Tokina Super Wide Angle 12-24mm f/4 - DOF Question
"Dave" wrote in message ... Hey there, I was hoping to get testimonials about the Tokina lens' Depth Of Field abilities. I recently bought the Canon Super Wide 10-22 f/3.5 - 4.5 and I'm displeased with it's DOF abilities. I've tried shooting both with AF and MF, with varying small apertures, ISO's, ... and I'm just not getting what I need from this lens. It's a shame as the lens if performing quite well otherwise (barrel distortions, CAs, MTF Res, ...). I had posted a comparative (Sigma vs Canon) Wide Angle lens question a couple of weeks ago - to which I received a bunch of great replies - so I guess this is somewhat related. Thanks a lot, dave In what way are you "displeased with its DOF abilities"? Any lens of the same focal length and aperture used on the same format and in the same circumstances will give you the same depth of field. I have the Tokina 12-24 and it's great, its depth of field is great too, but at the same focal lengths etc. your Canon 10-22 would be exactly the same as far as DOF is concerned. Neil Neil |

Neil Neil When i said displeased by DOF performance I was referring to things are out of focus far away when using f8 - f13 with my Canon 10-22 lens. My other lenses (Canon 17-85, 70-300) are sharper both close up and far off - when using the same f-stops. I've learned a lot of things in this mail and I'll read up on all of them / try them out over the weekend. So I'm good now, thanks, dave |

Tokina Super Wide Angle 12-24mm f/4 - DOF Question
I have the Tokina 12-24 f/4. I have found that at f/11 or f/16 as David says
below to be the sharpest when focused as suggested. Steve "David J. Littleboy" wrote in message ... "Dave" wrote: I was hoping to get testimonials about the Tokina lens' Depth Of Field abilities.

It's a shame as the lens if performing quite well otherwise (barrel distortions, CAs, MTF Res, ...). DOF does not vary significantly with the lens quality (within reason). Your Canon lens is fine. If you want the maximum DOF in landscape work, turn off AF (set the lens to MF), set the focus distance on the lens to 1 meter, use f/16, and use the wide end of the range (16mm and wider). You should find that your images are sharp from quite close to infinity. You might prefer f/11 for sharpness, at which point you may want to stick to focal lengths closer to 10mm. David J.
