I am using Nikon F and Nikon F2 since more than 35 years ago. They are really very good cameras. As it is now a digital world, but in other hand I like to keep using my SLR film cameras, at first I bought Sigma DP1 as my sub camera. It gives really very clear and beautiful pictures. However it is a very slow life camera. Nikon gives also very good pictures in outdoor situation. But in indoor situation, its fixed daylight WB and ISO sensitivity, once a film loaded, give me some frustration, especially I see digital SLRC user taking photo. So now I bought Pentax K-7.
Its compact design compared to other manufacturer's SLRC with APS-C image sensor, 100% aperture of its finder, Shake reduction and Sensor cleaning mechanisms, Weather resistance (WR), they are the points why I choosed Pentax K-7.
So now I am using all of these 3 cameras. If I got new Pentax, I will give it to my daughter. Hoping to take photos with her, side by side.
