AF360FGZ Problem

Hi, new guy here with a flash problem. I have a new AF360AF for my istDS and am unable to change from M zoom to A zoom and "24mm" continues to flash on the LCD. It happens off the camera or on the camera with any lens. The only things I can change are the mode and flash compensation

I posted this question on another forum and one person was kind enough to respond indicating that I have a defective unit. I would appreciate any feedback or suggestions. Thanks for any help you can offer.

Don't have a 360 in front of me but a couple thoughts came up. First check the batteries. I borrowed a 360 and used rechargeable batts. Some functions would work fine others were just weird. Try flash with some new alkaline batts. I haven't seen a flash act this strange in ages. Was ready to send it in for repair.
There is a switch on the right side of the flash (looking at the back of it) that has white and yellow markings. Can't remember if it has to be in white to allow setting manual/ auto zoom or not. It allows Pentax to use buttons for more than 1 function. Check it.
Also won't auto zoom with lenses that are A or earlier because there isn't anything in the lens to report focal length. Thankfully Pentax allows manual setting for these lenses. I have an older Sigma ttl flash that doesn't. Auto only.
You don't have the little pull out diffuser over the flash lens do you? That overides the auto zoom because it is only used for wideangles. It is easy to miss this. Hope this works.
If all else fails call Pentax and talk to a technician. There are nice helpful people. They may think of something we have missed.

Thanks for the responses.

When powering up, I hear a buzz or hum rather than a beep.

The format swith is set in white in accordance with the manual and the format is 35mm.

The AA batteries were/are fresh and the diffuser was not over the flash. The fact that I can only be in the M zoom even when the flash unit is off the camera and that it makes no difference what kind of lens is attached is making me think that is defective. I will call Pentax tomorrow.

Thanks again for the responses.

If the flash unit makes a buzz noise and the LCD screen is blank during startup your zoom motor in the flash is stuck. It will finally start up but will not go into auto mode. The normal operation for start up in hot shoe is you hear the zoom motor in the flash move and the LCD screen comes on at same time it is fast. It starts in auto mode. I know this sounds weird but you can do what I did and and give it a good swift bump and knock it loose. It works fine on my K10. just make sure before warranty is up right. Got good deal from Amazon $197.94 with $50 gift card $25.00 rebate and free shipping.
One thing, it is hard to mount and remove from body.

See the catchlight in eyes?

XGear: Thanks for the reply. I get about a 5 second buzz before the LCD comes on with M zoom and "24mm" continously flashing. I smacked it around several times as you suggested but it did not change any thing.
I also got the unit from Amazon at the same price. It sounds like you had a similar problem. Amazon is sending a replacement unit but I hope their entire stock of these is not defective. I will post the results of the new unit when I get it.

me too

I bought the 360 at adorama couple of months ago and it was working but the zoom made a huge racket moving one way. it would operate properly as it stepped into greater zoom but when it went into "return to beginning" it sounded like it was grinding gears.

maybe pentax is not detecting motor problems on these flashes

AdamR: Were you able to get it repaired or exchanged or are you just living with it?

Just got the replacement flash from Amazon. I contacted Amazon by phone on Mon., 1/7 and received the replacement today, Thurs., 1/11. I think that's pretty good service. Anyway, it works as it should in A zoom default and results in great exposures. It even works with the 50mm, 1.4 M lens with the camera set on manual. The built in flash on the DS blows the picture away with the M lens.
Much thanks to all who replied.
