K7 poor image quality
Why I dont know but after 48 hours use the camera went from awfull to excellent. The same has happened to me occasionally when using certain lenses that I might have just bought and tried, bad results for a good few days and then suddenly....Amazement at the great results. And then when looking back...

Lens is the 15mm Ltd which topping out around 22.8mm these days ain't wide at all... How times change...When I set out on the path of learning photography in the 1970s a 24mm was considered ultra-wide and I could only dream of affording a 20mm.....most of us had a 28mm and that was as wide as we c...

In the audiophile community there is the well established theory of 'burning in' variuos compomants, the speakers and amps for example. There is the famous 'musicality' debate about Linn Sondek turntables too of course :) So I wouldn't be surprised if variuos dslr parts including the electronics b...

K7 poor image quality
Well all I can say for the poorly derided K-7 is that I upgraded from a K10 and the quality of my images improved at the same time. I think this was mainly due to the improved viewfinder and greatly improved digital display allowing me to frame shots better. I remember being impressed with the spee...

I was being slightly tongue in cheek but not convinced totally you are right. I wonder if the electrons trucking along from photosites don't make a sweeter path over time, lower the friction and give me less noise :) I believe that was more mechanics of the deck bedding in. As for the el...

Pentax K-5 - buffer limit problem !!!
This is the fastest and most accurately focusing camera Pentax has ever built, easily in line with Canon and Nikon's offerings in the price range. One small disappointment is that the fast focus and 7 fps capture rate makes the camera suitable for sports and wildlife photography, but the camera has ...

So it's a disappointment, but not a problem? Hmm. A contradiction there, methinks. Come back and let us know when you decide which it is. :D G

K-7 focus adjustment
Hi All, I'm off on hols in a couple of weeks, I don't really "do" sunbathing so thought I'd sit down and test/check all of the focussing on my K-7 with the small arsenal of lenses I'll be taking on my travels. Can anyone with some experience of using the in-built focus correction tools give me...

Hi Will, 1.) You might find this link useful There are quite a few different ones but I have found this one fairly easy to use and gives reproducible results. 2.)Probably daylight is best 3.) Yes you can get a pretty good idea from the screen on the camera. 4.) Best to test at wides...

I find something slightly odd in the concept of going on holiday and taking a test chart to photograph...there might be better subjects! :?:

I find something slightly odd in the concept of going on holiday and taking a test chart to photograph...there might be better subjects! :?: Indeed... it does seem odd but in the middle of the day when only mad dogs and SWMBO will be out in the midday sun, I thought I might find the odd spare moment...

Pentax user and blogger has a good set of charts. Odd thing to do on your hols, but each to his own. As long as you end up using the stack of lenses you are taking with you, for more than just adjusting the camera.:D

I use one of these ... I AF on a chosen number at an oblique angle, and then zoom in on the preview and check whether it's front or back focussing

Presumably after several tries, focusing in both directions to make sure a good average is arrived at. It may also vary with focal length, even temperature, so being 100% precise won't be possible.
