But Tim do you think the Apple computers are worth the price when looking at the hardware?
You can easily compare them now since they use the same hardware as PC do.

If you could easily install Mac on a PC just like Windows or Linux, would you still buy a Apple computer then and do you think Apple could still sell them at those prices as they do now?
Stefan, comments like this just serve to illustrate that you do not understand Macs at all. It is completely NOT about the hardware. Not in the slightest. Apple have changed the Mac processor architecture 3 times now without any difference to their UI. It is ALL about the the user experience.
Of course it's about hardware, you want the processor to do calculations right or are you saying the Mac Pro is just as good as a Mac Mini

They use off of the shelve Intel processors and Nvidia cards with custom firmware but you can flash those.
So how did Mac alter the processor architecture? I've no idea how you can do that with software, might be my limited knowledge.

I bought my Cokin Z-pro kit with holder and 3 GND for €60, that's indeed great value
But I still want some other filters and they are going to be Hi-tech, here take a look link

Yeah Kris is always talking about that and I can see the practical use, of course it must be usable and not to expensive.

The one showed in my link goes from M645 to M42, you probably need a 645 lens to get decent results don't know how expensive they are?

We have the FA and D-FA 100mm macro lenses, and in terms of quality there's nothing to choose between them. The limiting factor is our technique.
Thanks John, that'll do for me!

Will be putting the FA in the market place very soon!

Danny I've no idea what you read in Johns comment though that make you want to trade.

Macro always fetch good money second hand and the prices have gone up, I think I could sell mine without any or little loss.

Is there something like this also for the k-mount? link
I wouldn't mind that I would lose infinite focus as long as I can reach the hyperfocal.

There is something called apparent aperture actually that's the aperture what matters.
However my constant DA*50-135 however the aperture stay fix in the back and its wide open, It all comes down to lens design.

Constant aperture lenses are most often of better design because there is value in having a constant aperture which the advance user can appreciate.
I use the DA*50-135 for portrait a lot at f/2.8 with the camera in manual mode if that would change while I zoom that would mean I have to adjust exposure as well therefore it's also easier to learn how to use manual mode with a constant aperture lens.

Here is some text about filters, read it before buying something. link

Lee are expensive
Hi-Tech is pretty good I believe and for a soft price
Cokin is the more budget one but for the price they are nice

One problem with those square filters is the reflation on the back side so from the camera side, are there any solution for that?

But the diaphragm is opened fully at the wide end.
And you've a turning point in aperture when the lens goes through the register distance. Because wide angle lenses are basicly reversed tele lenses.

But we have lenses like the 17-70mm f/2.8-4.5
