Which new body?
IMHO the FLUcard is a gimmick. For a flagship body released in 2013 the absence of built-in WiFi is a total mystery to me. The FLUcard adds considerable cost and a potential for failure [as do all SD cards]. I'm also very concerned at the large number of people who have experienced the 'machine gu...

K5 just isn't really cutting it in low light
I tried the 6D before buying the D600, and my thoughts were the D600 was better then the 6D in every way apart from the wifi option which doesn't concern me much and I never got on with the D600 at all. Then when changing to the Sony A7 which I still have for the time being I again looked at the 6D...

Smeared greens/yellows from K3
using lenses that aren't sharp enough for 24mp. I'm dubious of this personally, believing that a crap lens is crap at all resolutions. The only issues I expect would be using on different sensor sizes, where the sensor 'looks through' differing areas of the whole lens. A sensor size (ie APS-C) lo...

Smeared greens/yellows from K3
The aircraft window is not only part of the optical system, but also smeared, abraded and maybe or maybe not clean. It's not an optically perfect view and it's a bit like using a filter of unknown properties and quality on the front of the lens. We know that some lenses don't like filters very mu...

Smeared greens/yellows from K3
I've added the post I put to David Storm's query on my thread in the Classifieds here as it's probably a more appropriate place for it than the Classifieds section.... David, I'm still trying to get my head round some of it, and will post more detail when I have. I think I'm dealing with effect...

Smeared greens/yellows from K3
I couldn't resist commenting despite knowing nothing. I agree with Chris A that I see lack of detail rather than colour smear. I'm presuming that when a sensor tries to replicate the light concentrated on it by a lens it will average out over an area of limited definition. You also talk a lot ...

Smeared greens/yellows from K3
Thanks Chris. But that does suggest that he is comparing pictures that in effect have much greater zoom variance and therefore will have less detail due to optical limitations. Not sure about *much* greater. If you take 100 pixels from a K-3 sensor and put it on a monitor, it will occupy the same...

Smeared greens/yellows from K3
You make it sound like a small difference. The K3 has 50% more pixels than the K5, crammed into the same physical space. How that works in spacing I don't know but comparing pixel to pixel it is a big difference in image area. 3.9um for the K-3 vs 4.8um for the K-5. The K-3 sensor is a touch smaller...

Smeared greens/yellows from K3
Well as Steve has chipped in claiming no knowledge so will I :) I just wondered if this could be a different issue to do with cabin pressure causing issues with the 24mp sensor that it doesn't in the 16MP sensor of the K5 or GR? Have you tried the simulated AA filter switched on? It might have...

Smeared greens/yellows from K3
If it had focused on the window nothing would be in focus, Chris. I don't know what "distant view" means in the exif. One reason the GR shots are totally unaffected could be because I set the focus to infinity, so the camera is not having to focus at all. I have seen yellow smeared in a couple of im...

K30 - viewfinder alignment problems?
p.p.s Not the same lens as I had on K10D, that was a Sigma 17-50 I think, something like that, and I sold that camera about 5 years ago. The menu option to adjust focal length for SR is not available, greyed out. However, I did find an interesting menu option (I find more features every time I...

K30 - viewfinder alignment problems?
Looking at the vignetting in one corner it looks like the sensor is misaligned with the image circle. I'm not sure how much travel the sensor has in the X and Y plane but the solenoids should hold it central and it looks liek that isn't happening? when you get conditions when the problem occur...

K20D sell or keep?
looking at Ebay completed prices, around £150-200 ish Thanks for providing price estimates for my K20D! Bjorn. "Is there any point in keeping it?" It depends if you are a collector of redundant things or a practical use it or lose it person. Personally as I have bought new I have sold on my Z1p, ...

Pentax K-3 versus Pentax K-5 IIs
Both will give you significantly sharper images, I went from the K-7, which has the same sensor as the K20 to the 5iis and was stunned by the improvement and I have since upgraded to the K-3. Personally I would choose the K-3 because of the additional speed and functionality, although, apparently, t...

Pentax K-3 versus Pentax K-5 IIs
I've had a K-5IIs for about 18 months and a K-3 since last November. For me, the K-3 is the better camera and gets used a lot more than the K-5IIs does. It's not so much about sharpness, although the K-3 does edge it due to the higher pixel count. It's more about the WB, the metering, the warmth ...

Pentax K7
Yes, I do have a K-7 but I haven't got a K10D so I can't comment on the benefits of upgrading. I upgraded from an *istD & that certainly was beneficial in some respects. More Mpixels, the K-7 wakes up faster, focusing & shooting more quickly. The K-7 is better for Street than the *istD was. People ...

Pentax K7
The K-5 is a better upgrade without a doubt. I still happily use the K-5, which was a sea change in performance. However, the K20D and K-7, using the same sensor as your K10D, will offer a useful jump in quality in many respects. I didn't upgrade to the K-7 but took the path K10D>K0D>K-5. The K20...

Pentax K7
Lets remember the K7 is the same body and with identical control features and processing options, as well as accessories and connections available. The Prime processing engine was a significant advance over the previous flagship model, and the model introduced the LV and video functions as I underst...

Pentax K7
I'd also mention the K-30/K-50 option, as I have one :wink: :oops: Point I'd make though is that it's the same sensor as the K-5 and offers some newer options like focus peaking on live view etc. There are some down points for sure, and the sensor is not used in exactly the same way, but funda...
