Anyone have one of these?

I have an existing Pentax film SLR with a lens marked:

SMC Pentax-FA
1:3.5-5.6 28-80mm

Since the Pentax *ist DS2 comes without a lens, I hope to use my
existing lens with it and save some money.

BTW, B&H sells them for $750:

Is that a question? :-)

Yes, you can use your FA lens with the *istDS2. If you get the DA lens
that comes with the DS, you likely won't be able to use it with the film
camera, unless you like a lot of vignetting.

Brian,

Spend the extra and get the kit 18-55mm lens, it is a pretty good little
lens and is nice and wide for landscape and indoor use. If you get one in
with a kit it will not cost much. I have a Ds and use the 18-55mm lens a
lot, I have a faster 28-105 but find the smaller lens more versitile.

Cheers.

If I had it to do over again, I wouldn't get the 18-55, and get the
16-45 instead. Maybe I got a bad one, but the 18-55 is kinda soft and
has vignetting at wider zoom. I leave it on the camera so there's
something relatively unobtrusive that I can pick up and shoot with, but
it's not that great.

BTW, Pentax has their current lens offerings listed here:

I've got the DS.  And I sold the 18-55 right away.
It's not a bad lens by any means, but it is *slow*.
Many reasonably-fast AF lenses exist and at a reasonable price.
Just adding an extra $50 can get you a nicer lens.
And the lens is what it's all about.

Both shot with FA50/1.4, 1/60 @ f5.6.
The violin needs some work (compositionally, that is)
but the dried roses came out very nicely.
The DS does a good jpb.
The DS2 is the same body with a larger viewing screen on the back.

Pentax ist dl

Thanks Don

Can you point to examples of these lenses, the 16-45 ED is considerably more
than the basic 18-55mm and had better give better results.

Jeez, I hate those multi-colored backgrounds. With the violin, you've got
100% improvement with a solid color, black, white, red, almost at the
"whatever" stage. Think about all white, or black, really bring the whole
emphasis in on the violin and bow.

Or not, too. Just a suggestion.
Cheesehead - 16 Dec 2005 21:10 GMT
Thanks.
It would have been better with more powerful lights
so that I could have stopped down further and made
the background go darker.
Or if I'd directed the lights a little differently.
Anything to get the background to go darker.

It's pretty new and not widely available yet, but the DS it replaces is
virtually identical (especially after doing the firmware upgrade), so a
few of us here can comment.

Note sure if you are thinking it *only* comes that way.  You certainly
*can* get it with no lens, but most retailers sell it by default in a
kit with an 18-55 zoom.  After applying the 1.5 magnification factor
(due to the DSLR sensor being smaller than 35mm), this would give
basically the same results as your existing 28-80.  Your 28-80 will
work, but you won't really be getting as wide as 28 - it will actually
be more like 42, in terms of what you're used to.  On the plus side,
you'll be getting a lot longer than the 80 you're used to.  If you can
live without the wide angle, go for it.  Otherwise, youre probably
better off getting the kit.  There are, of course, other lenses
available as well - such as the 16-45 already mentioned - but they are
rather more expensive.  If cost is a major concern, I'd be thinking kit
unless you are *sure* you won't want the wide angle.

Thanks.  Will the 1.5x magnification factor be evident when I look
through the viewfinder?  I don't have a good feel for what the zoom
numbers mean.

Well, on my  *istD with 16-45mm lens, it means that the 16mm is equal to a
35mm film camera (or full frame digital)with 24mm at the wide end. Multiply
it all by 1.5, in other words. It is evident in the viewfinder in that you
get that view. There's nothing flashing to say, "Hey, bub, this is the
equivalent of 24mm, not 16mm."
Marc Sabatella - 13 Dec 2005 04:09 GMT

Yes.  As with any SLR-type camera (digital or otherwise), what you see
in the viewfinder is pretty much what you get.

>  I don't have a good feel for what the zoom

They refer to the "focal length", the exact meaning of which isn't
relevant.  What *is* relevant is that smaller numbers mean a wider angle
view, larger numbers mean a more "telephoto" view.  You might want to
spend some time with your film camera looking through the viewfinder,
zooming in and out, and then checking the lens to see what focal lengths
you like (the numbers are printed right on the side - just look for the
numbers change when you zoom in or out.  If you find yourself never
using the focal lengths below 42, then you'll be perfectly happy using
the lens on a digital - zooming all the way out to 28 on the digital
will produce results similar to 42 on film.  If you find you are often
zooming out and using focal lengths in the 28-42 range with film,
however, you'll be disappointed when you mount the lens on a a digital
and find that a focal length of 28, which on your film camera might
allow you to get most of a room in a shot, ends up cropping out way too
much on the sides (the equivalent to what a setitng of 40 would do on
your film camera).

With film, 28 is considered fairly "wide", 40-50 is considered "normal"
(similar to what the naked eye perceives), and bigger numbers
"telephoto".  The 70 at the long end of your lens isn't very telephoto
at all with film; "real" telephoto lenses would be in the range of 100
to 300 or higher.  So at least the 70 on your lens will be equivalent to
a 105 on film, which is noticeably more telephoto than you've got now.
