Canon 300mm Lens Shootout

On this last part of the mini-series of the big Canon lens comparison, Pye from slrlounge takes a look at four 300mm full frame zoom and prime lenses from Canon . This isn’t a laboratory test but more of a real world test to look at different aspects of these lenses and how they will affect your actual photography.

The 4 lenses being tested here are:

  • Canon EF 300mm f/2.8L IS USM II – The king of this this test with a bank breaking price of $7300 (Amazon).
  • Canon EF 300mm f/4L IS USM – the most cost effective high-quality option priced at under $1500 (amazon).
  • Canon 28-300mm f/3.5-5.6L – very flexible zoom but hugely overprice at almost $2700 (Amazon).
  • Canon 100-400mm f/4.5-5.6L – the longest zoom-telephoto price at just under $1700 (Amazon).

So in terms of overall quality, the winner is the Canon EF 300mm f/2.8L IS USM II (no surprise here – and there shouldn’t be for a lens which cost over $7K), but the Canon EF 300mm f/4L IS USM was not that much far behind and for almost $5K less it should be the price/performance king. As for the other two – the Canon 100-400mm f/4.5-5.6L is actually a 400mm lens so it should be in a whole new category and the Canon 28-300mm f/3.5-5.6L has a huge range but it price is just completely unjustified.
