OK...I am going to ask a very, very basic question. I'm not 100% sure how to use the red and green lines on the back of the AF280T flash. Do we set the proper ISO on the slide, and then only use the values between the W and T indications on the red or green band, depending on which Auto setting you use? The lines extend beyond the W side in each case. How do we interpret that? Is that still supposed to be a usable range?

Thanks
The red and green lines correspond to your selection of high/low power, and tell you the effective range of your flash at that setting in auto mode. The lines extend so that any ISO value will have a reading, within reason. So set your ISO, then select the aperture that gives you the range you want. I am working from memory here, but that is the basic idea. I sold off my AF 280T a long time ago.

Yes, it indicates the covered range of each mode.

Thanks, i see that it prescribes using f8 for the green setting or f4 if using the red, but I don't understand what roles the W and T indications play.

They are for using wide or tele adapters.

Wow....it's like a lightbulb just went on! I didn't understand that those are guides for when an adaptor is used. Thanks!!

K-x + AF280T

I was chatting with members of my photography club about flashes, specifically my older Viv. 285 which I cannot use on any Pentax digital, so I decided to haul out the AF280T I bought a few years back but couldn't get working properly with the K10 or K-x. Todays tests showed that with the camera in P mode and the flash in either green or red, iso at 200 with an f4 18mm wide lens mounted I let the camera set it's speeds and I took about 10 shots without any problems. I used green for close in shots of my cat and the red for shots or a couple of meters. tried it in the kitchen with lots of ambient light and shiny stainless surfaces and then went into the dark (no lights at all) living room and again I had good results with proper exposure. I have all florescent lighting in our home and ambient light photos just do not have proper color the K-x is better than the K10 but never quite 'right'. The AF280T fixed that problem too with colors becoming correct. Even when I tried in the past to use on camera flash the results were not this good. I do not do a lot of indoor shots but I now know that I can use the 280 and get good results.
