No tripod, hand held with onboard flash, which is why the lighting is a bit harsh on some of them.
1 shot pictures, no stacking .. think they were all around F/16.
I was going to get rid of the Tamron in favour of the Vivitar but to be honest the Vivitar is made completely of metal and add that to the weight of the K10D which is a heavy beast to start with then it becomes quite uncomfortable holding it still for even a short amount of time.
The reason for the exif data is that the Pentax has built in shake reduction so when you add a manual focus lens you have to input the focal length. the nearest to 90mm is 85mm on the camera and the 135mm was the 90mm with the 1.4X teleconverter on, which again was as near as I could get on the camera.
Anyway, thanks for the comments
