I have a Canon EF 400mm f/5.6L USM Super Telephoto Lens and a Canon 5D Mark ll camera. Will these let me focus at a closer distance?

Yes it will... I have the basic 300mm which focuses at a little over 5 feet.. with this attachment I can focus at a little over 3 feet...

This is strictly for macro. Focusing on anything that isn't at the closest focal point is impossible. It is also recommended that you use a lens with a shorter zoom level. This is basically incompatible with my 250mm. I can only imagine how much worse it is with a 400mm.

No this is to increase the zoom for macro photography. It does not work with a telephoto lens, the camera will not be able to focus. You would need to look into getting a telephoto extender

Hi, I ccqn't answer the question sinceI'm using the lens with my Canon 5d mark III.

I have a T3 Canon and the unit does focus my camera. It takes two AAA and one 12 volt/23A that come with it. I bought mine for family and work group photos.Steve Durbin

I also use this with my 5DII. I just tested it and the camera will refocus before the shot. If you don't want that, you can just turn off auto-focus on the lens.

I own the 100-400, 4.5-5.6 L lens. Autofocus does't work on the 7d, but if you use it on live view or mirror lock-up it does auto focus. Good luck!

Yes, doesn't matter what lens you have. This follow focus really good for the price, very solid, no loose parts, at least i received a fine one.

I have the Canon 100-400 lens and I borrowed my friends 400mm lens for a week. The 400mm lens is a little sharper than my 100-400 lens and seems to focus faster. I still like my 100-400 lens because of the versatility. The 400mm lens take a minimum of 12 feet to focus and the 100-400 will focus at around 6 feet. The 400mm lens is sealed but the 100-400 lens because of the push/pull zoom will over time allows some small dust particles to enter lens. If all you are going to use it for is wildlife, then you can not go wrong with the 400mm prime.

I bought it for a 400mm 5.6 & manual focus only...which is just as fast or faster than auto many times... I wanted the distance

I use a 7D and will be upgrading to a 6D. I can tell you it does not work with my 7D and a Canon 100 -400mm L series lens. I have to rely on manual focus which is a real bummer! I really don't want to pay Canon's price for their 2x teleconvertor, but may have no choice. Hope this helps

I think yes. I'm not positive because I haven't measured subject distances, but have gotten sharp focus at 3-5 cm.

Yup. Autofocus works with my nex-6. With the extension, the focus range is only a few inches deep. As long as your subject is in that range autofocus would work fine.

I don't know but I don't think that you can do anything but manually focus with these lens babies... they are not designed to autofocus so there is a bit of a learning and experimenting with them till you get the look that you want....each aperture ring gives you a slightly different look... so you have to know where to direct your focus.. and that has to be done manually....

The lens (for a Canon EF mount) will mount but the sensors and the electronics won't work, so you'll need to focus by hand.

technically yes. This is a fixed focal length lens. since the 6D is an SLR, I would suggest to go with movable focus lenses. There are millions of 18-55mm or 200-500mm telephoto lens, at affordable prices.

Closest usable focus distance is about 5.5 inches from the lens. What that means in practice is that an item one-half of an inch across will fill about half the frame (at least on my 50D).

This lens is for close up pictures at relatively short distances. The other is a telephoto lens for taking close ups of larger items at longer distances.
