Re: Tokina 11-16 has never felt sharp compared to my other lenses
 

Guys thanks so much for the pointers. I have a shoot coming up so I will do some tests at f4. I have heard about a "sweet spot" for apperture and focus so I won't give up on this lense just yet.

what is the recommended 'sweet spot' settings using the tokina, for a general wide shot then?

Not sure if its poor form to link other forums but I found some info here:

I've read up on this lens and another issue that has come up is the codec. Looks like this lens resolves more details that the H.264 codec is able to handle. If you have any experience with the codec that the gh camera's use, you know that under very detailed scenes like foliage outdoors or grass, the image will deteriorate because the codec cannot compress the information.

great links there Stephen - thanks for that.

This is an interesting point. There have been a few times where things have looked nice through the view finder only to look a little disappointing on my Mac.

Stephen, I assumed that the feed to the viewfinder was compressed? Maybe your right though, I don't know.

I guess the real test would be some simple indoor test, with not a lot of stuff going on, compared to an outdoor shoot with a lot of information.

I think the think about the viewfinder is being a small screen things would look sharper anyway. I have done a couple of test since starting this thread and shooting with the apperture a few stops in from either fully closed or wide open make a big difference.

This footage (sans the flag shot) was shot with the Tokina 11-16, albeit with the 60D (I know this is a 7D thread, my apologies; the two cameras shoot the same footage though). Never really had focus issues unless I was shooting wide open, which is to be expected with high apertures.
