Tjompen1968---It's hard for me to imagine that you are not serious with shots like those...but that's what the man said, so I guess you were just "fooling around" and accidentally got those shots on a random snap?
There are so many fantastic wildlife shots in this Forum's many locations that it would take months to view them all...and most of them were shot with a Pentax.
I'm not a serious birder, not even a serious shooter....I shoot for the fun and joy...but if I was I would not hesitate to shoot Pentax.
Even ISO 6400 works for me with Pentax.
This dove looks like a chicken to me?
Anyhow, I have a lot of fun shooting birds....

For those that are serious, I see serious Pentax shots......they are not hard to find on this site!
