You sure?
I mean I've use my SDHC cards cross brand ones while photos or on it without any problem.
Also Formatting does not create the folder onto the card, it's with the first photo the folder gets created, but you're right if you format the card inside the camera that you also see the folder.

Those are my findings but with a different camera though.
Panasonic point and shoot and Pentax K10D.

The first shot of mine, the mono of the little girl was taken with the DA40mm at f/2.8 so yes any 50mm lens would be very capable to do portrait on the APS-C sensor because it's 75mm equivalant AOV and the classic portrait lens was 85mm on film so you can't get it much better.

But like you read all over this topic it's about what you're used too, I would rather have a slightly longer lens but that's me and has nothing to do with the lens it self.

Thank you ALan, seems like the only good match for the DA*50-135 is the DA*16-50.
I hope they will be happy together

That's what I suggest in my first comment and since it's the fourth time I would suspect Pentax must do something to ease the pain but I didn't get any response on that so I think he wants to fix it himself or want to get another camera brand?

With 18cm it would be 1:5,31 with 18,5cm it would be 1:5,53 sadly not much macro but close enough

24mm you only need a small extension tube or reverse mount it and you can get very close.

No doubt about it the K-X is the better camera, there is a newer sensor in it and newer hardware while the body is the same.

There is also the K200D, it has the same sensor as the K-M but it has a better body in mine honest opinion.
It's still small but slightly larger, it takes AA batteries, it's weather sealed, has top LCD screen, AF brackets in the viewfinder and you can buy a battery grip for it.
The battery grip can be handy when you want to use heavier/longer lenses since it would balance the package a bit better.

I'm sure you would than buy a MF camera and than start to buy all lenses for that

Thank you Ian, one named this under the word isolate the model. I believe you two mean the same and this was indeed an aspect I didn't thought about but is certainly true.

Also on digital? I'm sure I would love the lens

Thank you John, still it's hard to see it for me but we are always the most critical when we judge ourselves.
When I see the 4 photos so side by side I do feel the same air a bit around them but strangely there is almost a year between each shots, guess there is something that I couldn't see before.

I'm have the same problems ^^

Is there any reason for you not to include the Tamron 17-50?
Some forum members here have one and I've read good feedback from them.

Also the Sigma 17-50 is very new and not even in the stores yet and spend last night finding a review without success so no one know how that lens is

I need a lens quite soon so can't wait for the Sigma so I'm most likely going to get the DA*16-50 if it does feel alright in the shop if not I'll wait for the Sigma 17-50 and try out which one is the better lens.

@Ajbets - That's not so good to hear, luckily I can almost throw a stone through the window of the Beukelaar (representative of pentax in the Netherlands) so they better give me a good one

@Alan - I must confessed that indeed the range of the 17-70 would make it the ideal walk around lens but Since I've the DA*50-135 and enjoy using it I don't mind switching. From what I understand you've the DA*50-135 and DA*16-50 is it a good match and do the lenses feel the same?
