Well..if I have to consider a B&W, Pentax beats both Canon (that is too smooth) and Nikon (that lacks the contrast). I am the only Pentax user between my friends photographers and they are always amazed with my B&W images (not only though).. I love portraits, and Canon images are quite attractive, I shoot a lot outdoors, general family images, and Nikon would be great with it's perfect exposure and white balance, I love the Sony colors (I have consumed dsc-v1 to it's end), Olympus is fun too (I was considering it too).. But after all the hard studies on Steve's digicams (I've got my 1st SLR - Pentax K10D with 2 kit lenses in late 2007).
I keep myself tied to Pentax because of its versatility..it is like a tank, goes everywhere and delivers excellent results. So I am not switching to any other brand. Only regret is that I didn't by enough K mount lenses a few years ago..it seems that prices are going to the stars lately..at the moment I have 2 kit lenses plus these: smc pentax af zoom 35-70mm f2,8 (a huge and rare lens, very sharp I love it),
tamron adaptall 80-210mm f3,8-4, that became my general 'walk-around' lens, equally excellent for scenery and portraits, also macro),
smc pentax-m 28mm f2,8, a small, lightweight, sharp and snappy focus lens, I love it too..
and auto makinon macro 135mm f2,8, an amazing portrait lens sharp or silky, depends on how you choose to use it..amazing in every light condition..
At the moment I am using Pentax20D (since 2009), because my K10D crashed (the body broke in one of the bottom corners) against the stone floor, popping out of terribly arranged camera bag, what a pain! This was the period when I was considering switching to another brand (Nikon D300), but I didn't.. because the only issue that I have always had with Pentax cameras is unprecise white balance and often green/magenta cast on images that I can fix always since I shoot only DNG. This issue has been considerably inproved in K20D. And one more thing to do is to lower contrast setting in camera. This makes almost no issues anymore. I'd love to have K5, but I dont trust its HD video thing..
PS. I couldn't survive without Pentax in camera laboratory that is so much of fun!
