George, I said it was BETTER than pretty poor. "Pretty poor" were Jealousy's words.

Incidentally, I've posted a question on Pentax-A 28mm versus the 18-55 on the Lenses section, and would be interested in any replies there. Thanks.
I apologise. My brain seems to have ignored the "better than".

that lens will certainly be no better than the DA 18-55, and probably quite a lot worse....
Thanks!
I have the kit 18-55 lens. Just thought this was a bit wider.
When I studied optics, 18 was wider than 19.

How likely is it to be better than the Pentax 18-55? The 18-55 is better than "pretty poor" according to www.photozone.de/8Reviews/lenses/pentax_1855_3556/index.htm

What part of the range is most important to you? What about a used Pentax prime lens?
This is what they actually said:
The Pentax SMC DA 18-55mm f/3.5-5.6 AL is a surprisingly good kit zoom although it has its weaknesses specifically at 18mm. The center and border performance is fine here but the extreme corners are somewhat soft. Pronounced vignetting and reduced contrast are also present at f/3.5. At 35mm and 55mm the situation is much better. CAs are very well controlled. The build quality is good for a kit zoom and a level up from the rest of the gang such as the Canon EF 18-55mm f/3.5-5.6 or Nikkor AF-S 18-55mm f/3.5-5.6 ED. All-in-all a good offer from a price/value perspective but naturally there're better lenses out there ... with a much higher price tag.

Where did you see "pretty poor"?

are you saying that silkypix has better NR than neatimage? or just that its still a big improvement on none?
I have bought both. NeatImage has its uses. But I find that Silkypix does the job at ISO1600 perfectly (that's the full version, not the free) - once you know how to work the noise reduction
(George - I know what you're going to say It's on my "todo" list which is rather long )
Matt
Matt, I know you have a long to-do list. This is the fate of all helpful people of above-average competence.

So with that in mind, I ask nothing more than that you place this project at the top of the list.

What could be more reasonable than that?

The *ist-D was excellent, and I pushed it to its limit and have consistently got quality results from it (several have asked if the prints were from medium format). The K10D is much better, a complete joy to use (fast, intuitive etc) and is only lacking one or two very minor things - it's nearly my perfect camera

To be honest - as you haven't actually got a K10D, you don't know what you're missing

Matt
Matt, could you please stop that. I still have the *istD and are quite happy with it. It's posts like yours that make me want a K10D because they are giving me a taste of what I am missing.
I really would like to stay with the *istD for another while.

On the topic: It would be complete waste if the 22-bit conversion would be instantly and linearly converted back to 12 bit (wouldn't that just mean chopping of the 10 LSB's?). I don't think the Pentax engineers are stupid and I sincerely hope that the marketing department didn't talk them into doing such stupid things. Therefore I assume that it's not as straight forward as that.

Prieni
Prieni,

Here's some comfort.

My K10D has a problem at the moment, so I have dusted off the *ist D.

It's a pleasure to use, and reminds me of when I had both a Z1-P and a Super A. Although the former was the better camera in terms of spec., I preferred to use the latter. It was just smaller and nicer and simpler. And of course it did the job. Same with the *ist D.

In my view the only thing wrong with the *ist D is that it's slow to process the images, and in consequence fills the buffer rather quickly.

If that's not a problem with your style of shooting, then the *ist D is still a wonderful camera, and frankly the inage quality is not massively worse than the K10D. Using a good lens affects the final image more than the inate difference between the cameras (IMHO).

good points, i will keep thinking about it, although i don't know if i'll afford a K10 before the next new thing comes out...

i guess i'm frustrated with trying to nail the exposure so the resolution is where i want it, its much more than just filling the histogram (and in low light even that is hard enough).

i have a real world example of that, but it will be a day or 2 before i can dig it out and post.
Bracketing might help.

Hi George,

What I thought I was measuring was the trigger voltage as per the article and instructions here -

http://www.botzilla.com/photo/G1strobe.html

I know the main article refers to Canon but it seemed relevant to any other camera/flash.

If I was not doing so then it's down to my ignorance. However I was very interested to read your comments

Although I'm not sure if I'll put the latter theory to the test.

Thanks also AlfaFoxtrot for your response, as I said above I was only following instructions.

Howard
You can only measure the actual trigger voltage at the instant of triggering, and for one reason or another it might differ somewhat from the voltage across the terminals when they have not been shorted.

But it's irrelevant. If there is just a small voltage across the terminals when you do the measuring, then you can (I believe) safely assume that you will not suddenly find 500 volts going through when you press the shutter.

I don't know if home multimeters will be good enough to measure voltages across the flash, they build up to a high level then discharge almost instantly, so the meter probably won't be able to recognise it, or will at least not give an accurate reading.
What you are testing (as I understand it) is whether the flash discharges through the hot-shoe circuit, or whether shorting the hot-shoe circuit triggers the discharge through a different circuit.

If the former, the measured voltage will be hundreds of volts (as it is with my (very) old Bowens studio flash unit, and some early Vivitars).

If the latter, the voltage almost certainly will be in single figures, or just over.

You are NOT trying to measure the actual discharge.

It is my belief that this whole question is really a non-issue. For many years, flashguns have used a separate circuit to trigger the flash. I doubt if a single flash unit made in the last fifteen years has discharged through the trigger circuit.

And even if you are unlucky enough to find such a flashgun, Pentax cameras have traditionally been able to handle it. I haven't tried the K10D with the Bowens yet, but all my other Pentax cameras (including the *ist D) have handled the Bowens without a problem.

This is all blown out of proportion by people like Wein, who make a lot of money out of selling expensive and unnecessary junk to frightened photographers. You are much more likely to be killed in a car crash than you are to damage your camera with a flashgun.

The ability of the camera to fire the remote flash using the pop-up flash is a recent improvement (dependent on your upgrading the firmware), and unless Pentax have updated the manual, you will not find it mentioned.

He looks rather well-endowed around the chest for a male marathon runner. And I wonder if those safety pins hurt.
