controlling depth of field
on Feb 29, 2012 at 11:26:26 pm

I'm using the Canon T2i to shoot interviews, and I like to use a (f1.8) 50mm prime lens to get the background out of focus. Currently I'm using a legacy FD lens with an Zykor adapter, but I find that I have zero control then over the aperture. I think it just operates wide open, and the depth of field is actually too shallow for me.
Am I missing something? Is there a way so stop it down to get more DoF, or do I have to spring for the EF lens to get all the functionality?

Thanks,

You would be better of using , say a 28-135mm f3.5-5.6 IS Canon Lens and no adapters,at say 85mm or 135mm or an EF l series f2.8 25-70 mm Lens at say 70 mm.


GOOD LUCK !

Thanks Bob!
Unfortunately, most of the locations I find myself in don't have enough room to use the longer lenses. The 50mm works most of the time, and gives me a plenty shallow DOF. (sometimes too shallow, as I mentioned) As for the DF lens, I'm just being cheap about it - the adapter was only $20, while the EF lens is around $100.

I found the answer.
The adapter has to be all the way in the locked position, or the aperture won't fire.
