Canon 1.4 teleconverter

 Will Canon's 1.4 teleconverter be compatible with an EFS 55/250 zoom lens on my 60D?

In that case "quality" is a 400mm lens which is the Canon EF 400mm f/5.6L USM Lens.  Its cost is about $1200 but it is worth every penny.

Based on the reviews I've read, I agree.

You don't know how many times I hear, "The review I read said, such and such, etc, and stuff!"  You need to read reviews with a eye on skepticism.  Just like the guy that wanted to know about MFT charts as a judge of a lens quality.  You can't.  It just doesn't tell you the suitability of a lens.  And, my friend, neither do all the reviews you read.  DXO is another lousy place to get quality data about a lens.

People you know and people that own the lens. People that actually use the lens for a good period of time are the ones to trust.

Well, reviews are a start but yes, you have to be skeptical about everything these days including people who are paid by the seller to "review" a product.  I want to find somebody near by who has the same lens and see if they will let me take a couple of pics on my 60D.

There is a local guy selling a recent model Canon 70-300mm who is going to let me try it out on my camera. He wants $350. We'll see how that goes.

Try before you buy!  A real good idea. 

[LesWurse]

I'll post the results.

Well my search for a 1.4 teleconverter ended with the purchase of a very clean, used Canon 70-300mm AF IS USM lens.  I tried it first at various settings and FL and couldn't find anything obviously wrong. Now we'll see about buyer's remorse after some more deliberate shootings.

I believe Kenko makes an EF-S compatible teleconverter. But, if you decide to purchase be sure to get it with return privileges since you may not be satisfied with picture quality.

Thank you. I'm not familiar with Kenko so I'll do some research.
