I took some more test shots with the 42 last night. If the 58 communicates white balance to the camera as well as this little gem does, Sony will be solidly building on the outstanding Minolta flash system IMHO.
I have patiently awaited this new 58, planning on buying one for quite some time. However, the price announcement and the additional 3 month wait put me off. While I would love the added features, I don't see myself needing them at this point in time. Perhaps in the future...

I know this is a thread about the new 58 flash, but I have to tell you again...this 42 produces better pics than my 5400HS did (a lot better!) and I really liked the 5400HS. The colors are spot on, and when using the "D" lens and the ADI function on the camera, I am amazed at how perfect the exposure is, especially on tricky reflective subjects.
