I've no experience with it but I believe no one has the lens here, I've thought about buying one though so I did some research.
The build quality is obviously good but the Bokeh is not super in my eyes it's quite distracting the sharpness is good it's a bit sharper wide open but around f/4 they are the same.

If you want to use the lens wide open then the Zeiss lens is better but at around f/2 and up I would go for the DA*55 which is there for the same money but has a slightly better bokeh and AF and weather sealing.

Where do you want to use the lens for if I may ask, do you need the 50mm or can you do with a bit longer, the FA77 limted for example might be a better lens for portrait and a bit longer you've the Zeiss 85m.

K10D I'm glad you didn't took my comment as an offence, was just applying that the matter is not as simple as just a faster AF there is much more to it

You can't really lay your finger on the matter why the SDM is quite slow where for example the Sigma version is faster.
For me the AF speed is also not a problem with macro or portrait work fast AF is not needed at all, only for wildlife and most forms off sport a fast AF is better and for the kids playing in the yard for the rest a bit slower AF is not a problem.

To be honest I think we are making more problem about it then it really is.

If they want a good AF system they should copy the one of the D300 with that tracking system, let's hope things will be improved with the upcoming camera's the build quality of the K7 is at least good so a newer sensor (not the K-X type please) and newer AF is just all it needs.

Uploading is done with the same program that organize them on date on my PC and the program doesn't look at Folder names it does look at image names so if there aren't duplicates there it doesn't matter what the folder is named.

I find it too time consuming to do it by hand and I always manage to find things while there are on date.

Indeed, if they could price it close against the hig-end FF market then I could see them steal some market from that certainly of the ones that can't effort a Hasselblad so bought a FF instead, those shooters might be tempted.
Also for example a student or someone just starting his own studio, if he they could choose between a Nikon D3 or a Pentax 645D then for some it's a easy choice hopefully. Pentax also has a "name" in MF land and therefore also some trust, Canon or Nikon just can't bring out a MF camera for that reason and like said the FF market is dominated with Nikon and Canon, Sony is trying his best now though but is having a hard time I believe.

I at least am considering going to get a photography degree so if an MF would be in my reach I would get it.

Ah okay, like said I organize everything on date and time so it doesn't matter what folder or numbering I used and then I can TAG the photos or put them in a separate folder since they are all organize on time I can simply pick out the right ones.

It's just a matter on how you do your organizing on the computer.
I'm glad you found a solution to your problem

Aye, the slower the better.

Regards[/quote]I would just say users error, you just need to know when the press the button
But honestly though you can't prove the photo is out of focus because of slow AF neither can I that it was user error.

Then again Daniel did manage to capture these... link

Well we could then start an argument then that the slower AF was more accurate

I think you've two ways of numbering, one is camera based and the other is sd-card based so to say. You can tell the camera to forget the number for example.

I've my folder based on date but the image number is based on clicks so I can have the same folder on two cards but I'll never have the same image number. When I upload them they photos will be placed on date and time.

How do you organize your photos on the computer?

The Pentax ones work for sure and you should be able to buy them or order them at any shop that sells Pentax.
Since we don't know where you live it's hard to say where to buy one.

Good one, I find it so hard making fish tank photos
