Alex » Really? great tip! thanks

Is there any drawback to doing this? I don’t want this lens to disintegrate in my hands

You can make it focus closer if you remove the big screw which limits the travel of the focus ring, remove the aperture pin and reverse the spring which normally keeps the diaphragm wide-open when pin is not pressed. My lens focuses now a bit closer than 2 meters.

Thanks Mike! It works for me too.

I’m having another issue though, I cannot use this lens anywhere besides f/2.8 – when I change aperture (stop it down a bit), camera overexposes. I understand what the problem is: canon camera / lens system has aperture open at max all the time, only when you click shutter it stops down and takes proper exposure. In my case, I have a manual aperture ring, I stop it down, but camera doesn’t understand that it’s stopped down. I might not be right, but there is a problem, something related to this.
