The cellphone’s impact on cameras

July 18, 2011 JimK Leave a Comment

In the last post, I talked about the cellphone’s impact on photographic art. In this one, I’ll return to safer ground, and tell you what I think will happen to cameras in the near future. Cameras will become ubiquitous in cellphones. Because thinness is a selling point for cellphones, lens focal length and therefore sensor… [Read More]

I decided to complete my testing of Sony and Leica lenses on the Sony NEX-5 by comparing some Leica lenses to the Sony 18-55 mm zoom. I used three Leica lenses for the comparison: The 16-18-21 mm Tri-Elmar, set at 18 mm to match the shortest setting of the Sony zoom The 24 mm f/2.8… [Read More]
