Extender for use with 80-200 f2.8L

[ken munn]

Just a quick question - is there a Canon 1.4 extender that will work with the forerunner of

today's 70-200?

Not a Canon one, because they have a protruding front element that does not fit that lens. Your next best bet is one of the WHITE ones sold by Tamron and Kenko.

I used a Tamron with mine when I had one. Performance wasn't bad but there was a small loss of sharpness. The rear element is right up against the back of the lens if I remember right, so (as stated above) the Canon TCs don't fit.

i use a kenko extender with my 80-200 and i have had outstanding results with it...in fact better than i expected

<p>As noted above, and in the 70-200 and 80-200 reviews in the static content, the 80-200 is not compatible with any of Canon's TCs. So you'll need to find a third-party TC which doesn't have a protruding front element. Given how good the 80-200 is, you don't want to buy the cheapest TC you can find; that's like buying a Ferrari and putting $10 tires on it.</p>

Thanks for your advice, looks like I need to shop off-brand.

It seems that both the sigma and tamron 1.4 are the best. Don't even try the 2X converters, none is good enough if you are used to the quality of your prime.

The Canon TCs have a protruding front element which is why they don't work on the 80-200/2.8L - the Sigma TCs also have a protruding front element and are not recommended for the 80-200/2.8L.

 

Either the Kenko Pro DG (~USD$195) or Tamron Pro (~USD$180) are the usual 'quality' TC of choice for the 80-200/2.8L.

 

Kenko's 1.4x recently received an update (designated "DG") that Kenko says offers better lens coatings to fight flare - the new Kenko is black, while the Tamron is white... The older Kenko Pro was white.
