solid construction. Its cons are: wide open is only f/2.8, and it doesn't seem

Hi!
Setting aside the distinctions between DA, D-FA, FA, F, A, M, and basic
K lenses, I wanted to discuss focal lengths for the *ist-DS.

Hi!
A few things you might consider to sway you to the DS
* The 4-way rocker on the DS is a bit better.
* Slightly bigger LCD
* Slightly faster frame rate and bigger buffer

* SD cards may be more robust (though I have no evidence to

I see the DA 40 as an alternative to the 35. The 50 is much faster.
The real advantage of the 40 is that it is so small (and has that

a big coat pocket. It's just flatter than many other SLR/lens

Before taking apart my ist DS, I am wondering if this digital body
containts a mechanical shutter, or is it just firing up some electronics
during the exposure time.
Thanx.
Johan.
(Great camera, especially with an 50mm 1.7 A :-) )

It's mechanical.
If you do take it apart, be sure to post some photos of the innards to
the list

It has a normal focal plane shutter

But when I do, I'll send them. (Ofcource, the photo's are then taken
with a low budget digicam)
Do you mind if I ask why you are taking your Ds apart?
Cheers,

They are required with the dslr type
This guy took the top cover off his DS to replace an eyepiece element
and provided a couple of pictures of the camera dismantled to this

apart by me. It can take one
year, it can take much longer (in case of the ist ds I hope it will take
very long.) Most of the time because it's broken.
So, I hope it will take a long time before it happends, and at that time
Pentax has hopefully released another generation of digital bodies, so
Sounds like the same disease I have.
Curiousititis. ;-)

That's some wirey mess ;-) (seriously - not at all, you should see the
old Fujicas...)
That could be an incentive for list members to replace the plastic
eyepiece lens with a glass one, just like some did with PZ1p!
Good light!
