Greetings,

this post is a little bit of both, asking your suggestion and sharing with my experience.

Perhaps I must have posted it to the Lightening Technique forum but my questions are specific for Sony Alpha equipment.
I use my new F56AM flash for some time already and am very happy with it.

Most of the shots are bouncing up. I stopped using my 50mm 1.7 Minolta for inhouse shots with low light ever since I bought 56AM.

Experince: I use it mostly with my 18-250mm Sony lens which has ADI. My A200 is set for ADI flash matering.

I use the same angles depending on zooms as suggested by 56AM manual and it works grate. However I noticed that flash keeps zooming together with lens even if bounced up. So I noted for myself that the best light I can get will be with wide pannel extracts, camera gos to 24mm (17mm with wide panel) and I have good light spread equally well.
Changing angle accoridng to distance does it's job well too.
But there are a few questions I'd like to ask:

1. should I switch to TTL matering when bouncing or should I keep it on ADI? As I said my 18-250mm Sony supports ADI matering.

2. when I use my flash wireless, how does the flash understand which amount of light to give? As I understood ADI/TTL will be off for WL.

3. as wireless flash is triggered by built in flash which must be popped up, is there a chance to use two flashes, wireless and another one mounted on my A200? I gave it a try but
a) built in flash poped up: mounted does not fire, only wireless
b) built in flash closed: only mounted fires, wireless does not

4. when mounted, my 56AM flash has slight movement in the shoe. is it normal? :)

Will appreciate your feedback.

Will appreciate opther valuable suggestions upon using of flash both mounted and wireless.
Thanks!
 
hey,

I looked through the link but did not find the answer to my question how to use both: one mounted on body and second as wireless flash at the same time

You dont get to choose that. ADI is disabled with bounce flash or off camera flash. Because the camera doesn't know the actual distance the flash light has to travel.
2. when I use my flash wireless, how does the flash understand which
amount of light to give? As I understood ADI/TTL will be off for WL.
It's TTL. The preflash is a "code" telling the flash gun what to do.
3. as wireless flash is triggered by built in flash which must be
popped up, is there a chance to use two flashes, wireless and another
one mounted on my A200? I gave it a try but
a) built in flash poped up: mounted does not fire, only wireless
b) built in flash closed: only mounted fires, wireless does not
Do you use a A200/300/350 ? If a flash gun is mounted and you manually pop up the built in flash it will display "invalid operation" or something so. You cant use the built in flash with a flash gun on the camera.
4. when mounted, my 56AM flash has slight movement in the shoe. is it normal? :)
Not sure. Minolta 3600 on D7D feels stable from experience.

There is a website dedicated to all those stuff but don't remember it...

I've and old Nissin 3200 GS mounted beside the A700 with a bracket and a pc-sync cable, and I use the Metz 54 MZ4-i in wireless mode, triggered by the on-board flash (covered with a black film).
I use the Metz as a fill-in flash, and the Nissin bounced to the ceiling.
The camera must be set in manual mode.
This is a portrait I made with that combination:

Minor correction. TTL on digital is ALWAYS pre-flash. By definition, it's P-TTL. So with wireless, there is the same pre-flash, of all wireless units, simultaneously.

The exposure is then set, and the on-board flash THEN sends the coded message.

This all happens very quickly, of course.

My flashes felt fine on my 5D and 7D, but they wobble on my A700. Tolerance stackup I guess.

Greg : ok !
& I didn't know flashes were looser on the a700.
Well, they are on MINE. There were complaints on here months ago with an A700 user (or two?) complaining of this. Most of us hadn't seen it, or felt it was normal.

Now, with three cameras, I can definitely say the loose one is a bit annoying, just from a tactile standpoint. But I'm not worried it'll fall off.

I'd bet most A700 owners will not notice a thing.

Maybe that's why I got it on sale. ;-)
