With the built-in flash, if you're getting a lot of overexposure with your M lenses, you have to understand that an M lens transmits no aperture information to the camera. The built-in flash goes to a fully manual mode and operates at full power in that case: see the info in the instruction manual around page 150 for how to set the aperture according to ISO speed and distance. (The same issue might be affecting your use of the AF280T, but I've just not used any dedicated external flash with the DS as yet, my external flash is a simple Sunpak 383 auto-sensor model so far.)

Re: flash on *istDs (was: Survey D and DS result)
I can vouch for selling the FA24/2 to get the DA 16-45. On digital, the DA 16-45 is the better lens, being as sharp or sharper in some cases and less CA. The CA is really the biggest problem with the FA24/2 on digital - it was one of my favorite lenses on film. Rob Studdert has done some looking at this too and may want to chime in. As for using the 280T, try setting the ISO to 400 and then doing a few test shots to dial in some minus compensation. I use the AF400T all the time for weddings and end up using about -2 stops compensation. With that, most shots are pretty good in TTL. -- Best regards, Bruce Friday, February 4, 2005, 11:26:51 AM, you wrote: GD> --- Bernd Scheffler <[EMAIL PROTECTED]> wrote: >> I have got a *istDs body three weeks ago and I am quite GD> pleased. >> I am still experiencing what lenses I will like most now GD> because >> some of them are not as crisp wide open as I was used to on GD> the >> fim body.

- Original Message - From: "Bernd Scheffler" Subject: flash on *istDs (was: Survey D and DS result) Another thing with the *istDs is the TTL-flash control. If it's similar to the TTL flash control on the istD, my advice is to forget TTL flash and opt for an auto flash instead. William Robb
Re: flash on *istDs (was: Survey D and DS result)
My SuperA doesn't get any aperture informations from my -M lenses and does TTL pretty well. I should add that my Metz Flash does not support (sca 372) program mode and so won't TTL with any lens on 'A' setting. So I'd find quite weird the IST-DS wouldn't TTL just because of that. BTW I never understood why the body needs to know the aperture for flash anyway (I mean in TTL mode) Thibouille On Fri, 4 Feb 2005 22:05:18 + (GMT), Kostas Kavoussanakis <[EMAIL PROTECTED]> wrote: > On Fri, 4 Feb 2005, Godfrey DiGiorgi wrote: > > > I'm not familiar with the AF280T.

The built in flash on the *istDS does P-TTL and operates with all lenses from the manual focus A-series onwards. With M series and prior lenses, it operates as a simple manual flash, I use it with the camera in Manual exposure mode. I suppose it might work with pre-A series lenses in Av exposure mode, I haven't tested that. It might just think the lens is at full aperture because it doesn't stop down an M series or prior lens in that mode even for ambient light use and it does meter correctly at full aperture.

Re: flash on *istDs (was: Survey D and DS result)
it's more or less the same reason i hardly ever use the FA* 24/2 on my *istD. the CA is too high. i used it a lot on the film camera and the CA wasn't as objectionable. it's a sharp lens, but not as sharp as the DA 16-45/4.

TTL flash does not think in advance, it calculates as the exposure is happening off the film. What you are saying is that there is no off the CCD TTL sensor in the -D/-Ds (sorry I wasn't paying attention when you mentioned the camera you have). Nice! Kostas
RE: flash on *istDs (was: Survey D and DS result)
Some TTL-flashes don't work right with the *ist D/*ist DS, in my experience especially those with a red AF assist light. My AF280T works fine with the *ist D, perhaps with a small tendency towards overexposure (less than ½ stop off). At 200-400ASA most TTL flashes work all right. If youre shooting at 1600ASA, you may get excessive over exposure, though.

RE: flash on *istDs (was: Survey D and DS result)
Girts. I'm guessing: I believe Auto Sensivity should be turned off when using a flash. I'm not shure the camera will be able to shift sensitivity this fast - I mean, when you press the release button half way down to focus, the camera will adjust sensivity to a very low light situation (400-1600). When the flash then fires, the camera must reset the ISO setting VERY quickly to perhaps 200 ISO - and also calculate the falsh duration for that sensivity during exposure. If the camera could do that in a way that would lead to correct exposure, I would actually be very surprised. That's probaly asking too much of the camera, isn't it? I only use Auto Sensivity if I don't know the shooting conditions in advance. When I'm using a flash, I know what the conditions are going to be. I hardly ever use Auto Sensivity, anyway. I choose the ISO setting my self for each sitiation. As a former film user that's still much easier than changing the film/film speed ;-) Jens Bladt mailto:[EMAIL PROTECTED] http://hjem.get2net.dk/bladt -Oprindelig meddelelse- Fra: Girts [mailto:[EMAIL PROTECTED] Sendt: 5. februar 2005 11:57 Til: pentax-discuss@pdml.net Emne: Re: flash on *istDs (was: Survey D and DS result) JB> Some TTL-flashes don't work right with the *ist D/*ist DS, in my experience JB> especially those with a red AF assist light.

RE: flash on *istDs (was: Survey D and DS result)
I resume the hints: - I will fix the sensitivity to ISO200 (or 400). - I'll try to set the flash compensation to the minus side. - I will only use lenses of F-type upwards to avoid problems (and avoid considering them). Seems that even A-lenses are handled different by the camera: On page 147 of the manual you can read: "Using the flash in TV mode / ... Av mode: The shutter speed is fixed at 1/180 sec. when lens other than DA, D FA, FA J, FA or F is used. The built-in flash always discharges fully." I just tried the FA43/1.9 instead of the A30/2.8 with the built-in flash for a close-up of a flower and was quite satisfied. Bernd
RE: flash on *istDs (was: Survey D and DS result)
I did a few experiment shots last week,with 280T and some Saturday with the onboard flash. With the Nikon, it shoots better in full M and settings of 1/60 at F4 or so. I found the D tends to OE a bit in full M mode,but the Av mode,with -0.5ev, seems to be better. I tried the 280T in M mode at F 4-5.6 and shutters of 1/60-1/90 and the laters seem better,but still abit harsh.Not really overexposed but it looks like every light in the world is on,but detail is there. The 280T seems better in a bounce mode with a -0.5 -1.0 in ev. Dave

Book says to use iso 400,so thats what i;m using.:-) Basically so far my tests have shown that Av (using A 50 F1.7)in the 4-5.6 Fstop range with a bit of - ev give ok results.So far i am findingthe istD is less consistant in flash modes than the Nikon D2h,but then i am using an anolog flash on the D and a digital flash on the D2h. So far.LOL Dave Dave
