2 x canon converter
Feb 18, 2014 11:13:42 #
A friend lent me a canon 2x converter for my canon 100-400 L , zoom lens, for my trip to Costa Rica. All he said was " no more auto focus and I lose one or two f stops"
Can anyone elaborate on advantages and disadvantages of using this device.

There aren't many advantages - but it will make your 100-400 a 200-800 but your images will be a little soft. The disadvantages are that it will absolutely not autofocus, soft images at 400mm, and your f/stop at 400mm will be f/11. At f/11 you will have shutter speeds that are slower than you like to stop action or you will have high ISO with more noise in your images.

Do yourself a favor and leave the 2X home.
The problems will outweigh the benefits trying to use it with that lens.

The Canon EF2X III will allow your 100-400L to auto focus; albiet, much slower and probably not as accurate.
I tried one of these at the Reno Air Races last year, and as others have said, it's not ideal. I captured better photos without the extender and by cropping in. Your max aperture will be f/9.5 - f/11, so make sure there is a lot of light.
Personally, I think the disadvantages outweigh the advantages. The 1.4 extender would be a more difficult decision, but still not worth the money.

from the other side, with a good lens and a good teleconverter the results can be good to great. I have a sony Minolta 200mm G lens and their 1.4 and 2.0 converters. with either auto focus is fast and accurate.the biggest apature is 5.6. they also make a 300mm f2.8 and the results are about the same. under "search" you will find samples.
one more note, I was watchinga " adventures in photography", on pbs the guy had a humongus white lens on his camera + a teleconverter. nuff said???

No, which lens and which TC? If I had a $20,000.00 budget I am sure I could put together a good combination also. unfortunately that is not going to happen.

I just guessing, but it looked like a canon, and they do make their own converter. I have some Minolta maxxum "G" lenses and their converter and they do good work.
