Probably not. The Canon extenders have a protruding front element that may interfere with the rear element of the lens. Apart from that an 18-270 lens is not a good starting point for an extender. You’ll loose a lot of quality, probably autofocus as well.
In the same way Can I use a Canon Extender on a Sigma lens?
The tape will not ever come loose no matter how many times you attach and de-attach the lens, so don’t worry. This particular contact is for Sigma cameras only, so if you are using a Canon or (probably) any other brand) this will work as well. This will make your Canon tele-extender work with the Sigma lenses.
Subsequently, Can you use a Sigma teleconverter with a Tamron lens? The Sigma 1.4 teleconverter is a non-reporting converter so the camera will treat the combination as if only Tamron 150-600mm is used.
What lenses does the Canon 2x Extender work with?
It works with 70-200s and the 100-400, 135/2 and 180/3.5 macro, and otherwise is optimized for Canon’s big white supertelephoto lenses. It wont work well or at all with f/5.6 zooms or normal 50mm, 85mm or 100mm lenses.
Will a teleconverter work with Sigma lens?
Lens Compatibility
Nikon teleconverters are designed to only work well with Nikkor lenses, while Sigma teleconverters are designed to only work well with Sigma lenses. So if you were thinking of buying a Sigma 1.4x teleconverter to be used for a Nikon telephoto or super-telephoto lens – forget about it.
What cameras are Sigma lenses compatible with?
The Sigma DC lenses are specifically designed for APS-C SLRs such as the Canon Rebel Series XT, XSI, T5, T6, T1i, T2i, T3i, T4i, T5i, T6i and the EOS 7D, 7D Mark II, 40D, 50D, 60D, 70D, 80D and others. The Sigma DG lenses are designed to be used with either full format sensor SLRs or APS-C SLRs.
Can I use Nikon teleconverter with Sigma lens?
It turns out that teleconverters are very brand-specific. Nikon teleconverters are designed to only work well with Nikkor lenses, while Sigma teleconverters are designed to only work well with Sigma lenses.
What is a tele conversion lens?
A teleconverter allows you to increase the apparent focal length of a lens, giving you a greater telephoto effect than a lens alone. A teleconverter is basically a magnifying lens that is placed between the camera body and lens. … Nikon currently offers teleconverters in 1.4x, 1.7x and 2x magnifications.
Are lens extenders worth it?
While teleconverters give you decent image quality, they still cause the photos to lose some of it. However, they are still much better than cropping the image, and they preserve way more quality than cropping. This probably goes without saying, bit when you’re using a longer lens, there’s more camera shake.
Which Canon Extender is the best?
1. Canon Extender EF 1.4x III (Overall Winner) The Canon Extender EF 1.4x III is a commonly used unit for the Canon EF mount, extending the focal length by a 1.4x factor.

What is the difference between Canon Extender II and III?
Results with the Extender 2x III are overall slightly sharper than the Extender 2x II with a difference being most noticeable in the mid-frame and corner areas. The 2x II added pincushion distortion to the lens it was used with whereas the 2x version III adds slight barrel distortion.
Are Tele Converters any good?
While teleconverters give you decent image quality, they still cause the photos to lose some of it. However, they are still much better than cropping the image, and they preserve way more quality than cropping. This probably goes without saying, bit when you’re using a longer lens, there’s more camera shake.
How are teleconverters calculated?
The easiest way to figure how much a teleconverter (TC) increases the f-number without doing any complex math is to do this: Take the linear magnifying power of the teleconverter and compare it to how many stops away from “1” it is on the f-number scale. ¹ That’s how many stops you lose.
What is an APO teleconverter?
The Sigma APO Teleconverter 1.4x EX DG for Nikon Digital SLR Cameras is a dedicated APO teleconverter that can be mounted between select lenses and the camera body to increase the focal length by the power of 1.4. The multi-layer coating reduces flare and ghosting, which is a common problem with digital cameras.
What is a DC lens?
“DC” stands for Defocus Control. DC allows the photographer to change the distortion characteristics of the lens so the “look” of the out-of-focus elements in the foreground or background can be changed to produce more pleasing photos, particularly portraits.
Are Sigma DC lenses full frame?
While the Sigma 18-35mm f/1.8 DC HSM Art Lens is designed to cover only an APS-C-sized camera sensor, this lens mounts and functions on a full frame DSLR.
What does APO mean on a Sigma lens?
A: Sigma’s APO designation means it’s a apochromatic lens that uses low dispersion glass to minimize chromatic aberration. The DG designation signifies that it is a Full Frame lens.
Which Nikon teleconverter is best?
Which Nikon teleconverter is the best? Based on heavy field use of all three Nikon teleconverters, the TC-14E III is currently our top recommended teleconverter. It has very little impact on image quality, and it works well with most Nikon telephoto and super-telephoto lenses.
Can a Nikon 200 500 use a teleconverter?
The Nikon 200-500mm f/5.6E VR does not have such issues, because of its brighter maximum aperture of f/5.6 at all focal lengths, which is why the lens is actually suitable to use with the 1.4x teleconverter.
What does a 1.4 extender do?
Use of a 1.4x extender (any brand or model of them) decreases/narrows your lens’ max aperture setting by 1 stop – allowing at most 1/2 as much light into the exposure. The lens aperture still opens to the same physical diameter, but the ratio of the aperture opening to the focal length is reduced – by 1 stop.
What is the disadvantage of extension tubes?
The only disadvantage of extension tubes is that there is some light loss. Adding an extension tube increases the effective aperture of the camera lens, which means you need to use either a longer shutter speed or higher ISO to compensate for the loss of light.
Do teleconverters really work?
Without exception, teleconverters always make lenses less sharp. While more expensive wildlife/sports lenses can do a decent job of controlling a teleconverter, it still means losing some image quality. … Unfortunately, teleconverters reduce the aperture size. A 1.4x teleconverter makes a lens lose 1 stop of light.
How many f stops do you lose with a 2x teleconverter?
A 2x teleconverter loses 2 stops of light, so an f/2.8 lens drops down to a wide aperture of f/5.6.
Is using a teleconverter better than cropping?
Your images will have lower contrast
Finally, using a teleconverter will tend to lower the contrast in your images when compared to images taken without one. However, it goes deeper than just the final image. This reduced contrast can also affect your autofocus since your camera uses areas of contrast to achieve focus.
What do camera lens extenders do?
Lens extenders (also known as teleconverters) increase the effective focal length of your lenses. … Extenders, generally known as teleconverters, increase the effective focal length of lenses. Canon Extenders are available in two strengths, 1.4x and 2x.
