Hi David and Karen.
I have never conversed with you before today, but thanks for the very nice goodbye.
On the Kiwi Thread here on the forum we have a member/participant who used to shoot Pentax, but swapped to Nikon some years ago as he semi-professionally shoots night, under lights rugby - that is a fast moving sport. Nikon was as better answer for him and what he does. He is still welcome and still comes in to say hello on occasions.
Like others above, can I suggest that is ok to stay, this is a pretty friendly place, and you would still be very welcome.
Friendships formed, even online ones, do not disappear just because you brought and use a different brand of camera.
Pentax Forum is a community, and you are part of it
Just my thoughts....
Ross
