SF-58 exposure in TTL mode

I noticed when I use the SF-58 on the M8 in TTL mode I always get underexposed files (DNG). The curves in the histogram are all on the left half, maybe a bit over to the right side of the center line, but not evenly distributed.

 

This happens in many different situations where both light and dark subjects are present. I even shot at a blank wall (to ensure even lighting) hoping nothing was there to fool the camera or the flash.

 

I tried setting shutter speed to A or 1/250, ISO to AUTO or 160 (or anything else), and changing aperture to above or below what's shown on the SF-58 screen, but none of these made any difference. Still underexposed.

 

When the files are opened in Capture One the histograms remain the same ( all to the left half) and I had to adjust white point every time.

 

The only way to get good exposure is to set the SF-58 to EV=+1.

 

Does this sound normal? What is your experience?

Have noticed the Leica flash on the M9, so no TTL for me; it sounds like you've found the solution.

The M9's metering is biased towards protecting highlights (at least in my experience); I'm guessing that's why you're getting under exposure in auto mode. I'm sure the more experienced will soon chime in with s better explanation.
