Spot AF first appeared on the Canon EOS 7D camera and has since been included on several other models, including the EOS 5D Mark III and EOS-1D X. However, there is still some confusion about how it works and when to use it, that we’ll clear up after the jump…
As a photographer, one of the most exciting but nerve wracking things you can do is get on a plane with camera kit. Before you go, you have the mental anguish of what to take and what to leave behind and then you need to figure out how to get all your photo kit into a bag so that it goes onto the plane easily.
Welcome to April! Seriously, what happened to January, February and March? Anyway.
We had an email in the other day asking about autofocus setup on the EOS 5D Mark III and EOS-1D X, from a very well known wildlife photographer. They’d been struggling with picking the right settings in the case studies and weren’t quite sure which AF point selection method they should be using on their cameras and for their types of photography.
The pace of lens production has increased significantly in recent years with new lens production milestones now coming at around 9 month intervals. It took 8 years to hit the first 10 million lenses so it has taken some significant changes in the market and the production capabilities to hit the current estimated 12 million lenses per year.
Canon EF lens production
If you assume that the most popular lens Canon currently makes is the 70mm long EF-S 18-55mm f/3.5-5.6 IS II, then if you assembled 80 million of these lenses – some of the actual eighty million are far longer in length – you would have a line of lenses that is 5.6 million metres (5,600 km) about one-seventh of the circumference of the earth.
Plenty of space for more lenses then!
Canon today has thrown us a bit of a curve ball. For the first time since the launch of the EOS system in 1987, they have launched a new lens mount. Don’t fear though, this doesn’t signal the end of the EF mount. Rather it heralds the beginning of a new line of camera for Canon, something other manufacturers have been doing for a while, but which Canon has been taking it’s time over – a Compact System Camera or CSC. This is basically a DSLR without the viewfinder, shrunk to fit the size of a compact camera, while still keeping interchangeable lenses. Read more
