An actual Canon 300mm F/1.8 lens exists, but you will probably never get to see one

If you thought a 300mm telephoto lens with an aperture as big as f/1.8 has not been made, think again. Canon has actually made this giant. As you can see it is a massive lens that's clearly not going to fit in your backpack as the glass element on the front is just huge.

According to Emil Wiik Larsen of @canongearnerd, “The lens is used for photo finishes in horse races. It has an EF mount and weighs a ton.”

The one that you see in the pictures was used by photographer Jim Anderson which he used to shoot horse races. He says that only has information of 4 of these lenses in existence and there is hardly any information about the lens online. This makes it an ultra rare lens, even more than Canon's 1200mm f/5.6L which has just a dozen units and plenty of information around the web.

Anderson says that this lens is used for strip, or slit photography. "With this system we can record up to 10,000 ‘strips’ or lines per second. That is how I came to work with this lens. I started doing photo finishes in 1986. Back then it was done with filmstrip or timing negative film. I would develop immediately after the race it would take about 8 seconds using dektol at 140 degrees and dip and dunk by hand. When digital took over film things became so much more advanced and so did the lenses. I have used this lens now for a little more than 6 years.”

Just imagine the possibilities if this beast is mounted on a standard full-frame camera!
