Does anyone have their own aperture sharpness chart for this lens they could throw up?

I will give it a shot.

Thanks! Looking forward to seeing your graph.

You get a curve like that when you have a decentered lens element.  Exchange it, or have it repaired.

That's what I was thinking too.

Even with the new chart I've posted it still looks like a decentered element to you?

Thanks for the response.

I had the exact same thing with my first copy of this lens. I did return mine and got a better copy the 2nd time.

Exact same thing as in what the new chart looks like?

So I noticed that for some reason my exposure compensation was activated when I did my initial test.


This is what I got with everything set properly on the camera. Is it still normal to see dips like this, even at f/5.6?

Thank you very much, Mt. Spokane.

Again, my nerves are a bit calmer now. It's stressful to worry about a recently purchased $2000 lens damaged by user stupidity.

The scratches won't affect dust and weather sealing in the future will they?

Lenses / Scratches on inner barrel of lens
« on: October 05, 2013, 06:12:29 PM »
I had a hair that was stuck in between the outer and inner barrel of my new 24-70 f/2.8 II. Trying to remove it with my finger proved insufficient. I got some tweezers and managed to grab the hair and pull it out.

However, using the tweezers I noticed I made some very small (tiny) scratches on the inner lens barrel.

Is this cause for concern now or down the road?

Thanks for the responses. My lens only had a slight bump. I don't think it was hard enough to do any damage. This thread was more about the durability Canon L lenses. I still will test my own lens though, just to be on the safe side.

I'm just wondering how much these lens can stand up to without damaging anything internally. Has anyone here had any mishaps?

I was on a power boat the other day and I was leaning over the side when a bounce caused my to slightly ding the bottom of the barrel against passenger side windshield. Everything seemed to work okay afterwards, but it got me thinking/worrying about possible damage or misalignment of elements.

I love this little lens. I use it for street photography all the time. Once I AFMA'd it, the focus has been dead on.

It is a known problem. I have three genuine Canon batteries and my 5D3 only recognizes one as authentic.
