Wide Angle Lens.
Wide angle lenses are usually defined as a lens that has a wider angle of view than the human eye. But you need to understand a couple of important things.
Firstly not everyone has the same angle of view with their unaided sight. Secondly, the angle of view is somewhat subjective. As we all have varying degrees of peripheral vision. My best lay-mans explanation of peripheral vision would be to describe it as visual awareness. You can see something but it isn’t very clear. Look at it as the visual early warning system that tells you something is there and you need to take a closer look.
So, a wide angle lens clearly sees a wider view than you do without turning your head or eyes. Then we have an extreme wide angle lens capable of taking in a very wide area of the scene.
Macro enthusiasts are unlikely to race out and buy this one, but it is there if you need absolute precision. Alpa, a highly respected manufacturer of handcrafted cameras and components with a reputation of going to extremes to produce some of the finest photographic tools made.
For example, macro shooters will be aware of using sliders to help focus in extreme close-up situations. Most will also be aware of focus stacking to create extended depth of field. And most of us would be very happy with being able to rack our camera back and forth a couple millimetres at a time.
Not the good people from Alpa, their new focus slide can be programmed to move a mere 1/5000 of a millimetre at a time. Plus a whole lot of other incredible stuff.

Google is introducing image creator information for online searches.
Great news for all photographers posting images online. Allowing people who view images after an online search to identify the copyright holder.
Admittedly they still have to click an icon to see the copyright information, and it will not stop the theft of photos. But it will eliminate the excuse that they couldn’t identify the creator.
Again it won’t stop people from stripping out information from image files. It will remove some of the dodgy practices around stripping metadata from photos. Hopefully, other large social media and search platforms might also follow the lead and help protect intellectual property.
As a side note, did you know that some social media site strip your ownership details from your images before displaying them?
