FZ20 exposure lock
I'm looking to buy an FZ20 soon, and since I shoot a lot of panoramas, I was wondering if it's possible to lock exposure while in shutter-priority or aperture-priority modes? I can always go into manual mode, but from what I've read about the EVF/LCD low-light problems, I hope to avoid the manual mode in low-light situations.
The FZ20 manual didn't say anything about exposure lock, so I'm guessing it's not available. Please confirm.
Thanks so much! (Apologies if this has been asked before. A search of the forum didn't find anything.)
