Heavy rain by Sunday lunchtime in Whitby.
Sporadic showers in Paris at the moment. K3&16-50mm + K5&50-135mm got drenched yesterday outside Notre Dame but both working fine.

A good rig. I also use a 293 at times.
Great results by the way.

Gary, in answer to your question, the apertures are down to inexperience. The shots with the Sigma 10-20 where on a tripod so I thought given the good light and shutter speed the smaller the better. What would I have gained using something like f8?
Diffraction at small apertures will cost you image sharpness Barrie. I have taken shots at very small apertures just for the hell of it but I generally will stop and consider DOF for most situations.Gary, in answer to your question, the apertures are down to inexperience.

The DOF of the 10-20mm at 12mm and at f/8 focus point at only 6M in front of the camera has a DOF of 0.7m to infinity. At f/5.6 (still at 6M focus point) it is 1m to infinity. Effectively so much DOF that at 10mm & f/4 if you focused on a subject at 2M the DOF is 0.7M to infinity.

Good images Barrie. Any criticism offered is as above with cropping and squareness.
My question; why such small apertures? Looking at the lenses used and apparent distance you shot from I would expect f/8 to be adequate to pull full DOF for these.
At times I do use a free basic DOF app on an iPod for certain shots. Such apps are probably available for smart phones as well.

I always fit a lens hood if the lens has one supplied or is available as an after market item.
