Terry-

Now here is a sample photo from that slave flash outfit at 50 feet.

I am certainly no flash expert, but when I use a flash above ISO800, I start getting some unpredictable results.

It's hard to control flash power at that sensitivity.

I agree with NHL, just get yourself something used andbad*ss with a high GN.
Actually, if you read closely, I was disagreeing with the comment that the slave she's using would be powerful enough to reach out to 70 feet, after I noticed what appears to be a math error in this comment that NHL made (since the GN should increase by 1.4x each time you double the ISO speed, and it looks like he made a math error showing a much larger increase).

I rarely disagree with NHL (he certainly knows a lot more about flash systems than most of us). But, I think he just computed it wrong when in a hurry and I wanted to point it out since he made this comment:

Quote:
Of course both flashes can go further out if you can increase the ISO
Take your Vivitar DF-200 - if you shoot at ISO 400 instead, the GN then becomes 262
-> 262/70 = 3.74, i.e. you can get to 70ft with lens opening of f/3.5 or larger
Instead of the larger units mentioned, especially since budget appeared to be an issue (why spend more than you need to), I suggested something more "in the middle" (in between something like her DF200 and the larger Sunpak 622, yet with enough juice to get out to where she needed at ISO 400 and f/4, with more range if needed by using ISO 800 "in a pinch").

Get the Metz 45 - I just love those dual heads!

Yeah, but the bracket on the Metz is metal...

It fits in a tongue and grove and the Sunpak is plastic with a large metal pin (I have both btw) :-)

Yea, but I'm the one that decided on a smaller and lighter camera, too (5D versus 7D). So, call me a whimp... I like smaller and lighter. :-)

I'm still debating. It's not like I'd need a big flash very often anyway.

Why not a simple flash extender?

101Linda-

Because the "flash extender" costs as much a a good slave flash that can give much more flash range, if I understand the "flash extender" properly.

Judging by the size of this BOWER flash and its strobe tube, I think you are living in cloud cuckoo land. On the shot of the stage , I think its sufficiently lit too take the shot with a telephoto lens without a flash. Just give us the specs of this flash please. Or is your name Mr BOWER.:P
