Originally posted by dsport I found my FA*80-200mm to have some back focus problem with my K20D. Thanks for the build in AF tuning function inside K20D, I manage to DIY without sending back to Pentax for adjustment.
I know there is a focus alignment chart, however I am too lazy to download (actually because I have no printer to print the chart out).
I seem to have best result after adjusting to '+7' in the AF menu.
Here are some shots all taken in wide open f2.8.
Focus are all in the eye.
Do you think the pics are ok in sharpness? Thank you for any comments.
You'll have to get a new one. I know a guy who'll take that one off your hands for $100.00 for scrap and parts if you like. Send it on down...
Your lens is FINE!
You have to stop down quite a bit to get the entire snout in focus at that focal length. Try f=16-22 at that focal length if you want most of it sharp.
And, BTW, we have the same dog! Mine is named Zoe, she's almost 16, and is still quite fiesty and going strong.
Great little dogs, the min-pins; ferociously loyal, atheletic, fast, extremely protective, smart, hair not fur so they are hypo-allergenic, don't eat much, long-lived, very few visits to the vets (statistically one of the lowest of any dog) and her poop's the size of your little finger, so easy to pick up after.
Mine's greyer than yours now.
Cheers,
Cameron
