these look better, the corp was to intense. Was trying to figure out why the look so off.

The delta shot show either motion blur. Or it might a bit oof.

I was trying to aim with some advance for the slow focusing, seems unnecessary. This lens focuses much faster than the kit lens. I did not miss a single shot (I got a lot more shots), impossible to do a second shot though.

I'll do some video next time. I did try (in C-AF mode), but not able to see anything in the sky. When I finally realized that C-AF did not work for such situation, my time ran out and had to leave.

c-af work with the panny, but it blacks out during the refresh, so you can not track the target. Try c-af-tr. It may give you better results with the lcd.

I could see each plane for only few seconds, no time to do C-AF-TR or C-AF. It was either a hit or miss for each big bird passing by. I used S-AF and I should have used this mode for video too.

The shots I took were at take off, with c-af-tr. I was able to get about 3 shots in focus, but my dslr was more like 8 shots before the plane was gone.

The zoom ring is very stiff. When I turn it, the lens base rubbers back and forth against the camera, not a food thing.

Being a metal mount, a little play should not hurt. Having used zooms in the past that could zoom in and out on their own if I pointed the camera up or down, a little stiffness in the zoom ring in my opinion is not a bad thing. It'll stay where you put it.

My DSLR version of the 40-150 has some issues towards the long end due to what I believe is a decentering problem that only becomes obvious at the higher magnifications. You'd hope this micro version, at almost three times the cost, is a little better in terms of construction tollerances.

I think this lens is all plastic including the mount. Every part is extremely light, the zoom tube won't go out easily by itself like a heavy metal one. The price should soon drop to $200 or even lower, it does not worth $300.

BTW, the zoom tube extends out way too much, as can seen in the youtube. The Panny 45-200 is 200mm vs. 150 and it goes out much shorter. This lens is too long at full length, scaring people.

The DSLR version also extends out like that, as does the 14-150 micro lens, the 70-300 DSLR lens....pretty much every Olympus Digital Zuiko zoom lens that extends out to 150mm or longer.

From what I can see here...

http://www.photozone.de/olympus--fou...pana_45200_456

...the 45-200 Panasonic extends plenty on its' own as well, looks plenty long, especially with the hood fitted and is a physically bigger/heavier lens (all are lighter than my Olympus 50-200 SWD though!) than the 40-150 due in large part to the built-in OIS. You should snap an image of the two next to each other zoomed to their maximum settings, without a hood fitted, so we can see the difference between the 40-150 and Panny 45-200. I have never held the 45-200 Panasonic.

the alternative is to build a physically longer lens and make the zoom internal. The 70-200 f4L Canon zoom has an internal zoom mechanism so is the same physical length whether set to 70mm or 200mm, but it's also built into a housing that's longer than it would have been had the lens been built as an externally zooming lens.
