Upgrading from K20D to K5 - is it really worth it?
The K20D was the best camera I had ever had, I could not see any reason to upgrade to the K7 As I am not really bothered with Video filming. But when the reviews of the K5 came out, The better sensor and better noise control made me drool so much I got one and kept the K20D as back up and for the o...

Upgrading from K20D to K5 - is it really worth it?
Anyone who uses Pentax knows that lenses from previous generations of cameras can be use on the current DSLRs, unlike Canikon who decided to switch mounts on their followers and thus these found that they cannot use the old lenses on the newer bodies because the companies decided to start a new moun...

K5d or D300s
Thank you , John. ten quite right, I've been comparing the two Dslr Dpreview in and saw that the D300s, has no great advantage in the K5, so I adquerir the K5. Also I've read here in the forum of some problems in sensor K5, but the Pentax is to repair it at no cost to their owners. I hope withi...

K5d or D300s
The Pentax KR also has 12mp in a low noise Sony sensor. Very quick at 6 frames a second and the AF is much more intelligent and quick than say the KX which preceded it. I've not seen any cameras which have the compactness and ergonomics of Pentax in APS C. John's right though we're all biased! :-...

K5d or D300s
Nsantos, the sensor issue occurred in an early batch of cameras, and was fixed promptly by Pentax. It has not recurred. Piotro is probably right in saying that the Nikon, when equipped with the right lens, may be faster than the K5. However, the right lens will not be cheap, and the gap is much...

K5d or D300s
I have recently been comparing these two on DPreview, as I want to upgrade from a KR, the K5 swings it for me (also I'm loath to change systems). But assuming sensor issues have been sorted, I will be upgrading soon.

GX 20 problem
I took a few pictures tonight on my GX20 and noticed a thin black line running from left to right halfway up the image. Is this a faulty sensor? Has anyone else experienced this. I've half a mind to send it back to Samsung as I would expect a camera to last more than 2.5 years with only about 7000 c...

GX 20 problem
If I remember correctly I have seen this fault a few times on the forum with the K20D (although the line went top to bottom) and it turned out to be sensor failure.

GX 20 problem
Hi I will try a different graphics card but the line is visible on the screen and then on the file when it appears on the computer. I have a horrible feeling it's the sensor and I think a battle of wills with samsung beckons. cheers though for the input b

Focusing Screen for K-r. Any recommendations?
Hi, I have A Kr too and it's the cheap Pentamirror that gives less light than a prism as well as the smaller sensor format. I've had screen out for cleaning on a KX and now my KR when dust gets above the screen. Don't know why they classify them as not changeable as they clearly are, albeit wi...

Focusing Screen for K-r. Any recommendations?
Figure 3. A phase detection AF system uses a series of mirrors, a small sensor at the bottom of the camera and a processor to calculate precise focus. AF system Photographers are used to trusting auto-focus — even on action shots where the shooter is following a moving subject. When a DSLR's...

K-r manual focussing
Hi Dan, If it's subject moved I guess you are referring to telephoto of wildlife. I have the KR and when using my 55-300 lens at full telephoto I've found a lot of practice and patience is required BUT the results are worth it. I use high ISO as the KR sensor can deliver 800 as default 1600...

Keep my new K-r or upgrade to K-5
One of the things I couldn't do without is the front wheel on the K-5. I absolutely love being able to control ISO with the front wheel and Aperture with the back on Av mode! Sooooo convenient. In your case though some glass is probably a better investment. I really liked the feel of the WR18-55 ...

K5 reaches the end of the road...
Had an A77 which is what brought me back to wanting the K5 again. Pentax will have to work very hard to get the image quality right if they indeed choose to use that sensor. I think ALLUDED TO T WHEN frst came back last month. I owned a Canon 7D Which I just couln't get away with then a Nion D70...

K5 reaches the end of the road...
Hmm, just doesn't do it for me I'm afraid, too much crossover with the 1Dx but then a different sensor??? (Video related?) Frame rate is quite high which will canabalise some 1 series sales too and it's 600 quid more expensive than the Nikon which has too many pixels to hold steady anyway, niether w...

K5 reaches the end of the road...
The end of the road for my k5 (and Kr) will be: 1. They breakdown and are not cost effective to repair 2. Pentax - (who probably by then will be called Penapplemicrotax) release new models that so far outperform these gems that it makes it impossible to ignore them - once they have sorted out t...

K5 reaches the end of the road...
I'd like to think I'll feel the same way but... I know what I'm like! I love the image quality of the K5, it will be hard to replicate but if they simply used the newer 16Mp sensor bingo! Again We'll see... I like the idea of a Silver K5, very reminiscent of the limited Lx, which I thought wa...

K5 reaches the end of the road...
I am almost sure that the one on the picture is a " dummy". Look at the IR sensor. Looks like painted.On the real one the sensor is recessed because of the bigger grip. In reality the silver K-5 doesn't look like painted. The feel/look is more like solid metal. I've got the silver and the black but...
