Image quality of a K-5 vs a K-r
Hi, It's a strange thing to want to do. If you can afford the top model you buy it if not you buy the KX and later the KR like me. Like everyone I've seen the price drops of the K5 and like all camera owners I always fancy something better. Personally I love the KR which so far has delighte...

Image quality of a K-5 vs a K-r
Thanks, but I'm not quite getting my point across very well! I'm fairly knowledgeable with regard to the specific differences, but a pro camera shot generally looks better. Now in this case is it the extra resolution, the sensor is better, the software is better or what? It's not because it's weathe...

Image quality of a K-5 vs a K-r
Badly phrased - you know what I mean mdc!! I'm not talking photography skill, artistic quality, here, I'm fully aware that some of the best shots I've ever seen haven't come from expensive cameras. The point I'm clearly failing to make is that if you line up a K-r and a K-5 side by side on a tripod ...

Image quality of a K-5 vs a K-r
The difference between the K-5 and the K-r, image-quality wise, is that the K-r has a 12.4mp Sony Exmor sensor, and the K-5 has a slightly newer 16.2mp Sony Exmor sensor. That's pretty much it. The newer sensor seems to have better low light performance and better sharpness.

AF microadjustment
Does any one around here really understand why this is needed? Because if so, I would dearly love to understand a number of things. Firstly, and most importantly, how can the way the AF system works out whether the image is in focus or not, give a different result for different lenses? I co...

AF microadjustment
Contrast AF works by doing more or less what you do as a human - it changes the focus by analysing the contrast of the image on the sensor. It doesn't know how far to change focus, but it keeps refining it until it is as sharp as it can get it. Phase AF is an entirely different kettle of fish. I...

AF microadjustment
Actually this begs an interesting question regarding MF lenses. Given that it's not the camera moving the focus to the calculated point, but the operator, would you expect the BF/FF errors not to occur? Or at least be consistent from lens to lens on the same camera? Errors will still occur, si...

AF microadjustment
Why would a manual focus lens need the AF adjusting? We turn the focusing ring until the image in the viewfinder looks sharpest and that's it. Because the AF confirmation hexagon is just as useful with a MF lens as it is with an AF one - arguably more so in fact, since as you said yourself, many peo...

K-5 electronic level
Mine is consistently accurate. The one that went back for sensor staining also had an accurate level. I use it all the time.

K-5 electronic level
My six month old K-5 level is ok at the moment. However my K-7 started to creep out in the horizontal plane just after a year and is now around three bars out. In the vertical, portrait, plane it is still fine. I noticed as well that the auto horizon correction function, which I have never used,...

K-5 electronic level
I noticed as well that the auto horizon correction function, which I have never used, went out at the same time so must use the same sensor. Yes, I'm sure it does. It must rotate the sensor by the amount the level detection thinks it's leaning. [sigh] This is a classic example of the way P...

K5 destination or migration?
The D700 is no doubt an excellent body. However other than the size of the sensor (and the added DOF control) there doesn't seem to be any advantage over the K5, I doubt its as good in low light. Don't forget that you would need to factor in the cost of FF Nikkor lenses- have a look at the prices...

K5 destination or migration?
I have not played around with a FF camera but have with a Canon 1d something with the aps H sensor (the 8 million pixel one) with an 'L' lens - I studied the shots taken and felt that I could not see a reason to even consider moving :D

kr being discontinued..
As you know B&H are one of the most important camera retailers in the US. I think it is highly unlikely that they have somehow got the wrong end of the stick on this. Presumably a new model is on the cards, and that could also go for the K5 given the way pricing is developing; FWIW, Sony seem to...

The Kodak sensor business has just been sold, so those new owners will also be keenly looking for new customers. They already deal with Pentax for the 645D.

The Kodak sensor business has just been sold, so those new owners will also be keenly looking for new customers. They already deal with Pentax for the 645D. I read a report Lieca was dropping the kodak for Fuji's sensor, also that Canon views the new fuji sensors as a serious threat to thier FF sens...

Samsung going back to Pentax SR instead of it's own ois system... ... so it begs to reason... given past rumours of Samsungs medium format system... is it possible that rather than pay patent royalties, they worked out a deal to discount sensors for Pentax's evil medium format camera? samsung ...

Noisey SR in LIveview/Movie
DavidRobinson, you're almost certainly hearing the SR moving the sensor around to compensate for your hand motions. Especially if turning off SR makes it go away, or if it isn't there if you place the camera on a tripod/table.

Noisey SR in LIveview/Movie
Are we talking about a barely audible whining noise? I hear it on my K7 sometimes. I always assumed it was something to do with the motor / magnet / whatever! that holds the mirror up in long exposures / live view / video. You can definitely faintly hear / feel the motor moving the sensor in live vi...
