K5 Firmware V1.03 released
Mmmmm I did a couple more tests and whilst its better its by no means perfect. I'm finding similar to Smeggy around EV2 now LV is still spot on, TTL is still out of focus.... So a little bit:) and a little bit :(

K5 Firmware V1.03 released
AFAIK, the K7 & K5 have colour temperature adjustment for the phase focus. For me the K20D would miss focus in low level tungsten light. The K7 seems absolutely fine. Might be worth bearing in mind that when doing your low-light tests. Try with both tungsten & halogen if possible, or even with d...

EOS 600D and Pentax K-r image comparison
I have my suspicions about this test. The Canon looks sharper, but the Pentax doesn't look in focus and at f/9 that takes some doing :shock: Against the K-5 it's the same? The Exif according to Photome does not recognise the lens on the Pentax, so I suspect it's a 50mm f/2.8 Sigma :evil:

EOS 600D and Pentax K-r image comparison
They should use a sigma 50mm that one is available for all brands i believe so you take one random thing out of the equation. I think Imaging Resource use the Sigma 70mm Macro on all their camera tests. They don't seem to have done the 600D yet. They also take several shots to get the best focus.

K-5 1.03 versus K20D AF tests
OK folks, here's today's tests between K20D and K-5 V1.03. I tested both cameras both my FA50/1.4 and Sigma 30.1,4. Aperture for all tests was F/1.4. I first tested in daylight, around EV9 and made sure the AF for both lens was properly calibrated on Both cameras. Interesting to note that I need...

K-5 1.03 versus K20D AF tests
Very thoughtful of you. I have every confidence that SRS will be able to help you, they've always been very polite and helpful to me in the past. Back in Jan, when i bought my K5, i had to wait 3weeks due to short supply, completely not SRS's fault. But i desperately needed a camera by Sat 29t...

K-5 1.03 versus K20D AF tests
Smeggy, unfortunately the tests I did last night with my fast lens showed a similar FF still. I think not as pronounced but still there. LV however will still nail it spot on. :? Let me know (by PM if necessary) how your discussions with Chris go. :wink: Gary is it possible you can do similar tes...

K-5 1.03 versus K20D AF tests
As I understand it LV simply hunts for the best contrast, so it is based entirely on finding maximum contrast on the sensor data. It doesn't need to know anything else. If LV could be used to provide the AF correction that would be brilliant - you could just run a few tests and the AF data would...

K-5 1.03 versus K20D AF tests
I don't know about "naysayers" but it pays to be vigilant about the methodology of users. Some will be precise and obtain good results (that is, good in the sense of reliable) and others will vary down to the extreme where fundamental flaws are not even realised. Add to that the increasingly wide...

K-5 1.03 versus K20D AF tests
I haven't bothered testing mine for low light FF problems because I rarely shoot that sort of stuff but installed the new firmware last night and then took a couple of shots to see what's what. f1.4/ISO 3200/1/125 First picture was with liveview using the 50mm f1.4 and have to say it was as sh...

K-5 1.03 versus K20D AF tests
Today I found that installing the new firmware has made a lens which was focusing perfectly with 1.02 need an adjustment of -8 under 1.03 to focus correctly. Mike-P exactly the same with my 50mm f1.4 - LV is perfect, using the viewfinder is ff...

K-5 1.03 versus K20D AF tests
One thought is that this may never have been any different. No magazines have reported this as an issue, and it only becomes one at very low EV values. Before the internet, this would just not have circulated and it would have taken a very long time indeed for any issues to become common knolwedge. ...

K-5 1.03 versus K20D AF tests
I think I'll say that firmware 1.03 is actually a lot better than I originally thought. I have had to recalibrate my lens again (a couple are different from under 1.02 :?), but I am now getting almost perfect focus in daylight AND low light. I have even just had my K5 take a photo at -0.4EV.... ...

K-5 1.03 versus K20D AF tests
Smeggypants, love the work you are doing, you are helping us all. I don't have a K5, I went the K10 then K7 and I'm waiting for the K3, but anyway, the original images you posted, seem very dark, not questioning the focus, just wondered why they weren't a bit brighter ? If it was a white card ...

K-5 1.03 versus K20D AF tests
You almost seem to be taking the position, John, that since before we had digital cameras and the internet (and hence the ability to analyse and communicate problems such as these), we wouldn't have known about the problems, therefore we shouldn't be making such a fuss now. No, I didn't say anythi...

K-5 Sensor Stain - Grey Imports..!!
Sorry to raise another K-5 sensor post and apologies if this has already been covered. Went into my nearest photographic shop this morning. They are Pentax Pro Dealers. I wanted to know their best price for a K-5 body. I then asked about the sensor stain, wanting to make sure if I bought one it wou...
