Absolutely splendid, why don't you upload it in the fortnightly competition, or don't you do that so to give us a chance

Lovely shot, he or she is really enjoying it

I don't know how the Pentax K20D works but Matt said you can shoot all shots with only pressing the button once so if you set it on 2 seconds delay and it will take all 5 or 3 shots, a remote is hardly needed.
Although remotes around that expensive so you still might want one, they will come in handy with some shots.

Paul,
Amin is posting a lot of shots from the DA* 300mm with a pentax TC 1.7X converter in the my photo section here, maybe that's something for you?
The TC will drop the F4 to something like F5.6 or a bit more I believe but that lens is quite sharp wide open and with the 1.7 TC it gets a length of 510mm. It's also a lot more handable then those large zoom lenses.

A monopod will also do the trick and you will be a bit more mobile if you need it, although it isn't as stable as a tripod.

edit: Scottie beats me too it with the monopod

That swan is lovely Amin!
try black and white on it, the water might give a nice effect against the swan.

here is some noise reduction with Topaz denoise, I also have Neat image but since I've the photoshop 64bit version it doesn't work in adobe itself but if you want i can also upload on with those for you to compare it with.

I've also finished your shot of the... how is that bird called? we call it a roodborstje (redbreast)
This how I would have done it

You have my tools, i simply did the one with the softlight.
Then 3 adjustment layers (curve, levels and vibrance) adjustment layer looks like that jin-jan sign and you find it under the layers in the rigth corner.
Cruves is set on Linear Contrast.
Levels on the values left to right 0 - 1.83 - 190
Vibrance the values +59 and +23, this will bring the colour back.
It looks a lot like your image so I don't think you have done much differend. This is how i usally work now, it does the job for me and fast.
I hope you like it Amin

edit:
The typing of the comment did so long that you've uploaded some more, those are all geat Amin. the DA* 300mm is certainly on my list

Overexpose the shot a bit and make them darker afterwards on the computer, that works most of the time. Also don't be afraid to aply some noise reduction, the camera hardly aplies any with the thought that you can do it a lot better on the computer. There are some great third party software out there that do a great job. Neat Image and Topaz are the ones that come to mind.

WOW stunning shots Amin, I want one too now

The first shot of the king fisher is simply splendid.
Just use the clone or the spot healing brush to get the white line away and maybe just make it a tad brighter so that the colours come out more.

I will have a quick go at your first photo but I've 600 shots still waiting to be processed myself

Could you please also post some shots with the macro?

Both are also very differend cameras, your shooting style would be very different with the LX3 then with the K200D. They arent the same thing and can't be really compared in that matter.

The sensor of the LX3 is smaller so you have more noise when shooting at high iso, with the K200D you can get it higher with less noise which resulting in shorter exposure time and so in a sharper photo

The CA is quite easy to remove in todays software, not really something to worry about if you post process your photos any way.

But he also wanted a faster lens.
Maybe a FA* 600mm F4, you can special order them with pentax if you want one

There's also a FA* 250-600mm F5.6 but that one isn't in production anymore.

The 600mm will cost you around $5,600.00 and the 250-600mm $7,400.00.

The Tamron 200-400mm is a fine lens for wildlife, simply mose the iso up too 400 and stopdown the lens a bit and it will do more then fine.
Most members use something like your Sigma 70-300 for wildlife.

Luckly it isn't memory, they measure activity in the cerebral visual cortex. they now know enough on how that part of the brain works so they can read the patern and translate it to a image.

Amin, I would also very much miss the sound and the feeling.
Have you ever hold a n old SLR camera, which you need to trigger.
just lovely the sound and the feeling they make.
