Ive finally made up my mind.
The images you've posted are not the best for assessing focus accuracy. In the third one it's not clear what you are trying to focus on and in the fourth one almost everything is in focus as it's a wide-ish angle shot with subjects at a distance and it would be quite difficult to get that one out o...

Hi Suzanne, I thought you were asking for opinions on the focus accuracy, based on the content of this thread? Regards David

In the morning I will get something to focus on and take some shots, then I can post them

I think you have been reading too many forum posts about front/back focus, I would recommend you spend a month getting to know and enjoy your camera before you make any adjustments.

KX v K30
i traded my KX for a K30 last month, the weather sealing was the main point (and the price of the K30 being ridiculously low), I havent shot anything yet (unfortunately), but the two main differences I see: - K30 is MUCH bigger/heavier than the Kx, didnt i'd care but actually i do - K30 has 2 di...

K30 firmware
You have extracted the file to the root of the SD card (and not just copied it over as a zip file?) Yes there are 2 files in the extracted fold, I have tried both of them individually and the folder with both of them. Files are FWDC215B.BIN.cpgz & FWDC215B.BIN FWDC215B.BIN appears to be the corr...

K30 focus inaccuracy
So, came back from holiday, looking at pictures taken with K30 bought recently and plenty of them are not in focus with clear front focusing. But some have focus correct (significantly less then 50% overall). I did run a quick test just before travel and applied front focus correction to particular...

K30 focus inaccuracy
Hmmmm . . . I too am a new K30 owner and have, on occasion, noticed some pictures out of focus. I had assigned blame to the operator (me) and probable rookie errors. My most used lens is a Pentax 18-250. How did you perform your tests?

K30 focus inaccuracy
You can check focus accuracy using one of many focus charts, one example: http://pentaxdslrs.blogspot.co.uk/2008/06/part-1-autofocus-adjustment-for-pentax.html Or just using whatever you have around, that will give you a chance to "read" results, look at the chart and you will get the idea.

K30 focus inaccuracy
Thank you! I hadn't noticed the issue with my K10d. And, I may not have an issue, just becoming a bit more aware of details.

'SR' on or 'SR' off?
Hi all, After my slightly disappointing first time out with my new K5 II last weekend ( see link below for my comments) https://www.pentaxuser.com/forum/topic/k5-ii---first-shots---birmingham-wheels-38032 I went back to Birmingham Wheels Raceway last night ( 17th Nov ) and decided to shoot ...

5 AF points or 11 ?
My understanding is that 5 are more suited to shots where the object is typically going to be in the centre area of the viewfinder. Planes at an airshow - that sort of thing. I use only the centre one anyway. I focus exactly where I want and then compose and then shoot.

One for me. You can use focus lock at any time anyway.

5 AF points or 11 ?
I think what most seem to find is 'not much'. The last time I saw this discussed the most common advice was to 'focus lock & recompose', an age-old tried and tested technique. One thing to consider with this though is your preference for exposure bias at this point - we have the option now of linkin...

5 AF points or 11 ?
I use the centre focus point, but have started using the expanded focus point on my K30 for moving objects (sport), seems to work OK.

FOCUS LOCK makes it easy to go with one point!

5 AF points or 11 ?
Even though I only use the centre focus point myself, I'm aware that lock focussing and recomposing can alter the distance of the subject and thus throw focus out. This may not matter much on smaller apertures, but with wide apertures this may ruin your shot.

5 AF points or 11 ?
It's a fair point Smeggypants. How much it affects the point of focus is hard to say - when diagrams are published they tend to be exagerrated to make the point, but the actual arc involved in many situations is part of a huge circle and we could be in mm territory. Focusing isn't that accurate anyw...
