I sent in my 7D and 85mm f/1.8 lens 3 times now for front-focusing problem. A "supervisor" on the phone said that at f1.8 aperture, everything beyond about 6ft should be blurry because the lens is not designed to focus anything farther than that at f/1.8 and that if I wanted to shoot subjects farther away, I have to close down the aperture.

I could not believe what I was hearing from a "supervisor". I was speechless. I thought the lens could focus to infinity at any aperture. Am I wrong?

You are right. I don't know why they told you that.

Since it's an "ideal portrait lens" the 85/1.8 might be optimized for closer work. But it's not incapable of shots at further distances.

Why not MFA the lens?


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

Haha, that's what I thought. A nice guy though. I am getting a shipping label for the 4th time!

Why should I set MFA to +15 on a brand new camera/lens? Under florescent light, it back-focuses slightly now.

so they should have limited the option to +14 then

You shouldn't insult janitors like that.

This is when you should have ask to talk to someone who knew what they where doing !

I would send it back, without the camrea this time .

I just don't get how some companies can hire people who don't know what the hell they are doing.

I had a similar thing, sent a 85mm prime for calibration and I said it's soft @ wide open.

2 weeks later head technician calls me what the hell is soft @ wide 'angle'

I literally wtf'ed as the person that took and accepted my lens in for calibration apparently wrote 'angle' instead of open. :lol:

Here is another hilarious comment from the "supervisor".

When he first said that the lens can not focus anything beyond ~6ft at f/1.8, I told him that I have taken perfectly focused pictures of the moon with another camera at f/1.8. He then said that's different because there is nothing else but vacuum between my camera and the moon and that in my problem shots, there are 3 dimensional objects in the field of view.

I am not kidding. How do you even respond to that? But again, he was a nice guy so I just had to keep it inside.

Maybe the supervisor got mixed up between what is depth of field and focusing distance....
