Focus peaking - how are you finding it?
Yes -- I am geeting fed up with being let down by manual Focus on my K10D -- I did some floodlt footbal using my 135mm f2.5 SMC Takumar because of the wider aperture f2.5 and all were OUT -- I have to focus much futher forward than normal and hope it hits the right spot -- then last night I was usi...

Focus peaking - how are you finding it?
Well, I've just used focus peaking on my K-01 to take some product shots with my 50mm f/1.7 for a filter I'm about to post in the classifieds, and it worked splendidly. Using the 6x zoom I was able to nail focus precisely on the words on the filter ring, with the highlights crawling back and forth ...

Spooky! I was typing my last post before Peter's had appeared - both using the SAME lens!!! Time to open the beer!

Focus peaking - how are you finding it?
On the Q it must be hideous because that camera has such a deep dof. I think this may be key. I tend to use focus peaking on lenses that will give a shallow dof (50mm 1.7, 90mm 2.8, 200mm 3.5).

Focus peaking - how are you finding it?
The K01 implementation is good, almost like a dof button, showing in/out of focus areas clearly.

Why would they make the K-30 version worse than the K-01 if it is?

Focus peaking - how are you finding it?
It's exactly the same with both (have tried both side by side in Jessops). I took my own 135/2.5 lens, and the peaking worked better with that than the kit lenses.

Focus peaking - how are you finding it?
I'm glad to read that it appears I'm better off with my Katzeye screen. But focus peaking doesn't cost an extra 100 quid or require shimming...

Focus peaking - how are you finding it?
I tried it further with the Q but I just couldn't get on with it. I can focus better manually by eye.

Focus peaking - how are you finding it?
I think the view is that the Q offers too much dof for effective use of the feature. If you have a chance, look at it on a K-01 or K-30 with a wide apperture lens.

Pentax IQ
However, while we're on the subject of IQ and improvements in camera technology, all I want is improved 'dynamic range'. IMHO digital can't hold a candle to film in that respect. Yes it's wonderful that we can have gazillion megapixel sensors and noiseless images at 200,000 ISO. But very rarely can ...

Pentax IQ
I was taught in the film era to overexpose to capture shadow detail. I never had the competency of pro friends though to manually protect the highlights in the darkroom waving my hands under the enlarger! When I first had digital ten years ago it was point and shoot and then bridge cameras that a...

K-30 disappointment
............ and this one is just a 28% crop with the Sigma at 270mm, f6.3. I use this shot a lot for testing and the edges are usually razor sharp. It is giving the green light and focus bleep and there's not much to confuse it here either.

K-30 disappointment
There's nothing wrong with the shot as such, but 1/200s is a bit slow for the 300mm, and indeed for the bird, which is also moving. The crop is also not helping. I would do a more controlled test using a target such as a newspaper taped to a wall. With a tripod and trying every aperture see wheth...

K-30 disappointment
Dave, I would hazard a guess that some fine AF adjustment is required. I once had a K-x which back-focussed very badly and shots on this camera with my 55-300 were really poor in comparison with the K-m. This was confirmed when I bought another K-x which was perfect. I'm not sure of where in the ...

K-30 disappointment
Have you got one or other of the NR options enabled? I thought my K-30 was soft too (after the K10D, in my case). I disabled both 'High-ISO NR' and 'Slow Shutter Speed NR' and it seemed to improve considerably. Now I didn't do any back-to-back testing, and I don't know for a fact whether th...

K-30 disappointment
I think Dave is referring to focus inaccuracy and lack of sharpness rather than noise? The two shots posted here do not look absolutely sharp to me and I'm sure it's not Dave who is at fault as I've seen lots of his images and they are always sharply in focus. Regards David

K-30 disappointment
I think Dave is referring to focus inaccuracy and lack of sharpness rather than noise? Just to clarify, I was suggesting that the NR modes of the K-30 cause considerable softness. I can't remember if they're enabled by default, but *if* the OP did have them enabled he might get sharper results wit...

K-30 disappointment
You could all be right in various ways! Check back later when I have done some more scientific testing tonight. I would add though, as David has kindly alluded to, I am aware of expectations and limitations with a good deal of experience of the type of shots I have tried in these conditions. I've no...
