Re: Zenitar 16/2.0 on istD, other istD questions
Hi Shel, I own the 2.8/16mm Fisheye(do you mean this one?). I am quite pleased by the good results (regarding the price of the lens). I used it on my *ist D and the resolution is good enough. I saw no obvious chromatic aberration. Only when pointing towards the sun there was some reflexes visible but not too bad for such a wide lens (one cannot use a lens hood). Best regards, Hans. _ 23a mail
Frames in one burst (was: Zenitar 16/2.0 on istD, other istD questions)
Sylwester Pietrzyk wrote: And the number of frames in one burst is independent from card speed as Dario suggested. Hi Sylwek. You are right and I was wrong (just checked ;-). The number of frames in one burst (5 or 6) truly depends on noise reduction on/off and not on card speed. Thanks for the info. Dario
Zenitar 16/2.0 on istD, other istD questions
Has anyone used this lens on an istD? Does it work as well as a Pentax K-mount? Any pics that you can point to? With a reasonably fast CF card, how many shots can one get off in succession with the istD? How quickly can additional exposures be made when photographing in RAW mode? When using maximum quality JPG? Is there a mode that's equivalent to using a winder or motor drive with a film camera, i.e., can I get two or three frames per second with the mirror going up and down? How many bursts like that is the camera capable of? Does the istD have a shutter speed of 1/4000 second or less? What's the fastest shutter speed? Thanks! Shel Belinkoff

A typical card will write a JPEG file in a couple of seconds, while a RAW file will take 10-15 seconds. These sections answer your questions specifically: Specs: http://www.dpreview.com/reviews/pentaxistd/page2.asp Shot buffer timings: [...] Alex, you are wrng as Dpreview is. *istD has buffer for 6 frames no matter if RAW or JPEG. One thing is nowhere mentioned - you have to turn noise reduction off, as it apparently reserves some buffer space for image processing. After all N.R. is useless during fast continuos shooting so you loose nothing. And the number of frames in one burst is independent from card speed as Dario suggested. -- Best regards Sylwek

I didn't know that about the NR. Thanks for the information. The number of frames in one burst doesn't depend on the card speed, but the recovery time for the next frame does. That is the timing that the dpreview article covers in good detail. alex

Shel, I used it once and was a bit surprised because the contrast seemed low. I didn't investigate or test further because I will probably spring for the DA 14. Joe
