Sorry title should be, "Big aperture but don't want shallow DOF". Mod if got time can help me change? Thanks!!

I have this question. Recently borrowed a friend's 50mm F1.2 lens and found that it is extremely helpful on high shutter speed and handheld night shots. However DOF is very shallow. How do I use such lens but with deeper DOF?

Appreciate your help! Thanks!!

beside from taking the picture of the same subject from a further distant, I don't think has any method you can increase the depth of field.
agree... nothing else

Want more DOF? Use a smaller aperture and mount your camera on a tripod if neccessary. Some effort has to be spent to achieve a good picture.

You can reduce the aperture and shoot at higher ISO. ;)

But DOF and aperture are directly related. The only variable you can use here is ISO.

simple, get a tripod and extend the exposure while stopping down

in case you guys didn't read properly.
TS want to shoot hand held at night with high shutter speed, but also want more depth of field.

let me see.......:think:
think the better answer is upgrade to a better camera able to handle high ISO...

get a Nikon D3

also depends on what he is shooting.. if he says he's taking humans i can understand

if he end up saying he want to take clarke quay reflections, then much better to use tripod no matter what :dunno:

I wanted to post.. but couldn't think of a good solution yet.. Need to know what TS wants exactly but I can't seem to decipher. For myself, I would only go for a fast lens because I want selective focus from the shallow DoF. I'm stumped!!

check out TS another thread, he want to shoot ghosts,
bear in mind that ghosts are very hard to focus, so need more DoF. :bsmilie: :bsmilie: :bsmilie:

Even then.. you'd not be focusing so close that the DoF becomes so shallow. Yes, I agree that the DoF for 50/1.2 is razor thin but it's not that thin anymore when you focus far away. Stopping to f/1.4 increases the DoF by quite a lot and even more at f/2. The most only lose a stop. Bump up the ISO by a stop and it should be fine.. :dunno:

oh dear.

he needs infrared.. ghosts appear better in infrared, i hear. :bsmilie: just kidding.

so don't want the ghost to be in bokeh, huh

yes, i know, but if you shoot landscapes at f/1.4 you are going to be getting soft landscape images. most 1.4/2/1.2 lenses are not at their sharpest at all at extreme wide open apertures

Yeah.. but that's spherical abberation problem.. not DoF problem.. ;p Nice mah.. soft soft dreamy dreamy nightscape. ;p
