Concerns over the Leica Q2
Here are the things I’m concerned about before I can say I will invest in the Leica Q2: Back Button Focus – read my concern over this in my post “Have Leica broken Back Button Focussing on the Q2?” – I’m hoping this will be rectified in a firmware release. Position of the EC Dial… Read More Concerns over the Leica Q2
Have Leica broken Back Button Focussing on the Q2?
In his write up of the Leica Q2, Jonathan Slack describes how the small “zoom/lock” button on the back of the camera (near to the thumb indent) can be assigned the following functions: Digital Zoom, AEL / AFL, AEL or AFL. He then goes on to describe how when the the AFL function is chosen,… Read More Have Leica broken Back Button Focussing on the Q2?

Leica Q2 Crop Options
The Leica Q2 is a 47 megapixel full frame camera, which by default produces a 3:2 aspect ratio image of size 8368 x 5584 pixels from its 28mm lens. It also offers the option to crop to 35mm, 50mm and 75mm equivalents – this is by overlaying crop guide lines in the EVF and back… Read More Leica Q2 Crop Options
An approximate lens formula: i/f = o/d
Use this formula to get an idea of what lenses will work in what space, what area of subject a lens will cover at closest focusing distance.… Read More An approximate lens formula: i/f = o/d
Light and the Inverse Square Law
At some point in your photographic life you will inevitably come across something called the Inverse Square Law (ISL), which relates to light fall off with distance and how that affects exposure. A lot of photographers are put off by this mathematical construct, and while the physics behind it is relatively complex, its quite easy to understand and apply.… Read More Light and the Inverse Square Law
