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.

Frames in one burst (was: Zenitar 16/2.0 on istD, other istD questions)

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.

Zenitar 16/2.0 on istD, other istD questions

2004-05-26 Thread Shel Belinkoff
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

 The buffer holds 5 shots.  Once the buffer is full the shot time is
 related to how fast your memory card is.  A typical card will write a
 JPEG file in a couple of seconds, while a RAW file will take 10-15
 seconds.

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.

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.

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.
