All the way down to 18 on the 17-55 is going to start to get into the area where diffraction starts to show up, that is why I was asking. What need did you have for a long exposure? At that distance you should be hyperfocal at just about any aperture.

Some days ago, I did a little project. Put the camera on a tripod and shot the same scene with different aperture and focal lengths.

From the 18mm focal length:

The overall sharpest is f11.

Tied for 2nd f8 and f16

Fourth f22

Fifth f5.6

Sixth f4.0

Last f3.5

The Overall FOV:

Also, Makis, I think you should check this review out, here's the resolution chart from it:

Keyan, how about next time I go to the Grand Canyon I will make sure and consult with you on what settings I should use. I apologize to you and everyone for even considering to post the photo shown below. It clearly was shot using the wrong aperture with the wrong shutter speed.

Tod, don't take it that seriously, I think he was just trying to help.

Makis..nice test. Were you MFing using LV or using AF?

Thank you. It's been informative...

AF for the first shot in each focal length (tried a few times until there was no AF action/adjustment) and then turned to MF, so that it would not refocus in each aperture.

To be perfectly honest, I have never used Live View for better focus So I am not confident on how I would do. Given that the bridge is so far, I think I'd be hyperfocal in any aperture and I was always focusing wide open.

Tod, if I offended you, I'm sorry. I was genuinely just interested in why you picked the settings you did, I'm always looking to learn off people. And I was just trying to help out with the chart and link, apologies.


I'm terrible at making PP decisions, so I'll just keep em both!

Absolutely nothing you said and no apology needed...very nice weathered barn shot btw.

Good photo and as you already know, nothing wrong with F/18 at all.
