Focus tuning.

After getting a k5iis and a da*60-250 i went off yesterday to try them out. now my panning techniques are not the best but even on static shots i was unimpressed with the sharpness or lack of it. so this morning decided to fine tune my lenses using this

Result was Da* 60-250 needed +5. samsung dxenon 100mm Macro was fine. Da* 55mm f1.4 needed +10. and Pentax F 28mm f2.8 needed +7.

I feel surprised that out of 4 lenses the only one that was spot on was not a Pentax, ( even if it is just a re badged Dfa 100mm) Is this unusual ???

Of course the one you found OK was a Pentax, being made by them in the same factories.

However, some people find a need to adjust lots of lenses. Some, like myself, have never found such a need. When I do, I'll run the appropriate tests and make adjustments. With a zoom it will be a compromise as it may differ at different focal lengths and distance settings.

Here are 3 after focus tuning and one without. Recropped and exposure adjusted, no sharpening. The last one was pre tuning
The difference is staggering.

Sorry all were shot handheld.

I particularly like the third shot, a really good composition.

If your pictures are now sharp, and they seem to be, then the job is done.

Thanks John.
