Photokina is coming as you can see Canon, Nikon and Sony have announced new cameras and there are some rumours about Pentax, with some luck those rumours are true and you might see more second hands appear on the net.

Very interesting, won't you loose a lot off performance that way?
Might you have a good site for me so I can read more about it?

Thanks Stefan, I'll read through that tomorrow, but that's not as high as the resolution I'm talking about. Zeiss have managed 400lpmm on film (which is really tiny 0.0025mm). This site gives the maximum digital resolution as 87.5lpmm which means the testing setup doesn't need to be anything more than a decent tripod. Normal film testing used to yield 120-140lpmm again with just a decent tripod.
Didn't knew that about Zeiss, very intersting.Thanks Stefan, I'll read through that tomorrow, but that's not as high as the resolution I'm talking about.

About the maximum for digital if you read further you see it's the resolving power of the 40D and not the smallest that's possible for digital.
Also when you read even further he is saying you can't actually calculate it that way because more is going on so it's even less.
This a very detailed article about maximum sharpness of the lens and when a sensor out resolve it. link

And why we shouldn't/can't compare film and digital link
More then enough to keep you busy for the day

If the a100 and a200 fill you need what about the Pentax KM?
It has the same sensor as the K10D and the K200D and it's still considered as one as the best low ISO sensor from Pentax by some users here.
The only thing it doesn't have is weather sealing, no top LCD and it's missing focus point notification in the viewfinder but for the rest there is nothing negative to say about it compared to the rest.

Could you explain that a bit further?There is far too much of this complete nonsense going on and despite recent rulings in the European Courts - we photographers are persecuted daily.
I live in the Netherlands and have yet to hear off such cases as in England so how can it be the European Court?

Digital has poor resolution anyway
Don't say that so easy, it's hard to truly compare the two formats since they are different.Digital has poor resolution anyway
Here is a comparison 7 years old with a 135 format DSLR against a Pentax 6X7, according to you the DSLR doesn't stand a chance, here just take a look link

You mean where Tim said 24 f2, didn't connected that to the FA*24 I'm guessing the fact that Tim already mentioned it.

And to a lesser degree the OP wanted something around f1.4.
Indeed but the OP mentioned two f/1,8 lenses and that is 2/3th slower than f/1,4 so thought he wouldn't mind to go a full stop slower. Also the suggestion of the FA*24 was as an alternative for those, not much to do with the first comment.And to a lesser degree the OP wanted something around f1.4.

And to an even lesser degree the OP did say "new" lens, although this could have meant new to him.
I did commented that you probably will not find it as new so I did thought about it.And to an even lesser degree the OP did say "new" lens, although this could have meant new to him.
I've explained myself so lets get back to the thread.
@Tim if you want new lenses that fast and wide than the Sigma you mentioned are the only option.
Pentax make nothing like that any more although they did mention a DA*30 lens but that was 2 or 3 years ago and we are still waiting, also Tamron has no lenses either.
If you don't mind going manual focus and f/2 than some other options might be open.
Voigtländer Ultron 40mm f/2
Carl Zeiss Distagon T* 28 f/2
Carl Zeiss Distagon T* 35 f/2
They are all hard to come by but not impossible here at least, some shops should be able to order them for you.
Edit: several spelling mistakes

It normally isn't a problem, the drainage couldn't handle the amount of rain.
