thank you for some great directions here.
Allthough, i'm still undecided ;-)
I really feel for the da300 & tc. It is indeed best compromise on weight, iq, wr,.. and maybe it would just be a good start & see how i go from there.
I don't feel the 150 450 to be too expensive (don't get me wrong though) , but it is indeed another categorie in terms of weight and size. But maybe for what i want to do, i should go with a tripod or monopod anyhow.
I am a bit wary though about spending a lot of cash on a speciality lens such as the 150 450, with pentax. A nikon 200 500 would sell easier eg if one wants to sell it.. the DA300 & TC is not really a speciality lens to me.
I've been thinking about travel also, but i'll take that out of the equation. The da 55 300 will do that.. It is indeed a good telelens, espec for travel. It has served me well already.
All the other options offered are also under consideration. But i have to do some homwork.
The below website has some pics of the place real close to where i live. I've seen great specimens there. But these are really not your backyard birds and they are not tame at all.. That is why i am unsure the da300 & even tc will do.
Also, there is a lot of water. Forget about technique for getting close ;-) well, to some extent..
