That is an awesome amount of work Jimmy. Very comprehensive and very well done. One can certainly see the well documented fall-off of resolution due to diffraction at smaller apertures and high ISO's.

Thanks for putting so much effort into that work. It was obviously a herculean effort.

Now that you have your TZ30 totally characterized, you need to go out and get us some scenes of the Scottish countryside with it. Those picture serial numbers are awful low!!

Thanks again,


Thanks very much for your very complimentary remarks. It is great to hear that my efforts are appreciated and that I have been successful in presenting my findings clearly.

With regard to your comment about the serial numbers of my test images being awful low, I guess I need to get out more.

On a more serious note I suspect that is partly due to my having too many other interests and commitments and partly to many years of being limited to two or three 36 exposure cassettes of colour slide film during two week vacations in my pre-digital years. I guess that in my case old habits die hard.
