Tom,
You're correct I used an external flash with my, now long gone, 35mm film SLR and it worked great. My current take is a camera that is "easy to carry" and convenient. My current Panasonic FZ-30 could use an external flash but in 3 years I never needed one so I guess I just didn't get one. The built in flash worked fine for me and the indoor flash pictures that I took looked GREAT.
As you all know I neither want to carry extra lenses nor an external flash so the external flash is not important to me.
The item I have struggled with the most is the electrically controlled zoom but after 2-3 FZ35 trials I find it's okay because when I push the lever full left or right it telescopes FAST but if I push it part way left or right it moves very slowly so I can easily frame a telephoto picture to full the entire frame.
I still find that the Panasonic FZ35 is my favorite "almost" DSLR camera. I even downloaded the detailed 200+ page manual, printed it, and read it. It seems to have more features than the competing Canon, Nikon, and Olympus competitors but, that's not so big deal because from 3 years of experience with my Panasonic FZ-30 and all it's features I do not use but about 1/3 of all those many features.
Another thought on how lightly I like to go when I carry the camera on a hike, rally, to someones house, or anywhere is, I don't even take my camera case. I just stick a second battery in my pocket and take my FZ-30 SANS any lenses or external flash attachments.
So now the world knows my bias' re cameras.
In fact, today (12/30) on our trip to Sabino Canyon here at Tucson I only used 2 camera settings, the P (Automatic) and the A (Aperture) settings and no tripod. 99% of the time I only use the P, A, or S (Speed) settings. Yea, I know I'll never match Marabito, Buchanan, or Silerbird's quality but I can take my photos faster (less overall time) then they can if that counts! BTW, that doesn't really count it's just a joke.
Good luck on your quest for a camera,
JerryF
