Just a question for many who say that they aren't able to use the k10/20 features fully as yet and still learning. Which are the features that you are still unfamiliar with? Having the camera for about 3 months and used it extensively for a week, I found that I had almost play with the camera's features inside-out. Not trying to be arrogant, but may be there's really something I am missing out. Please advise. Thanks.
you will be familiar with the features quickly, the question is whether you are actually exploiting the camera's full potential, and whether you actually need additional features.. to put it bluntly.
do you think > 3fps will improve your photography?
do you think having a full-frame sensor will improve your photography?
do you think having additional features on top of existing will improve your photography?
among many other questions you should ask yourself with regards to "growing out" of any camera model. when i dumped my sony h2 to get the k100d, it was because of the limited f-stop range, noise levels that i was noticing when i needed faster shutter speeds, etc. when i finally bought the k20d after holding back since it came out, it was because the k100d didn't have iso100, and due to a limited lens selection and budget i liked the fact that i could crop the massive 14 mgp output i would be getting, since cropping on 6 mgp output is really painful. there are many factors that i discovered later on, like better DR, etc.. but that is a bonus out of what i was expecting, which is better. however, expecting no improvement and buying.. well if you have the money by all means, i will not tell anyone how to live their lives, but if you have a constrained budget, then perhaps you should tell yourself firmly that no, this isn't going to help and i should brush up and exploit what i have before being able to justify upgrading.
the answers for some people to the above 3.. might not be no.. and they will not be under the BBB virus when they say that. that's fair enough, because k20d is still limited in some ways. but i think for me, it is no.
