Kenko Extension tubes

[wildlight]

Hi,

I'm interested in getting some extension tubes for my Sigma 180mm lens.

Has anyone used the Kenko extension tubes and are they any good compared to the Canon version?

 

Cheers,

Joe

I have not used it but I have read about it.

Since they don't have any glass, so IQ does not change from one to other.

And one thing to note is Kenkos is not compatible with EF-S lenses.

Thanks for the info.

I'll be using them with a Sigma 180mm so the non-compatability with EF-S lenses won't matter.

 

Cheers,

Joe

I purchased a set not too long ago. I have had no problems with them on my 70-200 F4 L and the 17-40 F4 L. Autofocus and exposure are unaffected. Extension tubes don't have any glass so image quality is determined by the lens and sensor.

Kenko has two lines of tubes. The "DG" series works with both EF and EF-S lenses, while the non-DG only works with EF lenses. Canon's own tubes don't work with many of their lenses, so the Kenko tubes are pretty much the best option for Canon shooters who want to retain electronic control.

 

Since I can't afford $170 for a nice set of tubes and since I shoot with a number of manual lenses on my 400D, I found a set of tubes with no terminals for just $9 on eBay. It works for the time being.

Okay thanks very much for the information!

I'll definately be getting a set now :-)
