  • 7) Pentax FA Macro 200/4
  • I am using it with the DA* 300/4, but it works perfect with other lenses too, like the F100/2,8 macro. I am sure it will work perfectly with your lens. Compare prices. Maybe you get it for a ...
  • I have bought a K3 some weeks ago, too. I got it with the DA 16-85 WR, for a good price (1100€) I have been using a K5, and I am happy to have got much better AF (quicker and the problem in warm ...
  • Great photos, and an beautiful place. I will have to get there, on of these days. Cheers - Klaus
  • Replied in Plant hopper .
    Hi Interesting species, and a good photo. It has some similarities with this Metcalfa pruinosa: An old photo, made with K10D, with too ...
  • Hi I had some old lenses with the stop of the distance ring not well adjusted. Sounds like this is the case. It is possible to adjust. In case of the lenses I know there were screws below the gum ...
  • An option to consider for old Tele lenses is the 1.7x Autofocussing TC from Pentax. I have used it with the DA*300/4 while the new 1.4x TC was not available. It works fine, and has good IQ at ...
  • Thank's for telling your experience. If KP price does not go down, or appears another crop camera, I will consider this one. Cheers - Klaus
  • In the first photo, taken without astrotracer, it can be seen that the lines that the stars produce are not circular around a common centre (what would be their real movement).   It is obvious ...
  • Yes, that may well be the explanation. I think you are right. I suppose that this lens is not bad enough to produce by itself these errors in the corners, without that combined effect of distortion ...
  • As the trails a radial, and not circular around the centre of the image, I don't think that they have anything to do with the apparent movement of the stars (due to earth rotation). The angle ...
  • My F 100 /2.8 Macro focusses correctly with my K5. l Best regards Klaus
  • what a shame. He knows a lot about flash photography. And was always very polite…
  • Replied in Brandrx (Ron)
    No doubt. you are absolutely right. Very sad that Ron is not with us any more. I liked the way he was seeing and doing things. Best regards Klaus
  • Hi Antonio That is a really extraordinary photo. Nice that diptero on the wings. Hasta pronto Klaus
  • To me it looks pretty good. Focus seems to be on the leaves of the trees a bit in front of the bird. But the animal has quite good detail, too. Not perfect because of focussing in front, but good ...
  • Hi Jonathan Really very interesting your explanation of these techniques. The photo of the glass recipient is great. Best regards Klaus
  • Thank you, Miles :-) Here how I prepared the slide holder (using things I had)
  • It is not absolutely necessary. You can fix the camera directly on a support, and as the distance will be se same for copying 24x36 mm slides or negatives, the position of the camera won't need ...
  • Yes! I was just looking for the lenses for  APSC :-D
