I have had or have now 16-50mm DA* (twice), 50-135mm DA* and the 60-250mm DA*, and the SDM focusing motors haven't failed so far, and I've used them extensively. So for me at least, they've worked very well.



Also, I have only had Sigmas that are in spec and haven't failed. My 105mm also took a high fall with the K10D with vertical grip attached mounted to a camera, and continued working only with a filter ring dented <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='' /> So I guess I'm lucky when it comes to lenses.

ROFL... I've got to write this down <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />



And someone ought to combine that with this new Pentax problem:

I feel sorry for the guys actually... if I wanted to buy a second DSLR system to keep alongside my Canons, I'd consider Pentax/Sony, Sigma, Nikon, Olympus... in that order.

Ah, finally I understand Klaus wanting to remove the AA-filter glass from his K5! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />

It is an expensive dry sensor cleaning job.

Which camera combination is primed to give the sharpest and most pleasing images.

just wait for SD1

I can see how the SD1 images will be sharp... but can't see how they'll be "pleasing"...

Maybe some find aliased, moire-ed images with very bad high ISO noise performance pleasing.

Don't mind my stepping in here... I have a soft spot for Foveon actually... I think their sensors are wrongly understood, especially in relation to noise. Like I explained in a discussion relating to the D7000 elsewhere, we're still in relatively dark ages of photography publications (thanks to the incompetence of sites like dpreview). Noise shouldn't be compared between sensors without considering resolved detail (call it real resolution). Foveon images do upscale easily to 3x their total MPs and are detail-wise very comparable to images from Bayer sensors of that larger resolution. Since native Foveon images pack more information than Bayer images of the same image dimensions, we shouldn't be too quick to criticise them for noise before doing that resolution normalisation I mentioned. The upscaling also makes Foveon edges look less aliased and more Bayer-like.



Don't get me wrong... I'm not saying that Foveon's just as good as Bayer sensors... just saying that the way most people compare them is not quite right.



Also about the comment on pleasing-ness was mostly directed at Sigma lenses, more than at Foveon's quirks (e.g. colour shifts, etc.) <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />
