Anyone???

Can I assume that my K100Ds P-TTL metering will compensate for the light lost with the Sto-Fen Diffuser.

I think so yes, I believe that's what the P-TTL preflash is for

Have to wait for somebody with experience to post - but my understanding is that it might not compensate in all cases. It should get close - but no garentees

My experience is no, it doesn't compensate. I used the Sigma EF500DG with the DL2 and put on a Sto-Fen. I found in normal use I had to dial in -1.0 on the flash.

The only reason for this, IMHO, is that the Sto-Fen stops some of the light getting out on the pre-flash, so the power is stepped up.

Just my experience.

ihave hadrather good results using my sto-fen and the af-540fgz with the k10d. have not had to change my exposure compensation. comparison shots with and without have definitely sold me on the sto-fen as a decent diffuser but i still want to try the lightsphere as i have heard really great things about it.

I hav the EF500DG with the Stofen and I did note that it slightly overexposed with it atached. Not a big issue.

I have the AF540FGZ but the Stofen is in the post, when it arrives I will try it out and re-post if there are any issues.

I just received mine and have not had the opporunity to give it a good try.



It will be intersting to see how it does and to compare with the comments made here and with your observations.





Thanks to all who answered.

I have the K10D, a 540 and a Sto-fen. I have not experienced any exposure anomalies with that combo when using P-TTL exposure. There is some tweaking necessary if using the flash in manual mode, since there is some light loss (1-1.5 EV) from the diffuser and a bit more from the bounce head angle.

Talking about Stofen....I got one for Christmas...works well for me with a manual flash. The only comment I have is that it is not possible to use this when your flash is mounted on the camera and you wish to take a portrait shot. This is not a problem if you have a flash bracket.

I find Joe Demb's "Flip-It" flash diffuser working very well in both horisontal and vertical positions with a camera mounted flash
