hi stefan and matt sorry the shots are not the best examples,
i have just done some random shots around the house and all shots come out ok(still think the camera bumps the iso up for no reason)
but i think one of my problems in all honesty is i have been usin my d300 for a while and im comparing and prehaps i shouldnt be, the nikon i can set at f10 with a shutter of 320/sec and auto iso 100-1600, and around the house it very rarely goes over iso 800,
example both cameras set on 160/sec f10 nikon selected iso 600, pentax selected 1250.
i found the k7 seems to struggle on faces and almost remove any skin tones when usin flash..
i think my best bet in future is to use full manual iso 100 f8 180/sec


one other thing learnt is either my pentax 50-200mm is longer than 200mm or my nikon at 200mm is more like 150mm.

hi stefan it is set to 35mm and i will try set at 85mm tonight and see what it does. Matt i didnt realise that the samsung sef 36pzf was built before digital i suppose the 35mm should have give it away. Thanks

hi matt will read properely when i get 2 mins. I was expecting the same exposure. And in the test with the pop up and the samsung why is the samsung not so bright. I find using manual f8 shutter speed 180/sec iso 100 is fine for most shots. It tends to be to bright on people faces otherwise

hi stefan what i mean by slow adjustment is that the k7 has a setting for the iso to bump it up faster or slower it has 3 setting slow normal and fast.

also when using av mode with the lens at 200mm about 8ft away from the subject with a shutterspeed of 180/sec and iso 400 and f4.5 it comes out slightly darker than the same test with an apature of f8 surely the larger apature should be brighter.

after having a play im still convinced that the camera is upping the iso up for no real need even with slow adjustment selected., a shot that can use iso 100 with no problem and its using iso 1600,

Glad you solved it... now comes the question what caused it

I believe you can use Flickr with EXIF data or else try photobucket that's also free.
hi stefan which picture looks better exposed to you.
also these were from flicker. and im also with photobucket and both remove the exif data.
#2, #1 is still too dark and even #2 could be slithly brighter.

As for the exif, did you resize the photo maybe or used a program of some kind?
stefan no resizing, flicker does that. also you say 2 could be slighty brighter.
1 to me looks to dark and 2 looks a tad light.

Well, I guess I must have the same settings, as my K7 behaves quite the same way... (see my previous post)
can you post an example, im happier with the results im getting(but i still think iys bumping the iso up for no reason.)
also i have adjusted the flash manual to -2 and up to =1 and it does make a big difference.
