This is about the easiest way...... http://ricehigh.blogspot.com/2012/01/focus-adjust-k-5-and-pentax-af-lenses.html - This has been the most succesful for me and leaves no ambiguity. My lenses are all now spot on for the first time. Interestingly my zooms did not need any adjustment, yet other...

I don't think the 50 1.8 has a focus scale same as the 35mm 2.4 though?

I really dont understand half of that In simple terms you put an object (i used a cereal bix) 2 metres away from the sensor in the camera which is marked by circle with a line through it next to the top LCD screen Using live view half press the shutter button so the camera focuses on the cereal b...

The reason im asking is that I took it to the park this morning, I was trying to get pictures of the dog but didnt seem a to get a single photo that had him in focus when moving ect.... it also doesnt seem as sharp as I thought it would.

ahhhh no, none of my lenses have got any focus screens on them

Try some still pictures first and work from there - catching animals is about the most difficult thing you could have chosen to start off with! Lenses don't have focus screens, so back to basics?

how do I do that ? i think it seems to be a back focusing issue. I kept trying to get the dog in focus and although it the camera was focusing on the dog he always came out less focused than the background

If you look in the 'Add a Comment' box below, you'll see 'Image'. Click it, and it'll open another window that'll let you link to an image on your computer or a web-site. BUT, nothwithstanding your previous experience, take a shot of an inanimate, static, object if you want to test the focus accu...

You may have missed focus Tongue and nose look pretty sharp Looks ok Trouble is they're all low res and don't have intact exif data. I suspect it got stripped out when you down-sized them. Are the originals on Flickr or similar? If so, could you link to them please?

Ive finally made up my mind.
When you use put the camera to Live View and press the AF button it will focus the lens to the sensor using the contrast to decide if focus is found. This system is not as quick as Phase focus but very accurate. Phase AF is much faster and uses a pair of small AF lenses and if these are ever so sli...

To add to what Steve said; Menu - Live view - Auto focus method, - Face Detection, Contrast Detection, Phase Matching. Choose Contrast Detection.

It's in the manual. You set what type of AF to use in LV. You can also focus accurately in LV using Manual Focus. -

Ive finally made up my mind.
So when doing 'AF Fine Adjustment' ('c' menu 26) and folowing RiceHigh's guide one should be testing in Liveview mode yes? Yes To be more accurate you should test through the viewfinder and not live view when setting the AF adjustment. The idea of first focussing in Live View is to establish the...
