Canon EF 5,6 100-300mm L


For a long time I was looking for an affordable zoom with a focal length of 100-300 (400)mm. And just as long I forgot about the lenses from the early days of EF lenses, even though I did my first training in the photo trade as a young man back then and therefore knew these lenses well.
For my last Norway vacation, I got the Minolta AF 4.5-5.6 100-300mm APO and adapted it to my Sony A7III - but I was not happy with this lens because of its modest imaging performance.

Then I saw it: an "L" lens for under 200 euros? Plus a 100-300mm telephoto zoom?
I thought about it only briefly and bought the lens at auction.
Canon writes on its homepage (Canon camera and lens hall) about this lens:
"Powerful lens with 3x telephoto zoom. Synthetic fluorite in group 1 and UD glass in group 2 provide low refraction and low dispersion. They also effectively correct chromatic and other aberrations. Resolution is high across all focal lengths. Images are sharp and crisp. At a focal length of 300 mm, 0.25x magnification is possible."

Meanwhile, further down you'll find two video about this lens. In the first video, I tested its image quality on the Sony A7III, a 24 megapixel mirrorless camera. Furthermore, you'll learn all about its mechanical quality and autofocus performance. During my vacation in Varanger National Park in Norway, I tested this good piece extensively on the Canon EOS 5DsR - Canon's 50 megapixel SLR behemoth. Enjoy watching and I think you will learn some interesting things about this lens.

At full aperture, the corners of the image lose just a little bit of performance
