Go long. Hand held.
I read in a couple places on the web that the Panasonic fz 1000 was a little soft at the long end and this concerned me because the long reach of the Leica designed lens was one of the reasons I bought the camera. It's also one of the features I used extensively on my recent, downtown Austin project.
But I did something a bit out of the ordinary for web camera reviewers --- I actually went outside on a nice, sunny day and shot some tests. I shot the tests with the camera locked down on a stout tripod and also handheld. Guess what? The long end of the lens is sharp. The secret is to use it intelligently.
A primer for testers: To find out just how sharp any lens can be turn off the I.S. put the camera on a tripod and use a self timer for release. Make sure you focus correctly instead of depending on some automatic focusing point selection algorithm from the camera. Maybe use that boring, old, center, single point, AF method! Now you have an understanding of the potential of the lens and if you want to you can take it off the tripod, turn on the I.S. and shoot tests that might show you how sharp the system can be. But please, tell your readers if you shot the 400mm sample while riding on a street car over bumpy track at twilight, holding the camera at arm's length with one hand, to view the idiot screen, on the back, while your other hand grips the safety rail of your conveyance.
But really, the point I'd like to emphasize here is how important it is for one's credibility to actual go out and do the test instead of taking one of the other web shill's word for something, and then passing on flawed information.
Wow. That sounded like a rant. Okay, well I just get tired of reading misinformed crap.
