Re: DA 16-46

2004-03-09 Thread Joseph Tainter
David, the announcement (last August or September) that the DA 16-45 
would be forthcoming was one of the things that made me think seriously 
about the *ist D. Before that I was thinking that I would wait for a 
camera with a 24 x 36 mm. sensor. The DA 16-45 is a fine lens optically 
(in my limited tests, in the same class as the excellent FA 20-35, which 
I also have). The fact that it is a constant f4 indicates that Pentax 
intended it to be a serious lens. Unless you are a primes-only shooter, 
it is an excellent zoom lens to accompany the *ist D. For my use it 
makes the camera very versatile. I don't like the physical design (the 
barrel extends when zooming toward wide angle), but other than that I 
recommend it highly.

I have both of those lenses for my *ist D and think that they both
work well.  35mm has a very similar field of view to 50mm on a 35mm
camera, and 24mm has a very similar field of view to 35mm on a 35mm
camera.

I also have the 16-45/4.  The 35/2 is much much smaller and two stops
faster, so it is often the better lens to have.  The 16-45/4 is much
wider though, and sometimes that is necessary.

On Saturday I was at a friend's birthday party.  The first part of
the party was a wine tasting at a local winery.  The winery is in
the basement of a house, and as you might expect it was very
compact.

At 16mm I could get a wide angle picture like this that somewhat
showed the atmosphere of the party:

(ISO 3200, f5.6, 1/60, 16mm)

I couldn't have taken that shot with a 24mm or 35mm lens.  On the
other hand the composition isn't very good and with a tighter lens I
might not have the back of someone's head in the left side of the
frame.  I was getting a little drunk at the time and mostly taking
pictures at random.

I don't own an MZ-S, but presumably like the Z1-P it can set the aperture 
just as the *ist D can.  Therefore it will "work" fully.  As for the 
vignetting, you may well be right - I have only just got the lens, and 
haven't shot any film with it.

I don't think there is a lot of experience with the DA 16-46 as it is
apparently just now reaching actual users.
I'm curious how well it DOES work on the MZ-S.  Apparently the Nikkor 
12-24 is fine on film cameras from about 16 to 24mm, and it's also
apparently a really good 24mm lens.  The DA 16-46 may also have a useable
focal-length range on film cameras.

You'd be hard pressed to find anything else as wide unless you happen to 
have a 15/3.5 or are willing to go for something like the Sigma 15-30 
(big, relatively expensive) or Tamron 17/3.5, or one of the third party 
14/2.8s.  Personally, I'd recommend against anything with a really big
bulging front element (14s and 15s) as my experience is that they are
very hard to protect from stray light causing flare and ghosting.

There's the Sigma 12-24, which is big, slow, and expensive, and probably 
not yet availible in pentax K mount (?), but will also cover full frame.

If you want wide angle zooms you really don't have many other choices
from Pentax.  The 18-35 exists, but is slower and also won't work with
your MZ-S (no aperture ring).
Since you can apply for the rebate I think that getting the lens is
a no brainer.  If you don't like it you can probably apply for the
rebate and sell the lens slightly used for more than you paid.

Hi David,

when I was at the very point of your decision,
I got myself the new Tamron XR[DI] 28-75 f/2,8  - which is a fine lens.
I realised that for me constant f/2.8 on a zoom was more important than
to have hefty wide-angle on a "walk-around lens". Because that's what a
zoom is for me mainly, for "serious" work I still use my fixed focals.
To have aperture ring and full image cirle is also fine, because I still
use film!

If the DA lenses where sooo much better by wide a margin, I'd consider
buying a digital-only lens, but from the samples I had seen, it was a
no-brainer to go for the Tamron - regarding picture qualtiy. The rest,
as you say, boils down to personal preference ;-)

All the best,

Thomas
