has anyone used this extension tube with the 70-300 zoom lens?

Yes, I have and it works great but only in bright light situations. It essentially doubles all aspects of the attached lens. But using this device in low light situations reduces light through the lens and the auto focus may not work properly in low light situations. I photographed a house across the canyon which was about 1/3 mile away and it looked close and the picture was bright and clear.

This collar is for the 70 300 L lens, I think it won't work with your lens.

probably not the 70-300 lens. an option is to set the pod support so the lens is partially with something- a limb a rock

Just mount the extension tube on camera body then fit your standard zoom lens, and you are good to shot. This is a cheaper alternative to try taking macro shots. After buying a real macro lens I stopped using these extension tubes.

I haven't tried it on a 70-300, but I have used it on a Nikon 55-200 af-s lens and the pictures always come out great. The only problem, as others have mentioned is that the autofocus often gets jumpy, and in some circumstances it won't autofocus at all. If you are prepared to use manual focus you'll have no problem.

It's designed for a 4/3 camera but if they make one for Nikon, I sure would recommend it. You can get much more expensive extension tubes but I don't see how it would help since all it does is move the lens further from the camera.

Here is what I understand. 500D is close-up which I attached to 24-70mm 2.8L and no loss. I have been using this 500D for close-up without any problem and I love it. I do not own extension tube but thinking about it so I read about extension tube. It seems to me extension tube will extend the focal length of the length it attached to. If 2X extension tube attached to 70-200mm, 70-200mm lens becomes 140mm-400mm so not need to buy 100-400 but your lens will loose 2 stops from its original. Hope it helps.Minh,

You need to check with Canon. The extenders work with some lenses and not others. I'm not familiar with the 2ti body or the 70-300mm lens in question. Also the lens speed will be effected and immobilize the auto focus. You may need to manual focus only. It may also effect the picture quality. I have the 1.4 and 2x. Like the 1.4 much more.

D. Schultz has the right answer. The EF 70-300 will not accept this extender. Even if it did, the 2X extender adds two stops to the lens. In order to keep auto-focus a f/5.6 or faster lens combination is required on a Rebel camera. This extender is mostly for use on a f/2.8 or faster lens.

I cannot answer specifically about the 70-300, but: I compared the dimensions of the case (what they said it could hold) to the dimensions of the lenses I use it for and got the right answer. (I use it for the Nikon 18-200 and Tokina 11-17. Both fit snugly with hoods reversed, as predicted.)

Concur with Rich Maher's comments. However when I use it with my Tamron 18-270 zoom I find that I need to use manual focus as it gets a little "confused" with the extender.

It was designed for the 70-200 G lens; however, I have read of some using it with the 70-400 G. I do not know about with the 70-300G. Do note the minimum aperture on the 70-300 lens would jump from 5.6 to 11. That is a lot of light loss so you would have to have a very low shutter speed, thus needing to shot from a tripod likely or objects not in motion.

I use it with a 7d and 70-200l lens it works ok with one other lens. I like the retro look and loots of pockets. I have tamrac expedition 7 for lots of lenses in the field.

Yes, it comes with an extension tube that effectively doubles range to 1000mm. Bear in mind, this is a MANUAL lens. You need to focus by hand and use a tripod.

That would be a poor choice to use with extension tubes. Its minimum focus distamce is 1.8m (6 feet). You'd need to lower its filter size to 72mm in order to acquire and attach a 72mm macrolite adaptor (not included). You'br better off using something normal to wide with extension tubes, or even better some of the macro lens options straight with the flash (macrolite adaptors are required for all but the mpe65).

Yes it will work, its about the mount rather than anything, this extention tubes doesnt have any lens elements so as long as it is F mount lens and camera will fit but just be careful, the one i got it little tight for lenses but it works fine. If the weight of the lens is too much it might bend the tube since its plastic.

It attaches to the front of the existing lens, so you might have a small vignette in the corners to zoom past if you use up to a 300 as I use.
