The bird shot looks to be heavily front focusing on the nearest part of the branch.

Try taking a photo of some roof tiles (full roof) focusing on the middle tiles and see if it's the tiles in front that are in focus.

To prove it would involve the complicated business of taking TWO SHOTS one at say 640 ISO and one and 800 ISO and comparing them ...... Far too difficult for a Pentaxian they prefer to waffle on about it This would be good for about 40 pages of waffle on the US forum.

I did post the results of a test I did sometime back on a K-5, but can't find the files.

It's also mentioned in camera reviews. Anyone who knows how to use a camera knows that you should stick to 100/200/400/800/1600 ISO because generally the noise from 500 and 640 ISO is the same as 800 ISO...... I thought even Canon users would know that

Carrific! Third one for me.

A DA*300mm f/4 + the Pentax-F 1.7x Adapter will give you 510mm f/6.3. It indicates the correct aperture to the camera. Image is bigger than the 1.4x TC and just as sharp.

The Sigma 150-500mm should be sharp What's important with these long lenses is holding them steady and getting the focus spot on. The Sigma has the advantage of in lens SR which works on a tripod. It should beat a 300mm + TC. Even a tripod won't hold a 500mm lens very steady. Sharpening is also important.

Test shot Sigma 150-500mm at f/8 500mm on k-5 400ISO tripod SR ON
100% crop from JPG slight sharpening in Zoner. Distance about 50m. It's harder to hold a 500mm lens steady on longer distances.

It's nice to hear that Canon users are as daft as us!

The answer lies within

It's allowable if you buy from a dealer that still gives Green Shield Stamps and you burn the books of stamps in a wood burning fire
