This extender works with my 800 mm lens and my 100-500 zoom. This is a must for nature, wildlife and bird and insect photography. I couldn't be happier.

Found lens pricey but works great with my my RF 100-500mm lens. All camera functions work with extender. When you can't get close enough this is a good addition.

Canon Extender RF 2x using with RF 100-400mm

By Gail

Very happy. I have the best of both worlds. It turned my RF 100-400mm into a 200-800mm; which gives me the ability to reach across the sports field or to photograph wildlife. I almost bought the 800 mm prime, but this combination is great. Glad To have it when I need to have a extra reach.

Sharp!

This extender is tack sharp when I can steady the camera or shoot from a tripod. Once I learn the tricks of focusing with an already long lens, I am sure that the photos I shoot will all be as sharp as those are when the camera is on the tripod. The lack of 5 stars for to the fact that with the RF100-500 lens, the range of zoom is only 300-500 and makes for an extremely long lens to carry. I have heard this from friends that have this combo and we all agree on this drawback.

Sometimes have problems with the Canon RF 2x Extender

By William

I can make the RF 2x extender work with my RF 100-500 lens, but it sometimes has problems focusing on nearby birds. I have to hold the central focus point on the bird while the lens keeps trying to focus on the nearby bird. Eventually it will focus properly but I have missed getting some good photos. With distant flying birds. the RF 2x extender will often require that I focus on some trees first at about the same distance away as the distant birds so that the camera will find the birds and focus on them. I have used it with the 100-500mm lens to get nice 1,000mm photos of distant birds.

Great addition to my RF Kit

I was a little unsure about getting a 2x Extender. I have had one years ago that I did not like. After getting the RF 1.4x I was surprised how well the images turned out I decided to try the RF 2.x. I am glad I did, the results are great with my RF 100-500. I am very happy with the extra reach. I do wish Canon has designed the 100-500 to be a big longer to allow full zoom range with a TC, but still I love the TC combos.

Fantastic Doubler

By Pierre
Rated 5 out of 5
Date: 2022-05-29

I have the Canon RF 100-400 mm L lens as well as a 1.4X Canon extender. I was concerned with the image quality I would obtain with a 2X extender, but after seeing multiple images from colleagues, I decided to buy one. WOW!!! This doubler provides very sharp images while preserving a very quick autofocus. I am very happy with this purchase and would recommend it to a friend. The only caveat with this lens is the limitation of the zoom range from 300 to 500 on the lens due to the protrusion of the extender in the lens (true for the 1.4X and the 2X extenders).

Can you safely use a 2x teleconverter with extension tubes(all Canon original)? Just curious!
Asked by: Yo
Extension tubes will fit the 2x converter but how well they work would be unknown. The tube)s) would need to be mounted to the camera, then the 2x converter, and then the compatible lens. Automatic functions such as AF and auto exposure might be lost too.

If used with 600m lens it stops to f22, does that effect the camera settings e.g. shutter speed and ISO?
Asked by: Carlie
Yes and no. To maintain a correct exposure, your exposure settings will have to compensate for the loss of light. With the 2.0x teleconverter, you lose 2-stops of light. For the "no" answer: in manual, since you have to change these settings yourself, if you do not change your shutter speed or ISO to compensate, your picture will come out 2-stops darker. So if you decide not to change them, technically the lens and teleconverter do not have any control over your other settings. For the "yes" answer: in P/Tv/Av, your shutter speed and ISO will adjust accordingly to your EV compensation, min. shutter speed settings, and also Auto ISO ceiling (if applicable).

If used with 100-500mm RF, is it possible to damage the lens if it is tried to go below 300mm by mistake? The hit is directly on the lens or does it has a safe stop?
Asked by: Damian
The RF extender prevents the lens from retracting past 300mm. From my tests here at the Superstore, while it is might be possible to damage them if you really tried, it seems unlikely as the force generated by rotating the lens between 500-300 isn't very high.
