No I like the impression you are looking at a never ending ribbon of images... perhaps a middle way would be if the images either side faded to black if you stay on a shot for more than a few seconds, but then faded up again when your mouse got near the arrow button. Reckon that would be pretty slick!

You lucky person. They could do with a smidge more post-resizing sharpening, but they're very nice. I like the framed crab (although the bokeh's a bit busy - perhaps playing around with gaussian blur could help?), and the shape made by the pelican (a shame that one's a bit blurred though).

The OP was specifically interested in whether the K5 would equal the IQ he gets from his Canon 5D, so....

It's a relevant comparison!

That's great, but I guess most Pentaxians, when they talk about wanting to use their Pentax lens collection, aren't talking about C-mount lenses!

If you leave the 'resample image' box checked, the image will still be 300ppi, albeit it will have been 'blown up' in photoshop using interpolation.

To check image quality, have a go printing it on A4 - leave the 'fit to paper' box unchecked in the printer and you will get an A4 sized portion of the overall image. Then put the image on the wall and see what it looks like, imagining it is part of a much larger print. Remember for big prints you will take a few steps back so don't be too critical of what it looks like close up

Have Samsung caught up with Sony in terms of sensor design?

This is what I'd probably do - (in the 'Image Size' command, within the 'Image' tab in my version of PS): Untick the 'resample image' check box and type in the image size you want, in cm. The resolution will adjust itself accordingly and as long as it's over 200ppi you're fine.

But if you want to retain the 300ppi resolution, leave the 'resample image' box ticked and select 'bicubic smoother' from the drop-down menu. Sharpen the image slightly before printing if you wish.

'Resampling' means interpolation - PS intelligently adds new pixels based on the existing pixels either size. This can reduce sharpness, hence my advice on sharpening.

The K5 is closest in IQ to a full frame digital camera, probably at least as good dynamic range and ISO performance as the 5D, if not better. All Pentax's cameras will 'crop' images from your lenses, making your 50mm have a field of view like a 75mm lens. You will also struggle to get quite such narrow DOF.

No. 1 is cool, would have been nice to have his whole arm in shot though. He was close wasn't he?

He looks more like Zelda from Terrahawks every year

(I know there's an adapter for the Q too, but the crop factor is ridiculous)....
