I'm a long time PF lurker that decided that the delivery of new K1 meant that I really should join.
I started taking photographs in high school nearly 40 years ago with an Olympus OM-1, shot a variety of cameras over the decades and switched to Pentax about 9 years ago. I picked Pentax (K10D, K5, and now the K1) over all other cameras because of the level of controls, IBIS, rugged body, and compact size. I'm not a believer in brand loyalty but would not shoot Canon, Nikon, Sony, or the others if meant I had to give up my Pentax cameras which have helped me take tens of thousands of images while surviving untold miles of hikes, rain, sleet, snow, rocks, and even ocean waves.
Although photography is my hobby, my professional background includes hardware & software engineer of electro-optical and scientific image processing systems. I've designed high-resolution large format scanners (2.3 gigapixels) so I'm very familiar with optical system design and sensor performance (which is another reason I picked Pentax).
I shoot mostly landscape, macro, architecture, abstracts, astro, and the occassional concert or sports photos for friends.
I look forward to my time on PF including Rupert's squirrels, Adam's masterful management, MikeSF's astounding images, Digitalis' technical insights, and the helpful advice, inspiring images, and "vigorous" discussion from all the Pentaxians here.
To christen the new camera and new membership, here's IMGP0001 -- a mirrored-selfie of a K1 with it's new (old) owner. It's not the most balanced composition of not the most balanced subject. (Taken w/ K1: Pentax SMC 50 mm 1:1.2 w/ split +1 diopter filter, @ 1/80, f/8, ISO100, SOOC w/ mirroring)
