I plan to save for Wacom Bamboo Fun (Medium size) - seems to be reasonable, Intuos are a bit pricey... and I'm not that advanced user. But I already noticed that a tablet would make retouching scanned photos much easier.

According to the AF240Z manual, the "P" mode should set the appropriate aperture on the camera (assuming the camera is in P or Green). This may not work on the dSLRs. It's quite a nice feature (for the bodies that work with it) as it eliminates some of the error.
I guess it is - shame it doesn't work on K20D

The "A" mode on the flash will require you to manually set the aperture on the camera. Use "Av" or "M" mode on the camera (preferably M).

The "M" mode on the flash will, as you say, discharge a set amount of light. However, the advantage with digital is you can easily do a trial-and-error to get it right.
Ah, just hoped there is a secret way to decrease the flash power in flash manual mode. So the only mode which will allow me to decrease the flash power is A (or use some translucent material like bubble wrap on the flash)?

Quote:

In all cases, make sure you FIX the ISO setting on the camera! These older flashes were built before auto-ISO existed (Using the "M" mode on the camera fixes the ISO too)
I used the flash in M mode but I do not set Auto ISO anyway, so probably I'm on safe side unless I chose TAv mode. Good tip, though

Quote:

I'd suggest using fully manual on the camera. Set 1/180s on the body, f/8, ISO400 and work from there. You'll probably find the "A" setting on the flash the best for ad-hoc shots.


(You may also find my flash guide a useful addition.)

HTH!

Thanks for reminding me It's a great source of knowledge. I read it some time ago (when I bought it from you) but then I remembered it was mostly about modern flashes (well, then I thought about buying AF540FGZ). I refreshed my memory today going through it again and enjoyed tips on M and A settings

However, you mentioned there Trailing Curtain Sync mode. Fantastic, I though it is not possible but it works with AF240Z! However it works not as a trailing sync but similar to Slow Sync - it flashes at the beginning, not at the end. Actually, it does the same with Slow Sync. Should it be like that or I do something wrong?

Thanks for the help

Have a look here, which will explain the differences.

On the K20D, Program mode won't work, but Auto mode will, provided you set the camera body to Manual. In my experience, Auto mode works just as well as TTL and P-TTL.
I did before posting my question - but didn't found the information that P mode won't work on K20D - or I assume it just works the same way as A setting looking at the results I achieved (not that I did lots of tests).

Auto will of course take account of any diffusers you may wish to put on the flash.

Experimentation is the key.

Good luck.

Thanks Winter's coming so I hope I'll have some time at home for experiments.

By the way how flash 'knows' about diffusers? I thought that the sensor is below the flash 'window' (how should I name that part?) so it cannot notice any filter on a top of it? Then I wonder how it recalculates the power needed when bouncing the light up?

It just came today off ebay I tried few things and generally I'm quite happy with, but...

I know it's not TTL, so far so good - it wouldn't work on K20D anyway. But it has 3 modes:
P (Program)
A (Auto)
M (Manual)

Now I've read the manual and looked at some archival posts, but still cannot make any difference between A and P apart of aperture setting (4.0 or 5.6). The manual says that in P mode flash should set aperture - but in the fact it doesn't. Both A and P mode seem to work in the same way, they don't touch aperture at all, while set shutter to 1/80s in (camera) Av mode and 1/180s i (camera) M mode (but then I can change it). In these 2 settings flash power is adjusted to the camera settings and flash angle.

In flash M mode it always fires with full power and I have to compensate with camera settings (aperture, ISO and shutter) - I can use the tables at flash's back to calculate the numbers. There is no way to modify the flash power.

Do I misunderstand / miss something?

Finally I've got an avatar - my son put his plastic 'sheriff' hat on my head Can you reproduce the star on the droplet's hat as well then?

Fantastic colours, esp. the 3rd one. #2 is interesting, the water seems to hang over the island or to be a surface seen from beneath.

Looking at #3 and #4 I feel pity for the guy - waiting that long! How often was his counter ticking up, every month? (it started with 365 and went up to 733!)

Nice shots, full of action! 8, 9, 11 frozen in action and sharp, while first few showing the 'speed blur'

When I first read By earlier this year, the firm had cut head office staff from 375 to 125 in less than two years. my thought was they're chopping the managers' heads off...
