenth as the slowest shutter speed for hand holding a shot. For example if you are zoomed at 85mm then you should be using a minimum of 1/85 of a second and zomming to 300mm you should use 1/300. Don't forget that you need to calculate the effective focal length based on your senson size.

your 10d probly AF refocused when you snapped the pic after you recomposed your shot (after focusing by depressing the shutter half way.) on your 10D you can change the AF from the shutter button to the middle button on the upper-right back of the camera. in this way, you use your thumb to AF and your index finger to trip the shutter. i think it's CFn4 in the Functions part of your menu (but check your manual to make sure that's the one.) that's what i've done and my 10D soft-focus problems have nearly gone completely away.

Mike,

I'm certainly no expert in these matters but I'm a very curious so I luv to know what's going on. I was looking for the focal point but I think its as you describe in your post (the eyes). At first I too thought it apeared to be short focused. but I think that is an illusion. Look at the grass blades against the shoe soles vrs the black pants (butt).... no apparent diference in sharpness. I notice the lens is wide open 5.6 for this shot this will soften the focus a bit. I would just guess its the lens. Some just are not so sharp. Try stoping down even if it requires a tripod. Two bennefits... the lens will probably sharpen a bit and the DOF will cover all but the extreme background. Let us know what you decide. BTW. I looked for an online review for this lens and could not find one. How has this lens performed for you in the past...is there any tendancy for softness at wide open aperatures or any particular focal length?

Jeff, I hate to say, but yes, the faces are out of focus. The man's shoes look like they are sharp, but beyond that, at f/5.6, the rest wouldn't, and isn't in focus. My recommendation is to manually focus. The reason I say that is because I don't know about digital cameras and their digital focusing systems, and I don't want to give you or anybody else advice about something I don't know about. Anyways, I hope someone else has more advice about recalibration or whatever so you can use the autofocus. Good luck sir.

Mike:
If you look at the grass, you can see that the focus is in front of them. If you were in auto mode, the sys might have been responding to the brightest thing in the shot -- the highlight on the man's shoes. but the focus looks a bit nearer even than that.

Yep,......the reasinb for this...is because like mey you are using the EOS 10D.

The 10D is one hell of a P.O.S. camera....that frustraits me ALL the time.. Sometimes, I feel like taking them by their straps and swinging them as hard as I can....to make contact with a solid object...like a brick wall!!!

I see the flipping image soft in the view finder...and the "beep" in one shot mode confirms that it is in focus...so I hit the focus button again...and nothing happens... I still can see that it is soft... Now, when I am shooting sports... like in AO servo...,....say like my UW Whitewater FB game the other day in sunny light,... I was shooting into the shadows.....and up goes the receiver to make a catch in the end zone...and I am following the guy from the scrimmage line and I have thatfocus point right on top of his ass.......and I begin taking pictures..............click...click..click...and I preview the shots...hopeing that I made a killer photo...and the only phucken thing in focus in the picture is a photographer who is standing some 20 feet behind him...I lose my fricking marbles!! My 1n and 1nRS film bodies....heck, even my A2 bodies never had that problem!! ....NEVER!! Why is it that Canon built this 10D body with the AF points waaaaaay to damn large........si I can get clear shots of non action happening 20 god damn feet behind the players I am trying to focus on??!!

CRAP!! The 10D is CRAP!!!CRAP CRAP CRAP!!

CRAP!

Anyone interested in a pair of crappy cameras??

That "can" help...but unfortunately, the camera still s-u-x.....and the only fix for it...is buying something other than a 10D.

Today, I'm shooting with my Canon glass.
