Super Takumar 1:3.5/135 lens dof

Arcane · 04-09-2013, 10:43 AM

ok so i just got the super takumar 1:3.5/135 lens and i am confused as i see other people using it for filming and close up photographs but when i take pictures with it, it only does really shallow dof macro shots. I know its an incredible lens and i just think im not using it right i am kind of new to the whole photography thing but i do know my stuff... please help. oh btw i use a Canon 500D ive attached some pictures to show you the shallowness.

Guess we need to start with a basic question. Are you stopping down the lens at all, and are you making use of the A/M switch?

Arcane · 04-09-2013, 11:43 AM

Yup ive tried that sorry i wasnt clear enough is there a way of getting the dof less shallow without decreasing the aperture or is that the only way... is there a way to compensate for the light without having to increase the exposure time

and i have looked at the A/M switch but im puzzled as to what it does

The only way is it stop down or shoot stuff that's far away.

Take the 500D off the lens and it will focus normally (assuming it isn't broken). Right now it's working exactly as it is supposed with a diopter stuck on the end of it.

On some m42 mount cameras the A/M switch allowed the camera to stop down the lens aperture when the shutter tripped, as opposed to having to stop it down manually before the shot. Depending on what camera you're using it on it may not matter which position you have the switch in.

You said you were using a Canon 500D, that's a diopter (close up filter) to make a lens shoot closeup (macro) shots. Take it off the end of the lens. If there is in fact no closeup filter on the lens and you are using a Canon 500D camera (sorry, I'm not up on Canon nomenclature) then either the lens or the lens adapter or the camera itself may be defective if the lens won't focus to infinity.

A picture of what you are shooting with would be very helpful in diagnosing the issues you are having.

haha sorry yeh im using the camera canon eos 500d not the filter. its just lets say that im focusing it, it wont focus to the end of the room its just blurry it doesnt focus the whole way. i have to move forward into the focus area which is suprisingly short, however when i turn the aperture of the lens down it becomes less of a blurry picture and focuses a bit more
