Excerpt: The K-7 was my first DSLR after progressing from a Ricoh XR-P film camera via a terrible little digital P&S. My initial feelings were mixed. I loved the look and feel of the K-7 and felt immediately at home with the controls and layout. I also had a few Ricoh K-mount lenses which helped a little in the adjustment process. Fortunately I had no issues with the feared "Ricoh Pin" which I only learned about afterwards.
Pros: Handling, weight, solid feel and construction, WR
Summary: I have owned this camera since Feburary of 2011. The features have been written about extensively so I will write about how it is to use it. I have pounded this camera in the dirt, dust, wind, rain, and snow. I have had it photographing offroad races, wilderness in all seasons. It has just never failed. The dust and water sealing works impeccably on the body and lenses. I have shot down to zero degrees without an issue.
Summary: In the short time that i have had it ,its been a great upgrade from the FS-1 that i had , also all my lenses fit. The learning curve is a bit steep if you want to understand all the capabilities of this fine camera.
Summary: This camera is a beast. Working in the construction industry I was looking for a camera that would last in demanding conditions, Pentax seems like a good choice, I had the waterproof point in shoot that was a few years old it is was a workhorse but it was time to upgrade to something better. About a year after purchasing the camera while out on the jobsite I dropped the camera on the dirt it bounced down into a trench that was 10 feet deep.
Summary: I have shot over 10,000 photos with my K-7 in all sorts of environments, been caught in pouring rain, had various liquids spilled on it (including martinis) and it still works as well as when I got it. Durable,great features, better and cheaper than anything Nikon of Canon has for anywhere near the money. This is a truly wonderful camera for either the hobbyist or professional - and it takes a lot more abuse than any other DSLR camera I know of .
Summary: I've been using the K-7 for 9 months now. Over and over again, I think, wow, this is a camera that was designed for photographers by photographers--button placement, menus, custom functions---everything is thoughtfully put together, unlike some other cameras you feel are just cranked out. The K-7 is a hidden gem.
