This is the reason that ND filters are available and necessary.

1/4000sec max shutter speed not enough

They probably never faced a situation I described. Besides I must be one rare, bokeh-obsessed person.
I thought I mentioned bokeh in my original post. I was not after wide DOF coverage in that situation. I wanted the opposite.
BTW, it was YOU who mentioned that 1/500s max in your other post...not Hansplast26.

Yeah, I believe that's doable because I even saw an ND filter specs (at B&H site) which provide exposure reduction of 20 stops.
I now retract my statement on my original post. My apology to Canon. ;-)

True, but they are interline not full frame sensors so the fast shutter comes at the cost of a loss in sensitivity.

Man , you need to learn the basics first ; get Understanding Exposure , the new one , ( author is Brian Peterson ) , and you won't be sorry.
You need to understand your basics first man...
I have a 25 years old slr ( Praktika , made in the former Democratic republic of Germany ) with a maximum shutter speed of 1/250 secs , and I can shoot with it all day long at the beach in Australia full sunlight with a 50 mm lens...And the light here is very harsh ... Photos are just beatifull.
cheers

That's even more limiting, huh?)

I'm very sure I know the basics of exposure. If you'll read the exchanges of messages above first, you would know what the issue really is. Needless to say, I already found the solution thru the help of the knowledgeable photographers here (thank you-all).

this thread http://forums.dpreview.com/forums/read.asp?forum=1031&message=13426563 talks about using EC and RAW conversion to go from ISO1600 to ISO3200 or 6400 so would the inverse work? going from ISO100 to ISO50 or 25?
i don't know if it actually works that way or not but it might be worth trying? does someone know if it actually works that way or not?
ie would setting the EC to +1, taking the image, then in RAW conversion setting it -1, would that effectively drop the ISO to 50?

Your question of "That's even more limiting, huh?" seemed to indicate otherwise.

Technically, yes that would work. The problem is, whenever you push or pull, you are sacrificing one end of the scale.
When you push from 1600 to 3200, you lose some of the shadow. However, that's not a problem because most people won't notice the difference between pure black and almost black.
When you pull from 100 to 50, you lose some of the highlights. This is where the problem is...out eyes are more sensitive to the highlights, and we can much more easily see the blown highlights. Most people will see the difference between a solid white sky and a white sky with very subtle shading and texture to it.

If people wanted the kind of DOF that f22-f32 would bring about why would they pay $1000s for lenses that open up to f1.2-f2.8? Fast lenses are not just about getting faster shutter speeds, they are about controlling DOF. Isolating your subject through shallow DOF is a typical requirement and requires high shutter speeds and/or ND filters in strong lighting.

Don't you know that ISO200 @ 1/4000s overexposes worse than ISO100 @ 1/4000s? I think you need learning more than I do.

I can't get a shutter faster than 1/200 with a flash.
When I try to use the flash outside to get the shadows of the faces,
the shutter drops to 1/200 and everything
gets overexposed.
How can I get faster shutter speed when using a flash?

The only way to get faster flash sych appears to be to install one of the available hacks.

It is not that my right hand doesn't know what the left hand is doing - it's just not very interested

You get high speed flash upto 1/2000s. I do not know if e.g. 420EX has this same feature.

You must have gotten mixed up in this conversation, because I never said anything about me not knowing. I know very well. You were the one who, when told that:
"u think u have a problem..wait till the D50 hits the market with minimum ISO200 and max shutter 1/4000"
you responded with the question:
"That's even more limiting, huh?"
indicating that you weren't certain how it worked. Maybe it was just a tongue-in-cheek comment and we misinterpretted, but it didn't seem that way to me.
But you said it, I didn't. Don't go around putting words in my mouth

ISO 200 and 1/4000 is more limiting than ISO 100 and 1/4000.

The 420EX has this feature also.

This thread is, unfortunately, getting a little over-heated and, without in any way trying to be unhelpful or maliscious, I would sincerely suggest to the gentleman who started the thread that he stop blaming his equipment and take time out to get a good book on basic photography - perhaps by John Hedgecoe - and so gain some proper understanding of exposure and ND filters etc.

I KNOW THAT. I NEVER SAID I DIDN'T. PLEASE POINT ME TO WHERE I SAID OR SHOWED THAT I DIDN'T UNDERSTAND THAT.
Sorry for the yelling. You are now the second person to essentially put words in my mouth. It was the other person who responded with the question: "That's even more limiting, huh?". When you ask a question, it usually means you don't know, so that's why we figured the OP didn't know. Like I said, maybe he wasn't asking...maybe it was a tounge-in-cheek comment, but thats not how I interpretted it.
