Related Questions and Answers

Q: 1. Does the 300mm f/4.0 IS USM lens work with an extender 1.4x II on a 60D camera body?

A: Yes, the 300 mm f4 IS lens will function very well with a 1.4 X extender. It will slow the auto-focus down, but it will still auto-focus. That combinations worked very well for me while shooting wildlife, with the extra bonus of being very close to being a macro lens. The extender doesn't change the close focusing ability of the lens, so you have a 420 mm lens that focuses down to just under 5 feet.

Q: 2. Can you auto focus with the 2.0xiii extender ?

A: Yes and no - just tried it a few weeks ago. It worked, but extremely slowly and sometimes didn't focus on what I'd want, so I find manual focusing with the 2x is easier. By itself though, the 300 4.0L is fast at focusing.

Q: 3. How much does the detachable tripod collar weigh?

A: 4.1 oz or 117 gram

Q: 4. Do you have to use manual focus with this lens and either the 1.4 or 2.0 extenders?

A: The 1.4 will auto focus on the 7D and 7D mark 2 and it takes beautiful photos. The 2.0 will not auto focus on the 7D I think it does on the 7D mark 2

Q: 5. Is the tripod mount supplied with the lens

A: Yes, the tripod mount ring is included with the Canon EF 300mm f/4L lens.

Q: 6. What is the difference in image quality and functional automatic focus between the Extender 1.4x II and 1.4x III?(This is with a 300 mm f/4 IS L series lens on a 60D body.)

A: I have a 50D Canon Camera and the 1.4 III Extender. When used with the 300 mm lens I have no problem with the auto focus and there is minor image quality deterioration. You lose one stop on your aperture. It really is a great combination.

Q: 7. Anyone use this with the Canon EF 300mm f/4L IS USM Lens and if so with what success? I primarily use manual focus so dont care about auto focus.

A: I use this lens extensively, mostly for birding and wildlife. It's an amazing lens when working close, it focuses down to about 5 feet for near macro photos, especially with a 1.4 X or 2 X tele-converter behind it. I've also used it for a few landscape images, and it works very well then as well. I'd say that it is an excellent lens, but there seems to be a soft spot in it from about 20 feet to 50 feet, where the images it produces aren't as sharp as I get with my other lenses, but that seems to depend on the subject and other conditions. It is my primary bird in flight lens and on my 7D Mk II most of the time. It is a bit tricky to manually focus it, small movements of the focusing ring make large differences, but once you get the hang of it, it does work well. Hope this helps.

Q: 8. ...and while displaying my novice; can I inquire if this specific lens is compatible with the t4i?

A: Yes. This lens will work on the T4i. It will look like the equivalent of 450mm, due to the APS-C crop sensor, which carries a 1.5x conversion factor. All EF and EF-S lenses will work on this type of sensor.

Q: 9. Is this lens weather sealed?

A: The lens is not fully weather sealed as does not have the rubber gaskets. But since the lens is a prime lens it does not move in in out like most zooms so there is less chance of getting dust or moisture in it

Q: 10. I am interested in getting this lens for use on a Sony A7-II, as there is no E-mount equivalent. Does anyone have experience using this with a Metabones or Sigma MC-11 adapter? Does autofocus work with either of those on a Sony?

A: When using a 3rd party lens adapter and used to mate the lens and camera from two different companies, the issue always is the speed of the AF performance. As of now, even the very best is behind OEM performance. That being said, the best Metabones adapter with this lens should prove very satisfactory. While Sigma will not support the use of the MC-11 with other manufacturer lenses, many users have reported success with the MC-11 with non-Sigma lenses while an equal number have reported failure. Generally, the latest model lenses seem to work. We could find no reports of the MC-11 and this older design lens unfortunately.
