the totally covered types are usually for FLs of 50mm and above.. the flower petal types are meant for fast wide angle lenses which are also prone to flare.

Not entirely true, as the DA*50-135 and Tamron 70-200 have a petal hoods, for example. I think petal hoods are generally more effective than round hoods since they are like round hoods but with extra bits to provide even more stray light blocking. One problem is if you don't mount the hood properly and it's not aligned correctly it could introduce vignetting.
Also, petal hoods look more pro and intimidating, especially the big ones on the two lenses I mentioned. Whether that's a good thing or not depends on the situation. For lenses that have a rotating front element, such as the 70-300s, quite obviously they will have to use a round hood.

I stand corrected, my observation would be more applicable to primes. The petal hood for the 50 - 135 is because the portion of the hood at the top and bottom are very long - so if you have a deep round hood with symmetrical widths, there will be vignetting at the 50mm-ish range. Short round hoods would also not be appropriate for the 135mm-ish range of the lens.
And yes! I had a problem once where i did not affix a petal hood on a 24mm lens properly - there was vignetting which I thought was a lens problem. :bsmilie:

Pretty neat, but it makes the FA43 almost double the size.
I read of someone using a DA40mm style hood for all his pancakes, with a matching clip-on cap instead of the real DA40 screw-on one. --> That's what I am thinking of.
I'm using clip-on cap on my DA40mm lens hood.
Are you refering to this kind?

I'm using clip-on cap on my DA40mm lens hood.
Yup, the cap.. that's it.
As for the 'hood', it's this one: http://www.pentaxforums.com/forums/pentax-slr-lens-discussion/73907-my-latest-lens-hood.html
Hmm.... i kinda understand. While the hood would in a way help with the image's overall quality (lighting & sharpness depending on the type of hoods) but improper use of the different types (i believe this would only happen with 3rd party hoods?) would introduce vignetting. Is that right?
I've juz gotten a 2nd hand DA50-200 that comes with a round deep hood but thus far i didn't see any vignetting at the 50mm range. Would a flower type hood work for all?
Sorry for my beginner question. I am a noob in this. Heh..
Thank you.

Insofar that the PF and flare softens the line edges of the object in focus - yes, it does make the image shaper.
Fengwei - any idea where to get one for a 77mm filter diameter, for a 200mm lens?
I got a spare one I think ...

FW, how is the 49mm hood/cap on the FA43 better than original one?
I do think original's kind of cool, but always worried the push-on cap will get lost someday. That's the only downside.

The original cap gets scratched easily, and the original hood isn't deep enough for using on dSLR. After long time use, the cap can become pretty loose too. That's why I use a third party one
you can find out the filter diameter for your lens, then head to your brick and mortar shop or order online or ebay if you can find something you like. mostly aftermarket hood no need so stringent selection lah
does the lens have bayonet slot? if not you'll need screw-in hoods, and be sure to check if the lens front element rotates before buying a screw-in..alternatively you can use a cylindrical hood in stead of petal for rotating front element
hope it helps
