Excellent and Reasonably Priced Deep Sky Astrophotography Alternative

Was looking for something more versatile than a dedicated astrophotography lens/telescope, but no one makes a similar lens as this Cannon with an E mount for Sony and anything close was exceedingly expensive. Found this lens and using a Metabones adapter, the lens works very well with my full frame Sony camera. Images are sharp and the lens is faster than dedicated telescope lenses.

Not a deal breaker by any means, but wish it had an external aperture ring. This lens can be used in fully automatic (aperture and focus) or manual mode. Manual aperture is done using the camera controls and focus with the focus ring. Image stabilization is impressive. Other than the price of filters because the face of the lens is quite large, I have found no real negatives, considering it is not being used natively on a Cannon camera.Read full review

Great lens for a great price?

This lens is sharp and very colorful. It can freeze your subject and make it stand out from its background. It also has a nice background blur. And don't forget, it is image stabilized so you can handhold it a slow than the prescribed 1:1 zoom:to:shutter speed ratio. That is a BIG plus! If you can get a good deal on one, it becomes a no-brainer. -CwhRead full review

Unbeatable quality and value

Wonderful lens! Even though it lacks IS, it is very usable given the quality results with newer cameras which handle higher ISOs very well. Construction is first rate and handling is a real pleasure. Very usable with the Canon 1.4x teleconverter. Image quality? It's an "L" lens! These lenses very much deserve their stellar reputation. UnbeatableRead full review

Canon EF 300 mm F4 L IS lens is GREAT!

This lens is great for the price and build quality. The auto focus of this lens on my EOS 7D mark 2 is a BIG WOW! I've had other long lenses by third party manufacturers that were slower in the focusing department and this lens blows them away. The image stabilisation is second to none when hand held shots at 1/60th of a second come out like it was on a tripod. This is my fourth "L" lens and they are worth the extra bucks.Read full review

Sharp pictures, but clunky loud focusing

I have shot some great pics with this lens. Nice and sharp, and shot some great portraits with it as well as wildlife with a 1.4 tele.
On the downside the focusing motor is loud and clunky sometimes seems to jar the image as it jumps in the viewfinder. It searches more than my 70-200 L, and not nearly as smooth or fast. I find myself manually focusing initially.Read full review

Awesome lens by Canon

This is a great lens and the 300mm f4 is my second prime lens from Canon. I'm very impressed with the bokeh and sharpness of this lens. I have used this prime lens to take some great images.

Outstanding lens

This lens is really sharp. I am using on a Canon EOS M6 camera, so it becomes 480mm lens. Fitted on the M6 with the Canon EF to M adapter...no problems. Highly recommended Len. Read Ken Rockwell’s review.Read full review

Good lens for the price

As a much cheaper alternative for the huge 300/2.8, this is a great lens. Cheaper and lighter than the 70-200/2.8, this lens gives you an excellent combination of the reach of 300mm, relatively large aperture at f/4, and great portability. Image quality is great, auto focus is fast, and the built-in lens hood is really convenient. The only downside is that if you are shooting videos, the noise from auto focus and image stabilization system can be a problem. After all, this lens is designed almost two decades ago, and I really hope Canon would come up with an update.Read full review

Excellent for Eclipse Photo

Since I was tripod mounted for the eclipse, IS was not so necessary. In fact, with such a long lens, I would tend to be tripod mounted for most future uses. The lens is true Canon. What else can you say about durability and quality?Read full review
