Auto Extension Tubes and IS lens?

[russellsnr]

Hi, Quick yes or no question. If you use auto extension tubes on a lens with IS does it retain the IS option. Thankyou, Russ

[Dave Humphries]

Probably yes, in as much as I'd expect it to, if ALL the electrical connections are there.

However, I have no direct, recent experience to confirm.

It might help if you told us which camera, lens and tubes you're using).

However, bear in mind it won't be as effective as you normally (i.e. w/o extension tubes) expect due to the increased magnification.

Cheers,
Dave

"IS" = Image Stabilization (i.e. 'Canon'), so assuming you are talking Canon AND the 'auto extension tubes' have the EIGHT PINS, the answer is:

YES

As per Dave's response I would expect a generic answer of "yes" for other gear, provided the tubes have ALL the pins.

And if it works, I wonder if you would be glad with it. I'm not sure but I think that the result of IS or VR is influenced by an extension between lens and sensor.

There are some that say IS/VR has little influence with close up/macro with or without tubes.

From my own experience I could not confirm that it has given sharper results whilst hand holding but it gives a great advantage in steadying the image in the viewfinder you see whilst manual focusing.

. . .the result of IS or VR is influenced by an extension between lens and sensor.

That's a logical assumption to my mind. Any movement reduction system located INSIDE the LENS would have compromised (worse) results as the lens was moved farther away from the sensor, but I think when evaluating the practical use of IS for MACRO or CLOSE UP work, the factor of the SUBJECT being so close is more of a problem for IS to deal with . . . that's what Graham's comment was getting at.

My experience in this area is limited to one lens, yet I actually use it (and a tube) quite often when traveling on holiday. The EF 24 to 105/4L IS USM is my usual travel companion and it is a reasonable "Close-Up" Lens, and with a short Tube it is quite handy: I rarely (almost never) carry a Tripod or Monopod on holidays - I concur with Graham, the IS is very useful for focusing manually for Close Up work: the final focus is by moving the Camera slowly in and out.
