I now own 3 Pentax SLRs - a K7, *ist DL (as of today) and a Spotmatic F.
On shooting some test photos after getting the DL home (with the original kit 18-55 zoom)- I took some pictures (all RAW PEF) around the garden and indoors - and those 6mp shots look darn good! They seem to have a cleaner "grainless" quality to them. Is it just because those sensors had much bigger pixels? Even the 3200 pics look as good as some of my K7 shots.
I got the DL as a back-up body for some weddings, but now I'm thinking of checking a bit more that it may be better at high ISOs for some indoor work.
Yes it has a plasticky clacky mirror noise, no AF spot in the VF and it is slower - but image quality is surprisingly good to my eye.
Anyone else done a similar comparison or had similar thoughts that those older "low density" sensors may be better than what we have now?
I'll try to upload some shots for comparison in the next day or two.
