*ist-D was the only camera to have no flash compensation

The only thing you can do is choose whether it contributes to the main flash or not in wireless mode.

And what a comfortable and strange little world it is here too
LOL!

And what's wrong with DPR anyway???! LOL!

Hi all,
I've emailed the admin team about these continual. Not sure whether anyone is around at the moment I haven't had a reply.

There's been a few more spammers around, and I wonder if the admin team are trying to combat that... but backfiring on the regulars

Hopefully it'll be sorted out soon enough. Please be patient
...and have a great weekend
Matt

Sounds like vignetting...

Need to know:
1. The lens used
2. The focal length used (if a zoom)
3. Whether you were using any filters - and which ones.

A sample image would be helpful too.
Matt

Why does it rule them out?
The whole point of their service is that you upload the image at 100% size - so you can end up with a whopping great JPG for a large print! The cost of a CD and post is negligible, especially when you have a 100% colour controlled system where they guarantee they do nothing to your image - no correction, no scaling, nada, nowt.

Still, if you really, really want to upload, then www.Photobox.co.uk is my choice

RTFL@ George

The 2x polariser trick only works if at least one is a linear polariser. Two circular polarisers will do almost nowt

ND filters & ND grads are easy enough to come by... somewhere like Speedgraphic or SRB Film are good places to start. Or search out a second hand camera place. Cokin A filters are generally very easy to find and cheap.

Pete,
A few points:

* The red indicator is only an indicator. You should rely on the Green "in focus" indicator at the bottom of the view finder

* If you switch the focus switch to "M" (on the left side of the camera at the front) then the camera will let you take the shot even if it's out of focus. The Green indicator can still be used as focus confirmation.

* Under MENU, SETUP, BEEP you can disable the focus confirmation beep (I hate it )

* Under MENU, CUSTOM SETTING:
- Page 3/6 "AF by Press Halfway". I have mine set to "2" = Off. Then I use the AF button on the back.
- Page 3/6 "Superimpose AF Area". You can set this to "2" = Off to stop the red overlay blinking in the viewfinder.

* Finally, it's best to set your focus dial on the back to "centre" so you know exactly where it's checking.

HTH!

ED = Extra low dispersion element(s)
AL = Aspherical element(s)
IF = Internal focussing

There's also a ghostless coating on some lenses (e.g. FA24-90) which doesn't appear to have a designation.
